Senior Full Stack Engineer

We’re looking for a Senior Full Stack Engineer who loves to build. This role is all about getting things working—fast—and then making them solid.

You’ll be hands-on across the stack, taking defined user journeys and turning them into real, clickable prototypes, then hardening them into reliable, production-ready features. There’s no people management here—just solving problems, writing code, and shipping.

You’ll work closely with your Innovation partner (who’s experimenting with new ideas and patterns) and help bring those ideas into the product in a practical, shippable way. We collaborate remotely, with in-person sessions to whiteboard, pair, and move things forward quickly.

Our Core Tech Stack

Frontend

• React + TypeScript (Vite)
• Storybook

Backend & APIs

• .NET (Minimal APIs)
• TypeScript (Node.js / Express)
• REST and gRPC

Testing

• Playwright (E2E & API)
• Vitest

AI / Process

• Agentic-driven code generation
• Automated workflow validation and refinement

What You’ll Do

• Build end-to-end features across frontend and backend—from idea to demo to production-ready.
• Turn lightweight wireframes and “good enough” requirements into working software.
• Prototype quickly, then clean things up: edge cases, error handling, performance, tests.
• Take AI-generated code and make it production-worthy.
• Plug experimental UI and workflows into our core applications and services.
• Work closely with design and engineering to keep things practical and moving.

What We’re Looking For

• You’re an experienced full stack engineer who likes shipping more than theorizing.
• You’re comfortable working across React + TypeScript and modern backend APIs.
• You enjoy ambiguity and don’t need everything fully specified to get started.
• You use AI tools to move faster—but you know when to step in and clean things up.
• You care about quality, testing, and building things that don’t fall over later.
• You’re self-directed, motivated, and take ownership of what you build.

What Success Looks Like

• Features go from idea to working demo quickly.
• Prototypes turn into stable, production-ready flows.
• Core admin and platform functionality “just works.”
• New ideas don’t stay experimental—they make it into the product.
