Our client is a US-based technology company focused on driving the next generation of vehicle and mobile technologies.
For them, we are hiring a Senior Full Stack Engineer (UI-Leaning) to join a Growth-focused engineering team responsible for scaling a customer-facing membership and enrollment platform.
This role is full-stack but leans toward React and frontend implementation, while still requiring backend capability and production ownership.
This is not a maintenance role; the platform is being expanded to support multiple enterprise clients, and the team is investing heavily in scalability and performance.
If you're more of a Backend-heavy kind of fullstacker, strong in Python, FastAPI, MongoDB, and AWS, and you also live in Latin America, please check another role we have here - https://virtasant.teamtailor.com/jobs/7194241-senior-full-stack-engineer-backend-heavy-latam-est-hours
