Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and build transaction parsing, validation, and broadcasting infrastructure across multiple blockchain protocols. Develop protocol-specific libraries and collaborate on core product capabilities and technical documentation.
Requires 5+ years of production engineering experience with strong Golang skills and deep familiarity with crypto protocols, specifically EVM. Experience building large-scale, mission-critical infrastructure on cloud providers is essential.
Turnkey is developer-first infrastructure for private key management, making it simple to create wallets, sign transactions, and automate on-chain actions through one elegant API, without ever exposing sensitive key material. Founded by the team who scaled Coinbase Custody from zero to a $100M+ ARR business and helped protect over $100B in crypto assets, Turnkey is tackling crypto security at its foundational level. Our mission is to make strong cryptography the default across the open internet the same way AWS made scalable computing the default for software.
Our team is low-ego, high-agency, and high-autonomy, with a significant amount of combined experience in cryptography, security, and low-level systems. We're building the trustless, programmable infrastructure that will power the next wave of mass-market crypto applications and we're looking for people who want to shape what that future looks like.
We are looking for a crypto-native engineer to join our Transaction Management team. This team is at the heart of what Turnkey does, building the systems that orchestrate transactions and read onchain state across a wide range of blockchain protocols. We write primarily in Go and operate at the intersection of rigorous engineering and deep protocol knowledge.
Please note that while the team is remote, we are only considering candidates who are physically based in the United States and Canada at the current time.
