Principal Security Engineer (Solana)

About us OpenZeppelin is the security standard onchain finance is built on. Founded in 2015, our mission is to accelerate the world's transition to an open financial system, built on open standards and secured by rigorous research. Our open-source Contract Libraries have facilitated over $35 trillion in onchain value and are used by 10 of the top 10 tokenized money market funds and 9 of the top 10 stablecoins by market cap. We combine AI-native security tooling with deep research and a decade of audit expertise to support leading institutions and crypto-native teams shaping the next generation of digital assets like DTCC, Fidelity, Coinbase, Uniswap, Aave, the Ethereum Foundation, and many more across the full secure development lifecycle. Please note: Always refer to OpenZeppelin's official job page for the most accurate information about our open roles, as we have seen multiple third party job sites posting inaccurate information. The Secure Development team ❤️ OpenZeppelin is the security partner of choice for the most important protocols in Web3. Our Secure Development team sits at the intersection of building and breaking: we design, implement, and harden production-grade libraries and smart contracts for leading projects across EVM, Starknet, Stellar/Soroban, Arbitrum Stylus, Aptos, and beyond, often as an embedded extension of the client's engineering team. We work the way the rest of the industry will five years from now. Every developer on the team is a fully AI-native engineer, supported by outstanding internal AI tooling built for every phase of secure development. Developers own their workstreams end-to-end — agents amplify their effectiveness, and peers, security researchers, and external auditors provide rigorous review on every piece of work that ships. We are looking for a Principal Solana Developer to set the technical direction for our work on the SVM. This is not a seat on an existing Solana team: you are the person who defines what OpenZeppelin's Solana practice looks like, in the open and under your own name, so your reputation compounds with ours. The engagement Your first focus is our confidential computing track on Solana: porting onchain fully homomorphic encryption primitives to the SVM runtime, designing the confidential token standard and the SDK patterns on top of it, and building the developer abstractions that make it usable. It runs into 2027, it is public, and it is coordinated directly with the Solana Foundation. The open design questions are yours to own: access control list storage cost, program upgradability and governance, and how to express confidential DeFi flows idiomatically on Solana rather than transliterating them from EVM. Beyond that engagement, you are the SVM technical lead across our portfolio: shaping how we scope and staff Solana audits, contributing to our open source libraries and tooling, and giving the security research team the depth they need when a program lands on their desk. Within this, you will: Lead our Solana workstreams end to end, from architecture and implementation through audit preparation, deployment and post launch hardening. You make the calls, and you bring others with you. Build production grade programs and libraries where security is the primary constraint, not an afterthought. Most of your code will be reviewed by world class auditors. Own the hard design questions of a young ecosystem: storage and compute cost models, upgradability and governance, and idiomatic patterns for primitives with no Solana precedent yet. Run client facing roadmap and design discussions independently. You are the technical voice in the room, and the person a client's own engineers want to argue with. Raise the level of everyone around you: review the team's Solana work, set the standards it is held to, and shorten the ramp for the people coming in behind you. Represent OpenZeppelin in the ecosystem: engage with the Solana Foundation, core teams and standards discussions, p…
