Curious about what's next?

So are we. Join Compare the Market and help to make financial decision making a breeze for millions.

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.

We'd love you to be part of our journey.

As a Staff Engineer, you will play a pivotal role in shaping the technical foundations that enable the rapid development and scaling of new customer products and propositions across Compare the Market. You'll define and drive the architecture, standards, and engineering practices that underpin our product platforms, ensuring they are scalable, secure, resilient, and designed for long-term growth.

Operating as a force multiplier across multiple engineering teams, you will partner closely with product, engineering, architecture, and business leaders to turn strategic opportunities into robust technical solutions. You'll help accelerate the delivery of new customer experiences by building reusable capabilities, shared services, and platform components that empower teams to innovate quickly and safely.

We work agentically, with Spec Driven Development as our pattern of choice: clear specifications drive how we design, build, and verify software alongside AI-assisted tooling. You'll help shape and scale this way of working across our product platform estate.

What you'll be doing

• Own and deliver end-to-end technical outcomes for new product platforms and shared capabilities, ensuring alignment with business objectives and long-term strategic goals.
• Define, evolve, and communicate technical strategy, target architectures, domain roadmaps, and engineering guardrails that support the rapid creation and scaling of new products.
• Champion and scale our agentic, Spec Driven Development operating model, leveraging specifications and AI-assisted tooling to improve engineering quality, consistency, and delivery speed.
• Design and implement platform capabilities, services, APIs, and integration patterns that enable product teams to build and launch new customer propositions efficiently.
• Lead the technical discovery and definition of emerging product opportunities, helping teams navigate ambiguity and make informed architectural decisions.
• Drive initiatives that simplify the technical estate, reduce duplication, increase platform adoption, and create reusable building blocks across the organisation.
• Take end-to-end accountability for significant technical decisions, balancing customer value, engineering quality, scalability, speed, cost, and risk.
• Act as a technical leader and escalation point for complex platform, architecture, or delivery challenges.
• Evaluate and introduce new technologies, frameworks, and approaches that support innovation, experimentation, and future business growth.
• Raise engineering capability by mentoring senior engineers and supporting the development of architectural thinking, technical leadership, and decision-making.
• Partner closely with engineering managers, product leaders, architects, and stakeholders to align technical direction with strategic business outcomes.
Contribute to organisation-wide engineering standards, best practices, and communities of practice, influencing through expertise and leadership.

What we'd like to see from you

• Extensive hands-on software engineering experience, with a strong track record of designing and delivering scalable platforms, products, or complex distributed systems.
• Strong experience defining platform architectures, shared services, APIs, integration patterns, and reusable capabilities that enable multiple teams to deliver efficiently.
• Proven experience owning technical outcomes across multiple teams, programmes, or domains, influencing strategic direction beyond direct reporting lines.
• Deep understanding of software architecture, cloud-native technologies, distributed systems, reliability, observability, security, and performance engineering.
• Experience designing platforms that support rapid product innovation, experimentation, and scalable growth.
• Strong ability to navigate ambiguity and make sound technical decisions within evolving business and product environments.
• Practical experience applying AI-assisted tooling and agentic ways of working, ideally with Spec Driven Development or a comparable specification-led approach, alongside a clear perspective on scaling these practices effectively.
• Experience establishing engineering standards, governance, and technical guardrails whilst empowering teams to move quickly and independently.
• Strong stakeholder management skills, with the ability to influence senior leaders and align technical strategy to business priorities.
Demonstrated contribution to organisation-wide technology standards, architectural direction, and engineering communities of practice.
