Research Cryptographer & Mathematician
Full-time/Company: Heliax
Heliax is a remote-first company researching, developing, and maintaining open-source protocols and products such as Anoma and Namada. Learn more: heliax.dev
Candidates must be based in Europe (including the UK) and willing to travel to Berlin for initial onboarding.
Responsibilities:
- Design new cryptographic protocols (e.g. shielded state sync) to meet specified information flow, security, and performance goals.
- Evaluate and analyze existing cryptographic protocols, often zkSNARK or zkSTARK proof systems (e.g. Halo2, ProtoStar, Risc0 zkVM).
- Update, alter, reimplement, and combine protocols for proofs-of-concept and production use-cases.
- Produce comprehensive technical specifications for protocol designs and collaborate with engineers on implementations.
- Implement, review, and test cryptographic operations and protocols, primarily in Rust.
Requirements:
- Strong mathematical and/or cryptographic background (complexity theory, abstract algebra, protocol design).
- Expertise in constructive protocol design and analysis of distributed cryptographic protocols.
- Demonstrated protocol work (research paper, experimental project, past work, or detailed write-up).
- Experience implementing or reviewing cryptographic code, preferably in Rust.
Nice to have:
- Published papers in mathematics, theoretical CS, or cryptography.
- Experience with distributed systems and/or 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, distributed key generation, threshold encryption
Benefits:
- Relocation assistance to Germany (visa assistance) for candidates as needed.
- Remote-first company culture with a high degree of independence and cross-disciplinary collaboration.
