Your role in the team
- You design and ship backend Java services that thousands of customers depend on every day.
- You own customer-facing distributed systems end to end, from understanding the real problem behind a request to running the fix in production.
- You bring engineering judgment into every conversation with Product Owners and stakeholders, shaping the solution instead of just executing it.
- You design and build the services, features, and tooling that power our platform, from microservices to APIs to the tools your own team relies on.
- You build it, you run it, you own it: full end-to-end responsibility, including on-call, for building, testing, deploying, and monitoring your service.
- You work agent-first by default: implementation runs through agents, judgment and ownership stay with you.
Our expectations of you
Qualifications
- Familiarity with Go is beneficial.
- You have worked with PostgreSQL, JPA/Hibernate, Flyway, Redis, and Kafka, and understand how to choose the right persistence and messaging pattern for the problem.
- You are comfortable owning services in production, improving them through observability, metrics, alerting, CI/CD, and Kubernetes-based operations.
- You run agentic workflows end to end: orchestrating agents, judging their output, and tuning the eval loops that keep quality high without reviewing every line yourself.
- You're genuinely curious about the customer's problem, not just the code.
- You move comfortably across the stack, translate technical trade-offs into plain business language, and treat a great product conversation as seriously as a great pull request.
Experience
- You have development experience in Java, and Spring Boot is a must.
- You are experienced in microservices and event-driven architectures, and know how to design for reliability, scalability, idempotency, and long-term maintainability.
What we offer
