Senior Staff Software Engineer Protocol at SeiLabs

At Sei Labs, we are building the foundation for the next generation of digital finance. We created the Sei Blockchain, which is the first parallelized EVM Layer 1 network designed to handle the massive scale required for global adoption. Our team is a collection of veterans from industry leaders like Google, Robinhood, and Nvidia, all united by the goal of bringing Web3 technology to the masses. With over $30 million in backing from top-tier investors such as Coinbase Ventures and Jump Crypto, we are moving fast to build a high-performance ecosystem that bridges the gap between traditional web speed and decentralized security.

The opportunity

We are looking for a Senior Staff Software Engineer to join our protocol team and take a lead role in shaping the core architecture of our blockchain. This is a high-impact position where you will design and optimize the foundational layers of our network. You will be at the center of our technical strategy, working on everything from consensus mechanisms to state management. If you are someone who thrives on solving complex systems design challenges and wants to push the limits of what a decentralized network can achieve, you will find a home here.

A day in the life

• You will write and maintain the core code that powers the Sei Blockchain, focusing on critical areas like consensus and state management.
• You will proactively seek out ways to improve our infrastructure, driving performance optimizations that keep our network running at peak efficiency.
• You will partner with our frontend team to refine our REST API, ensuring that our customers have the robust tools they need to build on our platform.

Who you are

You are a seasoned infrastructure engineer with at least five years of experience under your belt. You have a track record of building or scaling Layer 1 blockchains and understand the nuances of high-performance systems. We are looking for a technical leader who can plan large-scale projects and guide a team toward long-term success. You possess excellent judgment when it comes to prioritizing tasks, and you have a history of implementing new processes that make the entire engineering team more efficient. You are fluent in English and ready to tackle complex problems in a fully remote, global environment.

Why you'll love it here

We believe in giving our team the freedom to do their best work from anywhere in the world. As a fully remote organization, we prioritize results and collaboration over physical office presence. You will be working alongside some of the brightest minds in the industry, tackling challenges that have a direct impact on the future of blockchain technology.
