What To Expect
The Tesla AI Hardware team is at the forefront of revolutionizing artificial intelligence through cutting-edge hardware innovation. Comprising brilliant engineers and visionaries, the team designs and develops advanced AI inference chips tailored to accelerate Tesla’s machine learning capabilities. A key part of this effort is Dojo, Tesla's custom supercomputer system built to efficiently train massive neural networks on vast video data from the fleet. The work of Tesla's AI Hardware team powers the neural networks behind Full Self-Driving (FSD), and Tesla humanoid robot, Optimus, pushing the boundaries of computational efficiency and performance. By creating custom silicon and optimized architectures, the team ensures Tesla remains a leader in AI-driven automotive and energy solutions, shaping a future where intelligent machines enhance human life.
Join Tesla’s elite AI Hardware team and become a driving force behind the next generation of autonomous intelligence. In this high-impact role, you will own performance verification of next-generation NPUs, stress-testing and correlating real ML models and handwritten kernels all the way down to silicon behavior. This is hands-on, deep-dive work that blends kernel development, compiler integration, and rigorous verification to ensure our NPUs deliver groundbreaking efficiency, throughput, and determinism. You’ll write kernels destined for the ML compiler team while relentlessly validating performance across the full stack — helping power Tesla’s Full Self-Driving and Optimus platforms at the absolute edge of what’s possible.
What You'll Do
Own end-to-end performance verification of Tesla’s custom NPUs, ensuring real ML workloads and handwritten kernels meet aggressive power, latency, utilization, and throughput targets
Write, optimize, and verify high-performance kernels for critical ML operators, with many kernels directly integrated and consumed by the ML compiler team
Develop advanced verification suites and correlation methodologies that map high-level ML models through custom kernels down to actual NPU hardware behavior
Collaborate closely with ML compiler engineers, and hardware architects to translate model requirements into optimized kernels and validated hardware performance
Debug complex performance discrepancies across simulation, emulation, FPGA, and post-silicon environments — root-causing issues at the intersection of model, kernel, compiler, and NPU microarchitecture
Build automated regression frameworks, performance dashboards, and correlation tools that accelerate verification cycles and provide real-time visibility into NPU health
Perform deep analysis on key metrics (utilization, bandwidth, latency, power) and establish iron-clad correlation between pre-silicon predictions and real silicon measurements
Document and present verification findings, correlation results, and optimization breakthroughs to influence future NPU roadmaps and Tesla’s AI silicon strategy
What You'll Bring
Degree in Engineering, Electrical Engineering, Computer Science, or related field or equivalent experience
1+ years of intense industry experience in performance verification of NPUs, AI accelerators, or ML hardware
Strong track record writing, optimizing, and verifying high-performance kernels targeted at NPUs or similar tensor-core architectures, with direct experience supplying kernels to ML compiler teams
Deep expertise correlating ML model behavior → kernel execution → compiler integration → NPU hardware across the full verification stack (RTL simulation, emulation, and post-silicon)
Mastery of Python and C++ for building high-performance verification tools, automation frameworks, kernel development, and analysis pipelines
Solid understanding of NPU microarchitecture, memory hierarchies, dataflow scheduling, on-chip interconnects, parallel computing principles, and ML compiler flows
Kernel writing and ML compiler experience is a plus
Exceptional debugging skills with a proven ability to resolve the toughest NPU performance bottlenecks under tight deadlines
Thrives in a fast-paced, ownership-driven, small-team environment with outstanding technical communication skills
Benefits
Compensation and Benefits
Along with competitive pay, as a full-time Tesla employee, you are eligible for the following benefits at day 1 of hire:
