Headquartered in Chemnitz with offices in Berlin, London, Sydney, Tokyo, Prague, and Minneapolis–St. Paul.
You'll join a newly formed team building custom solutions that extend the Staffbase platform for enterprise customers. This role combines full-stack engineering with customer partnership and team leadership. You'll own solutions end-to-end: shaping use cases with stakeholders, building across the stack (React/TypeScript frontend, backend services, third-party integrations), validating with users, and mentoring mid-level engineers as the team grows.
Key responsibilities include:
- Own custom solution development from technical design through implementation, testing, and release
- Partner with customers, consultants, and internal teams to define use cases and validate solutions
- Build full-stack: React.js and TypeScript UI, backend services (Kotlin, Java, Node.js), REST APIs and third-party integrations
- Mentor mid-level engineers and establish engineering standards and practices for the new team
- Work in cross-functional, agile teams producing high-quality, well-tested code
- Participate in code reviews, share knowledge, and work iteratively with frequent deployments and healthy CI/CD
Tech stack includes React.js, TypeScript, JavaScript, Node.js, Kotlin, Go, Java, MongoDB, REST APIs & SDKs, Docker, Terraform, Selenium, and Cypress.
REQUIREMENTS:
- 5+ years professional experience as a fullstack developer, including team environments and owning solutions from concept to delivery
- Strong frontend skills: React.js, TypeScript, JavaScript
- Solid backend experience: Kotlin, Java, or Node.js
- Confidence with REST APIs, SDKs, and external system integrations
- Experience mentoring or guiding less-experienced developers and bringing structure to team processes
- Ability to work directly with stakeholders, translating business needs into technical solutions
- Strong focus on quality, clean code, testing, and continuous learning
- Fluent written and spoken English and German (both required for stakeholder and customer collaboration)
- Self-starter who works well independently and as part of a team
- Appreciation for diversity and inclusivity in the workplace
NICE TO HAVE:
- Experience with Go, MongoDB, Docker, Kubernetes, GitHub Actions, Terraform, Prometheus, or Grafana
- Background in professional services, consulting, or building custom customer-facing solutions
- Enterprise integration knowledge: SSO, SAML, OIDC, SCIM
- Understanding of REST and microservices architecture
