Job Description & How to Apply Below

The Monad Foundation is a team of dedicated ecosystem and community builders who are on a mission to massively grow the impact of decentralized tech. We believe that the Monad blockchain--the performant and parallel EVM Layer 1--will help decentralized apps eat the world.

The Role

We're looking for a Senior Dev Ops Engineer with deep Linux expertise and a strong track record of building infrastructure and testing automation from scratch. You'll join a small, talented team of systems experts to extend the testing, tooling, and operational backbone of a high-performance, next‑generation Layer 1 blockchain.

What You Will Do
  • Build and maintain testnets and test automation for components of the Monad blockchain
  • Prototype new deployment patterns across validator and full-node topologies
  • Design and run performance benchmarks and load tests to surface bottlenecks before they reach production
  • Drive observability, alerting, and security across the stack
  • Define best practices for node operators & support them
  • Develop tooling for internal & external use
  • Participate in on‑call rotation for production support
Who You Are
  • 2+ years of Dev Ops experience at a professional RPC provider / professional validator company / L1 blockchain
  • 3+ years of experience with Infrastructure as Code and Configuration Management (Terraform, Ansible)
  • 2+ years of experience with container technologies (Docker, Kubernetes)
  • Proficient in bare metal server management and scripting
  • Proficient in at least one back-end language such as Python or Go
  • Hands‑on experience running highly available containerized systems on Kubernetes, including packaging (Helm) and Git Ops‑style deployment (FluxCD, ArgoCD, or Git Hub Actions)
  • Strong experience with a major cloud provider (AWS preferred)
  • Comfort with network setup, maintenance, and troubleshooting at the systems level
  • Experience operating open‑source observability stacks (Prometheus, Grafana, Loki, or similar)
  • Proficient with command‑line git
  • Able to juggle competing priorities and move quickly during incidents
  • Fluent written and spoken English
Why Work with Us
  • Challenging problems. You’ll tackle deeply complex and technically demanding problems, with autonomy and impact.
  • Endless Opportunity for Impact. The Ethereum Virtual Machine (EVM) standard is ubiquitous, but existing EVM-compatible chains are slow and bandwidth‑constrained. Monad’s core innovations offer developers and founders the best of both worlds (portability and performance) and are a game‑changer to power global on‑chain finance.
  • The right team. You’ll be part of a world class team, who are exceptional and highly‑motivated.
  • Culture. We’re a lean team working together to achieve very ambitious goals. We are united in our culture of collaboration, low ego, and high‑quality output.
  • Strong Ecosystem. The broader Monad ecosystem has attracted support from leading investors, builders and long‑term contributors.
