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. Their work includes Anoma (an intent-centric distributed OS architecture) and Namada (a privacy-focused proof-of-stake L1 for interchain asset-agnostic privacy).
Applicants 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 zkSNARK/zkSTARK proof systems (e.g. Halo2, ProtoStar, Risc0 zkVM) for security, expressivity, and performance.
- Update, reimplement, and combine existing 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 and protocols, primarily in Rust.
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 (e.g., DKG, threshold encryption).
- Demonstrated protocol design experience (research paper, experimental project, past work, or detailed writeups).
- Experience implementing or reviewing cryptographic code, preferably in Rust.
Nice to have:
- Published papers in mathematics, theoretical computer science, 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 (risc0 zkVM), Arkworks, elliptic curves, hash functions, threshold encryption, distributed key generation (DKG)
Benefits:
- Relocation assistance to Germany (e.g., visa assistance).
- High degree of independence in working conditions; remote-first company.
