Senior Full Stack Developer, Remote (Full-Time)

Location: Remote
Type: Full-Time
Industry: Oil & Commodities | Education & Advisory

We're building the infrastructure that powers how businesses trade globally. Think of us as the modern backbone for B2B commerce - a marketplace platform connecting buyers and suppliers across industries, streamlining everything from sourcing to payments. We're a small, fast-moving team where your work ships to real users and your decisions shape the product.

We're looking for a Full-Stack Engineer to own and evolve our core platform. This isn't a ticket factory gig - you'll have real autonomy over architecture decisions, ship features end-to-end, and directly impact how thousands of businesses discover and trade with each other.
You'll be working on a production codebase with a modern stack, taking it from early-stage to scale. You'll have a meaningful voice in technical direction and product decisions.

Building and scaling a multi-tenant B2B marketplace (RFQ workflows, quotation management, order processing)
Payment infrastructure (gateway integrations, subscription billing, webhook processing)
Admin tooling and platform-wide role-based access control (RBAC)
Performance optimization as we grow from hundreds to thousands of active companies
Writing tests and establishing engineering standards that scale with the team

Claude Code, Cursor, Turborepo, Vitest, react-email + Resend

5+ years of production TypeScript experience - and we mean real TypeScript. AI-augmented development workflow - you use tools like Claude Code, Cursor, or similar AI assistants daily to write, refactor, and debug code. You stay current with emerging AI/LLM trends and actively look for ways to leverage them to ship faster. But you don't blindly push whatever the model spits out - you review, understand, and refine AI-generated code with the same rigor you'd apply to any PR.

• js / React experience - App Router, Server Components, server actions, streaming, caching strategies. Solid backend fundamentals - you can design a database schema, write efficient queries and think about indexing.
• tRPC or similar end-to-end typesafe API experience - you understand the value of shared types between client and server and you actively protect that contract.
• PostgreSQL + Prisma (or similar ORM) - schema design, migrations, relations, performance.
• Security-first mindset - input validation, auth middleware, webhook verification, rate limiting, CSRF, XSS prevention. Testing discipline - you write tests. Integration tests, unit tests. AWS services - S3, CloudFront, presigned URLs, IAM policies

DevOps basics - CI/CD pipelines, Railway.com deployment, environment management
You won't be waiting for three approvals to merge a PR.
Remote-first - work from wherever you're most productive.
Async communication (Slack), with syncs when they actually matter.
We ship fast but we don't ship broken. Quality velocity.
AI-Native Engineering Culture
We believe the best engineers in 2026 don't just write code - they leverage AI to ship faster and smarter. We're looking for someone who actively uses AI-powered development tools like Claude Code , Cursor , and similar assistants as a core part of their workflow. You stay on top of emerging trends in AI-assisted development, you know how to prompt effectively, and you use these tools to write, refactor, and debug the majority of your code.
