. Our industry-leading and award-winning agentic AI communications channels - intranet, employee app and email solutions - create engaging experiences that connect and empower employees.

Headquartered in Chemnitz, Germany and New York City, with offices in Berlin, London, Sydney, Tokyo, Prague, and Minneapolis-St.Paul, our diverse team of 550+ employees supports 1,500+ customers-reaching over 14 million employees-in transforming their employee experience.
We are proud to be a
Unicorn
company-privately valued at over $1 billion-demonstrating strong growth, innovation, and lasting impact in our industry. Together, we're shaping the future of workplace communication.

We're looking for an experienced Senior Fullstack Engineer to join a newly formed team at Staffbase that builds custom solutions - extending the functionality and capabilities of our award-winning employee communications platform to meet real customer needs. You'll own solutions from beginning to end: shaping use cases together with stakeholders, building them across the stack, and validating them with the people who use them.

You'll also help bring structure to a growing team of mid-level engineers and mentor them along the way. We're looking for empathetic, motivated team players who are driven by ownership and growth.

As part of our tech stack, we use: React.js, Type Script, JavaScript, Node.js, Kotlin, Go, Java, MongoDB, REST APIs & SDKs, Docker, Terraform, Selenium and Cypress, to name a few.

• Working with skilled and like-minded professionals in a team that values diversity and inclusivity
• We aim to create a flexible and agile work environment that promotes the well-being and work-life balance of our employees

• Own the development of custom solutions end-to-end - from technical design through implementation, testing, and release
• Partner with stakeholders (customers, consultants, and internal teams) to define and detail use cases before development, then validate solutions and gather feedback afterward
• Build across the stack: customer-facing UI in React and Type Script, backend services, and integrations with Staffbase and third-party APIs
• Mentor mid-level engineers and help bring structure, engineering standards, and good practices to a newly formed team
• Work in a cross-functional, agile setup and produce high-quality, well-tested code
• Give and receive valuable feedback in our code review process, and continuously learn and share knowledge with your peers
• Work iteratively - pushing code frequently, keeping a healthy CI/CD pipeline, and automating where it helps

• Solid professional experience (typically 5+ years) as a fullstack developer, including working within engineering teams and owning solutions from…
