- A passion for blockchain technology, privacy-preserving technology and decentralization.
- Strong academic or engineering background.
- Deep understanding of encryption and key exchange mechanisms.
- Experience with low level/strongly typed languages (C/C++/Go/Rust or Java/C#).
- Experience building networking-heavy applications and p2p networking specifically.
- Familiarity with message propagation in loosely connected networks.
- A solid grasp of p2p building blocks such as gossiping, routing and discovery (DHTs), and Nat traversal.
Bonus points if you have:
- Contributed to a blockchain-related, open source project.
- Experience with cryptography such as OTR, X3DH, Noise protocol.
- Experience with Nim.
- Experience with off-the-shelf networking stacks such as libp2p / devp2p.
Hiring process:
The hiring process for this role will be:
- Introductory chat with from our People Ops team
- Interview with Oskar, Vac Protocol Research lead
- Technical challenge / peer interview with Hanno or Sanaz from the Vac team
- Final interview with Jacek (Head of Research)
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. We’re looking for the new Protocol Engineer to join the team as soon as possible.
