Job summary

True Markets is building the next generation of digital asset trading from its New York City office. The DeFi Engineer owns backend services in Go for onchain quoting, execution, and settlement across Solana and EVM chains, with end-to-end ownership from design to production.

Join a senior, small-team environment emphasizing crypto fundamentals, tool-assisted development, and rigorous testing of money paths. Expect collaboration, autonomy, and growth in a fast-moving market.

Qualifications

• 5+ years building and shipping production backend services.
• Deep proficiency in Go, or strong fluency in another statically typed language and demonstrated speed picking up new ones.
• Hands-on Solana or EVM development — RPC, transaction construction, signing, and confirmation.
• Strong grasp of crypto fundamentals: wallets, tokens, gas, and how a swap settles onchain.
• AI-native: Claude Code or comparable agentic tooling as a daily force multiplier, with strong instincts for when to trust it, when to verify, and how to push it harder.
• Strong written communication and high autonomy in a small team.

Responsibilities

• Design, build, and ship backend services in Go across quoting, execution, and settlement.
• Own projects end to end, from design decision through migration, rollout, and production verification.
• Integrate onchain venues and providers, including DEX aggregators, perp venues, and signing infrastructure.
• List and configure new spot and perpetual markets, including price sources and asset metadata.
• Maintain market data ingest: onchain and exchange price feeds, time-series storage, and the APIs that serve them.
• Debug failed transactions across the stack, from service logs to onchain execution.
• Support production: respond to alerts, run deploys, and confirm fixes in dashboards.
• Review others’ work and set the standard for how changes to the money path are scoped and tested.
