About Us:
ZKV operates high-performance and resilient infrastructure for blockchain networks. We are a lean expert team with a diverse skill set driven by a mission to promote privacy, zero-knowledge, and decentralized systems tech, the next frontiers of Web3. Our dedication has made us one of the top validators on Sui, Celestia, Celo, Noble, Espresso, Mina, Polkadot, Cosmos, and more.
The Role:
We seek a passionate and experienced DevOps / SRE Engineer to join our team and contribute to our mission of advancing the state of distributed systems and cryptography. You will be part of our DevOps team, which operates at the forefront of distributed systems and zero-knowledge (ZK) technology. We run Proof-of-Stake validators, shared / decentralized sequencers, ZK provers and bridge operators on many different networks. You will be responsible for onboarding new networks, maintaining existing infrastructure and keeping an understanding of emerging trends in the ecosystem.
Key Responsibilities:
Designing, Deploying and Maintaining critical infrastructure for the continued operations of Proof-of-Stake validators using Ansible roles and other Infrastructure as Code solutions.
Monitoring infrastructure components to catch and resolve issues quickly using Prometheus, Grafana, and PagerDuty.
Proactively making changes to infrastructure components to prevent future issues.
Using top-of-industry security insights to further secure infrastructure components.
Automating existing business processes.
Continuing our pursuit to decentralise blockchain operations to different hosting solutions, including cloud, bare-metal providers, and self-hosting in our datacenter colocation.
Proposing improvements to existing infrastructure to improve resiliency, developer experience and workflow improvements.
Creating technical contributions for the projects we work with that help them get closer to their goals.
Requirements
Extensive experience managing Linux systems through Infrastructure as Code.
Prior knowledge and experience working with relevant distributed / p2p systems, e.g., Mining, PoS validation, MEV.
Have operated Proof-of-Stake validators before or have demonstrated development experience on these systems.
Prior knowledge of Infrastructure as Code tools like Ansible and Terraform / OpenTofu.
Experience using orchestration tools like Kubernetes and Docker.
Being able to take ownership of all changes and systems you interact with, we aim for > 99.99% uptime.
Have experience working on small teams & in a startup environment.
Should be self-driven, proactive and be able to work independently.
Shows an interest in ZK technologies
Has a big passion for anything blockchain, cryptography, and decentralized systems.
Nice to Have
Experience with Go, Rust, Python and/or JavaScript.
Contributions to open source projects, especially in the ecosystems we’re active in.
What we offer
Full-time at a competitive salary
Remote work - must be able to join contribution hours (2PM - 4PM UTC). The ideal candidate is within ±2h from CET for the first 3 months of onboarding.
Unlimited PTO with a high level of freedom and autonomy for your work.
Work together with experts in the blockchain, cryptography and ZK spaces.
Travel required for key conferences and team offsites.
We value excellence, humility, & curiosity. We are looking for someone with an interest in working at the forefront of distributed computing.
What is Zero-knowledge?
Zero-knowledge is a concept in cryptography that allows two parties to exchange information without revealing any additional information beyond what is necessary to prove a particular fact
In other words, zero-knowledge is a way of proving something without actually revealing any details about the proof
Here are some examples of zero-knowledge:
- Password authentication: When you enter your password to log into an online account, the server doesn't actually know your password. Instead, it checks to see if the hash of your password matches the stored hash in its database. This is a form of zero-knowledge because the server doesn't know your actual password, just the hash that proves you know the correct password.
- Sudoku puzzles: Suppose you want to prove to someone that you've solved a particularly difficult Sudoku puzzle. You could do this by providing them with the completed puzzle, but that would reveal how you solved it. Instead, you could use a zero-knowledge proof where you demonstrate that you know the solution without actually revealing the solution itself.
- Bitcoin transactions: In a Bitcoin transaction, you prove that you have ownership of a certain amount of Bitcoin without revealing your private key. This is done using a zero-knowledge proof called a Schnorr signature, which allows you to prove ownership of a specific transaction output without revealing the private key associated with that output.
- Secure messaging: In a secure messaging app, you can prove to your contacts that you have access to a shared secret without revealing the secret itself. This is done using a zero-knowledge proof, which allows you to prove that you have access to the secret without actually revealing what the secret is.
