● Support testnet deployments, monitor health, and manage upgrades.
● Collaborate with protocol and engineering teams to integrate DevOps with zk circuits
and infrastructure.
● Implement logging, alerting, and monitoring for proving-related services.
Technical Skills
● Strong experience in DevOps (Nix/Nixos, Terraform, Docker, GitHub Actions, etc.).
● Experience with OCaml projects — understanding build systems like Dune,
managing dependencies.
● Experience deploying and managing distributed systems or proving clusters.
● Comfortable with Linux systems administration, shell scripting, and automation.
Soft Skills
● Able to work independently with minimal supervision.
● Comfortable owning projects from setup to maintenance.
