To build and deploy useful, fault tolerant quantum computers.
Role
Who you are
- We have roles focusing on photonic devices, test development, high volume wafer testing, and hardware enablement
- As such, the successful candidate should have demonstrated strong ability in at least one of characterization of passive photonic chips, active photonics measurement, or superconducting device characterization
- Hardware skills are encouraged, including CAD-based design
- The successful candidate must be able to work effectively within a fast paced environment where first time success and operational excellence are critical
- Technical capability: Deep knowledge on at least one area of device and test characterization
- Technical breadth: Able to be effective in hardware, software, and statistics. As a high velocity startup, technical flexibility is key
- Operations: Work with operational stakeholders to make sure test equipment, use cases and plans are completed to allow effective testing on systems, and develop for speed and first time correctness
- Equipment repair and troubleshooting: Hands on ability to fix software, hardware, and electronics issues
- Documentation: Good code and hardware planning and documentation is crucial
- Degree in Engineering or Physics. Advanced degrees welcome
- Experience in Hardware development
- Experience with test system programming, with Python development experience strongly preferred
- Experience working with engineers and technologists in R&D and NPI environments
- Desired: Familiarity with many of the following: computing architectures, semiconductor subsystems, lasers/photonics, switching systems, packaging technologies, advanced testing, systems engineering, or cryogenic systems
- Leadership and Ownership. Ability to work independently with limited direction
- Biased to action: works to get critical work done quickly and well
- Results oriented: make commitments, stay on schedule, update regularly, and deliver
- Attention to detail. Data-driven with high quality work
- Strong organization skills
- Works well in teams
- Excellent verbal and written communication skills with an ability to communicate effectively to a variety of audiences
- Demonstrated interest in PsiQ’s mission and vision for quantum computing, with an ability to contribute in a start-up environment consistent with PsiQ’s values of communication, collaboration, respect, results and challenge
What the job involves
- PsiQ is seeking test engineers for our Test & Measurement (“T&M”) team
- The T&M team is responsible for our functional yield and test platforms: This includes test hardware, software, and applications to support our photonics, electronics, reliability, and yield platforms
- These test platforms are used for characterization, validation, and pre-production tests and interface to a data platform environment to facilitate T&M and adjacent team data reduction, data analysis, and design feedback
- Test engineers work cross-functionally with our Operations, Architects, Photonics, Electronics Teams, Foundry and Packaging Teams, and Systems Teams in developing test requirements, test development plans, and test implementation projects
Our take
Quantum computing will change the world more than any other imminent technological development, and PsiQuantum sits at the forefront of the charge to build the first quantum computer that will actually work.
The company is unique for the scale of their ambitions. Rather than focusing on what they term “intermediate milestones” like building smaller proof of concept systems, PsiQuantum builds the first large-scale, error-corrected computer, using photonics to deliver over 1,000,000 qubits (current quantum machines have yet to cross the 1,000 qubit mark).
There are plenty of companies building quantum computers, including the likes of IBM and Google, but these prototypical machines lack the size to correct errors, making them exponentially less useful than what PsiQuantum aims for. While other companies operate in the same sphere, PsiQuantum is unequivocally a leader in its field, founded by world-class academics and recently securing $1B in funding, making it the largest funding round for a quantum computing startup.
