Systems Integration Engineer (Field, Quantum Systems)

Develop detailed experimental plans for each cooldown: define measurement scope, sequence, and success criteria prior to cool-down.

Characterise qubits and readout using internal tooling; validate coherence, line yield, and qubit yield against project requirements.

Debug failures and isolate root causes across hardware, fabrication, and design.

Provide remote support to on-site teams as required between deployments.

Validate single- and two-qubit gate performance against specification using standard benchmarking techniques.

Bring up and fine-tune gate calibrations on production devices; identify and resolve systematic error sources affecting 1Q and 2Q fidelity.

Maintain, monitor, and improve Rigetti's automated recalibration system for cloud-deployed processors.

Own deployment workflows for new gate calibrations: test, validate, stage, and release to production with minimal disruption to uptime.

PhD in Physics, Applied Physics, Electrical Engineering, or a related field; or equivalent degree with relevant industry or postdoctoral experience (see track requirements below).

Hands-on experience with superconducting qubit devices.

Proficiency in Python in a scientific or engineering context.

Strong systematic debugging skills: able to isolate failures across the full measurement chain (wiring, electronics, device, software).

Comfort operating in customer-facing and field environments with limited on-site infrastructure support.

Excellent written and verbal communication; able to write clear experimental reports and debrief non-specialists.

Willingness and ability to travel internationally 10–25% of the time.

MS/BS with 3+ years of relevant experience (or PhD).

Experience troubleshooting cryogenic microwave hardware.

Experience calibrating and characterising 1Q and 2Q gates on superconducting qubit devices.

Strong quantitative understanding of gate error sources: decoherence, leakage, control distortion, etc.

Experience writing high-quality code and working through formal code review (Git).

Experience operating and troubleshooting dilution refrigerators.

Knowledge of common qubit failure modes and their signatures (e.g., TLS, flux noise, packaging issues).

Software development experience in a collaborative industrial setting (Git, code review, CI).

Prior experience in a customer-facing or field engineering role.

Experience with automated or scheduled recalibration systems in a production or high-uptime environment.

Familiarity with cloud deployment infrastructure (AWS, Azure, Kubernetes, Docker).

Experience with pulse-level gate optimisation (DRAG, flux pulse shaping, dynamical decoupling).

Experience supporting a rotational on-call or production-support schedule.

As engineering leaders, we value diversity and are committed to building a culture of inclusion to attract and engage innovative thinkers. Our technology, meant to serve all of humanity, cannot succeed if those who built it do not mirror the diversity of the communities we serve. Applications from women, minorities, and other under-represented groups are encouraged.
