Senior Solana Engineer – Core Protocol Architect
HYRO is building the next-generation decentralized asset-management protocol — non-custodial vaults, oracle-verified trader qualification, and transparent capital allocation on Solana. We’re not starting from zero: HYRO already has 30,000+ crypto traders, a profitable Web2 product, and is fully self-funded. Now we’re evolving this proven business into a fully on-chain Web3 protocol. We’re looking for a senior Solana engineer who can think in systems, design foundational primitives, and take ownership from architecture to deployment. What You’ll Build • Non-custodial vault architecture using PDA-based policies and on-chain execution • Challenge-based manager qualification system powered by real-time oracle updates • Verification and risk layers ensuring compliant, secure execution • Oracle-driven performance engine using our NATS → Solana pipeline • Governance + token primitives laying the groundwork for full decentralization You’ll work closely with our 3-engineer Solana team, backend team, and frontend team to bring the full protocol to mainnet. What We’re Looking For • Strong Rust + Solana fundamentals (accounts, PDAs, CPI patterns) • Ability to design secure, modular smart contract systems • Strategic thinking: you understand trade-offs, constraints, and protocol design • Comfortable owning architecture and mentoring other engineers Nice to have: DeFi experience, oracle/CE-X integrations, governance or staking mechanics, risk engines. Why Join HYRO • Real traction: 30k active traders, profitable, and growing • Real product: MVP core protocol already built and evolving fast • Real impact: Your work becomes the backbone of a category-defining system • Small, elite engineering team with high autonomy and no bureaucracy • Build something users already want — not a speculative experiment Join Us If you want to design meaningful systems, build at the frontier of Solana, and help transform a proven Web2 business into a decentralized protocol — we’d love to talk.
