1What this role really is

As a Senior Data Reliability Engineer, you're the person who makes sure our data isn't just there, but that it's actually right, all the time. You'll be designing and building the systems that keep our data clean, fresh, and trustworthy, preventing those awkward moments when a key report shows completely wrong numbers. This isn't just about fixing things when they break; it's about making sure they don't break in the first place. You'll work across our data platform, from ingestion to consumption, making sure every step is robust. Frankly, you're the guardian of our data's integrity, and that's a pretty big deal for a business that runs on numbers.

2What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Writing new Terraform modules from scratch to provision data infrastructure (e.g., new Snowflake warehouses, S3 buckets), and designing and building complex CI/CD workflows for deploying data infrastructure and testing changes.

Python (pandas, pytest)Advanced

Developing robust data processing applications, building custom libraries for data reliability, championing test-driven development (TDD) for data transformations, and scripting automated data validation checks.

3What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing inWhere you are nowThe step above
Technical Approach for a New Data Quality FrameworkProposes a solution based on existing templates, seeks approval from senior engineer.Designs a solution, gets feedback from peers, presents to manager for approval.Designs and implements the solution, making all technical choices, informs manager and relevant teams of the approach and rationale.
Incident Response CoordinationFollows playbook, executes assigned tasks, escalates issues to senior engineer.Leads diagnosis and initial fix for routine incidents, coordinates with 1-2 other engineers, escalates complex issues.Leads P1/P2 incident response end-to-end, coordinates multiple teams (Data Eng, Analytics, Upstream), makes real-time decisions on mitigation and communication, informs Director.
Defining New Data SLOs/SLIsHelps collect data for existing SLOs, understands their meaning.Proposes new SLIs for existing data assets, gets feedback from senior engineer.Designs and defines new SLOs/SLIs for critical data assets, gets agreement from data product owners, implements monitoring for them.
Mentoring/GuidanceSeeks guidance from senior team members.Provides informal guidance to new joiners on basic tasks.Formally mentors 1-2 junior engineers, conducts code reviews, provides structured feedback and development plans.

4How you'll be judged

The scoreboard, honestly: the hard targets, how often each one is actually looked at, and the quiet human signals that never make it onto a dashboard.

Tier-1 Data Asset Uptime
The percentage of time our most critical data assets (e.g., core financial models, customer segmentation data) are available and accurate.
Target · 99.9% uptime for all Tier-1 data assets

If our customer revenue data is unavailable or incorrect for 10 minutes in a month, that's a hit against this metric. You'll be tracking this closely.

Mean Time To Resolution (MTTR) for P1/P2 Incidents
The average time it takes to fully resolve high-priority data incidents, from detection to verified fix.
Target · Reduce MTTR for P1 incidents to under 60 minutes and P2 incidents to under 4 hours

A P1 incident hits at 10:00, you identify the root cause by 10:30, deploy a fix by 10:45, and verify resolution by 10:55. That's a 55-minute MTTR, which is spot on.

Reduction in Recurring Incidents
The percentage decrease in incidents that stem from the same root cause or a similar class of problem.
Target · 50% reduction in recurring incidents quarter-over-quarter

If we had 10 incidents related to 'schema drift' last quarter, we're aiming for 5 or fewer this quarter because of the preventative measures you've put in place.

Data Freshness SLO Adherence
The percentage of time critical data assets meet their defined Service Level Objectives (SLOs) for data freshness (how up-to-date they are).
Target · 98% adherence to defined freshness SLOs for all critical dashboards

Our 'Daily Sales' dashboard should update by 9 AM every day. If it's late once a week, that's a problem you'll need to solve to hit your target.

Quality of Incident Post-mortems
How thoroughly you investigate incidents, document root causes, and propose effective preventative actions, fostering a blameless culture.
  • Post-mortems are detailed, include a clear timeline, identify all contributing factors (not just symptoms), and lead to concrete, actionable follow-up tasks that are actually completed. You're seen as someone who helps the team learn, not just point fingers.
Effectiveness of New Reliability Patterns
Your ability to design and implement new data quality checks, observability monitors, or pipeline resilience patterns that genuinely improve data reliability.
  • New patterns you introduce (e.g., a data contract framework, an automated data validation suite) are adopted by other teams, demonstrably reduce incident frequency, and are praised for their robustness and ease of use. You'll get feedback like, 'That new monitor you set up saved us a massive headache last week.'
Mentorship Impact
How well you guide and develop junior Data Reliability Engineers, helping them grow their technical skills and problem-solving abilities.
  • Your mentees show clear progress in their technical capabilities, take on more complex tasks independently, and actively seek your advice. They'll tell their manager how much they've learned from you, and you'll see them successfully leading their own smaller incidents.
Proactive Risk Identification & Mitigation
Your knack for spotting potential data reliability issues before they blow up into full-blown incidents, and then implementing solutions to head them off.
  • You're regularly bringing potential risks to the team's attention (e.g., 'I've noticed this upstream system has flaky data types, we should add a robust schema check here'). You'll then lead the effort to put preventative measures in place, often before anyone else even realised there was a problem.

