Sr. Embedded Software Engineer, Residential Vehicle & Robot Charging

The Residential & Robot Charging team owns the full stack of Tesla's home, multi-family, and humanoid-robot charging products (Universal Mobile Connector, Wall Connector, and the Optimus Charger). We build the software that makes charging safe, fast, low-cost and widely accessible.

Our chargers are secure, grid-interactive IoT nodes that must run flawless safety-critical code 24/7, support seamless OTA updates, handle dynamic load management across many units, allow for vehicles to power the home, enable energy billing/reimbursement, integrate with Tesla App, and (soon) charge millions of Optimus robots.

• Collaborate with mobile, backend, and hardware teams to deliver complete features (e.g., PowerShare, scheduled charging, site-level load balancing)
• Drive test automation (unit, SIL, HIL, fault injection) and CI/CD pipelines for firmware
• Provide technical mentorship and set the quality bar for the team

• 5+ years shipping high-reliability embedded firmware for connected devices
• Strong C/C++ skills in resource-constrained and real-time environments (FreeRTOS, Zephyr, bare-metal)
• Proven experience with TCP/IP, TLS, HTTP, WebSockets in embedded systems
• Hands-on experience with EV charging standards (OCPP, ISO 15118, DIN 70121) or robotics preferred
