Software Engineer | AI × Cybersecurity | London, Hybrid
Build the product behind AI agents that find vulnerabilities before attackers do.
We’re recruiting for an early-stage cybersecurity startup building autonomous AI agents that discover and prove security vulnerabilities in real customer environments. With $4 million in pre-seed funding, paying enterprise customers and real revenue, the team is now growing—and looking for a Software Engineer who enjoys building exceptional products across the stack.
This is an opportunity to shape the product, architecture and engineering practices while working closely with customers and a small, experienced team.
What you’ll build
You’ll turn complex agent discoveries into clear, useful experiences that security teams rely on: investigating findings, reviewing evidence, managing assets, scheduling scans and reporting results.
Your ownership will span the full journey:
- Build intuitive interfaces with TypeScript, React and Next.js.
- Develop Python backend services, REST APIs and relational data models.
- Take features from customer conversations through design, implementation and production.
- Own testing, deployment, monitoring and improvements after launch.
- Use AI coding agents thoughtfully—and help improve the workflows, evaluations and guardrails around them.
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.
What we’re looking for
- Experience shipping software used by real customers, with meaningful hands-on work across frontend and backend.
- Strong TypeScript, React and Next.js skills, with attention to usability, performance and polish.
- Solid backend and API engineering fundamentals; Python experience is particularly valuable.
- Confidence with SQL and relational databases, ideally PostgreSQL.
- Practical experience using AI development tools such as Claude Code, Cursor, GitHub Copilot or similar, with careful review and verification.
- The initiative to clarify an ambiguous problem, make sensible decisions and take ownership through delivery.
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Experience with B2B SaaS, data-heavy interfaces, cloud infrastructure, Docker or agentic AI would be a bonus. Cybersecurity experience is welcome, but curiosity about the domain and a willingness to learn matter too.
Why this opportunity?
- You’ll work on technically challenging problems with visible customer impact.
- You’ll have a meaningful voice in what gets built and how—and the chance to help shape an ambitious product while the team is still small.
