Mysten Labs careers: remote jobs, culture and where they hire

Mysten Labs has raised $336M. The $36M Series A closed in December 2021, led by a16z with Redpoint, Lightspeed, Coinbase Ventures, Electric Capital, Standard Crypto, NFX, Slow Ventures, Scribble Ventures, Samsung NEXT, Lux Capital, Hack VC and Elad Gil. The $300M Series B in September 2022 valued the company at more than $2 billion and was led by FTX Ventures, with a16z crypto, Jump Crypto, Apollo, Binance Labs, Franklin Templeton, Coinbase Ventures, Circle Ventures, Lightspeed, Greenoaks and O'Leary Ventures. After FTX collapsed, Mysten bought back FTX's entire equity stake (about $101M invested, roughly 570,000 preferred shares) and its warrants on up to 890 million SUI tokens for about $96M in cash, approved by the Delaware bankruptcy court and completed in April 2023. The company also holds a SUI allocation designated in the tokenomics as the Mysten Labs Treasury.

Mysten Labs is the original contributor to Sui, a layer 1 blockchain built around an object-centric data model and the Move smart contract language, which the founders designed at Meta for the Diem project. Sui mainnet launched on May 3, 2023 and has since processed more than 16 billion transactions across roughly 230 million accounts, with DeFi total value locked holding around $1.2 billion in September 2026. The company also builds the rest of the stack: Walrus, a decentralized storage network that launched on mainnet in March 2025 and held 467TB of data by its first anniversary; DeepBook, an on-chain central limit order book with more than $17 billion in cumulative trading volume; Slush, the Sui wallet on web, browser extension, iOS and Android; and Hashi, a native Bitcoin orchestrator whose testnet went live on July 22, 2026 with more than 25 institutional partners including BitGo and Cumberland.

The 2026 roadmap leans toward privacy and AI agents: Seal MPC (June 2026) lets an AI agent transact on-chain without holding a private key, confidential transfers went into public beta on Devnet the same month, Walrus Memory gives agents portable memory that plugs into Claude, ChatGPT and Gemini, and Tessera (August 2026) is an open source prototype for KYC-gated B2B settlement with hidden amounts. Mysten Labs also invests in its ecosystem, with 16 disclosed investments including a $15M round it led for the on-chain video model Everlyn, and it hired Goldman Sachs' former head of digital assets for the Americas, Mustafa Al Niama, as head of capital markets in August 2025.

Evan Cheng, CEO and co-founder. Spent ten years at Apple (2005 to 2015), rising from senior compiler engineer to senior manager of compilation technologies and the LLVM backend team, and shares the 2012 ACM Software System Award for LLVM. Joined Facebook in 2015 as director of engineering for programming languages and runtimes, then led Novi Research and Diem blockchain R&D from 2018 to 2021; he started Mysten Labs at 50. B.S. in Computer Science and Math from Marietta College, M.S. in Computer Science from Syracuse University. Since Sam Blackshear's departure in August 2026 he also oversees technical direction.

Sam Blackshear, Co-founder and former CTO (left for Anthropic in August 2026). Creator of the Move language, which he designed from the ground up over nearly six years as a principal engineer at Meta for Libra/Diem. Before that, five years of academic research on static analysis for security and performance at the University of Colorado Boulder, where he earned a Ph.D. in programming languages. Announced on August 5, 2026 that he was "leaving Mysten Labs and joining Anthropic to work on defensive security research", staying on as an adviser to Sui builders and the Move Foundation.

Adeniyi Abiodun, CPO and co-founder. Product lead at Novi Financial for nearly three years, driving Diem and Move work. Earlier Head of Product for Blockchain at VMware and architect for blockchain cloud platforms at Oracle, and co-founder of PeerNova, a fintech using blockchain for enterprise data integrity. Before crypto he built financial applications and cloud architectures at HSBC and J.P. Morgan. B.Eng. in Electrical and Electronics Engineering from Queen Mary University of London.

