You’ll help decide what to build, make technical decisions, and stay responsible for how your work performs after launch. You’ll work directly with operations, customer support, compliance, and partners to understand their needs and turn them into working software. What You’ll Do Take ownership of products and services from the initial idea through development, launch, and ongoing improvements. Build customer-facing tools for vault accounts, asset management, shipments, and transfers with TypeScript, React, and Next.js.

Design and maintain backend systems for asset intake, verification, inventory, storage, and shipping. Be responsible for keeping asset ownership records, custody history, and movement accurate and traceable. Work directly with warehouse and logistics teams to improve how assets are received, authenticated, stored, and fulfilled. Build and maintain APIs, webhooks, and integrations that marketplaces, financial institutions, and other partners depend on.

Identify gaps in internal tools with Customer Support and Operations, and carry improvements through to completion. Work with Compliance and Risk to implement identity verification, permissions, and custody controls. Use customer feedback and operational data to set priorities and measure whether your changes solve the problem. Make technical decisions across the stack and take responsibility for reliability, maintenance, and delivery.

Who You Are You have 3+ years of experience building software products, ideally at a startup. You’re comfortable owning a product area, deciding what needs attention, and seeing work through without waiting for a detailed specification. You have strong experience with TypeScript, React, and Next.js. You’ve built backend APIs and services with Node.js or a similar stack, using PostgreSQL. You enjoy understanding how people work and building software that makes their jobs easier.

You communicate clearly with engineers, operations teams, customer support, and business partners. You take responsibility for what you ship, follow up on how it’s used, and address problems when they come up. Bonus Experience building logistics, warehouse management, inventory, or fulfillment systems.
