3What this role really is

A Trust and Safety Engineer builds and improves systems that catch spammers, fraudsters and anyone breaking platform rules. The work involves digging into data, writing code, and finding ways to stop abuse before it spreads.

4What you'd actually use

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

Python (pandas, requests, basic scikit-learn) Intermediate

Writing and modifying scripts for data analysis, building API integrations for detection services, and prototyping simple machine learning models for abuse detection. You can debug existing code efficiently.

SQL (PostgreSQL, Presto, BigQuery/Snowflake) Intermediate

Writing complex queries with multiple joins and subqueries to pull data for investigations, monitoring rule performance, and extracting features for detection models. You're comfortable with large datasets.

Detection & Rules Engines (Sift, Arkose Labs, custom) Basic

Implementing and tuning rules within vendor platforms using their UI or simple scripting. You'll be learning how to design more complex logic as you go.

Cloud Infrastructure (AWS Lambda/GCP Cloud Functions, S3/GCS, IAM) Basic

Deploying simple functions for detection logic, storing data in cloud storage, and understanding basic IAM permissions. You're comfortable with the fundamentals of cloud services.

Observability & Monitoring (Datadog, Grafana) Basic

Building dashboards to monitor the health of specific rules or services you own, and responding to pre-configured alerts. You know how to tell if your systems are working as expected.

Case Management Tooling (ActiveFence, Spectrum Labs, internal) Basic

Using internal or third-party case management tools to investigate escalations from the operations team and analyse moderator decisions. This is where you'll see the real-world impact of your rules.

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
Rule Deployment Proposes rule changes; requires full review and approval from Senior Engineer. Independently deploys routine rule updates within assigned abuse areas after peer review. Consults Senior Engineer for high-impact or novel rules. Approves and deploys complex, high-impact rules. Defines deployment best practices for the team.
Tool/Library Selection Uses pre-approved tools and libraries. Proposes new tools to Senior Engineer for evaluation. Selects appropriate Python libraries or SQL functions for specific tasks. Proposes new tools or minor infrastructure changes (e.g., a new AWS Lambda function) to Senior Engineer for approval (up to £2K cost). Evaluates and recommends major new tools or technologies for team adoption. Approves infrastructure changes up to £5K.
Incident Response Actions Assists with data gathering and initial diagnosis under direct supervision. Does not take independent action. Independently diagnoses routine incidents within owned systems. Proposes and implements immediate containment actions (e.g., temporarily disabling a rule) after consulting with Senior Engineer. Escalates major incidents immediately. Leads incident response for moderate to severe incidents. Authorises and coordinates containment and remediation efforts across multiple teams.
Data Model Changes Suggests data improvements; requires Senior Engineer to design and implement. Proposes and implements minor changes to existing data models or new feature engineering pipelines, requiring peer and Senior Engineer review. Consults Data Architect for significant changes. Designs and implements significant changes to core T&S data models. Reviews and approves data model changes proposed by junior engineers.

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.

Rule Precision
The percentage of times your detection rules correctly identify bad behaviour versus flagging legitimate users or content.
Target · >99.95% on rules shipped

If your new spam rule flags 10,000 items, and only 5 of those were legitimate user posts, that's a 99.95% precision rate. Anything lower, and we'll be having a chat about user impact.

False Negative Rate for Owned Abuse Areas
How much bad stuff (e.g., specific type of spam, account takeover attempts) you miss that later gets identified by other means or human review.
Target · Reduce by 10% quarter-over-quarter for your assigned abuse type.

You're responsible for comment spam. If in Q1, 100 spam comments slipped past your systems, we'd expect that number to be 90 or less in Q2 thanks to your improvements.

Time to Resolution for Investigation Tickets
How quickly you can investigate and resolve tickets escalated from the Trust & Safety Operations team regarding potential system bypasses or new abuse patterns.
Target · Close 80% of investigation tickets within 48 hours.

An Ops analyst flags a new phishing attempt. You'd be expected to dig into the logs, identify the pattern, and propose a fix or new rule within two days, most of the time.

Code Quality & Maintainability
The cleanliness, readability, and test coverage of the code you write, as assessed during code reviews.
Target · <5 bugs found in code review per month; 90%+ test coverage for new features.

