Lead Analytics Engineer (6-month contract) United Kingdom (Hybrid)

Most money apps talk at you. Cleo talks back

We're not building another finance app. We're building the world's first AI financial assistant, one that actually understands your money and makes you better at it, and we're changing the world's relationship with money in the process for everyone, whatever their background or balance.

The proof: profitable, fast-growing, a unicorn with over $300M in ARR, and millions of people who now feel differently about their money.

We love original thinkers who challenge the status quo. We move fast, tell the truth, and there's nowhere to hide from good work here. If that excites you more than it scares you, you'll fit right in.

Meet the team

Here at Cleo, we have ~200 Engineers organised into Pillars. Our stack spans a Ruby on Rails monolith, a single React Native (TypeScript) app frontend, Python for machine learning services, and PostgreSQL, all hosted on AWS and shipped through Kubernetes - backend goes out multiple times a week, app releases to Google and Apple at least weekly. To thrive here, our engineers proactively use our Engineering Principles to guide daily decisions, take ownership of problems beyond their own squad to drive broader impact, and actively drive their own learning, development, and growth.

About the role

We are looking for a Lead Analytics Engineer, 6 month FTC to own the architecture and modelling for this work. You will partner with the teams responsible for our People systems, data platform, security and privacy, turning source data into trusted datasets that People Analytics and leadership can use. You’ll be responsible for:

• Design and build trusted data models for hiring/ATS data (Ashby) and talent/performance data (HiBob), including source mappings, keys, history, and reconciliation

• Strengthen the core employee model to reliably represent employees, jobs, teams, managers, and change over time

• Integrate engagement and survey data into the People data foundation in a consistent, reusable way

• Set clear model boundaries, grain, naming, tests, documentation, and data contracts across the People domain

• Identify and resolve duplicate, legacy, or conflicting People models without silently breaking downstream use

• Design a secure architecture for compensation, workforce cost, and other highly restricted fields, favoring masked, aggregated, or purpose-specific outputs over broad raw-data access

• Build a People data access-audit layer that attributes restricted queries to a named identity, retains evidence, and alerts owners to unauthorized or high‑risk access patterns

• Partner with Security, Privacy, Finance, Reward, and business owners to agree access rules, disclosure controls, and acceptance criteria before restricted data is used

• Create a small set of governed workforce measures and datasets for leadership reporting, using native People‑systems reporting where it already suffices

• Add tests, monitoring, failure routes, runbooks, and handover documentation so permanent owners can operate and evolve the work post‑contract

• Enable People Analytics to focus on workforce and hiring questions by providing reliable, secure, and reusable data foundations

What we're looking for

• Significant production Analytics Engineering experience, including technical leadership for a critical data domain

• Expert SQL and dbt, with strong judgement across source, staging, intermediate, mart, and semantic‑layer design

• Experience making architectural decisions on grain, history, slowly changing dimensions, incremental strategies, legacy boundaries, and model contracts

• Experience leading a source‑system migration or cutover while preserving history and reconciling outputs

• Strong data security and governance experience: named access, least privilege, restricted schemas, masking/column controls, and auditable use of sensitive data

• Experience using warehouse access and query logs to build monitoring, investigation evidence, or alerts

• Strong Git, PR review, testing, documentation, and production‑support habits

• Ability to explain technical choices and trade‑offs clearly to Analytics, Security, and non‑technical business owners

• Track record of leaving a complex data domain maintainable after handover

• Sound judgement and discretion with confidential employee, compensation, and performance information

• Nice to have HiBob or Ashby experience (or another HRIS/ATS), alongside engagement or survey data experience and data experience, incl. effective‑dated employment history

• Familiarity with Redshift, Airflow, Fivetran, Lake Formation, or similar
