Senior Java Software Engineer

Senior / Staff Software Engineers – Java, Spring Boot & Angular

£90,000–£120,000 | Permanent | Hybrid – Warminster | Multiple Hires

I’m working with a global software product business building mission-critical platforms used across defence, government and resilience environments.

They’re continuing to grow their UK engineering team and are hiring across three areas:

Senior Backend Engineer
Senior Full Stack Engineer
Staff Engineer / Technical Lead

The common thread across all three roles is strong software engineering, modern Java and the opportunity to work on systems where security, reliability and engineering quality genuinely matter.

This isn’t an environment where engineers simply work through tickets.

They’re looking for people who want to take ownership, contribute to architecture, solve difficult technical problems and influence how software is designed and delivered.

The engineering environment The core stack includes:

Angular | TypeScript

Senior Backend Engineer

You’ll be focused predominantly on designing and building scalable backend services and integrations.

This could include Java/Spring Boot microservices, REST APIs, event-driven architecture, PostgreSQL, cloud-native deployments and solving problems around reliability, scalability and performance.

We’d particularly like to speak with engineers who have experience across Java, Spring Boot, SQL, APIs, distributed systems and cloud infrastructure.

Senior Full Stack Engineer

This role is genuinely full stack.

You’ll work across Java/Spring Boot on the backend and Angular/TypeScript on the frontend, taking ownership of features from system design through to production.

Strong experience with Java, Spring Boot, Angular, TypeScript, REST APIs and SQL would be ideal.

Staff Engineer / Technical Lead

This is for someone who wants broader technical influence without moving away from engineering.

You’ll help shape architecture and engineering standards across teams, mentor experienced engineers, review technical designs and solve difficult system-level problems while remaining close to the code.

We’re particularly interested in people currently operating as a:

Staff Engineer | Principal Engineer | Technical Lead | Lead Software Engineer | Hands-on Architect

You’ll likely have strong experience with Java/Spring, distributed systems, cloud architecture, event-driven platforms and technical leadership across multiple teams.

What we’re generally looking for

Strong experience in several of the following:

Java / Spring Boot / Microservices / REST APIs / PostgreSQL / Kafka / RabbitMQ / AWS / Azure / Kubernetes / Docker / Angular / TypeScript / CI/CD / automated testing

Experience across defence, government, aerospace, financial services, critical infrastructure or other regulated environments would be particularly useful.

Most importantly, they’re looking for engineers who can explain why they make technical decisions rather than simply which technologies they have used.

The opportunity

These are permanent positions working on software with genuine real-world importance.

There is strong scope to influence architecture, engineering practices and technical direction as the organisation continues to grow.

Salary: circa £90,000–£120,000 depending on level and experience

Location: Hybrid around Warminster

Employment: Permanent

Clearance: Candidates will need to be eligible to obtain UK SC clearance

Whether you’re a strong Senior Engineer looking for your next technical challenge or an established Staff/Lead Engineer wanting wider architectural influence while remaining hands-on, I’d be interested in speaking with you.

Apply directly or message me confidentially and I can talk you through the different opportunities.
