ZK Podcast

Heliax is looking for a cryptographer & researcher interested in zero-knowledge cryptographic protocols and their application to distributed ledger technology to work with us to design, evaluate, and implement zero-knowledge proof constructions such as zkSNARKs and zkSTARKs, distributed cryptographic protocols such as threshold encryption and distributed key generation, and cryptographic primitives such as elliptic curves and hash functions, then put this cryptography into practice in order to realise privacy and scalability capabilities required by the next generation of blockchain networks.

This role offers the chance to work closely with a small team on compelling cross-disciplinary problems in theoretical computer science, cryptography, game theory, economics, and systems design, and enjoy a high degree of independence in working conditions and task prioritization.

Responsibilities
- Evaluate and analyze existing zkSNARK and zkSTARK proof systems such as Groth '16, Ben-Sasson '18, and PLONK for security, expressivity, and performance; monitor the state of the research field for compelling new theoretical advances
- Update & alter existing cryptographic protocols, customize them for specific proof-of-concept and production use-cases
- Produce technical specifications for designs & instantiations of cryptographic protocols and assist with implementation in coordination with team members
- Implement, review, and test cryptographic operations & protocols, primarily in Rust, evaluate existing implementations

Example projects
- The Multi-Asset Shielded Pool (to be published soon)
- PLONK & plookup (in progress)
- The PLONK by hand series
- The Demystification series (Supersonic, Fractal)

Qualifications

- Prior experience with cryptographic protocols, especially zkSNARKS or zkSTARKs (though not specifically required)
- Prior experience in low-level systems programming, ideally in Rust
- Self-motivated & self-organized

Bonus Qualifications
- Academic research background in mathematics, computer science, economics, and/or game theory
- Prior experience with distributed ledger (blockchain) technology
- Experience in a functional programming language such as Haskell or Ocaml
- Experience with a proof assistance such as Idris, Coq, or Agda||

Misc
- Remote or local (Zürich/Zug, Berlin). When remote, preferred if mostly located within (+/- 7 hours) Central European time zones. North America is fine.
- Ideally someone who enjoys travel, nature and hiking. Often we find that protocols are best designed not in a meeting room but rather on a trail 

We are looking to hire an events coordinator, with a proven track record hosting events on and offline, for the Zero Knowledge Podcast. 

Requirements: 
* You have organised or hosted events in the past
* At least 1 year working experience in a start-up context

Nice to haves: 
* Knowledge of Blockchain & the decentralised space
* Writing and production skills

O(1) Labs is a blockchain technology company that successfully incubated the Mina Protocol. We’re currently working to develop our Zk-Snark based smart contracts (Snapps). Snapps are a new paradigm for blockchain smart contracts, using efficient zero knowledge proofs, off-chain state, & off-chain execution with a layer-1 blockchain. They bring immense opportunities for creating a very unique, powerful blockchain. 

The role
We’re looking for a software engineer to join our Snapps product team to help build various JavaScript & TypeScript apps, tools, examples, partner integrations, & similar. You won’t be working alone--our Snapps team has a technical PM (who is a JS dev) and multiple experienced JS/TS software engineers. We’re looking to expand our team to move more quickly.

Required skills
- JavaScript
- TypeScript
- React
- NodeJS

Ideal candidate
- 3+ yrs experience
- CS degree is not required
- Self-motivated & self-directed
- Front-end (React) and backend (NodeJS) experience
- Serverless JavaScript experience (nice to have, but not required)

Experience with cryptocurrency is not needed for this role; we have many, experienced crypto veterans who can help with any such aspects. But a passion for cryptocurrency &/or JavaScript would be ideal. We love what we do and hope you will too! 

Please send a resume & Github link.

We are committed to building a diverse, inclusive company. People of color, LGBTQ individuals, women, and people with disabilities are strongly encouraged to apply.
