Blockchains do not scale to a global user-base of seven billion people.

Distributed systems research engineering at Heliax focuses on designing, building, extending, and maintaining decentralized, permissionless, and censorship-resistant protocols. We are looking for experienced distributed systems engineers that are interested in applying novel research to create high-quality open-source technology and solve outstanding problems in the blockchain space. As a member of the core protocol engineering team, you will be working on distributed ledger technology implemented in Rust, with a particular focus on distributed systems: consensus algorithms and peer-to-peer networking layers. You’ll work both on the research and implementation side to ensure that our protocols are both theoretically sound and correctly realized in code. This role offers the chance to work closely on compelling cross-disciplinary problems in computer science, systems engineering, cryptography, and economics, and enjoy a high degree of independence in working conditions and prioritization.


  • Produce technical specifications of BFT consensus algorithms and peer-to-peer systems in coordination with other team members
  • Analyze consensus protocols for safety, liveness, incentive compatibility under a rational actor model, asymptotic and concrete efficiency, and implementation difficulty
  • Implement protocols in performant and cleanly abstracted Rust code
  • Comprehensively document and test protocols and protocol changes
  • Benchmark implementations and adjust both high-level architecture and low-level details in order to optimise for performance while retaining semantic correctness
  • Conduct code reviews in coordination with other team members and help maintain a high standard of quality across the codebase


  • Prior experience with distributed systems such as BFT consensus algorithms
  • Familiarity with the Rust programming language
  • Self-motivated & self-organized
  • Interested in open-source technology and research applied to DLT

Bonus Qualifications

  • Prior experience with large scale distributed systems deployed in practice
  • Prior experience with network and systems engineering
  • Prior experience with database design and optimization
  • Prior experience in blockchain technology
  • Prior experience implementing cryptography


Remote or local (Zürich/Zug, Berlin). When remote, preferred if mostly located within (+/- 7 hours) Central European time zones. Ideally someone who enjoys nature and hiking 🏔️.
