Senior Software Engineer - Backend

About Us

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 talented engineers who are excited by the radical potential of crypto to change the world for the better. We are generalist engineers and constantly solving new problems and challenges. We are language-agnostic, though we do use Go, Typescript, and Rust in production and while we don't expect you to have a background in every technology we use, we do expect strong fundamentals and experience building scalable infrastructure.

What You'll Do

• Design and build systems from the ground up without cutting corners on security or usability


• Develop signing infrastructure and applications to run inside secure computing environments


• Collaborate effectively across the company to design and deliver the core product


• Write internal product specifications, external developer documentation, whitepapers, etc.


• Design and build new product features end-to-end driven by customer requests


• Assist in scaling out a world-class engineering team


• Develop thoughtful deployment processes and infrastructure to reduce the risks inherent in the software development lifecycle

What We're Looking For

• 5+ years of production engineering experience


• Experience with one of the following languages: Go, Typescript, or Rust


• Experience working with AWS, GCP, or other other cloud providers


• An understanding of modern application architectures with opinions on how they should be developed and deployed


• Experience building and operating large-scale, mission-critical infrastructure


• People who have experience building scaled crypto products


• A healthy amount of paranoia :-)

Style Points

• Experience developing against TEEs, HSMs, and other secure computing environments


• A deep understanding of the Linux operating system and how to reduce the surface area of applications deployed on top of it


• Expertise in threshold signing systems and a desire to stay on the cutting edge of production-grade cryptography


• Actively tracking developments in the crypto ecosystem and opinionated on where it is going

What We Offer

• Full benefits, including medical, dental, vision, life, disability, HSA/FSA, 401(k) - detailed benefits overview available as we get further in the process


• Paid parental leave


• Unlimited PTO 


• $3,000/yr learning and development budget to attend industry conferences
