Gapfruit builds the operating system for environments where security, safety, and privacy matter. We bring recognized academic systems research to real-world products.

Gapfruit answers the following question:
How can we prove the trustworthiness of a product?

Gapfruit OS is a microkernel operating system with capability-based security. We offer unprecedented customizable Trusted Execution Environments for the high-end banking sector with an easy-to-use API. Gapfruit TEE proves that a certain output was generated from a specific input, executed at a specific time with specific code.

Gapfruit is expanding its technology to the IoT/EDGE market, and ultimately to anywhere a resilient operating system is needed. Gapfruit is seeking engineers at nearly every level of the software stack. From firmware to device drivers, protocol stacks, microkernels, hypervisors, higher-level management software, and integration with cloud environments.

You have an affinity for designing computer systems that matter. You most likely have done work in C/C++ on Linux, the Genode Framework, or real-time operating systems. You know your way around Git and CI/CD environments. You have a desire to go deep into gnarly systems problems. While you love playing with new technologies, you are comfortable taking ownership of robust feature design and implementation. You long for a team with open and inclusive ideals. You enjoy working with and contributing to open source communities. You appreciate diversity and nurture a culture of openness and collaboration. You understand the discrepancy between security and safety-critical systems. You may even have developed safety/mission-critical software using ADA/SPARK and done formal verification. You know the concepts of PKI and capability-based security. You see the value of modern package management systems such as Nix or Guix. You are interested in trusted computing concepts and dealing with TPM's.

The nature of the problems we're solving favors candidates with experience. However, we are open to entry-level engineers who feel motivated to be a part of building the next generation of trustworthy systems. While we prefer on-site in Zug, Switzerland, we also support remote work.

Gapfruit is a well-funded, early-stage deep tech company established in 2018.
