Work to Be Done Instead of a list of requirements, we want to give you a directional look into the first 30, 90, and 180 days on the job.
We are a startup, so the pace is fast and the specific work will change. You need to be okay with that.
If you think this is something you can handle, we will be excited to speak with you.
Our team is distributed, with a hub in New York City. For this role, we are open to candidates in the United States.
First 30 Days: Ship features end-to-end
Ramp on our full‑stack architecture: backend services, frontend applications, APIs, and data flows
Ship a small feature end‑to‑end: backend endpoint, frontend UI, and database schema change
Fix bugs across the stack and improve test coverage for the code you touch
Outcomes
Multiple features or bug fixes shipped to production with quality
You understand how data flows from frontend to backend to database
You can navigate our codebase and development workflow confidently
By 90 Days: Own features and raise the bar
Take ownership of a feature area: user dashboard, transaction flows, admin tools, or API integrations
Lead a medium‑scope project: building a new workflow, integrating a third‑party service, or redesigning a key user experience
Improve system quality with better error handling, validation, observability, and user feedback
Outcomes
A delivered feature that improves user experience or enables new business capabilities
You're a go‑to person for your feature area
Measurable improvements in reliability, performance, or user satisfaction
By 180 Days: Drive product impact
Lead a cross‑functional initiative: new product capability, platform redesign, or major integration
Shape technical direction with design docs, architecture proposals, and mentoring team members
Partner with product, design, and compliance teams to make pragmatic tradeoffs on user experience, performance, and regulatory requirements
Outcomes
A multi‑sprint delivery that unlocks significant user or business value
Clear before/after improvements in user metrics, system performance, or developer velocity
Patterns and components that enable the team to ship faster and better
Some Problems You Might Work On
Building secure, performant APIs for stablecoin issuance, custody, and transfers
Creating intuitive user interfaces for complex financial workflows with real‑time updates and clear error handling
Implementing transaction monitoring dashboards with filtering, sorting, and export capabilities
Designing and building admin tools for compliance, user management, and operational support
Integrating third‑party payment rails, banking APIs, and blockchain networks
Optimizing database queries and API responses for sub‑second latency at scale
Building robust form validation, authentication flows, and permission systems
Implementing real‑time notifications and status updates across frontend and backend
Our Typical Stack

Backend: Go microservices with gRPC and REST APIs
Frontend: React, Next.js, TypeScript
BFF Layer: GraphQL and tRPC for backend‑for‑frontend services
Data: Postgres (RDS), Redis, Kafka, Snowflake
Workflow Management: Temporal
