You'll create the UI components, integration layers, and security mechanisms that enable our customers to extend the platform with custom integrations while maintaining safety and flexibility across our 1,500+ customer base. This is essential infrastructure work that shapes how our customers scale their integrations.</span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;"><strong>Our environment</strong></span></p> <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 14pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">Working with skilled and like-minded professionals in a team that values diversity and inclusivity</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 14pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">We aim to create a flexible and agile work environment that promotes the well-being and work-life balance of our employees</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 14pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">We believe that team events during working hours play a vital role in building an exceptionally effective team, and we encourage them</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 14pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">We are enthusiastic about technology and committed to using it to improve the world</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 14pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">We follow the “You build it, you run it” approach and take pride in it</span></li> </ul> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;"><strong>The Team</strong></span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">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.</span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">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. </span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;"><strong>What you'll be doing</strong></span></p> <ul> <li style="font-family: arial, helvetica, sans-serif;
