Your role in the team
- You design, build, and evolve reliable and scalable backend services in modern Java and Spring Boot across multiple product areas and shared platform capabilities.
- You stay hands-on in code, lead cross-team technical initiatives, and drive topics from idea to production with clear business impact.
- You work across REST and gRPC APIs, event-driven flows, PostgreSQL, Redis, Kafka, Flyway, and shared platform libraries to deliver robust customer-facing solutions.
- You raise the bar on architecture, observability, performance, security, testing, and developer experience in a cloud-native environment with Kubernetes, CI/CD, and modern engineering guardrails.
- You collaborate closely with product managers and cross-functional team members across backend, web, and mobile, and you mentor engineers through strong technical leadership, reviews, and knowledge sharing.
- You use AI-assisted tooling pragmatically where it improves quality, speed, or developer experience, and you help define sensible engineering practices around it.
Our expectations of you
Qualifications
- You have worked with PostgreSQL, JPA/Hibernate, Flyway, Redis, and Kafka, and understand how to choose the right persistence and messaging patterns for the problem.
- You are comfortable owning services in production environments and improving them through observability, metrics, alerting, CI/CD, and Kubernetes-based operations.
- You are comfortable using AI-assisted tools thoughtfully and know how to apply them in ways that remain reviewable, reliable, and useful in day-to-day engineering work.
Experience
- You have deep experience building backend services with modern Java and Spring Boot, and you are comfortable operating at Staff level across architecture, implementation, and cross-team technical leadership.
- You are experienced in microservices and event-driven architectures, and you know how to design for reliability, scalability, idempotency, and long-term maintainability.
- You are collaborative and product-minded, willing to work across the stack when needed; experience with React, TypeScript, micro-frontends, and end-to-end feature delivery is a huge plus.
