Head of Product

O1Labs

We are looking for an experienced and visionary Head of Product to lead O(1) Labs’ product team and be a major stakeholder in executing our go-to-market strategy. As the Head of Product, you will be a key member of the executive team, will report to the company’s CEO, and will mentor a team of PM leaders, while iterating on the company’s GTM strategy and product market fit. The ideal candidate has a vision for the direction of Web3, has product leadership experience, and is great at people management.

Responsibilities

-This role will have two primary responsibilities
1. Coach and mentor a team of product managers to effectively prioritize, work cross functionally and deliver results.
2. Collaborate with the CEO to build a long term product strategy that delivers on the vision of a private and secure Web3.

Define, communicate, and execute the product roadmap and priorities internally and externally with the broader Mina ecosystem. Craft a long term strategy for the product organization, and lead recruiting and growing the team with excellent product managers. Be a partner to the engineering organization by providing them with the leverage and focus they need to make maximum impact.

Requirements
- At least 3 years experience in leading a product organization.
- At least 5 years of product management experience.
- Hands-on experience in or exposure to the Web3 industry; enough to come in with a vision for how O(1) Labs and its technology can bring fundamental value.
- Experience working in an early-stage environment (either company or product) to find product-market fit.
- Demonstrate excellent communication, analytical and interpersonal skills.
- Working schedule with at least 6 hours overlap with US time zones.

Ideal Candidate
- Has a technical background or deep understanding of blockchain technology.
- Has experience working directly with developers.
- Has experience at organizations that build developer tooling, or generally build for developers.

With all the above said, there are no hard requirements and we're more interested in learning about your individual background. We are committed to building a diverse, inclusive company. People of color, LGBTQ individuals, women, and people with disabilities are strongly encouraged to apply.

Zero-Knowledge Cryptographer & Protocol Developer

Heliax (Anoma)

The primary project of Heliax is the Anoma protocol (implemented in Rust). Anoma is self-contained, self-sovereign and capture resistant, enabling private, asset-agnostic cash and private coordination among any number of parties. In addition to Anoma, Heliax works on open-source projects which are part of the Anoma ecosystem, including but not limited to research in cryptographic libraries such as the MASP, Plonk or Ferveo (written in Rust), and tools for high assurance validity predicates and arbitrary zero-knowledge circuits (Juvix, written in Haskell).

Heliax is a remote-first public goods lab which researches, develops, deploys, and maintains open-source protocols & mechanisms designed to serve the everyday needs of humanity. Using this, we build vertically integrated open-source products and networks that form coherent open systems which are capable of acting as an alternative to existing exploitative paradigms. With team members located around the world, our work culture is characterized by open-allocation, where team members have a high degree of freedom and autonomy in choosing when to work, what to work on, and whom to work with.

Overview

Blockchains are not private enough for safe use by citizens, corporations, or dissidents.

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
- Ferveo: a DKG protocol for font running protection
- Cryptography research on Anoma’s blog
- Papers, such as Bandersnatch
- The PLONK by hand series (from our previous organization)
- The Demystification series (Supersonic, Fractal, from our previous organization)

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!

Senior Cryptographer

Aztec

At Aztec we believe privacy isn’t just a fundamental right, but a creative force for web3. Our goal is to unleash the full potential of decentralized technologies by building an open, privacy-first network with no compromises.

Privacy enables use cases that otherwise would not be possible and accelerates mainstream adoption. The next wave of web3 applications will require programmable privacy. Aztec’s technology empowers developers with the tools to build private applications and bring their ideas to reality.

Our journey started while building an application to bring syndicated loans on chain. We realized that our idea was a nonstarter without privacy. There were no solutions to offer privacy on public blockchains - so we sought out to build it ourselves. Since then, we've made industry-leading advances in cryptography, and deployed a private money platform and a private DeFi platform.

To realize our vision of implementing privacy on a public blockchain, we are building a world-class team of cryptographers, engineers, and ecosystem builders. Supporting us on this journey are leading investors including Paradigm, Variant, Consensys, and a_capital.

Role focus

Research techniques to improve both the constant and asymptotic performance of our cryptographic protocols
Perform literature reviews to identify new developments that could improve the Prover/Verifier efficiency of our cryptographic protocols (or replace them entirely)
Develop security proofs for our ZK-SNARK circuit architectures
Liaise with our applied cryptographers to assist them with implementing our cryptographic protocols in software

Required experience
- PhD-level qualification in cryptography or a related field
- 4+ combined years of experience in post-PhD cryptographic research in academia and/or industry
- Lead author in one or more papers in the field of zero-knowledge cryptography
- Familiarity with algorithms, data structures and basic programming concepts
- Ability to read and understand software implementations of cryptographic protocols written in C++
- A penchant for clear and comprehensive documentation
- Able to provide clear and constructive feedback for more junior cryptographers / applied cryptographers, mentoring where necessary
- A passion for blockchain, its potential, and what we’re trying to achieve.

What we offer:
- A highly competitive compensation package (including equity)
- Flexible and remote work environment
- 25 days holiday + bank holidays annually
- An opportunity to work at the cutting edge of blockchain and FinTech with a world class cryptography and engineering team
