Senior Fullstack Engineer Job in Berlin | Staffbase

Staffbase has a Senior Fullstack Engineer opening in Berlin for an experienced developer who can take custom product extensions from an early use case through release. The position sits in a newly formed engineering team focused on work that adapts the Staffbase employee communications platform to specific enterprise customer needs.

The work spans customer-facing interfaces, backend services and integrations rather than a narrow single-layer remit. It suits a developer who combines practical delivery ownership with the ability to turn conversations with customers, consultants and internal colleagues into maintainable technical solutions, then listen to feedback once those solutions are in use.

Opportunity Details

A full-stack remit shaped around customer extensions

Berlin-based engineering for configurable enterprise use cases

This Berlin vacancy concerns a senior engineering contribution to custom solutions that extend the Staffbase platform. The team builds widgets, plugins and integrations intended to make the product work for customer-specific requirements. That focus gives the role a clear product context: understand a use case, decide how it should work technically, implement it across the stack, test it and help bring it into release.

The posting describes a newly formed team, so the role includes more than individual feature delivery. The successful engineer is expected to help establish useful engineering standards, add structure to team processes and support mid-level colleagues. The practical emphasis is on reliable, scalable extensions rather than isolated prototypes.

Berlin is one of the locations listed for this position. The employer states that a hybrid work option is available, while the vacancy does not set out a schedule. Candidates should therefore treat the job description as the source for technical scope and use the official application process for any role-specific working arrangement details.

About the Employer: Staffbase

Employee communication and experience platform context

Connecting communication, knowledge and action across workforces

Staffbase describes its purpose as ensuring that employees are not left behind when access to information, tools and AI is uneven across an organization. Its employee experience platform connects communications, human resources and information technology to deliver personalized experiences through multiple channels. The company presents the platform as a way to give employees a trusted place to participate, find relevant information and understand what comes next in their work.

The platform includes intranet, employee app and email solutions. Staffbase says its multichannel approach delivers communications and knowledge through the channels employees already use, including for frontline, deskless and office-based workforces. This is relevant to the advertised role because the team extends an existing communications platform with customer-specific widgets, plugins and integrations.

Official company material describes Staffbase as an AI-native employee experience platform. It also explains that the platform is designed to work with digital workplace tools and enterprise human resources systems, connecting communications, knowledge and action across those systems rather than replacing existing investments. That integration-oriented context aligns with a role that works with external systems, APIs and software development kits.

Platform integration and governed AI context

A product setting relevant to custom solutions engineering

For security-sensitive settings, Staffbase states that it protects organizational data across its lifecycle with enterprise-grade infrastructure, granular controls and governed AI experiences. The company also describes an AI Quality Layer that checks answers for relevance, context and organizational alignment before they reach employees. These published product themes provide useful context for engineers building extensions intended for enterprise customers.

Staffbase identifies Berlin among its office locations and describes a work setting that values diversity, inclusivity, technology and a build-and-run approach. The vacancy itself places the engineer in a cross-functional, agile setup where code quality, testing, review and knowledge sharing are part of everyday delivery.

Open Positions

Application Guidance

Show end-to-end engineering evidence

Prepare examples that connect use cases, architecture and delivery

For a senior full-stack post, the clearest evidence is work you owned from first design through to production. Select concise examples in which you moved from an incomplete business need to a technical design, implementation, testing and release. Explain the frontend and backend choices, the integration boundaries and the signals that showed whether the result met the intended use case. Where customer or internal feedback changed the solution, describe the adjustment clearly.

Because the team is forming its practices as well as its solutions, prepare examples of constructive mentoring, code review and engineering standard-setting. Candidates can also be ready to discuss how they have maintained quality while delivering iteratively, including test coverage, automation and reliable continuous integration and delivery. Keep language claims precise, as fluent English and German are stated requirements for this role.

• Choose a project example that demonstrates React and TypeScript work connected to a backend service or integration.
• Outline how you converted stakeholder needs into specific acceptance points and later gathered user feedback.
• Prepare a brief explanation of your experience with REST APIs, software development kits and external systems.
• Identify one mentoring or guidance example that shows how you supported a less-experienced developer.
• Bring evidence of testing, code review and continuous delivery practices that protected quality during iterative work.
• Review your English and German language information so it accurately reflects the fluency required by the vacancy.
