Research Cryptographer & Mathematician
Employment type: Full-time/Company: Heliax
Heliax is a remote-first company that researches, develops, deploys, and maintains open-source protocols and mechanisms, building vertically integrated open-source products and networks such as Anoma and Namada.
Applicants must be based in Europe (including the UK) and be willing to travel to Berlin for initial onboarding.
Responsibilities:
- Design new cryptographic protocols (e.g. shielded state sync) to achieve specified information flow, security, and performance goals.
- Evaluate and analyze existing cryptographic protocols (zkSNARKs, zkSTARKs, etc.) for security, expressivity, and performance.
- Update, reimplement, and combine cryptographic 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 & protocols, primarily in Rust.
- Contribute to research and example projects such as Anoma resource machine in RISC0 and threshold decryption protocols.
Requirements:
- Strong mathematical and/or cryptographic background (e.g. complexity theory, abstract algebra, protocol design).
- Expertise in constructive protocol design and analysis of distributed cryptographic protocols.
- Demonstrated protocol design experience (research paper, experimental project, past work, or detailed technical write-ups).
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, Risc0 zkVM, Arkworks, DKG, threshold encryption, elliptic curves
Benefits:
- Relocation assistance to Germany (including visa help).
