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.

Your Role

As a Technical Support Engineer at Turnkey, you’ll help developers integrate, debug, and succeed with our SDKs and APIs across a range of environments — from React and mobile apps to backend servers and CLI tools. You’ll be the front line of technical expertise for customers building the next generation of crypto products on Turnkey.

You’ll spend your days reading code, investigating issues, and helping developers get unblocked fast — all while spotting opportunities to make our SDKs, docs, and platform better for everyone.

This is a deeply technical, hands-on role that blends debugging skill, customer empathy, and systems thinking. It’s perfect for someone who loves problem-solving, thrives in fast-moving contexts, and wants to be part of a team that sets the gold standard for developer experience.

What You’ll Do

• Triage, troubleshoot, and resolve customer issues across our SDKs and APIs covering web, mobile, and backend integrations
• Debug integrations across a variety of platforms and languages
• Identify, reproduce, and document bugs, partnering with engineering to drive them to resolution
• Support customers in setting up and verifying integrations, including configuration, auth flows, and signing
• Create and maintain example code, troubleshooting guides, and internal playbooks
• Spot patterns in recurring issues and propose fixes or improvements to documentation and SDKs
• Partner with Product and Engineering to relay feedback and insights from the field
• Help improve internal tools and processes to scale our technical support function

What We’re Looking For

• 2–6 years of experience in a technical support, solutions engineering, or software engineering role
• Prior experience in the crypto / web3 industry
• Strong working knowledge of TypeScript and React, with familiarity in React Native or other mobile SDKs
• Experience debugging APIs (REST, JSON, auth headers, 4xx/5xx errors, etc.)
• Strong problem-solving skills and comfort digging into unfamiliar systems to find answers
• Clear, empathetic written and verbal communication
• Desire to work in a fast-paced, startup environment with shifting priorities and lots of context switching

Style Points

• Experience supporting developer tools, APIs, or SDKs
• Prior experience with customer-facing technical roles in crypto, fintech, or security products
• Familiarity with observability tools (Grafana, Sentry, DataDog) or debugging tools (Postman, Chrome DevTools)
• Product-minded: you notice friction and think about how to remove it
• Strong curiosity for how secure infrastructure and crypto key management work

 What We Offer

• Full benefits, including medical, dental, vision, life, disability, HSA/FSA, 401(k)
• Paid parental leave
• Unlimited PTO
• $3,000/yr learning and development budget to attend industry conferences
• Multiple team offsites per year
• Lunch stipend
