## About the Role

* BS in Electrical Engineering, Computer Science, Physics, or related field with 8+ years of relevant experience (MS with 6+ years, or PhD with 3+ years).
 * Strong Python skills, including asynchronous programming.
 * Hands-on experience building automated test/measurement software with instrument control (SCPI/VISA/GPIB).
 * Working knowledge of electrical, optical, or electro-optical measurement concepts.
 * Experience debugging distributed or fleet-scale systems.
 * Comfortable working at the boundary between software and hardware.
 * Experience with photonics, quantum hardware, or semiconductor/wafer-level test.
 * Familiarity with test data platforms and pipelines

## Description

As an integral part of the team developing a photonic quantum computer, the Staff Test Software Engineer will own the software that drives automated testing, calibration, and data acquisition across our fleet of electro-optical test stations including the sequencing, measurement, and instrument-control code that runs on the test stations built by our hardware test automation team., * Own and extend the test-sequencing software (measurement methods, sequencer logic, instrument drivers) used across the electro-optical test fleet, from prototype through production scale.

 * Design and implement automated measurement methods for electrical, optical, and electro-optical characterization (e.g. spectrum sweeps, IV sweeps, automated optical alignment) across multi-instrument control chains.
 * Build and maintain instrument control layers (SCPI/VISA-based drivers) for lab and production instrumentation.
 * Diagnose and fix fleet-wide test-sequencing issues throughput regressions, alignment/movement bugs, timing anomalies from logs, dashboards, and measurement data.
 * Design failure handling so real hardware/measurement failures surface clearly instead of shipping bad data silently.
 * Partner with the hardware test automation team to translate new test station designs into automated test and calibration procedures.
