About The Position

We're seeking a Senior Fullstack Engineer to take end-to-end ownership of features and products across the stack, from Agora interfaces to reliable backend infrastructure. You'll work closely with product, design, operations, finance, and our external partners and customers to gather requirements, prototype quickly, and ship with confidence. You have strong product taste, a bias toward MVP thinking, and you're as comfortable reasoning about user experience as you are about backend systems, API designs or database schemas. Our stack includes TypeScript, React, REST APIs, Docker, Kubernetes, Prometheus, and Grafana. This is a role where you’ll own it end to end, from the first prototype through launch, iteration, and beyond.

Requirements

5+ years of fullstack development experience
3+ years in TypeScript/Node.js
Experience with a modern frontend framework (React preferred)
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
Comfortable working directly with external partners and customers on requirements gathering, integration, and iterative feature development
MVP mindset: ability 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

Nice To Haves

Experience in fast-paced, high-growth startup environments where you've worn many hats
Track record of prototyping and launching customer-facing products, not just internal tools
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)