You submit a pull request for a new detection service. If your senior engineer finds only minor stylistic suggestions and the tests pass, you're hitting the mark. If they find critical logic errors, that's a problem.

Proactive Threat Identification
How often you spot new abuse patterns or vulnerabilities before they become a major problem, rather than just reacting to incidents.
  • You'll bring new attack vectors to team meetings, propose new detection methods without being asked, or share insights from industry forums. This isn't just about fixing what's broken
  • it's about finding what's about to break.
Collaboration with Operations
How effectively you work with the Trust & Safety Operations team to understand their challenges and translate them into engineering solutions.
  • Ops team members will tell us you're easy to work with, you listen to their feedback on rule performance, and you explain technical decisions clearly. You're not just throwing code over the fence
  • you're building solutions with them.
Documentation Clarity
The quality and completeness of the documentation you create for your rules, services, and investigations.
  • Other engineers or Ops team members can easily understand your rule logic, service architecture, and investigation findings without needing to ask you for clarification. Future-you will also thank present-you for this.
Incident Response Participation
Your ability to contribute effectively and calmly during active abuse incidents, helping to diagnose and contain the problem.
  • During an incident, you'll be able to quickly pull relevant data, suggest potential fixes, and communicate your findings clearly to the team. You'll be a reliable pair of hands when things get hectic.

7Would you like it

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

What people enjoy
Making a Tangible Impact on User Safety

You'll see direct results of your work: a reduction in spam, fewer fraudulent accounts, or a cleaner comment section. This isn't abstract; you're actively protecting real people.

After deploying your new rule, you see the daily volume of reported phishing links drop by 30%. That's a direct win for user safety.

Solving Complex, Evolving Puzzles

Every day presents a new challenge. Attackers are constantly adapting, so you're always learning, always strategising, always trying to outsmart them. It's a never-ending intellectual puzzle.

You spend a week tracking a new botnet's behaviour, finally cracking their pattern and deploying a counter-measure. The satisfaction comes from outsmarting a clever adversary.

Working at the Forefront of Online Security

You'll be dealing with cutting-edge abuse techniques and building sophisticated defences. This role keeps you sharp and at the top of your game in a rapidly changing field.

You're researching a new type of 'deepfake' scam and proposing how our systems could detect it, pushing the boundaries of what's possible in T&S.

What frustrates people
  • The 'Whack-a-Mole' Reality: You'll spend a month building a sophisticated defence for one abuse vector, only to see attackers immediately pivot to two new, simpler ones. The work is never 'done'.
  • Policy's Unenforceable Mandates: Being handed a new community policy from the legal/policy team that sounds great on paper but is technically ambiguous or impossible to enforce at scale with acceptable accuracy.
  • The Blame for False Positives: When you inevitably block a legitimate power user or a journalist with a new rule, you (not the policy team) will be the one explaining the technical failure to an angry product manager.
  • Emotional Burnout: Even if you're not a frontline moderator, you are constantly immersed in the data patterns of the worst human behaviours. This takes a psychological toll over time.
What this role does not give you
  • A static, predictable workload – priorities can shift quickly based on new threats.
  • Complete isolation from the 'bad' side of the internet – you'll be exposed to it regularly.
  • A role where every single piece of your code goes live and stays live forever – some experiments won't work out.

8Who you work with

This role directly impacts our platform's integrity and user trust. Your work helps to reduce the amount of harmful content and bad actors, which in turn protects our brand reputation and ensures a positive user experience. Get it right, and we keep our users happy and safe; get it wrong, and we risk losing them to competitors or facing regulatory headaches. It's pretty fundamental, honestly.

Inside the business
  • Product Managers (especially those building new features)
  • Trust & Safety Operations Team (the folks who review what you flag)
  • Data Analysts (for deeper insights and reporting)
  • Legal & Policy Teams (who define the rules you're enforcing)
Outside the business
  • Security Researchers (sometimes you'll work with them to understand new threats)
  • Platform Users (ultimately, you're protecting them)

9What you need before you start

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

  • Solid understanding of software engineering principles and best practices.
  • Proven ability to write clean, maintainable, and well-tested code in Python or a similar language.
  • Experience with data analysis and querying large datasets using SQL.
  • A genuine curiosity about how systems can be abused and a drive to prevent it.
  • Ability to work effectively in a team, including participating in code reviews and collaborating on solutions.

