About the Job

Requirements

Exceptional C++ programming ability and comfort with assembly when low-level hardware details matter.
Prior industry or research experience in compilers, program analysis, simulators, and/or hardware testing.
Deep experience with compilers, program analysis, cycle-accurate or functional simulators, or hardware verification/testing.
Evidence of ownership of complex systems and ability to bring them to production quality under pressure.
A degree in Engineering or Computer Science, or equivalent experience and evidence of exceptional ability.

Responsibilities

Own and evolve high-fidelity functional simulators for custom SI accelerators, enabling architects and software teams to explore the design space before hardware is available.
Build and harden compiler and hardware-monitoring tooling that turns abstract models into production-grade silicon.
Develop analysis and bug-detection algorithms to identify failures at massive scale and parallelism.
Debug the full stack, including compiler bugs, defective silicon behavior, and microarchitectural corner cases, on systems pushing the limits of parallel compute.
Work across hardware architecture and software, feeding insights into future chip generations to improve reliability, efficiency, and performance.

Job Description

You’re not just writing simulators. You’re building the digital twin of the silicon that will run the most important real-world SI on Earth — and eventually beyond it. Tesla’s next-generation inference chips (SI6 and Dojo 3) are being designed to extract the maximum usable intelligence from every square millimeter of silicon. Your job is to make sure that silicon is correct, fast, and reliable before the first wafer ever comes back. You will create the pre-silicon development environment that lets the entire SI hardware and software stack move at the speed of first principles instead of the speed of foundry cycles.

Job Responsibilities

Own and evolve high-fidelity functional simulators for our custom SI accelerators — the tools that let architects and software teams explore the design space while the hardware is still electrons on a screen
Build and harden the compiler and hardware-monitoring tooling that turns abstract models into production-grade silicon
Invent smarter analysis and bug-detection algorithms that catch the subtle, nasty failures that only appear at massive scale and parallelism
Debug the full stack — compiler bugs, defective silicon behavior, microarchitectural corner cases — on systems that push the limits of what parallel compute can do
Sit at the intersection of hardware architecture and software, constantly feeding real insights back into the next generation of chips so they become more reliable, more efficient, and more powerful

Job Requirements

Prior industry or research experience in compilers, program analysis, simulators, and/or hardware testing
Deep experience with compilers, program analysis, cycle-accurate or functional simulators, or hardware verification/testing
Evidence that you can take ownership of complex systems and drive them to production quality under real pressure
Degree in Engineering, Computer Science, or equivalent in experience and evidence of exceptional ability

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.
