Job Description

Senior Backend Engineer (Java)

Location: UK (Hybrid – 1–2 days per week, Welwyn Garden City)
 Permanent Role

We are looking for a Senior Java Engineer to join a fast‑growing technology organisation that is redefining how modern software platforms are built and operated. This is an opportunity to work on scalable, backend systems that underpin data‑driven, event‑based products used by customers at scale.

If you are passionate about building high‑quality backend services, enjoy taking ownership of systems in production, and want to work in a DevOps‑led environment, this role offers both technical challenge and long‑term growth.

The role

As a Senior Backend Engineer, you’ll be responsible for designing, developing, and owning backend services built primarily in Java (Spring Boot). You’ll work across the full lifecycle — from system design and development through deployment, monitoring, and ongoing optimisation in production.

The environment follows DevOps principles, meaning engineers take responsibility for the reliability, performance, and maintainability of the services they build. You’ll collaborate closely with other engineers, platform teams, and product stakeholders to ensure systems are robust, scalable, and well documented.

The platforms are event‑driven and data‑intensive, supporting real‑time processing and integrations across distributed services. You’ll be encouraged to propose improvements, influence engineering standards, and help evolve both systems and ways of working.

What you’ll be doing

Designing and developing high‑quality Java backend services, primarily using Spring Boot
Building and operating event‑driven, microservices‑based architectures
Taking ownership of services in production, including deployment, monitoring, and support
Applying CI/CD best practices to enable reliable and frequent delivery
Working with cloud infrastructure, primarily on Microsoft Azure
Using Infrastructure as Code (e.g. Terraform) or developing the capability to do so
Producing clear technical documentation to support system design and ongoing development
Collaborating with engineers, platform teams, and stakeholders to deliver scalable solutions

What we’re looking for

Several years of experience delivering backend services in Java in production environments
Strong hands‑on experience with Spring Boot and modern Java development practices
A solid understanding of distributed systems, scalability, and reliability
Experience working in a DevOps‑led environment, with ownership of live systems
Familiarity with cloud platforms (Azure preferred, others acceptable)
Exposure to CI/CD tooling such as GitHub Actions or similar
Experience working with SQL and NoSQL databases
Strong problem‑solving skills and the confidence to take ownership of technical decisions
Nice to have (but not required):

Experience with Python in backend, data, or automation contexts
Exposure to AI/ML or large language model‑based systems
Kubernetes and container orchestration experience

Tech environment

Languages: Java (primary), other JVM languages welcome; Python a plus
Frameworks: Spring Boot
Architecture: Microservices, event‑driven systems
Cloud: Microsoft Azure
Infrastructure: Terraform (IaC)
Databases: PostgreSQL and NoSQL solutions
CI/CD: GitHub Actions
Monitoring & alerting: New Relic, Splunk, xMatters (or similar)
Tools: GitHub, Jira, Zendesk

Why join

Join an organisation experiencing triple‑digit growth
Work in a multicultural, highly skilled engineering team
Genuine ownership of systems, not just feature delivery
Opportunities to upskill in DevOps, cloud, and platform engineering
Competitive compensation and benefits, including medical insurance
