The Qira engineering team builds and tests the full system behind this experience, including device software, cloud services, and AI components.
About The Role
We are looking for a Staff Performance Engineerto run hands‑on performance and latency tests for Qira on physical devices in ourChicago office lab. This role focuses on collecting accurate performance measurements, running structured test plans, and reporting results to engineering teams. It is afully on‑site roledue to the need to handle hardware, test stands, and controlled device environments.
Location:On-site in Chicago, IL. This role is hybrid (3 days in office and 2 days remote).
What You'll Do
- Run manual and automated performance and latency tests on Qira 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, Qira versions, and test environments.
- Record, organize, and report performance results to engineering teams in clear, accurate formats.
- Reproduce reported performance issues and validate performance fixes.
