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.

What We're Looking For - Bachelors degree in Computer Science, Engineering, or a related field - 5+ years of experience in application or product security, ideally in fast-moving, high-impact or crypto-native environments - Strong understanding of web, mobile, and cryptographic security fundamentals (e.g. OWASP Top Ten, SANS/CWE Top 25) - Proficiency in programming and scripting languages (Typescript/Javascript, Go, Rust) and experience building secure systems from the code up - Hands-on experience with security testing tools and methodologies (static/dynamic analysis, pen testing, etc.) - Strong understanding of cloud, containerized, and runtime environments (AWS, GCP, Docker, Kubernetes), with the ability to embed security early in the SDLC - Excellent analytical, problem-solving, and communication skills, with a collaborative mindset for partnering across product and infrastructure teams - Curious, proactive, and passionate about building secure, reliable systems in a fast moving startup environment - A builder mentality; comfortable operating with ambiguity, tackling incomplete systems, and applying hands-on engineering experience to security challenges. Style Points - Familiarity with crypto or DeFi systems and their unique security challenges - Familiarity with threat modeling frameworks and cloud-native security tooling 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 - Multiple team offsites per year - Lunch stipend Turnkey is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, protected veteran status, or any other characteristic protected by law.
