Tech Lead (Spanish Fluent)
Location: Remote, with travel to Mexico as needed | Type: Contract | Experience: Senior to Lead | Pay: Up to $90/hr

We're hiring three Tech Leads to own the frontend, backend, and platform layers of an enterprise calculation platform being built for a client with operations in Mexico. The system is a React single-page app sitting on a Django backend, with FastAPI engine services handling the heavy calculation and explosion work, all running on Azure.

The client teams you work with are in Mexico, so the day-to-day happens in Spanish: standups, architecture debates, documentation, and the occasional trip onsite.

If you're looking for a title where you write architecture docs and hand them off, it isn't this one. Own the technical direction for one layer of the platform, either the React SPA, the Django backend, or the FastAPI engine services, and stay hands on in it
