Backend Engineer

Description:

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

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.
