We are seeking a Senior Java Engineer with deep, long-term experience designing, building, and maintaining complex backend systems. This role is fundamentally Java-led, focused on high-quality service design, integration, data processing, and long-lived enterprise platforms.
You will work primarily on Java-based systems using modern frameworks and architectural patterns, with cloud platforms (notably AWS) used as an execution environment rather than the defining skillset. The role suits an engineer who understands systems holistically — from business requirements and data integrity through to production reliability.
We offer hybrid working, with occasional presence at one of our Holland & Barrett offices in London or Nuneaton to attend team meetings, collaboration sessions and key events.
Key Responsibilities- Design, develop, and maintain robust Java applications and services
- Build and evolve service-oriented and microservice architectures using Java and the Spring ecosystem
- Take ownership of business-critical backend systems, including migrations, integrations, and refactoring of legacy platforms
- Ensure data correctness, transactional integrity, and system reliability
- Design and implement REST-based APIs and asynchronous integrations
- Participate in architectural discussions and technical decision-making
- Support production systems, diagnose issues, and implement durable fixes
- Collaborate closely with stakeholders to translate business processes into technical solutions
- Mentor other engineers and promote strong engineering standards
- Core Java & Backend
- Extensive commercial Java experience (10+ years) in large-scale systems
- Strong knowledge of modern Java (8–17+) and JVM fundamentals
- Deep experience with the Spring ecosystem, including: Spring Boot, Spring MVC / WebFlux, Spring Security, Spring Batch
- Strong understanding of object-oriented design, integration patterns, and service boundaries
- Proven experience designing and consuming REST APIs
- Strong SQL and database experience (relational and/or NoSQL)
- Experience working with event-driven or message-based systems
- Solid automated testing practices (unit, integration, BDD/TDD where appropriate)
- Full SDLC experience: design, development, release, and production support
- Comfortable working in complex, legacy-adjacent environments
- Experience in regulated or data-sensitive domains is a strong advantage
- Clear communicator, able to work effectively with technical and non-technical stakeholders
- Experience deploying Java applications on AWS, including: EC2, ECS/Fargate, Lambda, SNS, SQS, DynamoDB or RDS
- Exposure to cloud-native or event-driven architectures
- Kotlin or JVM-adjacent languages
- E-commerce or high-transaction platforms
(AWS experience is considered an advantage, not a prerequisite. Strong Java engineers without deep cloud backgrounds are encouraged.)
Benefits- Health Cash Plan
- Life Assurance
- Incentive Scheme - Based on company & personal performance
- Virtual GP
- Private Medical care
- Holiday Purchase option
- Access to ‘Wellhub' with gyms, studios and wellbeing apps
- Discounts & Savings
- 25% Colleague Discount with FREE Standard Delivery
- Exclusive Discounts from a wide range of partners
- £/€50 Annual Product Allowance to spend in store
- Learning & Development
