The Senior Full Stack Engineer will own features and products end to end across frontend interfaces and backend infrastructure, collaborating with product, design, operations, finance, external partners, and customers to prototype, launch, and iterate.

Responsibilities

• Fluency with relational databases and SQL
• Proven ability to ship production systems, frontend and backend, with high uptime and minimal maintenance burden
• Strong product instincts and an eye for good design; you can work from a Figma file but you'll also push back when something doesn't feel right

• MVP mindset: you know how to scope a milestone, ship it, learn from it, and iterate fast
• Strong commitment to clean code principles and automated testing
• Deep understanding of API design, versioning, documentation, and modern authentication patterns
• Excellent communication skills and experience collaborating across product, design, and operations in remote, asynchronous environments
• Experience in fast-paced, high-growth startup environments where you've worn many hats

• Familiarity with performance profiling, latency reduction, and service-level adherence
• Background in designing and operating event-driven architectures
• Expertise in Docker, Kubernetes, Prometheus, and Grafana
• Passion for building tools, internal or external, that meaningfully improve how people work with money
• Hands-on experience building in crypto, including working with onchain libraries and services, and integrating with blockchain infrastructure
• Experience integrating or interacting with blockchain node software (e.g., Geth, Solana validators)
