Job Description
Product focused Senior Software Engineer – High-Impact Software, Real Ownership
London - Onsite
Extremely competitive salary ranging between £100,000 to £200,000 depending on experience. Plus excellent benefits.
This isn’t a bog standard software engineering role!
I’m working with a product-led software company whose platform is used globally by highly technical users to solve real, complex problems in web security technology. They’re looking for Product focused Senior Software Engineers who care deeply about outcomes over output - engineers who want genuine ownership, autonomy, and the chance to build software that truly matters. The position leans more towards a back end engineer.
This role is perfect for engineers who started as Java developers but have grown to work across multiple languages, frameworks, and stacks. If you like solving problems, shaping products, and exploring new technologies, this role is for you.
This is a role for thoughtful engineers who want to shape what gets built, not just how it’s built.
What makes this role different?
You won’t be handed a backlog and told to crack on. From day one, you’ll:
Own problems end-to-end Talk directly to users and use insight to guide decisions Design, build, and evolve features used by a large, expert audience Be trusted to experiment, iterate, and make sensible trade-offs Ship meaningful work with real-world impact
It’s high-leverage work in a high-trust environment.
What you’ll be doing
Solving complex technical problems with creativity and sound judgment Working across the stack as an expert generalist (backend-leaning, but curious everywhere) Designing and shipping robust, user-ready features Collaborating closely with other engineers, designers, and product partners Sharing work early and actively inviting feedback Using modern AI tools (LLMs, copilots, agents) to improve developer workflows and explore user-facing product opportunities
What they’re looking for
This role suits engineers who are product-minded problem solvers, not just implementers.
You’ll likely bring:
Strong backend engineering experience (Java is ideal, but mindset matters more than ) Comfort working across different technologies (e.g. Java, .NET, Python, Go, microservices) Experience in product-led teams Confidence operating in ambiguity and owning problems through to impact A genuine interest in users, not just systems Curiosity about AI — and good judgment about when (and when not) to use it
Just as important as technical skill:
Growth mindset Openness to feedback Strong collaboration habits High personal standards for quality and clarity
Both technical excellence and cultural fit are critical — the bar is deliberately high.
Why consider this role?
Software with genuine purpose and global reach Real ownership and influence over product direction A culture of autonomy, trust, and continuous learning High standards paired with strong support Excellent compensation based on individual impact A collaborative, humble, and high-performing engineering team
If you’re a backend-leaning engineer who enjoys thinking deeply, building carefully, and working on problems that actually matter, this is well worth a conversation.
