About the role

Join BLP and help make the world’s business processes autonomous! 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. 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. 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. BLP is one of Switzerland's fastest-growing SaaS scale-ups; we are now entering our next phase of growth. From our headquarters on Zürich's Bahnhofstrasse, we're expanding globally, with a growing presence across Europe and North America. Join us and help make autonomous operations the new standard. The team At blp, dedicated engineering teams own individual products such as invoices, customer orders, and order confirmations. 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. 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.   About the role We are looking for a fullstack engineer with a strong backend center of gravity who enjoys designing reliable systems, thinking rigorously about correctness, and applying strong software fundamentals to real-world operational problems. Platform touches both client facing features as well as internal tooling. The capabilities we own are the ones our users touch most often: how workflows and dashboards are configured, how fast a screen full of exceptions loads, how consistently permissions behave, how reliably a release reaches production. When the platform is right, every product team ships better software faster, and that lands directly with the tens of thousands of people who use blp every day. Platform decisions here are judged by what they do for our users, not by internal elegance.   What you'll do • Build the Foundation: Design and develop the shared backend services and APIs that our product teams depend on, with clear contracts and abstractions that fit how they actually work. • Drive User Impact: Work with product teams and business stakeholders to understand where the platform is holding them back, communicate trade-offs openly, and turn that into concrete improvements our users feel. • Own Reliability and Correctness: Build and operate systems with a strong focus on robustness, and improve them continuously through careful analysis and iteration. Managing entropy in a complex system is part of the job, and we expect you to adapt accordingly. • Build Great Software: Write clean, maintainable, high-quality code across the stack. Conduct code reviews and contribute to a culture of technical excellence. • Shape Architecture: Collaborate on system design, tech stack decisions, and platform boundaries, optimizing for scalability, performance, and maintainability. • Lead and Influence: Guide technical direction on major initiatives such as migrations and platform capabilities, and mentor team members along the way. • Promote Innovation and Collaboration: Work closely with colleagues to continuously improve processes, tools, and team practices, fostering a culture of learning and growth.
