This role will require being full-time onsite at our San Francisco office to support collaborative team dynamics and innovative problem-solving.

BitGo is the infrastructure backbone of the digital asset economy, trusted by the world's leading institutions to secure and move billions in crypto every day. We're looking for a Senior Software Engineer to join our Growth team and help shape the future of custody, growth, and mobile products. If you want to work on systems that genuinely matter - where scale, security, and correctness aren't nice-to-haves but existential requirements, this is the role for you.

You'll work on systems where the stakes are real, the engineering bar is high, and AI-first development isn't a buzzword - it's how we operate. BitGo moves fast, ships with discipline, and builds for the long term. Come help us deliver trust in digital assets.

What You'll Do:

• Architect and build high-scale APIs, libraries, and services that power custody and growth products used by the world's most sophisticated crypto institutions
• Take full ownership of features from whiteboard to production, including customer integration and post-launch iteration
• Design and document developer-facing APIs that delight third-party builders and internal teams alike
• Ship with AI at your side. Leverage LLMs, AI coding agents, and intelligent tooling to dramatically accelerate design, implementation, and review cycles
• Partner with PMs, designers, and engineers across the stack to define and deliver experiences that raise the bar
• Write code you're proud of: clean, well-tested, and built to last
• Hunt down performance bottlenecks, squash bugs, and leave the codebase better than you found it
• Mentor peers through code reviews, architectural guidance, and a culture of continuous craft improvement
• Stay ahead of the curve. Evaluate and adopt emerging technologies (including new AI tooling) that make the team faster and the product better

What You'll Bring:

Required:

• 6+ years of backend/server-side engineering experience, with a track record of shipping production systems at scale
• Sharp instincts for algorithm design, problem decomposition, and complexity tradeoffs
• Fluency with AI-assisted development. You actively use tools like GitHub Copilot, Cursor, or Claude to accelerate your workflow, and you know when to trust them and when not to
• Experience prompting and integrating LLMs into development workflows: code generation, test writing, documentation, and debugging assistance
• Familiarity with AI agent frameworks or autonomous coding tools and how to supervise, evaluate, and course-correct their outputs
• Hands-on experience with PostgreSQL and MongoDB in production environments
• Deep expertise in RESTful API design and the principles behind great developer experience
• Practical experience with microservices and service-oriented architectures
• Solid testing discipline - unit, integration, and functional coverage as a first-class concern
• Strong Git/GitHub workflow hygiene: branching strategies, code review culture, CI/CD pipelines
• Ability to move fast, make decisions under ambiguity, and recalibrate quickly
• Bachelor's degree in Computer Science, Applied Mathematics, or a related technical field
• Genuine curiosity about and understanding of cryptocurrencies and blockchain technology

Preferred:

• Experience building institutional crypto products (custody, wallets, trading infrastructure)
• Proven track record shipping and maintaining public-facing production APIs
• Strong command of Golang, Kotlin or TypeScript, Node.js, and Express
• Full-stack capability with React, comfortable owning a feature end-to-end
• Experience working directly with clients or business partners to shape requirements
• Familiarity with any of: digital wallets, KYB/onboarding flows, growth platforms, or mobile crypto UX
• Experience evaluating or fine-tuning AI models for domain-specific tasks
