At Gemba Advantage, we design and build secure, user-centred digital products for critical public sector organisations across the UK. Our teams tackle complex, high impact systems, the kind where security, scalability, and seamless usability aren't just features, but absolute requirements.
We’re looking for a Senior Software Engineer who wants to shape meaningful systems, influence technical direction, and collaborate with capable people who care about doing the job properly. In this role, you will join two sister teams working on one of our most mission-focused projects, directly developing a suite of business critical systems and solutions that make a tangible impact.
You’ll help design modern cloud-native services, elevate engineering standards, and tackle genuinely challenging problems alongside our clients.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.

- Solve Real World Problems: Work directly with customers to untangle complex requirements and deliver high-value solutions.
What you’ll bring:
- Security Clearance: Active SC clearance with eligibility to obtain DV clearance (essential).
- Proven Track Record: Solid experience delivering production-grade systems in complex, highly regulated environments.
- Technical Depth: Mastery of at least one modern language (Java, TypeScript, Python, Go, etc.).

- Technical Leadership: Confidence influencing architecture decisions and driving continuous improvement across teams.
