Senior Backend Engineer, Java

Senior • Remote

22,000 - 26,500 PLN/yr

Berlin, BE, Germany

We're hiring senior backend engineers with deep Java experience.

We're filling three seats: two Senior Java Developer roles and one role for an engineer with strong Camunda experience. If BPMN and process orchestration are your strengths, this role is especially relevant.

What you'll do

  • Design, build, and maintain backend services in modern Java (17+); the current case is a JVM backend with room to shape its architecture.
  • Make senior-level decisions on API design, data modeling, concurrency, performance, and trade-offs.
  • Collaborate directly with clients and teammates, from feature discussions through deployment.
  • Review pull requests, provide feedback, and help keep the codebase elegant and reliable.
  • Contribute ideas beyond assigned tickets.

What we value

  • 8+ years of backend Java experience and fluency with the modern JVM ecosystem, including Spring Boot or similar, build tooling, and testing.
  • Depth in concurrency, correctness under load, and API design.
  • Pragmatic use of design patterns.
  • For one opening: hands-on Camunda 7 or 8 experience, including BPMN modeling, workers, and process versioning.
  • Ability to work independently and asynchronously in a remote setup.
  • Consistent progress reporting through pull requests, recorded screenshare demos, and up-to-date project boards.
  • Ability to use AI/LLMs to improve delivery.
  • Optional: interest in occasionally contributing to TypeScript/React work.
  • Curiosity, humility, and kindness.

Benefits

  • 100% remote work with no offices or micromanagement.
  • Annual in-person meet-up with company-paid travel, hotel, and dinners.
  • A culture focused on autonomy, craft, and learning, with minimal managerial layers.

Process

  • Short introductory call.
  • Small, reasonable, realistic take-home coding challenge.
  • 90-minute conversation to discuss your work and the role.
  • Offer, if there is a mutual match.
