Infrastructure Engineer, Platform

Company

OP Labs PBC, formerly known as Optimism PBC, is bringing Web2 usability to Web3 apps. Built by Ethereum developers, for Ethereum developers, OP Labs is the only secure decentralized blockchain infrastructure specifically intended to optimize and scale Ethereum. OP Labs develops open-source codebase software and operates optimistic L2 rollups to ensure Ethereum maintains the three central properties of blockchain: decentralization, security, and scalability.

OP Labs can be seen as an extension of Ethereum, from its philosophy down to its tech stack. They promote the growth and sustainability of public goods, through Retroactive Public Goods Funding, never to be captured by private commercial interests. They aim to make transacting on Ethereum affordable and accessible to everyone.

Backed by a16z and Paradigm, OP Labs has raised over $175M in funding, ensuring multiple years of runway, and is looking for an Infrastructure Engineer to support emerging phases of growth.

Role and Responsibilities

We are looking for an Infrastructure Engineer to help build and operate the foundational systems powering the OP Stack—the bedrock of the Optimism ecosystem.
This role is deeply focused on infrastructure, developer experience, and operational excellence. You’ll work at the intersection of protocol development and platform engineering to ensure our node infrastructure, tooling, and automation scale with the demands of the growing Superchain.
If you're passionate about high-performance infra, love working close to production systems, and want to help scale Ethereum in the real world—this role is for you.

What are the role responsibilities?

• Designing and implementing infrastructure to support automated deployments of the OP Stack across multiple environments.

• Owning critical pieces of infra from design through production with a focus on reliability, observability, and operational efficiency.

• Managing and evolving our Kubernetes-based infrastructure, ensuring reliability, scalability, and developer-friendly interfaces.

• Collaborating closely with protocol engineers to deeply understand their needs and unblock development across the stack.

What skills do you bring?

• Web3 experience: You’ve run, deployed, or contributed to blockchain infrastructure (e.g., running full nodes, working on validator infra, etc.).

• Experience running containerized systems in production using Kubernetes.

• Proficiency with Infrastructure-as-Code tools like Terraform, Ansible, Helm, or similar.

• Software engineering skills with Golang or another backend language; you think in systems, not scripts.

• A strong bias for ownership and high-agency mindset—you proactively seek out problems and solve them.

• Experience building tools that accelerate developer workflows and improve internal platform capabilities.
