Fractional Senior Full Stack Engineer

Senior Full Stack Engineer (Part-Time Contract, $85/hr)

This is a 20–30 hour/week contract at $85/hour, fully remote.

GeoVisual Analytics builds custom software and analytics solutions for the fresh produce supply chain and the businesses around it. Our focus is AI implementation and modernization: helping an industry that still runs on spreadsheets and phone calls move to modern, data-driven tools. We're looking for a senior full stack engineer to join us on a contract basis, delivering client work and building out our platform.

The engagement

• 20–30 hours per week
• 3–6 month initial contract, with the intent to extend
• $85/hour
• Fully remote, with flexible hours and time zone

What you'll work on

• Designing, building, and maintaining the frontend and backend of new platforms, from feature development through production
• Leading projects end to end, including new features where the requirements aren't fully defined yet
• Building integrations between our platforms and our clients' cloud and AI infrastructure
• Working with business teams to turn real day-to-day workflows into working software
• Implementing secure authentication, access control, and data governance for sensitive business data
• Shipping with strong testing, CI/CD, deployment, and observability practices
• Iterating on features based on real usage and feedback, balancing speed with reliability

Our stack

• Languages: TypeScript, Node.js, Python
• Frontend: Next.js, React, Tailwind CSS, Radix UI
• Backend: NestJS, FastAPI
• Data: Supabase (Postgres), Firebase (Firestore, Cloud Functions), Drizzle ORM, Typesense, dbt
• Maps, 3D, and ML: Mapbox GL, Turf.js, Three.js, GeoPandas, Rasterio, Shapely, PyTorch, Sentinel Hub
• Monorepo: Turborepo, pnpm/Yarn workspaces
• Hosting and infrastructure: Vercel, Fly.io, Render, Modal, Cloudflare Workers, Docker, GitHub Actions
• Operations: Sentry, LaunchDarkly, Resend
• Testing and quality: Vitest, Jest, pytest, ESLint, Prettier, ruff/mypy
• How we work: Linear, Slack, GitHub

You don't need experience with all of these. Equivalent tools count, and the smaller pieces are quick to learn.

To apply

Send your resume and a few sentences about a project you shipped end to end, including what you built and what you'd do differently. Links to GitHub or a portfolio are welcome.
