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.</span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">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.</span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">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.<br></span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">As part of our tech stack, we are using: React.js, JavaScript, TypeScript, Tailwind CSS, Kotlin, Go, Java, MongoDB, Terraform, Docker and Playwright, to name a few.<br></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;"&
