About the Role
In this role you'll be working closely with the Head of Product to develop, maintain, and optimize the rollup stack offerings and customizations made possible by our leading Rollup-as-a-Service platform. You’ll develop product customizations that create entirely new or more efficient functionality, as well as help us expand our support for emerging L2s. We value people who can quickly obtain a deep technical understanding, are able to quickly create proof-of-concepts to validate entirely new approaches, and enjoy being self-directed and identifying the most important problems to solve.
Required Qualifications:
– 5+ years developer experience with Golang
– 2+ years working in the web3 space
– Ideally developing smart contracts and/or developing node software.
– 2+ years working in production with infrastructure tools or cloud DevOps experience: GCP, AWS, kubernetes.
It’s a bonus if you have:
– Familiarity with multiple programming languages, including but not limited to Golang, Rust, and Solidity.
– A strong background in distributed systems, cryptography, and network protocols.
– Have some experience hacking on the various rollups, understand the underlying components, and have opinions about the various trade-offs of those components and platforms.
– Have some experience with hacking on EVM node software.
We think you’ll find this work really exciting if you:
– You love to ship code!
– Not afraid to make decisions and act on them, even when or especially when you face uncertainty.
– Love rollups and their potential to exponentially scale Ethereum, and are excited about building best-in-class tooling and infrastructure for it and around it.
– You’re excited to architect, build, and deploy the systems, services, and integrations that help our rollups connect with other ecosystem partners.
– Have experience tinkering with optimistic and ZK rollups and deploying applications to the various chains.
– Can debug problems across the stack, such as networking issues, performance problems, or memory leaks
– Own problems end-to-end, and are willing to pick up whatever knowledge you're missing to get the job done
– Have contributed to product strategy and product roadmaps.
Our tech stack
Our infrastructure is built on Kubernetes, Postgres, and Cloud Tasks on GCP, and the products on top utilize a mix of React, Javascript/Typescript, Go, Rust, and Postgres. While we value experience with these technologies, we are primarily looking for engineers with strong technical skills and the ability to quickly pick up new tools and frameworks.