5Would you like it

The honest version. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You'll spend a good chunk of your day debugging intricate data flows, tracing errors through multiple systems, and figuring out why a number is 'wrong'. It's like being a detective, but with SQL and Python.

Spending an afternoon deep-diving into a subtle data discrepancy that turns out to be caused by a time zone mismatch between two different source systems.

Building Robust Systems

You'll get a real kick out of designing and implementing new monitoring, testing, and alerting frameworks that prevent future incidents. You're not just patching; you're building for durability.

Successfully implementing a data contract framework that prevents upstream schema changes from ever breaking downstream dashboards again.

Making a Tangible Impact

Your work directly translates into trustworthy data that drives business decisions. You'll see your efforts result in fewer data incidents, more accurate reports, and increased confidence from leadership.

After a major incident, you lead the post-mortem and implement changes that reduce data downtime by 20% in the next quarter, which gets noticed by the senior leadership team.

What frustrates people
  • The Upstream Surprise: An application team deploys a 'minor' change at 4 PM on a Friday that silently changes a key enum value, breaking the entire financial reporting pipeline over the weekend. Guess who gets paged?
  • Blame Catcher: Being the first point of contact for every 'weird' number on a dashboard, forcing you to spend hours proving the data pipeline is correct and the issue lies in the source or the user's interpretation.
  • The 'Quick Question' That Kills Your Day: A data scientist asks for help with a 'small' data discrepancy, which turns into a six-hour deep dive into a pipeline you didn't build, derailing all your planned preventative work.
  • Justifying Proactive Work: Fighting for resources to refactor a brittle pipeline or improve test coverage when leadership only wants to fund new, visible features. You often have to wait for it to break to get the buy-in you needed three months ago.
  • The Never-Ending Backfill: A logic bug is discovered that requires reprocessing three years of data. You spend the next two weeks babysitting a massive, resource-intensive job, hoping it doesn't fail at 98% completion.
  • The Politics of 'Truth': Proving with data that a specific department's operational process is flawed, and then having to navigate the political fallout when they challenge the validity of your data instead of fixing their process.
What this role does not give you
  • A predictable 9-to-5: Data incidents don't care about your schedule, especially if they hit critical systems.
  • Sole focus on greenfield development: A lot of your work will be improving existing, sometimes messy, systems.
  • Guaranteed deployment of every project: Sometimes, the business shifts, and your brilliant solution might get shelved.
  • Working in isolation: You'll be collaborating and communicating constantly with various teams.

6Who you work with

This role is absolutely critical for maintaining trust in our data. If our data isn't reliable, every decision made using it is suspect. You'll directly impact the accuracy of financial reports, the effectiveness of marketing campaigns, and the quality of customer insights. Essentially, you're building the bedrock for data-driven decision-making across the entire company.

Inside the business
  • Data Engineering Leads (for pipeline design and best practices)
  • Product Managers (who own the data products and features)
  • Analytics & BI Teams (the primary consumers of our data)
  • Upstream Application Engineering Teams (the source of much of our data)
  • Director of Data Platform (for strategic alignment and resource planning)
Outside the business
  • Data Observability Tool Vendors (e.g., Monte Carlo, Soda)
  • Cloud Platform Providers (e.g., AWS, GCP, Azure for infrastructure discussions)
  • Industry Peers (for sharing best practices and staying current)

7What you need before you start

Not a wish list. The things you would be expected to already have.

  • Proven experience (5-8 years) in data engineering, SRE, or a dedicated data reliability role, with a strong focus on data quality and pipeline robustness.
  • Deep expertise in at least one major cloud data warehouse/lakehouse platform (Snowflake, Databricks, BigQuery, Redshift) and a strong command of SQL.
  • Solid programming skills in Python, including experience with data manipulation libraries (pandas) and testing frameworks (pytest).
  • Demonstrable experience designing and implementing data quality frameworks and observability solutions (e.g., Great Expectations, Monte Carlo, Soda).
  • Experience with data orchestration tools (e.g., Apache Airflow, Dagster) and building idempotent, fault-tolerant data pipelines.
  • A track record of leading incident response for data-related issues, including root cause analysis and post-mortem facilitation.

8What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Data Architecture & Design Patterns

As our data landscape grows, you'll need to design more complex, resilient, and scalable data architectures. This moves beyond individual pipelines to entire data domains.

Data Mesh principles · Event-driven architectures · Data vault modelling · Chaos engineering for data

  • This quarter: Read 'Data Mesh' by Zhamak Dehghani and discuss its implications with your team.
  • Next quarter: Take a course on advanced data warehousing or data lakehouse architecture.
  • Within 6 months: Lead the design of a new data domain, applying advanced architectural patterns and reliability considerations.
  • Ongoing: Participate in architecture review boards, bringing a reliability-first perspective.

