About Dragonfly
Dragonfly is a global investment firm focused on the future of money, markets, and intelligence. With origins in crypto and over $3.5 billion in assets under management, we invest in generational companies and protocols across the frontier of finance and technology. We're a team of seasoned VCs, technologists, and markets experts with deep roots in New York, Silicon Valley, and Asia. We've published some of the industry's most widely read research on stablecoins, market structure, decentralized finance, networks, protocol security, and increasingly, the intersection of finance and AI.
This is an application to join our talent network. This is not a listing for an internal role at Dragonfly.
We’re actively sourcing for a Founding Smart Contract Engineer (Solana/SVM) to join a small, well-capitalized team building stablecoin infrastructure. You’ll be the person the rest of the company looks to on anything blockchain, with a real voice on product and who gets hired next.
Location: NYC (priority), open to exceptional candidates in SF or remote across the USA
What We’re Looking For:
- Experience writing, deploying, and maintaining smart contracts that real users have interacted with on mainnet
- Exceptionally strong Rust developer: storage layout, gas, reentrancy, upgrade patterns, failure modes of SVM tooling
- Working Solidity experience
- Experience building systems where smart contracts coordinate with an off-chain system of record (atomicity, idempotency, recovery paths)
- Security mindset by default: invariants, threat models, “what’s the worst thing an adversary could do”
- Expert with Anchor, Solana CLI, LiteSVM, Bankrun, and the modern Rust testing and fuzzing stack
About the Role:
- Design and implement core integrations with Solana DeFi protocols and embedded wallets
- Build out the cross-chain messaging layer, evaluating, integrating, and extending leading protocols
- Own development of protocol contracts end to end
- Drive the external audit process and design ongoing monitoring and incident response for live contracts
- Make architectural calls on upgradeability, key management, pause/recovery flows, and economic safety
- Work with EVM chains as required
Compensation
- Mid: $150,000–$200,000 + meaningful equity
- Senior: $200,000–$250,000 + meaningful equity
The compensation range reflects variation by seniority, location, and hiring company. Final compensation is confirmed with the specific hiring company.
Even if you don’t match every point above but have relevant experience in Solana, smart contracts, or crypto infrastructure, we encourage you to apply. There may be other opportunities that fit your skill set.
Process:
- We’ll confidentially match you with portfolio companies aligned with your background, skill set, and interests
- If mutual interest exists between you and a team, we’ll facilitate a warm introduction
- If there isn’t a match today, we’ll keep you top of mind for future opportunities
Submit your information below, and we’ll reach out if there’s a potential fit.
