Research Cryptographer & Mathematician
Full-time/Company: Heliax
Heliax is a remote-first company that researches, develops, deploys, and maintains open-source protocols and mechanisms to serve everyday needs. The team builds vertically integrated open-source products and networks, including the Anoma intent-centric architecture and Namada, a privacy-focused proof-of-stake L1.
Applicants must be based in Europe (including the UK) and be willing to travel to Berlin for initial onboarding.
Responsibilities:
- Design new cryptographic protocols to meet specified information-flow, security, and performance goals.
- Evaluate and analyze existing zkSNARK/zkSTARK and related proof systems for security, expressivity, and performance.
- Update, reimplement, and combine cryptographic protocols for proofs-of-concept and production use-cases.
- Produce comprehensive technical specifications and collaborate with engineers on implementations.
- Implement, review, and test cryptographic operations and protocols, primarily in Rust.
- Contribute to open-source cryptography projects and tooling.
Requirements:
- Strong mathematical and/or cryptographic background (e.g. complexity theory, abstract algebra, protocol design).
- Proven experience in constructive protocol design and analysis of distributed cryptographic protocols (research paper, project, or detailed system).
- Experience implementing cryptographic protocols, preferably in Rust.
Nice to have:
- Published papers in mathematics, theoretical CS, or cryptography.
- Experience with distributed systems and operating-systems architecture/design.
- Experience with Zerocash/Zexe/VeriZexe and related architectures.
- Academic qualifications in cryptography or mathematics.
Stack:
Rust, zkSNARKs, zkSTARKs, Halo2, ProtoStar, Risc0 zkVM, Arkworks, elliptic curves, threshold cryptography
Benefits:
- Remote-first company with a small, cross-disciplinary team and freedom in task prioritization.
- Relocation assistance to Germany (including visa help) for candidates willing to relocate.
- Opportunity to work on publishable research and open-source projects.
