Performance Engineer

No H1 or C2C. Must be Permanent Resident/Green Card or US Citizen We are looking for a Performance Engineer to run hands‑on performance and latency tests on physical devices in our. This role focuses on collecting accurate performance measurements, running structured test plans, and reporting results to engineering teams.

It is a fully on ‑ site role due to the need to handle hardware, test stands, and controlled device environments. What You Will Do Run manual and automated performance and latency tests on devices (PCs, phones, tablets). Execute test plans for cold‑start latency, model response times, CPU/GPU load, memory use, battery impact, network conditions, and cross‑device performance.

Use monitoring tools, logs, and profiling utilities to collect reliable data from devices. Set up, configure, and maintain device test stations, including OS builds, and test environments. Record, organize, and report performance results to engineering teams in clear, accurate formats.

Reproduce reported performance issues and validate performance fixes. Follow structured processes for device flashing, test updates, and controlled testing conditions. Experience running performance or latency tests on software, mobile devices, or hardware systems.

Basic understanding of Android, Windows, or device ‑ level performance tools . Ability to follow structured test plans and accurately capture numerical results. Comfortable working hands‑on with devices, cables, builds, and lab equipment.

Familiar with basic logs, metrics, and debugging steps. Strong attention to detail and clear communication skills. Ability to work on ‑ site in Chicago (no remote option).

Preferred Qualifications Experience with mobile or PC hardware performance testing. Exposure to AI/ML workloads or latency‑sensitive applications. Familiarity with device flashing, ADB, performance profilers, or network throttling tools.

Experience working in an engineering lab or device test environment. #J-18808-Ljbffr
