Software Developer jobs in United Kingdom

Role: Senior Product Engineer

Location: Remote FIrst (UK)

Compensation: £140,000–£220,000 + equity

We’re working with an early-stage technology company building a new platform at the intersection of software infrastructure and modern AI-enabled development. The team is focused on creating tools that make it significantly easier for developers and organisations to build, ship, and operate complex systems safely and at scale.

The product is still early, but already seeing strong traction with demanding customers, and the company is now investing heavily in building out a small, exceptional engineering team.

• This is a rare chance to join at the very beginning of a new product initiative and help shape both what gets built and how it’s built. You’ll work in a fast-moving, founder-adjacent environment where engineering decisions directly influence product direction, customer experience, and long-term company success.
• This is not a narrowly defined role. It’s designed for strong generalists and product‑minded engineers who enjoy working across boundaries and taking real ownership.

• Build and evolve a core developer‑facing product from its early foundations.
• Work across backend services, APIs, and user‑facing interfaces to deliver cohesive product experiences.
• Collaborate closely with founders and early customers to turn ambiguous needs into well‑crafted solutions.
• Design and scale modern web infrastructure to support growing usage and increasingly complex workflows.
• Take ownership across the full product lifecycle — building, shipping, operating, supporting, and iterating.
• Continuously improve developer experience, usability, and reliability as first‑class concerns.

• A strong product engineering mindset, with experience owning meaningful features or systems end to end.
• Comfort operating in early‑stage, high‑ambiguity environments with minimal process.
• A track record of exercising full agency; identifying problems, proposing solutions, and driving them through to impact.
• The ability to learn quickly and work across the stack, from backend systems to frontend experiences.
• A preference for small, talent‑dense teams where individual contribution matters.
• Curiosity, pragmatism, and a craft‑oriented approach to building software.

• Modern web infrastructure and APIs.
• Strong backend foundations (experience in statically or dynamically typed languages). We use Golang
• Frontend development for developer‑facing tools and interfaces. We use Typescript
• Cloud‑native systems and production operations.
• Open standards, extensible systems, and developer‑first design principles.

• Join at the ground floor of a new product with real momentum.
• Work directly with experienced builders who have scaled products before.
• High autonomy, high trust, and meaningful influence over product and technical direction.
• Solve abstract, hard problems that sit at the core of modern software development.
• Competitive compensation and equity aligned with early impact.

If you’re excited by the idea of shaping a new product from first principles, working closely with experienced founders, and crafting developer experiences that truly matter, we’d love to hear from you.
