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 operating system architecture) and Namada (a proof-of-stake L1 focused on interchain 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 information flow, security, and performance goals.
- Evaluate and analyze proof systems (zkSNARKs/zkSTARKs) and implementations (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 and collaborate with engineers on protocol implementations.
- Implement, review, and test cryptographic operations and protocols, primarily in Rust.
Requirements:
- Mathematical and/or cryptographic background in relevant subfields (e.g. complexity theory, abstract algebra, protocol design).
- Expertise (formal or informal) in constructive protocol design and analysis of distributed cryptographic protocols.
- Demonstrable protocol design experience (research paper, experimental project, past work, or detailed technical write-up).
Nice to have:
- Published papers in mathematics, theoretical computer science, and/or cryptography.
- Experience with distributed systems and/or operating systems architecture/design.
- Experience with Zerocash/Zexe/VeriZexe and related architectures.
- Academic qualifications in a relevant field (cryptography or mathematics).
Stack:
Rust, zkSNARKs, zkSTARKs, Halo2, ProtoStar, Risc0 zkVM, Arkworks
Benefits:
- Relocation assistance to Germany (e.g. visa assistance).
- Remote-first role with a high degree of independence in working conditions and task prioritization.
- Opportunity to work on open-source protocols and cross-disciplinary research.
