Responsibilities

As a Fullstack Staff Engineer on the Actions team, you'll take on one of our most important platform challenges: defining how extensibility works across Staffbase. Today, extensions power everything from HR integrations to the actions our AI assistant, Navigator, performs on a user's behalf - but there's no single, easy way to build and extend. That's what you'll design.

Your north star is a framework that our engineers, our Labs team, and eventually customers themselves can use to build their own extensions, whether that's a one-off integration for a single customer or a tier-one capability used across our entire base. You'll build the core, define the standards, and make the calls on where we standardise versus where we stay flexible, all on a mature, multi-tenant platform.

This is a role for someone who wants to drive, not just deliver, shaping the direction of a genuinely open-ended problem and setting the technical foundations others will build on.

Requirements

• Proven track record as a Staff Engineer or Technical Lead with strong leadership and problem-solving skills
• Proven experience designing and building extensibility within a B2B / enterprise platform, SDKs, plugin systems, or extension frameworks that let internal teams and external customers build on top of a core product, with the judgment to define what "good" extensibility looks like from the ground up
• Deep understanding of multi-tenant architecture, with strong judgment on where to standardise versus where to stay flexible in platform design
• Extensive experience with Java/Kotlin or Go on the backend and React on the frontend
• Knowledge of architecture and design patterns
• Strong problem-solving skills and ability to work collaboratively in a fast-paced, dynamic environment
• Ability to drive technical direction, including making decisions on architectural trade-offs and evaluating the long-term impact of technical choices
• Experience managing architecture projects across multiple development teams, aligned with their roadmaps and stakeholders
• Strong communication skills with the ability to articulate complex technical concepts to various stakeholders, both technical and non-technical
• Previous experience working alongside Product and Design Leaders to deliver customer value in an Agile environment
• Passion for building high-quality software
• Passion for diversity and inclusion, and the ability to foster a culture where the team can move forward at speed while ensuring that everyone's voice is heard and they can contribute their best

About the Company

We are enthusiastic about technology and committed to using it to improve the world. We follow the “You build it, you run it” approach and take pride in it.

The Actions team sits at the heart of Staffbase's AI ambitions. We're the team that gives Navigator - our AI assistant and the main entry point into Staffbase - the ability to actually do things: submit a form, complete a task inside an integration, or take an action on a user's behalf through the agent. If Navigator is the brain, we build the hands.

That means two big things. First, we enrich what the AI can see and act on, our plugins, our widgets and the wider Staffbase platform so the assistant can do real work, not just talk about it. Second, we build the extensions that connect to the tools people already use, like Workday, Personio, ServiceNow and Microsoft.

We're not just shipping features, though. A core part of our mission is building the extensibility framework that lets others build too.
