Requirements
- Strong front-end experience with TypeScript + Next.js, good eye for UX / UI, performance, accessibility.
- Strong backend experience: Node.js (or similar), working with PostgreSQL, comfortable with designing schema, writing efficient queries, handling transactions and consistency.
- Experience building marketplaces, matching engines, or financial or trading systems.
- Experience working with design systems, component libraries, or UI frameworks.
- Experience with scaling backend services, optimization, monitoring, observability.
- Have 3+ years of full stack engineering experience (or equivalent), especially in startup or fast-paced environments.
- Are hands-on: you write and ship code, prototype, fix bugs, and also think about architecture and scalability.
Responsibilities
- Lead and own critical features and subsystems end-to-end - from design through to deployment. You will make key technical decisions, set priorities, and deliver fast without sacrificing quality.
- Build, maintain, and scale our marketplace backend including order matching / order-book logic with concurrency, correctness, and speed in mind; transaction flows, payments, reconciliation; ensuring data integrity, auditability, resilience.
- Build and refine our frontend / UI/UX using TypeScript + Next.js: translate designer UX flows into high quality components; optimize performance (SSR vs client side, code splitting, lazy loading, etc.).
- Work deeply with PostgreSQL: data modeling, query optimization, indexing, schema design, ensuring performance as data and load grow.
- Develop and improve internal tools (“Nimbus”) for accounting, logistics, operations dashboards, fraud detection, monitoring, etc.
- Lead small teams or mentor other developers: provide code reviews, help unblock teammates, set best practices.
- Drive process improvements, technical architecture, testing strategy, observability. Be hands-on in incidents or urgent problems.
Other
- Are comfortable leading yourself and others - owning features / systems, guiding teammates, making decisions.
- Excellent problem solver: you understand trade-offs between speed, maintainability, architecture, and are pragmatic.
- Good communicator: able to translate business / operations / design needs into technical work, and explain trade-offs.
- Self-driven, independent: you do not need constant supervision; you push things forward, and also know when to ask for feedback.
- Flexible work arrangements: Remote, hybrid, or in-office in L.A.