10What to practise next

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

Advanced Data Streaming & Real-time Processing

Essential for future readiness in this role.

Event-driven architectures (Kafka, Kinesis, Pub/Sub) · Stream processing frameworks (Flink, Spark Streaming) · Low-latency data storage (Redis, DynamoDB) · Windowing functions for time-series analysis

  • This month: Take an online course on Kafka or AWS Kinesis fundamentals.
  • Month 2: Prototype a simple real-time detection rule using a streaming framework (e.g., a velocity check on account creation).
  • Month 3: Work with a senior engineer to integrate one of your existing batch rules into a real-time pipeline.
  • Month 4: Read case studies on how other companies use real-time T&S systems.

Quick win: Start looking at our existing real-time data pipelines. Understand what data flows through them and how it's currently used. Ask questions!

Graph Databases for Abuse Detection

Essential for future readiness in this role.

Graph theory fundamentals (nodes, edges, properties) · Cypher or Gremlin query languages · Graph algorithms (e.g., PageRank, community detection) · Use cases for fraud and abuse detection

  • This month: Explore Neo4j or Amazon Neptune documentation and tutorials.
  • Month 2: Model a simple abuse scenario (e.g., a fake account network) in a local graph database.
  • Month 3: Try to implement a basic graph query to find suspicious connections.
  • Month 4: Discuss with your senior how graph databases could solve one of our current hard-to-detect abuse problems.

Quick win: Think about an abuse pattern you've struggled to detect with SQL. How would you represent that as a graph? Just sketching it out is a great start.

11Staying current once you are in

What people here do to keep up
  • Regularly participate in online security forums or communities (e.g., Hacker News, Reddit's r/netsec) to stay updated on new threats and attack techniques.
  • Attend relevant industry conferences or webinars (e.g., RSA Conference, Black Hat, local OWASP meetups) to network and learn from peers.
  • Contribute to open-source projects related to security, data analysis, or abuse prevention – it's a great way to show off your skills.
  • Take online courses or specialisations in areas like machine learning for security, advanced SQL, or cloud architecture.
  • Engage in 'capture the flag' (CTF) challenges or hackathons to hone your problem-solving and security instincts.

    • Cross-team Influence You'll be regularly influencing product and engineering decisions beyond your immediate team.
Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of what we do as Trust and Safety Engineers involves digging through data, writing boilerplate code, and trying to keep up with ever-evolving threats. What if you could offload some of that grunt work to AI and focus on the really interesting, strategic stuff? That's exactly what we're doing here.

We're building an AI Hub specifically for our technical teams. It's not about replacing you; it's about giving you superpowers. Imagine having a co-pilot that helps you write rules, summarise incidents, and even prototype attacker behaviour in minutes instead of hours. This isn't some far-off future; it's what you'll be using day-to-day.

Rule Generation Assistant

Use our internal LLM, trained on our policies, to translate a new policy update (e.g., 'no more crypto airdrops') into a draft of the required SQL, Python, or rule engine logic. It'll get you 80% of the way there, letting you focus on the tricky edge cases.

Incident Pattern Synthesizer

Feed thousands of unstructured incident reports, user flags, and moderator notes into an LLM. It'll summarise emerging attack patterns, highlight key attacker terminology, and point out common circumvention techniques, saving you hours of manual analysis.

Adversarial Code Prototyper

Need to test a new defence? Use a coding assistant to rapidly prototype scripts that mimic potential attacker behaviour. Just tell it: 'Write a Python script using Selenium to automate account creation and post 100 comments with slight variations.' Boom, instant test harness.

Post-Mortem & Documentation Drafter

Provide an AI tool with a timeline of events, key metrics (like accounts impacted), and links to dashboards. It generates a structured first draft of a post-mortem document, including summary, root cause analysis, and action items, freeing you from tedious writing.