Kostas Chalkias, Chief Cryptographer and co-founder. Lead cryptographer at Meta from 2019, covering Diem, the Novi wallet and payment encryption with WhatsApp, and before that lead cryptographer and blockchain engineer at R3 in London, where he worked on Corda and, with Mike Hearn, on the first real-world deployment of a quantum-safe signature scheme. Author of more than 50 papers and eight US patents (Hashwire range proofs, Winterfell ZKP, EdDSA aggregation), a white hat who has exposed flaws in exchange solvency proofs, and a professor of Web3 security at the American University of Sharjah. B.Sc., M.Sc. and Ph.D. in Security and Cryptography from the University of Macedonia.

George Danezis, Chief Scientist and co-founder. Professor of Security and Privacy Engineering at University College London since 2013 (part-time since founding Mysten), previously a researcher at Microsoft Research Cambridge (2007 to 2013) and a Turing Institute faculty fellow. Co-founded Chainspace, a sharded smart contract platform acquired by Facebook in February 2019, then served as a director-level research scientist at Novi designing privacy-preserving payments for Diem until July 2021. Co-designed Sui and the Narwhal and Tusk consensus protocols. B.A. and Ph.D. in Computer Science from the University of Cambridge, supervised by Ross Anderson. Based in London.

Mysten Labs is one of the few places to work on a production layer 1 with the people who designed it: the founders built Diem's consensus, cryptography and the Move language at Meta, and Sui, Narwhal and Tusk came out of the same group. Engineering postings ask for distributed systems and consensus, storage or networking protocol experience, and rate research experience (formal or informal) and open source contributions as pluses, so the work sits close to the literature.

Pay is published on every US posting and the bands do not vary by location within the United States. US benefits include medical, dental and vision for you and your dependents, a 401(k), a wellness stipend, short and long term disability, life and accident insurance, travel insurance, a privacy protection service, and family planning, gender affirming care and mental health programs.

The scope is wide for a 200-person company. Beyond Sui itself, teams ship a storage network, an exchange, a wallet with a card program on the way, a Bitcoin protocol and a handheld gaming console (SuiPlay0X1, built with Playtron), and the company runs experiments like a December 2025 field deployment in Bhutan with DHI testing how the chain behaves when connectivity vanishes. Adeniyi Abiodun's line, quoted by the company when Calyptus named it a Top 15 employer in Web3 in December 2025: "We have the most cracked team."

Three values are written on the careers page. "Focus on step change advancements": "We solve big, messy problems. We challenge the status quo and defy convention." "Everybody carries the box": the company says it hires "people who want to build for the greater good of Mysten, not for specific teams or individuals." "Operate with integrity": "Credibility matters. So we choose transparency and always seek diverse and divergent perspectives to strengthen our own. We keep things steady, open our ears and say what we mean." The about page adds that the company runs a full pipeline in parallel, research, development, productization and growth, and applies "the scientific and engineering rigor required to create trustworthy systems that operate in an adversarial environment."

The founding story sets the tone. Evan Cheng told Blockworks in 2022 that "some of our dreams couldn't be realized at Facebook due to regulatory pressure and the company being unable to adopt cutting edge technology aggressively," and told GamesBeat the team was "held back for about a year and a half" on Diem before deciding to "build the real thing." Postings say the same thing about priorities: "Crypto is constantly evolving, so our priorities do, too. What you worked on last month may not be what you work on today, and that excites you. You're not looking for a 9-5 job." Direct communication is listed as an expectation on the same posting.

Applications go through the Ashby board linked from each role. The process starts with one or two 45-minute phone interviews about your background, experience and interest in Mysten Labs. If there is mutual fit, most full-time candidates then do four separate 45-minute virtual interviews built to give a cross-functional view of breadth and depth, shaped differently for a cryptographer, a distributed systems engineer and so on. There is no announced take-home: coding rounds are judged live on how you solved the problem and on the structure and style of the code, efficient, effective, easy to read, maintain and upgrade, and able to turn an algorithmic idea into working code. Expect systems design and behavioral questions on how you have executed, challenged yourself, motivated others, made judgments and where you have failed. Recruiters usually respond within a week of the interviews finishing.

Mysten Labs may use AI-assisted tools to identify and evaluate candidates, with humans making the final decision, and employment is contingent on a background check covering employment history, education and criminal history. Genuine recruiter emails only come from the @mystenlabs.com domain and every role can be verified on the careers page. The partnerships role asks for 20% or more travel, often international.
