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.

Waku is part of the Logos tech stack, a movement supporting the development of the decentralised web. Logos technologies lay the foundations for a freer internet upon which communities can evolve into network states. Each protocol in the Logos stack seeks to empower its users while upholding civil liberties and fundamental freedoms.

As a p2p messaging protocol, born from the original Web3 vision, Waku is a decentralized, censorship-resistant, privacy-preserving communication network that enables anyone to message, interact, collaborate, co-ordinate without worrying about surveillance or deplatforming.

We are a cypherpunk group, looking for other builders to join a principle-first organisation and build truly decentralised software.

• https://github.com/waku-org/
• https://discord.waku.org/
• https://forum.vac.dev/
• Logos Manifesto

Responsibilities:

• Implement open protocols for peer-to-peer secure messaging.
• Create and maintain a sustainable and fault-tolerant distributed system.
• Write and maintain Nim code (nwaku codebase).
• Understand and optimise the core functionality of complex software systems.
• Provide feedback on overall design decisions, and participate in code reviews.
• Use libp2p to build infrastructure-level protocols.
• Support platforms and operators using nwaku software.
• Maintain Golang, Rust and other language SDKs built on top of FFI bindings.

Ideally, you have

• A passion for privacy-preserving, decentralised and blockchain technology.
• At least 4 years of software engineering experience, with low-level/strongly typed languages (C/C++/Go/Rust).
• Experience building networking-heavy applications and p2p networking specifically.
• Familiarity with message propagation in loosely connected networks.
• Familiar with p2p building blocks such as gossiping, routing and discovery (DHTs), and Nat traversal.

Bonus points if you have experience in:

• Embedded systems development experience.
• Contributed to a blockchain-related, open-source project.
• Experience with Valgrind, or gdb, or gprof or perf.
• Experience with off-the-shelf networking stacks such as libp2p.

Compensation:

We are happy to pay in a mix of fiat and/or crypto. For more information regarding contributing to IFT: https://contributors.free.technology/

Hiring process:

1. Introduction call with People Ops team
2. Pair programming session with nwaku team member
3. Technical & Culture Interview with nwaku team lead
4. Interview with Waku lead
