Senior Full Stack Engineer

We are looking for a seasoned Full Stack Engineer who is equally comfortable designing and owning complex backend systems as they are building clean, responsive user interfaces. You will work across our core product stack; Spring Boot microservices on the backend and React on the frontend and will be expected to take end-to-end ownership of features from architecture through to production. This is not a "frontend with some Java" role or vice versa, we need someone who is genuinely strong on both ends of the stack and can communicate clearly with product, design, and infrastructure peers.

Key Responsibilities

Backend Engineering

• Design, build, and maintain high-performance Spring Boot microservices in a distributed, cloud-native environment
• Own service architecture decisions, data modeling, API design, caching strategy, and inter-service communication patterns
• Write clean, well-documented Kotlin code with a strong focus on reliability and observability
• Participate in code reviews and set a high bar for engineering quality across the team
• Collaborate with infrastructure and DevOps on Kubernetes deployments, service mesh configuration, and CI/CD pipelines

• Build and maintain production-grade React applications with a focus on performance, accessibility, and UX quality
• Translate product and design specifications into polished, responsive UI components
• Manage frontend state, API integration, and error handling in a thoughtful, scalable way
• Contribute to the frontend architecture. component libraries, design system conventions, build tooling

• Take features from requirements to production, including backend API, frontend UI, testing, and monitoring
• Communicate proactively with product managers and engineers throughout the development cycle
• Mentor junior engineers and contribute to internal technical documentation and engineering standards

Experience

• 5+ years of professional software engineering experience in a backend-heavy or full stack capacity
• Deep, hands-on experience with Spring Boot. You should be able to discuss and defend choices around Spring lifecycle, dependency injection, transaction management, security filters, async processing, and performance tuning without hesitation
• Solid React experience; hooks, state management (Redux or Zustand), component design patterns, and performance optimization
• Experience with RESTful API design and ideally some exposure to GraphQL or gRPC
• Familiarity with relational databases (PostgreSQL / MySQL) and working knowledge of caching layers (Redis)
• Experience with containerized deployments. Docker and Kubernetes are part of our everyday workflow
• Exposure to event-driven architectures using Kafka or a comparable messaging system is a strong plus

• Strong written and verbal communication skills in English. You will regularly write technical proposals, participate in design discussions, and communicate progress and blockers clearly
• Comfortable working asynchronously across teams and time zones
• Able to explain technical trade-offs and decisions to non-engineering stakeholders without resorting to jargon
