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
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
Define and drive Staffbase’s extensibility strategy, designing the framework, SDK and standards that let our teams and customers build their own extensions and integrations
Build the core systems that enable our AI assistant to take action across Staffbase and connect to external providers
Lead technical strategy and architecture
Influence technical decisions and their documentation, driving long-term sustainable solutions to accommodate future growth and requirements
Continuously improve and refine our development processes, CI/CD pipeline, and automation practices to foster a productive development experience
Take ownership of major technical decisions, proactively addressing system bottlenecks and ensuring product quality
Contribute to and maintain technical roadmaps with engineering leadership to align project priorities and business goals
Manage and prioritize projects and initiatives across multiple teams
Foster a culture of ownership, technical excellence and continuous improvement within the team
Role modeling and developing others in the craft of Product Software Engineering
Mentor and guide engineers, providing leadership, feedback and fostering growth through code reviews and technical discussions
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
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
Ability to drive technical direction, including making decisions on architectural trade-offs and evaluating the long-term impact of technical choices
Previous experience working alongside Product and Design Leaders to deliver customer value in an Agile environment
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
Passion for building high-quality software
Proven track record as a Staff Engineer or Technical Lead with strong leadership and problem-solving skills
Extensive experience with Java/Kotlin or Go on the backend and React on the frontend
Strong communication skills with the ability to articulate complex technical concepts to various stakeholders, both technical and non-technical
Knowledge of architecture and design patterns
Strong problem-solving skills and ability to work collaboratively in a fast-paced, dynamic environment
Experience managing architecture projects across multiple development teams, aligned with their roadmaps and stakeholders
Deep understanding of multi-tenant architecture, with strong judgment on where to standardise versus where to stay flexible in platform design
