About the role

In this role, you will play an essential part in building new components, communicating with our users to gather feedback, and working collaboratively with the rest of the team to make sure we solve important problems and provide a great user experience.
Lead critical projects end-to-end: design docs, implementation in Go/Solidity, reviews, rollouts, and post-mortems.
Build sequencer-adjacent services: screening APIs, proxies, attestations, and chain integrations (OP Stack/Arbitrum).
Deep dive on performance: profiling, load tests, flamegraphs, cache/queue tuning, and data-path optimizations.
Security first: threat modeling, key/secret management, IAM, least-privilege, audit/readiness practices.
Operational excellence: on-call participation, incident response, blameless retros, runbooks.
Mentor & multiply: guide teammates through designs, reviews, testing standards, and best practices.
Ecosystem awareness: track EVM/OP/Arbitrum changes, block building patterns, and bring actionable insights.

Knowledgeable about Ethereum and EVM
Experience with Go and Solidity.
Experience with AWS services such as Cloudwatch, DynamoDB, ECS.
Experience with Docker, ECS and Terraform
Experience with OP Stack and Arbitrum works is preferred
Desire to work with Rust.
Strong desire to further your education about Ethereum and contribute to the blockchain space.
Prior experience working remotely: strong personal organizational skills, a love for self-time management, and ability to work collaboratively with a team.
