About Pure
Pure is building the future of rare coin and precious metal trading. We believe collectors and investors deserve financial infrastructure that matches the standards of modern markets. That is why we are creating a new kind of order book marketplace that brings transparency, efficiency, and trust to an industry still rooted in legacy systems.

Started in 2023, Pure is one of the fastest growing marketplaces for tangible assets. We currently process over $45 million in transactions each month and are expanding rapidly. Our mission is to modernize an old industry by combining the reliability of traditional trading systems with the innovation of cutting-edge technology.

What You Will Be Doing:
  • 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.
Who You Are:
  • Have 3+ years of full stack engineering experience (or equivalent), especially in startup or fast-paced environments.
  • Are comfortable leading yourself and others - owning features / systems, guiding teammates, making decisions.
  • Are hands-on: you write and ship code, prototype, fix bugs, and also think about architecture and scalability.
  • 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.
  • 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.
Bonus:
  • 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.

What We Offer:

Flexible work arrangements: Remote, hybrid, or in-office in L.A.
Health coverage & insurance: Medical, dental
Retirement: 401(k) with employer match
Extras & perks: Daily lunches, Wellness stipend

We move fast. We prioritize shipping with quality, reliability, and correctness.
Ownership matters. You will have autonomy and be expected to lead and follow through. If you are excited and can do core things well, even if you do not match every box, apply.
