As a Senior Backend Software Engineer, you will work as a core contributor within a high-performing engineering team, taking full technical ownership of backend systems rather than executing predefined tasks.

This role is designed for engineers who enjoy deep problem-solving, architectural responsibility, and building highly performant, data-intensive backend systems operating at scale.

Key Responsibilities :

• Design, build, and evolve high-performance backend services using modern Java (17+) and the Spring ecosystem.
• Take full ownership of complex backend codebases, driving continuous improvements in performance, scalability, and maintainability.
• Design and optimise data-intensive applications with strong requirements around consistency, concurrency, and throughput.
• Lead performance optimisation initiatives across the application, JVM, database, and infrastructure layers.
• Design and maintain RESTful APIs and distributed system components.
• Diagnose and resolve production performance bottlenecks using structured debugging and root cause analysis.
• Collaborate closely with a small, senior engineering team while maintaining a high level of autonomy.
• Contribute to architectural decisions, balancing modular monolith and microservices trade-offs.
• Promote strong engineering practices including testing, observability, and documentation.

Technical Stack & Back-end expertise :

• Java 17+, Spring Boot, Spring Data, Spring Security
• PostgreSQL with advanced SQL
• AWS (compute, networking, managed services integration)
• REST APIs and distributed systems
• Strong experience debugging and optimising production systems.
• Observability best practices (metrics, structured logging, distributed tracing).

Required Experience :

• Minimum 5 years of experience in backend engineer with strong architectural judgement.
• Strong expertise in database and performance optimisation.
• Fully autonomous contributor within a high-performing team.
• Proven ability to drive decisions around performance, scalability, and data modelling.
• Ability to clearly communicate technical decisions and trade-offs.
