## About the Role

* 5+ years building production backend services in .NET/C#, Python, or Go - with a willingness to work primarily in C#
 * Working React and TypeScript experience; comfortable owning a feature's UI, not just its API
 * Solid SQL: can design a table, read an execution plan, and explain why a query got slow
 * Testing habits and comfort with Git-based review workflows
 * CS fundamentals - data structures and algorithms you can actually reason about, not recite
 * Integrating LLM APIs (Azure OpenAI, Claude, or similar) into production backend services

## Description

The Payroll System is the internal platform Tesla's payroll operations teams use to run pay cycles, investigate discrepancies, and satisfy audit and SOX obligations. We build the tooling that a real, named group of people opens every morning - short feedback loops, high correctness bar, and no ambiguity about whether the thing we shipped helped.
What You'll Do

 * Build and ship features end to end - schema and migration, API, and UI - rather than throwing work over a wall
 * Design RESTful APIs in .NET (C#) following our controller to service to repository layering, with dependency injection throughout
 * Build data-dense React interfaces in TypeScript: AG-Grid views, TDS components, Jotai and React Query for state and server data
 * Work on audit workflows, findings triage, and security group management - features with compliance consequences, where "mostly right" isn't right
 * Write unit and integration tests alongside the code (see test/ - unit and integration suites are part of the definition of done, not a follow-up ticket)
 * Participate in code review, both directions
