3What this role really is

A data analyst assistant turns raw, sometimes messy, data into clear, useful insights for technical and business teams. The work means taking complex numbers and making them understandable, so teams have the right information to make decisions.

4What you'd actually use

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

SQL (PostgreSQL, MySQL) Intermediate

Writing and modifying `SELECT..FROM..WHERE..JOIN` queries, using `GROUP BY` and `ORDER BY` for data extraction and basic aggregation.

Excel (Advanced) Advanced

Mastering `XLOOKUP`, PivotTables, and Power Query for quick data cleaning, aggregation, and ad-hoc analysis. Yes, people still use Excel for critical stuff.

Tableau / Power BI Intermediate

Connecting to prepared data sources, building interactive dashboards from templates, and applying filters to help users explore data. You'll make data look good.

Python (pandas, Matplotlib) Basic

Running existing Jupyter notebooks, making minor script modifications for data loading and basic cleaning, and generating simple plots.

Jira / Confluence Intermediate

Updating tickets with your findings, documenting simple methodologies, and tracking your assigned tasks. It's how we keep organised.

5What 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 in Where you are nowThe step above
Data Extraction & Query Design Executes pre-written scripts; all new queries reviewed by supervisor. Independently designs and executes queries for standard requests; complex queries reviewed by Senior Analyst. Designs complex queries and data models; peer reviews for critical production code.
Data Cleaning & Transformation Follows explicit instructions for cleaning; supervisor validates results. Chooses appropriate methods for routine cleaning tasks; consults on novel data issues. Defines data cleaning standards and best practices; mentors others on complex transformations.
Dashboard Design & Maintenance Updates existing dashboards based on templates; supervisor approves changes. Designs new dashboards for specific teams using prepared data sources; manager reviews for alignment. Architects dashboard solutions for entire workstreams; responsible for performance and governance.
Stakeholder Communication Responds to direct questions; supervisor handles complex discussions. Communicates findings clearly to internal teams; escalates disagreements or complex interpretations. Leads discussions with stakeholders to define requirements and present findings; manages expectations.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Data Pull Accuracy Rate
The percentage of data extractions and reports you deliver that are free from errors or discrepancies.
Target · >98% accuracy on all data pulls

If you pull a sales report, the total revenue should match the official finance system within a tiny margin. Getting it wrong by £100K means someone's making a decision on bad data.

Standard Ad-Hoc Request Turnaround Time
How quickly you can fulfil typical, well-defined data requests from internal teams.
Target · Fulfill standard requests within 24 hours

A Product Manager asks for 'the number of new sign-ups last week, broken down by acquisition channel'. You should be able to get that back to them by the next day.

Query Revision Rate
The percentage of your SQL queries or analysis scripts that require significant changes after a peer or manager review.
Target · <2% of queries require major revisions

You submit a query for review, and your manager only suggests a minor optimisation, not a fundamental fix because you missed a join condition.

Dashboard Reliability
The uptime and data freshness of any dashboards you build or maintain.
Target · Dashboards owned by you have <1% downtime due to data issues

Your 'Daily Product Usage' dashboard is always showing the most recent data, and users can access it without errors. If it's broken, Product can't see what's happening.

Clarity of Communication
How well you explain your findings and methodologies to non-technical audiences, both verbally and in writing.
  • Stakeholders consistently understand your reports without needing follow-up questions. Your documentation is clear and easy to follow. You can explain a complex SQL query in plain English.
Proactive Problem Identification
Your ability to spot potential data inconsistencies or issues before they impact reports or business decisions.
  • You flag a potential data quality issue to the Engineering team before it breaks a dashboard. You notice an anomaly in a trend and investigate it without being asked. You question numbers that 'don't look right'.
Quality of Documentation
How well you document your code, queries, and analysis methodologies.
  • Your SQL queries are well-commented. Your Confluence pages explaining a new report are comprehensive and up-to-date. Someone else could pick up your work and understand it quickly.
Stakeholder Satisfaction
How happy the teams you support are with your responsiveness, accuracy, and helpfulness.
  • Teams regularly come to you directly for data requests. You receive positive feedback in informal check-ins or project retrospectives. People trust your numbers.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Puzzles

You enjoy the challenge of figuring out why a dataset isn't quite right, or how to combine disparate pieces of information to answer a tough question. Debugging a complex query feels like a win.

