Mysten Labs is developing crucial infrastructure to power a more decentralized internet, transforming how people connect and share information online. Backed by Lightspeed, a16z and Redpoint.
About the role
We’re looking for a Senior Security Engineer to help protect the Sui ecosystem. You’ll uncover vulnerabilities, build monitoring tools, and assess economic risk across DeFi protocols. Working closely with external protocol teams and Mysten’s own DeFi products, including DeepBook, you’ll help address risks before they become incidents and strengthen security across the ecosystem Rigor: you verify claims against bytecode and chain state, build known-clean checks into your tools, and say what you did not verify.
What they're looking for
- Bachelor's degree in Computer Science, Computer Engineering, a relevant technical field, or equivalent practical experience
- Proficiency in TypeScript and Python, and comfort with Rust. Ability to write SQL over large datasets and to work with blockchain indexers and data warehouses
- Experience reading smart contract code at source or the bytecode or disassembly level, or evident ability to learn it quickly. Move experience is a plus, not a requirement, Solidity or Rust smart contract experience transfers
- Rigor: you verify claims against bytecode and chain state, build known-clean checks into your tools, and say what you did not verify
- Strong written and verbal communication, including the ability to influence external teams you have no formal authority over
- Interest in the web3 space is required

Responsibilities
Build and run continuous monitoring of the Sui DeFi ecosystem for security and economic risk: oracle issues, misconfigurations/bad economic parameters, solvency and bad-debt exposure under price shocks, liquidation capacity against on-chain liquidity depth, accounting-versus-positions reconciliation, invariants.
Extend security team tooling, both precise static analysis tooling and proprietary agent skills.
Measure and drive compliance with the DeFi security recommendations across supported protocols: run the recurring compliance...
