Backend Engineer – Java / Kotlin / Spring Boot
London – Hybrid (1 day per week)
Up to £100,000 + Share Options
Unfortunately, sponsorship cannot be provided
I'm working with a growing technology startup looking to hire a Backend Engineer to join its engineering team in London.
They're looking for someone who is genuinely strong technically – not just someone who has worked with the right technologies. You'll be joining a small, high-performing team where you'll have significant ownership over backend systems, contribute to architectural decisions and help shape how the platform develops as the business scales.
What they're looking for
The core requirements are:
- Strong, recent commercial Java experience
- Strong, recent commercial Kotlin experience
- Strong commercial Spring Boot experience
- Ideally 2+ years within a technology startup or scale-up
- Experience working in smaller engineering teams where you've had genuine ownership
- Strong understanding of backend architecture, APIs, databases and distributed systems
- Ability to discuss technical decisions, architecture and trade-offs in depth
- Comfortable taking a problem from initial requirements through design, development, testing and production
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 will make you stand out
We're particularly interested in engineers who can demonstrate examples of:
- Designing backend services or systems from scratch
- Making and defending architectural decisions
- Solving scalability, reliability or performance problems
- Working with microservices and event-driven architectures
- Taking ownership of business-critical product features
- Working directly with product teams, founders or senior stakeholders
- Seeing a startup product evolve and scale over several years

The opportunity
You'll join a product-focused technology business where engineering has a significant influence over the direction of the product.
This isn't a role where you'll simply be handed tickets to complete. You'll be expected to understand the problem, contribute to the solution and be able to explain why you've chosen a particular technical approach.
The company is open to strong mid-level or senior engineers, with a salary of up to £100,000 plus share options.
The role requires 1 day per week in London.
Please note: the company cannot provide visa sponsorship, so applicants must already have the unrestricted right to work in the UK.
If you're currently building backend systems with Java, Kotlin and Spring Boot, have meaningful startup/scale-up experience, and enjoy getting into the technical detail of what you're building, I'd be keen to speak with you.
