About Vac

Vac builds public good protocols for the decentralized web. We do applied research based on which we build protocols, libraries and publications.

This role is within the the Vac Incubator Project “Nescience”, which is developing a state separation architecture with selective privacy.

The role

In this role, you will be responsible for maintaining our Rust code base, transforming research prototypes into production and collaborating with researchers, prototyping ideas, measuring performance, and conducting code reviews, and shaping engineering culture.

Your responsibilities will include planning, implementing, and shipping end-to-end functionality in monthly release sprints. As well as profiling bottlenecks, hardening cryptographic components, and writing property-based tests.

The ideal candidate should be comfortable with modern cryptography, familiar with zero-knowledge virtual machines (zkVMs) and experienced with blockchain or other peer-to-peer systems, and motivated by decentralisation and privacy.

Key responsibilities

• Write and maintain Rust code base.
• Develop new solutions based on research output.
• If necessary, participate in research.

You ideally will have

• 4-5 Years of Rust experience.
• Experience writing asynchronous code in Rust using Tokio.
• Solid understanding of cryptography.
• Understanding, how zkVM’s work.
• Experience in, and passion for, blockchain technology.
• A strong alignment to our principles.

Bonus points if

• Experience writing code using libp2p.
• Worked with RISC0.
• Participated in building blockchain projects.

[Don’t worry if you don’t meet all of these criteria, we’d still love to hear from you anyway if you think you’d be a great fit for this role. Just explain to us why in your cover letter].

Hiring process

The hiring process for this role will be:

• Interview with our POps team
• Interview with Nescience team lead
• Pair programming task with the Nescience team
• Interview with Vac team lead
• The steps may change along the way if we see it makes sense to adapt the interview stages, so please consider the above as a guideline.

Compensation

The expected compensation range for this role is negotiable, dependent on how we assess your skills and experience throughout our interview process. We are happy to pay in any mix of fiat/crypto.

Each protocol in the Logos stack seeks to empower its users while upholding civil liberties and fundamental freedoms.

The Role

Nomos requires a specialized role to bring in-depth knowledge and experience with ZK proofs and related tools and frameworks. This expertise will facilitate expedited prototyping, research, design of the proving system, and help in developing ZK-friendly solutions for the requirements of multiple components of the Nomos blockchain. The constant flux of tasks, varying in size and scope, requires a team member who can seamlessly integrate into the team and contribute immediately.

Key Responsibilities

• Develop an in-depth understanding of the multi-layered architecture of Nomos and how Zero Knowledge proofs can be effectively utilized at various stages.
• Collaborate with other researchers and developers to ensure that Nomos’s systems and protocols are efficiently designed and implemented.
• Address and solve upgradeability concerns related to ZK schemes and ensure consensus proofs are ZK-friendly.
• Design and help implement privacy-centered protocols that require the use of ZK proofs.
• Evaluate and integrate ZK tools and frameworks to optimize the performance and efficiency of our systems.
• Stay abreast of the latest developments and trends in the field of Zero Knowledge proofs and blockchain technology.
• Provide support and guidance to the team on ZK proofs related issues.

You ideally will have

• A strong technical background, preferably with a degree in Computer Science, Mathematics, or a related field (PhD-level or equivalent in industry); relevant research experience.
• Extensive knowledge and experience with Zero Knowledge proofs, cryptography, and blockchain technology.
• Deep understanding of Zero-Knowledge proof systems (zk-SNARK, circom, Plonk/Halo2, zk-STARK), elliptic curve cryptography, and circuit design.
• Previous experience in a similar role, where you successfully contributed to the development of complex systems using ZK proofs.
• Strong problem-solving skills and the ability to make informed decisions quickly.
• The ability to work collaboratively in a team environment and communicate complex concepts clearly and effectively.
• A passion for the blockchain technology and a desire to push the boundaries of what is currently possible.
• Knowledge of current ZK tools and frameworks, and the ability to learn new tools quickly.

Bonus if

• Knowledge of other privacy-preserving technologies (MPC, FHE).
• Distributed systems knowledge.
• Knowledge or interest in other areas related to blockchain systems.
