What we're looking for

Modelling logic and correctness by construction is paramount to us. We aim to express what must be true, prevent invalid states, and keep systems pristine even as they grow.

Thus, we're looking for highly ambitious engineers who can tackle difficult problems and think precisely. You must be able to make assumptions explicit and use formal, structured reasoning to reach a solution, and explain why it is correct. Typically, strong background in mathematics is a key foundation for this kind of work. We also place a high value on thoroughness and perfectionism.

Tooling wise, we rely heavily on type systems & functional programming.

Nice to have

We do not require experience with any particular technology or even industry software development experience.

You should, however, provide clear evidence of the abilities we're looking for. That evidence could include:

strong academic backgrounds (math PhD/MSc or significant olympiad achievements)
startup experience (early employee, built productive systems yourself & know what it takes to maintain them)
FP experience (have deep understanding of programming languages and are able to discern the various tradeoffs of different paradigms)

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.

Delta builds BLP's core software: the technical foundation that everything else at the company runs on.

What you'll do

Our work spans four areas, you will usually work on a given project within one of:

Infrastructure: Build and operate the cloud infrastructure BLP depends on, covering security, observability and CI/CD.
Backend: Develop a large codebase, tackling performance, concurrency and the challenges of distributed systems.
ML: Apply the latest AI technology to complex, real-world business problems and turn it into reliable production software.
Unbound: Build our product extension platform, enabling BLP to automate arbitrary customer business processes as we scale.

What we value

We value engineers who think deeply about systems, care about correctness, and take pride in building infrastructure that is understandable, maintainable, and reliable.

Flexibility. Work on-site in Zurich or remotely within Europe.
