About Sei

Sei Labs builds open sourced technology for the high-performance Sei Blockchain, the first parallelized EVM Layer 1 blockchain designed to scale with the industry. The unique optimizations built into Sei enable Web3 applications to reach Web2 level scale and performance, driving the mass adoption of digital assets.

The Sei Labs team is comprised of former Google, Goldman Sachs, Robinhood, Nvidia, and Databricks veterans dedicated to onboarding the next billion users onto a vibrant ecosystem of applications.

Sei Labs has raised over $30M from top investors including Jump Crypto, Multicoin Capital, Coinbase Ventures, Distributed Global, Hudson River Trading, and Flow Traders.

We're a globally distributed team with a fully remote workforce. Check out our website and docs for more details.

Position Overview

We’re looking for a Research Scientist to join our team at the frontier of blockchain research and engineering. This is an opportunity for an early-career researcher (postdocs also welcome) to work on novel, unsolved problems in distributed systems, cryptography, and mechanism design — and see their work directly shape the next generation of blockchain infrastructure.

This is a rare chance to work on problems that are unsolved both in academia and industry, and to see your research deployed at scale. You’ll be joining a small, ambitious team where researchers and engineers work side by side to invent the future of decentralized systems. Some of our current research streams include: Modelling MEV in a multi-concurrent proposer blockchain context. Designing improved encryption constructions for private data availability (DA), and Advancing consensus protocols to improve scalability and robustness.

What You’ll Do

• Conduct original research in blockchain systems — bridging theory, cryptography, and practical engineering constraints.

• Collaborate closely with engineers to translate research into systems that run at 5 gigagas/second scale.

• Publish papers and technical reports that advance both the academic and practitioner communities in web3.

• Partner with leading researchers at other blockchain companies and universities to push the boundaries of what’s possible.

• Influence the engineering direction of our blockchain by grounding design decisions in rigorous analysis.

What We're Looking For

• PhD in Cryptography, Computer Science, Mathematics, etc. with a strong interest and existing research in Blockchain adjacent technologies

• 0–2 years of post-PhD experience (Postdocs / upcoming PhD’s welcome to apply)

• Strong background in one or more of: cryptography, distributed systems, consensus, game theory, or applied mathematics

• Strong curiosity for blockchain/web3 research, with motivation to shape production systems and protocols, not just papers
