Senior Solana Engineer

Intro

M0 is the modular stablecoin infrastructure. It gives businesses everything they need to launch a stablecoin built around their product, with separate, configurable layers for application, distribution, and issuance. Choose your regulated issuer, with the option to switch them later. Design how your stablecoin behaves with templates and custom logic. Tap shared liquidity across the network from day one. Other stablecoin platforms bundle every layer into a single fixed stack. M0 keeps them independent, so your stablecoin stays yours.

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.
