<p style="min-height:1.5em"><strong>Join BLP and help make the world’s business processes autonomous! </strong></p><p style="min-height:1.5em">Our agentic platform helps finance and operations teams worldwide remove manual work from their core business processes, so work runs end-to-end with greater control and significant productivity gains. </p><p style="min-height:1.5em">Today, over 550 enterprise customers use BLP across 1,300+ deployed projects. In the processes we automate, customers achieve productivity improvements of 5 to 10 times. </p><p style="min-height:1.5em">To date, BLP remains majority employee-owned, with Goldman Sachs holding a minority stake as a growth investor. Our success is driven by deep expertise in technology and business processes, a superior product with strong product-market fit, reflected in an expanding customer base that includes Fortune 500 companies. </p><p style="min-height:1.5em">BLP is one of Switzerland's fastest-growing SaaS scale-ups; we are now entering our next phase of growth.

The Platform Team owns what all of them are built on: shared services and APIs, the data access layer, and the component and design system that shape how the product looks and behaves.</p><p style="min-height:1.5em">The team's focus has been the frontend platform, and we are now deliberately extending that ownership deeper into the stack. You would be central to that shift, with real influence over how the platform layer gets defined rather than inheriting someone else's blueprint.</p><div style="min-height:1.2em;margin-top:0px;margin-bottom:0px"> </div><h2>About the role</h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>What you'll do and for whom.</strong> You build and run the core backend service our product teams rely on, from its APIs and persistence layer to email, user provisioning, and cross-tenant capabilities for large enterprises. Through those teams, your work reaches the 20'000+ people who use our Purchase-to-Pay and Order-to-Cash agents every day.</p></li><li><p style="min-height:1.5em"><strong>Where you'll work.</strong> You join the Platform Team, about 10 engineers. At BLP, platform means the core of our product, not internal infrastructure: the shared services, data access layer, and design system that every product runs on. You work closely with the senior backend engineer who owns these areas today, in a large production Go codebase with well-established patterns.</p></li><li><p style="min-height:1.5em"><strong>What success looks like.</strong> In your first year, you own one core area end-to-end, for example, user provisioning, outbound email, cross-tenant capabilities, analytics, or workflow configuration, from the Go service to the customer using it.</p></li></ul><div style="min-height:1.2em;margin-top:0px;margin-bottom:0px"> </div><h2>What you'll do</h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Build the service that product teams build on.</strong> Desig
