Who You Are:

3–8 years of fullstack experience building production-grade web applications
Expert in TypeScript/React with strong frontend fundamentals and attention to UI/UX
Solid backend experience: APIs, databases, auth, and scalable architecture
Product-minded: you understand business outcomes, user needs, and technical tradeoffs
Ownership DNA: led projects, made technical decisions, and been accountable for outcomes
Bonus: experience in regulated industries or designing flows/mockups in Figma

Responsibilities:

Build user-facing web applications that simplify complex workflows for professional users
Own the full stack: design APIs, optimize queries, implement frontend interactions, and debug production issues
Set technical standards for code quality, design systems, testing, and developer workflows
Collaborate with domain experts to translate requirements into intuitive, reliable software
Balance speed and craft: ship fast but maintain high-quality, maintainable code
Mentor future engineers as the team scales and define the engineering playbook

Tech Stack & Tools:

Frontend: TypeScript, React
Backend: Node.js, Python, SQL/NoSQL databases, API design
Product Tools: Figma or equivalent for mockups
Additional bonus: experience with technical SaaS, regulated industries, or complex workflow automation

Why This Matters:

The software you build will be used by professionals managing critical, safety-sensitive infrastructure. Your work directly impacts efficiency, reliability, and safety, helping them execute workflows faster, with confidence, and at scale.

This is a high-impact, ownership-first role at a startup where your decisions shape both the product and the engineering culture.
