Oxford Economics' data platform is entering a new phase of growth, with increased scale, visibility, and business importance. We are investing to improve resilience, scalability, and operational simplicity so teams across the business can innovate and deliver client value with confidence.
We are seeking an ambitious, self-motivated Principal Software Engineer to provide technical and strategic leadership for the Data team and shape the platform's evolution. This role exists to bridge technology and business priorities, set architectural direction, define reliability standards, and scale delivery practices to match our expanding data needs.
As a hands-on leader with a strong data and architectural focus, you will have impact both through direct contribution and the technical leverage you create. You will guide design decisions, improve system health, and embed reliability and operational excellence into how we build and operate.
Key Responsibilities- Partner with product, business, and executive stakeholders to align platform strategy with business goals, ensuring data capabilities support client value.
- Design, build, and evolve resilient data flows from internal and external sources through to client-facing products.
- Establish platform observability as a first class concern, ensuring issues are detected early, diagnosed quickly, and understood clearly across the team.
- Introduce and maintain data quality controls that prevent downstream disruption and build trust in platform outputs.
- Lead and de-risk migrations, setting patterns that ensure safety, repeatability, and minimal client impact.
- Own platform performance and cost efficiency, defining strategies that anticipate scale and guide technical decisions.
- Build and maintain backend services and APIs that power Databank products and internal workflows.
- Collaborate on security and access control patterns, including role-based access and data-level permissions.
- Improve developer experience and delivery practices (CI/CD, automation, tooling) that help teams move faster safely.
- Contribute to frontend systems where needed to ensure data is delivered effectively to customers.
- Significant professional experience delivering and evolving business-critical production systems end-to-end, with clear examples of platform-level ownership and long-term impact.
- Expert-level proficiency in C#/.NET and TypeScript, with demonstrated ability to lead architecture and implementation across complex production systems.
- Deep, hands-on SQL and analytical data platform experience, including designing schemas, building ingestion patterns, and optimising for large datasets on columnar databases (e.g. Snowflake and/or ClickHouse), with a strong understanding of performance and cost trade-offs.
- Proven track record of improving reliability and operability at scale, including observability, incident leadership, post-incident improvement, automation, and test strategy.
- Strong experience with cloud infrastructure and modern engineering practices, and the ability to apply them pragmatically to real production systems.
- Azure experience (or strong equivalent cloud experience).
