Senior Solana Engineer

Intro

M0 is the shared infrastructure where businesses launch their own branded stablecoins and financial institutions power them. Built on a common standard, every stablecoin on M0 is interoperable and liquid from day one - giving businesses programmable control over how money moves in their ecosystems, and giving financial institutions the most advanced issuance stack in the industry.

M0 is seeking a Solana Smart Contract Engineer who will play a fundamental role in shaping the future of our organization. As a Solana Smart Contract Engineer, you will architect and develop Solana programs in Rust and extend M0’s existing issuance infrastructure with a focus on Token-2022. The ideal candidate is self-driven with strong ownership instincts and a bias for action, brings a computer science background or deep-rooted passion for tackling hard technical problems, and has substantial expertise across Web3 applications and infrastructure. You thrive on deadlines, communicate clearly across functions, and do your best work in a fast-paced environment.

Key Responsibilities

• Architect and develop Solana programs in Rust, using Anchor and/or native frameworks.
• Maintain and extend M0’s existing issuance infrastructure, with a focus on Token-2022 extensions.
• Optimize programs for compute unit usage, account size, and transaction packing.
• Participate actively in code and design reviews.
• Prepare codebases for third-party audits, including writing comprehensive tests, invariants, and fuzz harnesses.

Qualifications

• 5+ years of software engineering experience.
• 2+ years writing production code in Rust.
• Proven track record of deploying and maintaining complex Solana programs in production.
• Solana-native: deep working knowledge of the account model, rent, transaction limits, versioned transactions, address lookup tables, etc.
• Strong familiarity with the SPL Token program, Token-2022, and Associated Token Accounts.
• Hands-on experience with the broader Solana DeFi ecosystem.
• Experience with cross-chain messaging and bridging protocols — Wormhole NTT, LayerZero, Hyperlane, or Chainlink CCIP.
• Basic familiarity with Solidity and EVM development, sufficient to reason about cross-chain message flows and equivalent contract behavior on both sides.

Nice to Have

• Previous experience at a high-growth DeFi protocol, ideally one handling stablecoin issuance, lending, or RWAs.
• Experience with Solana security tooling and auditing workflows.
• Contributions to open-source Solana programs, SDKs, or developer tooling.
• A degree in computer science or a related field.
