Job Description
Principal Data Engineer
Function: Data / Technology
Location: London / Peterborough
At Compare the Market, we’re a purpose-driven business powered by tech and AI. We’re building high-performing, results-driven teams with the skills, mindset, and ambition to deliver outcomes at pace. Every role here plays a part in driving our mission forward, and we create an environment where you can bring your authentic self, grow a truly characterful career, and see the direct impact of your work on the lives of our customers.
We’ve carved a meerkat-shaped niche and we’re looking for ambitious, curious thinkers who thrive in a fast-moving, high-impact environment. If you love accountability, embrace challenge, and want to make a real difference, you’ll fit right in.
What You’ll Be Doing
* Own the Data Platform architecture and strategy, defining the long-term target state and setting clear standards and guardrails to ensure scalability, resilience, and cost efficiency.
* Set the engineering bar by establishing best practices across data ingestion, streaming, transformation, modelling, CI/CD, orchestration, testing, observability, and governance.
* Act as the senior technical authority across data engineering, influencing architecture decisions and leading the Data Engineering Community of Practice to raise capability across the organisation.
* Champion “data as a product”, ensuring datasets and platform services are reliable, discoverable, reusable, and governed with clear ownership and service expectations.
* Drive strategic technical direction while remaining hands‑on where it matters—reviewing designs, validating patterns, and guiding complex problem‑solving without becoming a delivery bottleneck.
What We’re Looking For
* Extensive experience in Data Engineering within modern, cloud-based data platforms.
* Deep expertise in streaming‑first architectures, with strong knowledge of batch processing approaches.
* Strong experience across AWS data ecosystems, Databricks, dbt, CI/CD practices, and orchestration frameworks.
* Proven track record of defining and implementing large-scale platform architecture and engineering standards.
* Strong understanding of data modelling, ingestion patterns, performance optimisation, observability, governance, and security.
* Experience influencing senior engineers and stakeholders across multiple teams without formal authority.
* Experience leading engineering communities of practice and raising technical standards at organisational scale.
* Ability to operate independently in complex, high‑impact environments.
