Company mission
To build and deploy useful, fault tolerant quantum computers.
Role
Who you are
- Master's or Ph.D. Degree or above in Electrical Engineering, Physics or equivalent
- 10 years of relevant experience in product development and release to volume manufacturing leading to multiple successful commercial products
What the job involves
- The mission of PsiQuantum's Principal Hardware Design Engineer role is to support the Electronics team by owning hardware designs integral to the underlying system of the quantum computer
- This engineer will collaborate in cross-functional teams of thermal, mechanical, firmware, optical engineers
- The designs will meet the requirements of the overall system architecture and physical framework of the quantum computer
- Design, create schematics, and oversee PCB layout of analog and digital circuitry consisting of but not limited to high-speed transceivers, 10+ Gbps electrical and optical data links, FPGA's, microcontrollers, clock distribution, power supply filters, inrush current limiters and power distribution
- Ensure robust signal integrity and EMI suppression in all designs
- Design and create test set-ups for testing of electro-optic modules
- Characterize, optimize, and debug analog, digital, and electro-optic circuitry using equipment such as mixed signal & sampling oscilloscopes, vector network analyzers, signal generators, multimeters, DC power supplies
- Develop software to drive measurements
- Analyze data and extract key performance parameters
- Maintain detailed documentation of hardware designs, test results, and design changes
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.
