Software Engineer, HR Operations & Systems

Tesla’s HR Operations & Systems team builds the internal technology that powers payroll operations day to day. In this role, you’ll work on end-to-end feature development for Tesla’s Payroll System, supporting pay cycles, discrepancy investigation, and audit and SOX obligations. You’ll ship changes across backend services, REST APIs, and data-rich user interfaces, with a strong focus on correctness, testing, and security where “mostly right” is not acceptable.

What you’ll do

• Deliver features from start to finish, including schema and migration, REST API work, and UI updates, rather than handing off tasks between teams
• Design RESTful APIs in .NET (C#) using a layering approach from controller to service to repository, with dependency injection throughout
• Build data-dense React interfaces in TypeScript, including AG-Grid views and TDS components, using Jotai and React Query for state and server data
• Work on audit workflows such as findings triage and security group management, developing capabilities with compliance consequences
• Write unit and integration tests alongside the code (test/ unit and integration suites are part of the definition of done)
• Participate in code review in both directions

What you’ll bring

• 5+ years building production backend services in .NET/C#, Python, or Go, with willingness to work primarily in C#
• Working experience with React and TypeScript, with comfort owning a feature’s UI in addition to its API
• Strong SQL skills, including designing tables, reading an execution plan, and explaining why a query became slow
• Testing habits and comfort working with Git-based review workflows
• CS fundamentals such as data structures and algorithms you can reason about
• Experience integrating LLM APIs (including Azure OpenAI, Claude, or similar) into production backend services
• Exposure to RAG pipelines, vector databases, or structured prompt engineering
• Ability to ship AI-assisted features in an enterprise application