Spending an hour tracking down why a report's numbers don't match another, only to find a subtle date filter difference, and then fixing it.

Making an Impact

You get a real kick out of seeing your analysis directly inform a decision, whether it's a new product feature or a refined marketing strategy. You like knowing your work matters.

A Product Manager tells you that your latest user behaviour analysis helped them decide to prioritise a specific bug fix, and you see the positive impact in the next week's metrics.

Continuous Learning

You're always looking for new ways to improve your skills, whether it's optimising a SQL query, learning a new Python library, or understanding a different visualisation technique. You're never 'done' learning.

You take the initiative to learn about window functions in SQL because you know they'll make your queries more efficient, even if it's not immediately required for a task.

What frustrates people
  • You'll spend up to 80% of your time cleaning, validating, and restructuring messy data. Only 20% is the fun stuff, the actual analysis.
  • Someone will ask for 'data on performance' via Slack with no clear definition, no timeframe, and no objective. You'll have to play detective to figure out what they actually need.
  • Your project might be blocked for days because you're waiting for someone in IT to grant you `READ` access to one critical database table.
  • After you've delivered a brilliant analysis, the stakeholder will immediately ask for five new breakdowns, each requiring you to rewrite your queries from scratch.
  • A senior leader might insist on receiving a 1.5-million-row dataset in an Excel file, which you know will crash their computer and corrupt the data.
  • Halfway through a complex analysis, the project manager will tell you the core business logic has changed, making all your previous work invalid.
  • You'll present your findings, only to be told the numbers look wrong, and then discover the underlying data pipeline has been silently failing for a week.
What this role does not give you
  • A perfectly clean dataset to start with every time.
  • Complete autonomy over project direction (you'll be working within defined requests).
  • A quiet, uninterrupted environment for deep work every day (ad-hoc requests are common).
  • Guaranteed deployment of every piece of analysis you produce.
  • Direct management of a team (this is an individual contributor role).

8Who you work with

Your work ensures that our internal teams, especially Product and Engineering, have accurate, reliable, and timely data to make their day-to-day decisions. You're essentially the backbone for data-driven choices, helping us optimise everything from product features to operational efficiency. Without you, teams would be guessing, and that's not a good look for anyone.

Inside the business
  • Your Manager (for guidance and development)
  • Product Managers (for understanding user behaviour and feature performance)
  • Engineering Teams (for data quality issues and understanding system logs)
  • Marketing Team (for campaign performance and customer insights)
  • Sales Operations (for sales trends and pipeline analysis)
Outside the business
  • None directly in this role. Your work is primarily internal-facing.

9What you need before you start

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

  • A solid understanding of basic statistical concepts (averages, percentages, distributions).
  • Proven ability to write and debug SQL queries for data extraction and manipulation.
  • Experience cleaning and preparing datasets, ideally using Excel's Power Query or Python's pandas library.
  • Demonstrable experience building visualisations and dashboards in tools like Tableau or Power BI.
  • A logical and methodical approach to problem-solving, even when the data is messy.
  • The ability to communicate technical concepts clearly to non-technical people.

10What to practise next

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

SQL Optimisation & Advanced Functions

As datasets grow, inefficient queries can grind systems to a halt. You'll need to move beyond basic joins to write cleaner, faster code. Knowing window functions and CTEs will become essential for complex analysis.

Window Functions (e.g., `ROW_NUMBER()`, `LAG()`) · Common Table Expressions (CTEs) · Indexing Basics

  • This month: Start using CTEs for any query with more than two joins.
  • Month 2: Practice converting existing subqueries into window functions where appropriate.
  • Month 3: Read up on `EXPLAIN ANALYZE` in PostgreSQL (or similar for our database) to understand query performance.
  • Month 4: Ask a Senior Analyst to review your queries specifically for optimisation opportunities.

