Senior Full Stack Developer

About This Role

We're looking for a Senior Full Stack Engineer who ships fast, thinks clearly, and solves real problems. No fluff. No red tape. Just strong engineers building software that matters.

What You'll Do

• Own features end-to-end — from backend API design to frontend implementation to production
• Write clean, scalable, maintainable code across the full stack
• Identify and fix performance and reliability bottlenecks in both frontend and backend
• Work closely with product, design, and ops to ship pragmatically
• Make informed technical decisions about when to go deep vs. when to keep it simple

Tech Stack

Backend (Key Focus)

• FastAPI — you'll build APIs with this daily
• Pydantic — data validation and serialization is critical
• Python,go

Frontend

• React, Next.js
• TypeScript
• Zustand, Tailwind CSS

What You Bring

• 8-10+ years of hands-on engineering experience across full stack development
• Strong depth in Python/Go AND TypeScript/JS — not just familiar with both
• Solid experience with FastAPI and Pydantic — you know these tools deeply
• Experience building and scaling production systems — you understand tradeoffs between backend and frontend
• Sharp problem-solving skills — frameworks are tools, not the point
• Clear communicator with low ego, high ownership
• Able to juggle priorities without hand-holding — from database schema design to UI polish

Nice to Have

• Experience with AWS, infra, or performance optimization
• Strong opinions on system design (and the ability to defend them)
• Experience with database optimization and query performance
• Side projects or open-source work you're proud of
• Understanding of both relational and non-relational data patterns
• Familiarity with SQLAlchemy (nice to have, not a blocker)

Why Join Cadence

• Full autonomy — own your projects, make technical decisions
• Remote-first, async-friendly — work from anywhere
• Small team, high trust — no micromanagement
• Speed over bureaucracy — ship features, not meetings
