Software Engineer required for Derry
3 days PW in Office – Hybrid and Condensed.
About Our Client
Our client is a fast-growing technology company based in Derry, delivering mission-critical, ISO 27001-certified software for UK Election campaigns. Having successfully delivered against multiple UK election cycles, they are now entering a significant growth phase, with their client base forecast to expand substantially over the next 12–18 months.
This is a genuinely AI-first engineering culture — not as a buzzword, but as the operating standard. The team builds using AI agents day-to-day, and this hire will be central to embedding that practice across the function as the business scales.
It is a rare opportunity to join a small, high-trust team building regulated, high-stakes software, with real autonomy and a direct line to the CEO.
They require a Software Engineer to join our engineering team. Following the successful delivery of the UK General Election and Local elections, our client base is forecast to grow significantly over the next twelve to eighteen months, and we need solid engineers who can ship code, work independently, and grow with us.
You will build software using AI agents, contribute to code reviews, and take ownership of features end-to-end. AI-first engineering is how we aspire to work. You do not need to be fluent with AI tooling already; but you will be expected to dive into AI-first workflows and figure it out.
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.
The role reports to the Head of Engineering. You will work closely with our operations and sales colleagues to understand what we are building and why.
What you will do
- Ship features end-to-end using AI agents, from design through to production.
- Take ownership of components and projects without needing constant direction.
- Contribute to code reviews and architectural discussions.
- Maintain and improve the engineering practices around you: testing, observability, CI/CD.
- Grow into more senior responsibilities as you develop and the team expands.
What we need from you
- Strong technical fundamentals. Comfortable across front-end, back-end API design, and database work. Can understand and create production quality experiences with technical and customer-minded care.
- Ability to work independently. You can pick up a piece of work, remove ambiguity, define what done looks like, and deliver it without close supervision.
- Composure and integrity. Direct, willing to admit mistakes, calm under pressure.
- Visible growth across your recent roles. Open to feedback and ready to push yourself.
- Comfortable working in a small startup environment.
- Drive towards AI-assisted engineering. We do not expect you to be fluent already, but we do expect you to be curious about it and quick to pick up new tooling. We are still embedding AI into our practices and need people that will help with that.
