Head of Data (Remote) in London

We combine deep practitioner knowledge of financial markets with cloud-scale data infrastructure to power proprietary derivatives analytics, portfolio construction, and risk tooling for some of the largest names in finance.

You will own our data strategy and roadmap while staying close enough to implementation to unblock your team, make architecture decisions with conviction, and ship code yourself when it matters.

You will manage a team of 3 data professionals today, with a hire planned this year. This is a high-profile role that reports directly to the CEO and includes hiring, performance review and team development responsibilities.

• Set and evolve the data strategy and roadmap in line with company priorities, balancing quick wins with scalable foundations.
• Lead the data team (currently 3 people), including hiring, performance reviews, coaching, and day-to-day delivery management.
• Stay hands-on: design, build, and maintain data pipelines, datasets, and internal tooling that support quantitative research and product development.
• Establish and own data quality, availability, and coverage metrics (KPIs), along with monitoring and alerting to keep data reliable.
• Partner closely with quantitative researchers, software engineers, product owners, and the business to deliver end-to-end data capabilities.
• Improve data engineering standards and practices (testing, code quality, documentation, and operational excellence) to help the team scale sustainably.

Clear quality/availability/coverage KPIs are defined, visible, and used to guide priorities. Incidents and manual fixes drop through better validation, monitoring/alerts, and clear ownership. Strong data engineering practices are the default: testing, code review, documentation, and operational ownership. Cost and performance are managed intentionally, with visibility into drivers and explicit trade-offs—without hurting reliability.

You have 5–10+ years of experience in data engineering, with at least 2 years leading or managing a team—guiding, motivating, and developing colleagues to deliver shared outcomes. You have experience working with financial datasets, ideally including market data feeds, derivatives reference data, and time-series pricing or similar domains.

You can align data initiatives with overarching business strategy, translating business priorities into a clear data roadmap your team can execute. You have deep experience designing, building, and operating production data pipelines, including owning reliability, monitoring, and failure recovery for orchestration systems such as Apache Airflow (or equivalent).

You are fluent in modern data and cloud ecosystems, with hands-on experience (or the ability to ramp quickly) in technologies such as Iceberg, Spark, PostgreSQL, and cloud-native infrastructure on AWS (or equivalent). You write clean, readable, and testable Python code, applying sound abstractions, naming, and review discipline to build systems that scale beyond the first version.

You bring strong analytical and problem-solving skills and can communicate ideas clearly—both in writing (e.g. concise design documents) and in discussion with engineers, product owners, and business stakeholders. You exercise pragmatic judgment: knowing when to build robust foundations and when a well-scoped, pragmatic solution is the right trade-off, and you can converge when many possible solutions exist.

You work well within a team and believe in open discussion, inclusion, and diversity. A high university degree in Computer Science, Mathematics, Engineering, Physics, or similar.

Part hybrid work policy - min 4 days a week in office. Lean principles and Agile development practices. Continuous deployment across all microservices.