Quick win: Start documenting the current data architecture and identifying areas where design patterns could improve resilience.

Cloud Cost Optimisation for Data

Data platforms can get incredibly expensive, especially in the cloud. As a Senior DRE, you'll need to understand how your reliability choices impact cost and how to optimise for both.

Cloud billing models (e.g., Snowflake credits, Databricks DBUs) · Cost-aware pipeline design · Resource monitoring and governance · Data tiering and lifecycle management

  • This month: Dive into our cloud billing reports. Understand where our data costs are coming from.
  • Next quarter: Identify one costly data pipeline and propose optimisations that reduce its runtime or resource consumption.
  • Within 6 months: Implement a cost-monitoring dashboard for our data platform, with alerts for anomalies.
  • Ongoing: Regularly review query performance and storage usage, looking for opportunities to save money.

Quick win: Identify and delete any unused or stale data assets in our cloud storage – it's often 'low-hanging fruit' for cost savings.

9Staying current once you are in

What people here do to keep up
  • Attend industry conferences focused on data engineering, data quality, or SRE (e.g., Data + AI Summit, KubeCon, DataOps Summit).
  • Contribute to open-source data reliability projects or frameworks (e.g., Great Expectations, dbt, Airflow).
  • Participate in online courses or bootcamps on advanced data architecture, stream processing, or cloud-specific data services.
  • Join relevant professional communities or meetups (e.g., local Data Engineering meetups, SRE London).
  • Stay current with thought leadership from companies like Monte Carlo, Datafold, or industry analysts on data observability trends.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real: a big chunk of a Data Reliability Engineer's day is spent on repetitive tasks, sifting through logs, writing boilerplate tests, and drafting incident comms. What if you could offload a significant portion of that to AI? You'd have more time for the really interesting stuff—designing robust systems, proactive problem-solving, and actually preventing data downtime.

We're not talking about replacing you; we're talking about giving you a superpower. AI tools are rapidly maturing to handle the grunt work, freeing you up to be more strategic, more creative, and frankly, more impactful. Here's how AI can help you reclaim your time and elevate your game as a Senior Data Reliability Engineer:

Automated Anomaly Detection

Imagine not having to manually set thresholds for every single data quality metric. AI-powered monitoring tools (like Monte Carlo or built-in features in Snowflake) can automatically learn baseline data patterns—volume, freshness, distribution—and flag deviations without you lifting a finger. This means fewer false positives and catching real issues faster.

AI-Assisted Root Cause Analysis

During a data incident, time is money. AI can analyse logs, code commits, and pipeline metadata in seconds, suggesting likely root causes. It might tell you, 'Hey, a schema change in git repo X correlates perfectly with that data quality drop' or 'This latency spike in source API Y preceded the pipeline failure.' This cuts down manual 'detective work' significantly.

Generative Code for Data Tests

Writing comprehensive data quality checks can be a slog. Use an LLM (like GitHub Copilot or ChatGPT) to rapidly generate boilerplate code for dbt tests or Great Expectations. Just give it a schema and plain English rules (e.g., 'user_id should never be null and must be a positive integer'), and watch it spit out the code. This accelerates your test suite creation dramatically.

Incident Post-mortem & Comms Drafting

After an incident, you need to document everything and communicate clearly to stakeholders. Feed an AI a timeline of events, Slack conversations, and technical notes. It can generate a structured first draft of a blameless post-mortem report, including summary, timeline, impact analysis, and action items, plus a clear, non-technical summary for the wider business. Less writing, more learning.

The honest bit

You’ve started things before

Most of them were built for a room full of people who aren’t you. A cohort moves on whether or not your week allowed it, and by the third week the thing you’re behind on becomes the reason you stop opening it.

There’s no cohort here, and no timetable to fall behind. Before anything starts, Zavmo asks when you’re sharpest and how long you can realistically sit down for, then builds the sessions around those answers. A bad fortnight changes your pace. It doesn’t put you behind.

And you only pay once you start learning. Searching and planning are free, and you can cancel any time — so the cost of finding out is an afternoon, not a year.

What it costs

Less than one coaching session. Every month.

A single career-coaching hour costs more than a month of this, and it ends when the hour does. Zavmo doesn't. It's £70 a month, about £2.30 a day, for a companion that knows a Senior Data Reliability Engineer, works on the job you actually do, and keeps going at your pace rather than a timetable's.

  • Searching and planning stay free. You only pay when you start learning.
  • Your credits are yours. Regulated, and they don't vanish when a subscription ends.
  • Cancel any time and billing stops. No notice period, no minimum term.

Your path, personalised

You have the map. Walking it is the part we do together.

This route runs to 11 national skill standards. That is a real journey.

Zavmo shapes a learning experience as unique as you are. It fits how you learn, your pace and the work you already do. Every step stays benchmarked to recognised national standards. That’s the plan for becoming a Senior Data Reliability Engineer: personal to you, and it still counts. The first steps are free.
