About the Job

Requirements

Currently pursuing a degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
Experience writing software in Python and/or Go, with the ability to read others’ code and propose or implement fixes.
Coursework or internship experience in manufacturing, testing, or embedded systems, and interest in working alongside operators rather than only at a lab bench.
Ability to debug embedded products using CAN or similar buses, serial/Linux logs, and electrical test equipment such as oscilloscopes, power supplies, and loads.
Working knowledge of, or strong interest in, power electronics, battery systems, or high-voltage energy products, and understanding what a production test proves.
Ability to communicate clearly, acknowledge uncertainty, take ownership of assignments when the production line is waiting, and work on-site in Buffalo, NY. Relocation to Buffalo is required for the internship.

Responsibilities

Write and debug Go and Python software used to test Energy products on the factory line, including station automation and tester integration.
Help author in-process and end-of-line test specifications so each step has coverage that matches the hardware, firmware, and process running.
Analyze production test data for yield, cycle time, and failure signatures, then drive fixes into station software, process, or firmware.
Debug failing units on the floor using CAN analyzers, Linux and device logs, oscilloscopes, power supplies, and loads.
Help bring up production-line testers and off-line end-of-line regression testers that validate firmware before production; support flashing, provisioning, and firmware releases through new product introduction and sustaining engineering.

About the Company

Tesla

Makes electric cars, robotaxis and grid batteries

Tesla makes electric cars and batteries that store power for homes and utilities, and it develops self-driving software and humanoid robots. In 2023, its Model Y became the first electric vehicle to rank as the world's best-selling car. Buyers order the Model 3 sedan, Model Y SUV, or Cybertruck pickup directly from Tesla instead of through dealers, and they charge on its Supercharger fast-charging network. It also sells Megapack and Powerwall batteries, runs a robotaxi service, and charges drivers a monthly fee for self-driving software that still needs their supervision. Tesla was founded in 2003, with Elon Musk as its lead early investor and a recognized co-founder, and it is based in Austin, Texas.
