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
