Job description
The opportunity We're looking for a Senior Developer/engineer who's genuinely ready for a senior role - someone who can own the full software lifecycle, shape technical direction, and raise the bar for the team around them. This isn't a stepping stone. It's a role where your experience and instincts will matter from day one. You'll be working on platform systems that power one of the UK's biggest gaming sites - everything built in-house, with real complexity and real stakes. You'll be expected to drive quality, influence architecture decisions, and be a technical reference point for your peers. But you'll also be coding - we're not looking for someone who's stepped too far from the work. The best senior developers here do both. What you'll be doing - Owning the full software delivery lifecycle - from requirements through to production - Designing and delivering robust, scalable solutions in C# across tombola's platform - Driving engineering standards - code quality, testing practices, documentation - Influencing technical direction and contributing to architectural decisions - Mentoring and coaching developers at all levels - Leading code reviews and pair programming sessions - Working closely with stakeholders and non-technical colleagues to shape requirements - Monitoring application health and leading performance investigations - Contributing to agile ceremonies - standups, sprint planning, technical refinements - Ensuring compliance and regulatory considerations are built into delivery What we're looking for - Proven, senior-level C# skills - we're looking for someone exceptional here - Strong knowledge of the .NET ecosystem - both legacy frameworks and modern .NET - Experience owning work end-to-end, from requirements through to live systems - Deep understanding of testing methodologies - unit, integration, and beyond - Ability to design software to a high technical standard, collaboratively - Experience mentoring others and influencing team direction - Excellent communication across technical and non-technical audiences - Understanding of compliance, regulations, and how they affect software delivery Nice to haves - SQL and data layer experience - Experience working across both backend and frontend codebases - Involvement in hiring and technical interviewing Why tombola? At tombola, senior developers have genuine influence. Technology decisions are never handed down from above - they're made by the people closest to the work. You'll have real autonomy, real ownership, and the chance to help shape how we build for years to come. We're a business that's genuinely driven by technology. Every product, every system, every feature - built in-house. That means your work has real impact, and the team you'll join knows and cares about that. We've also got great benefits. Head to our careers site to see the full picture. At tombola we know that our differences make us stronger and that thinking differently is key to long-term success. We work hard to create a culture of inclusivity where everyone is free to be themselves. We welcome applications from all backgrounds. JBRP1_UKTJ
