London (4 Days a Week)
£100,000–£170,000 + Significant Equity
Most founding engineering roles are about building a product. This one is about building the company.
We're working with a well-funded security technology startup that's building the software platform powering the next generation of intelligent, autonomous systems. Having secured backing from some of the world's leading technology investors, they're now looking for a Founding Software Engineer to help shape both the product and the engineering culture.
You'll join a small, exceptionally talented team where your work will directly influence the technical direction of the business. From architecting new features to solving complex engineering challenges, you'll have ownership from day one.
What you'll be doing
- Designing and building core platform capabilities from the ground up
- Developing scalable backend systems and APIs
- Working across AI, distributed systems, and cloud infrastructure
- Collaborating closely with product, design, and customers to solve real-world problems
- Taking features from idea through to production
- Helping define engineering standards, architecture, and technical direction
- Contributing across the stack where needed in a fast-moving environment
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.
We're looking for engineers with
- Strong commercial software engineering experience
- Excellent coding skills in Python, Go, Rust, Java, or C++
- Experience building scalable distributed systems or backend platforms
- A product mindset with the ability to solve complex technical problems
- Confidence working in a fast-paced startup environment with lots of ownership
Experience with AI, machine learning, cloud infrastructure, or security-focused products would be beneficial, but isn't essential.
