About us
Encord is the universal data layer for AI that helps 300+ AI teams train and run models on the right data. Our platform indexes, curates, annotates, and evaluates data across the full AI lifecycle, from development through production.
Trusted by Woven by Toyota, AXA, UiPath, Zipline, and more. We're an ambitious team of 100+ working at the frontier of AI and have raised $60M in Series C funding from Wellington Management, CRV, Next47 and Y Combinator.
The role
We're hiring a Quality Systems Lead to own how Encord measures the quality of the human data we deliver to frontier AI labs, physical AI companies and enterprise AI teams — the standard itself, the systems that evaluate against it, and the audit function that produces the ground truth behind both. Data quality is what our customers buy. As we scale across data types — image and video, document, medical, LLM evaluation, robot teleoperation, egocentric capture — quality coverage cannot scale linearly with headcount. So this role has two halves that make each other work. You will build automated evaluation: model-assisted and LLM-based screening, agreement analysis at scale, anomaly and drift detection across annotation output. And you will build and run a dedicated audit team of around ten specialists in India, whose judgements become the labelled ground truth that trains and calibrates that automated layer. As coverage automates, the audit team moves up to the cases models can't judge and to generating gold sets for each new data type we take on. It is an unusual combination — engineering and consistent QC operations in one person — and it is the combination the job needs. You will also have an advantage your counterparts elsewhere in the industry don't: Encord owns the platform this work runs on, so the measurement you build can become native capability in the product rather than internal tooling.
What you'll do
- Build automated dataset quality evaluation and root-cause detection — model-assisted and LLM-as-judge screening, agreement analysis at scale, anomaly and drift detection across annotation output
- Hire, train, calibrate and manage a dedicated audit team of around ten specialists based in our India operation, held to inter-rater agreement and catch rate rather than volume audited
- Turn audit output into labelled ground truth that trains and validates the automated layer, and manage the ratio of automated to manual coverage deliberately over time
- Own the quality standard for every data type we deliver — written rubrics with worked edge cases, golden sets, and acceptance criteria agreed with the customer, alongside the Special Projects lead, before the first batch ships
- Build scoring systems that rank annotator and reviewer performance and feed routing, staffing and offboarding decisions
- Set the pass thresholds that certification gates on, so nobody works a project queue without having demonstrated they meet the standard
- Report quality KPIs to leadership, and into the reporting our Special Projects leads take to customers: accuracy against client spec, inter-annotator agreement, rework rate, cost of rework, and coverage
- Work with Project Management on remediation — you produce the measurement and the diagnosis, production owns fixing the project, and the standard stays independent of the people being measured
- Own the unit economics of quality: cost per audited unit, and the coverage you buy per pound spent
- Partner with Product and Engineering to bring quality measurement into Encord platform as native capability
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Who we're looking for
- You build and you operate. You'll write the evaluation pipeline, and you'll also run the weekly calibration session with ten auditors in another country
- Your instinct on a coverage problem is to automate it — you reach for a model, a heuristic or a better sampling design before you reach for more auditors
- Statistically literate in a practical way: sampling design, agreement statistics, and the judgement to spot a metric being optimised against rather than met
- You can hold a calibrated standard across a distributed team you don't sit with — you know that ten uncalibrated auditors produce ten standards
- A strong writer. Much of this job is producing rubrics a distributed workforce can follow without you in the room
- You hold a standard under commercial pressure, and you bring the evidence that makes it stick with a delivery team or a client
- Systems thinker: as interested in why a failure recurs across projects as in this project's defect rate

Experience requirements
- 4+ years owning both technical and operational outcomes in a data, AI or service delivery environment where quality was measured rather than asserted
- Hands-on Python and SQL. You build the analysis and the tooling rather than specify it for someone else
- Practical experience applying models to a quality or evaluation problem — LLM-as-judge, model-assisted QA, automated evaluation, anomaly detection or classifier-based screening
- Sampling methodology and agreement statistics (Cohen's and Fleiss' kappa, F1 against ground truth) applied to real production data
- Experience hiring, training and managing a team, ideally an audit, review or QA team, and ideally distributed
- Track record of building a quality framework or function, including the reporting leadership and customers run on
- Bonus: direct experience of annotation, evaluation or model-training workflows, and of what frontier AI labs accept as evidence of quality
- Bonus: a STEM degree, or a background in data science or research engineering
- Bonus: multilingual delivery and linguistic quality assessment
Why Encord
- Competitive salary, commission, and equity in a high-growth startup
- Strong in-person culture — most of the team works from our London office 4+ days/week
- 25 days annual leave + UK public holidays
- Annual learning & development budget
- Travel for customer visits, events, and conferences across the UK and Europe
- Company lunches twice a week
- Monthly socials & bi-annual team offsites
