Lead Software Engineer

Are you the kind of Lead Software Engineer who enjoys taking a fairly messy collection of systems, data feeds, portals, and legacy platforms and gradually turning it into something modern, scalable, and genuinely slick? We're working with a leading technology company that is building towards a much more unified product and data ecosystem across multiple life-event and data services, with a long-term vision for a single, scalable platform experience.

  • Collaborate closely with Product, Data, and third-party engineering teams to ensure technology drives product value.
  • Contribute to shaping the direction of a modern platform with both greenfield development and legacy system modernisation.
  • Focus on building business-critical platforms, customer portals, subscription systems, or data-heavy products.

What You'll Need

  • Strong background as a Senior/Lead Software Engineer with deep experience in .NET, Azure, and SQL.
  • Experience with modern backend architecture and some exposure to frontend frameworks like React or Angular.
  • Proven ability to untangle and modernise legacy systems and architectures.
  • Commercial mindset, understanding the importance of technology in achieving business outcomes.
  • Comfortable engaging with cross-functional teams and external engineering partners.
  • Eligibility to work in the UK and availability for occasional in-person meetings in London.

What's On Offer

  • Opportunity to significantly impact the architectural direction of a unified product and data ecosystem.
  • Engaging work environment with the challenge of transforming complex systems into slick, modern solutions.
  • Role offering a blend of greenfield thinking and complex problem-solving in a dynamic tech landscape.