Quick win: Whenever you write a new query, challenge yourself to make it as readable and efficient as possible, even if it takes a bit longer initially.

Version Control (Git/GitHub)

As your Python scripts and SQL queries become more complex and shared across the team, manually tracking changes becomes a nightmare. Git is the industry standard for collaborative code development and will be expected for all analytical scripts.

Repositories & Commits · Branching & Merging · Pull Requests (PRs) & Code Reviews · Resolving Merge Conflicts

  • This month: Complete a free online tutorial on Git basics (e.g., 'Git Immersion').
  • Month 2: Start saving all your personal Python scripts in a local Git repository.
  • Month 3: Contribute a small, non-critical change to a team repository via a Pull Request (with guidance).
  • Month 4: Participate in a peer's code review, focusing on understanding their changes.

Quick win: Install Git on your machine and create a local repository for your personal projects. Get comfortable with `git add`, `git commit`, and `git push`.

11Staying current once you are in

What people here do to keep up
  • Regularly participate in online data challenges (e.g., Kaggle, DataCamp) to keep your skills sharp and learn new techniques.
  • Attend industry webinars or virtual meetups focused on data analytics or specific tools like SQL and Python.
  • Contribute to open-source projects or build a personal portfolio of data analysis projects on GitHub.
  • Read relevant blogs, articles, and books to stay up-to-date with best practices and emerging trends in data.

What's rising in its place

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Prompt Engineering & LLM Integration

Honestly, competitors are already using tools like ChatGPT to draft reports in minutes that used to take hours. Analysts who figure out how to effectively use these tools will simply outproduce their peers. It's not future-state; it's happening now.

  • Context Windows & Token Limits
  • Temperature Settings
  • Output Validation
  • Prompt Chaining

Basic Cloud Data Interaction

More and more of our data lives in the cloud (AWS, GCP). While you won't be an architect, knowing how to pull data from cloud storage or query a cloud data warehouse will become standard. It's where the data is, so you need to know how to get to it.

  • Cloud Storage Buckets (e.g., AWS S3, GCP Cloud Storage)
  • Basic Cloud Data Warehousing (e.g., Snowflake, BigQuery)
  • Authentication & Permissions

    • Basic data pipeline understanding and troubleshooting.
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 Analyst Assistant's job can be repetitive. Imagine having an assistant that handles the tedious bits, freeing you up for the interesting stuff. That's where AI comes in. We're not talking about replacing you; we're talking about making you way more effective.

Our Technical_roles department is embracing AI to help our data professionals work smarter, not harder. You'll get access to tools that automate the grunt work, allowing you to focus on deeper analysis, problem-solving, and actually understanding the 'why' behind the numbers. Think of it as having a superpower for your daily tasks.

Automated SQL Generation

Ever wish your brain could just spit out a SQL query? Now it almost can. You'll use an AI copilot to translate a plain English request—like 'Show me monthly active users by country for the last 6 months'—into a starter SQL query. You then validate and refine it, cutting down on typing and syntax errors.

Accelerated Data Cleaning

Cleaning messy data is a huge time sink. Imagine feeding a sample of a dirty CSV into an AI tool. It'll generate the Python (pandas) or Power Query code you need to standardise date formats, trim whitespace, and correct common misspellings. It's like having a data janitor that writes its own code.

Instant EDA & Chart Suggestions

After you've cleaned your dataset, you can upload it to an AI tool. It'll automatically perform exploratory data analysis, highlighting correlations, outliers, and even suggesting the most effective visualisations for your specific data. No more guessing which chart to use; the AI gives you a head start.

Smart Documentation & Summaries

Documentation is crucial but often a chore. Paste your final, complex SQL query or Python script into an AI assistant and ask it to 'Explain this query in simple terms and add comments to each CTE'. It automates the tedious but absolutely critical process of making your work understandable to others (and future you!).
