Senior Rf Engineer - Electromagnetic Design & Simulation

We are looking for a
Senior RF Engineer
to join our hardware team and own the
electromagnetic design, simulation, and validation of on-chip and chip-scale RF structures
that deliver control signals to quantum devices operating at cryogenic temperatures.
In this role, you will drive measurable improvements in
RF performance and power efficiency, taking designs from first-principles analysis through simulation, fabrication, and cryogenic measurement. This position is ideal for an engineer who enjoys
hands-on EM design, thrives on hard physics problems, and wants to work closely with device, fabrication, packaging, and systems teams.
Application Deadline: November 30, 2026
Department: Hardware Engineering
Employment Type: Full Time
Location: British Columbia, Canada (Hybrid)
Workplace type: Hybrid
Compensation: CA$117,000 - CA$161,000 / year
WHAT WE NEED YOU TO DO
Design and optimize
on-chip and chip-scale RF structures, including transmission lines, resonators, and passive coupling structures
Perform
full-wave EM modeling
(HFSS / CST / COMSOL or similar), including near-field analysis of fields delivered to target devices
Improve
RF power efficiency
of control structures, balancing performance against fabrication constraints and yield
Evaluate alternative architectures and
heat-load tradeoffs
at the chip, package, and cryogenic system level
Own
simulation-to-measurement correlation, including cryogenic characterization, and iterate designs accordingly
Support impedance control, matching, and RF loss analysis at the chip and package level
Lead design reviews and produce clear technical documentation
WHAT YOU BRING TO OUR TEAM
M.Sc. or Ph.D. in Electrical Engineering, Physics, or related field with ~5+ years of RF or EM design experience (or B.Sc. with equivalent industry experience)
Strong fundamentals in
electromagnetics, transmission line theory, and impedance matching
Deep hands-on experience with
full-wave EM simulation
(e.G., Ansys HFSS, CST, COMSOL)
Experience designing
RF structures on silicon, interposers, or thin-film substrates
Hands-on
RF measurement and characterization
(VNA, spectrum analyzer, S-parameter de-embedding)
Proven track record
correlating simulation with measurement
and closing the gap through design iteration
Scripting in
Python or MATLAB
for simulation automation and data analysis
Strong written and verbal communication skills
An exceptional candidate will bring:
Experience with
cryogenic or low-temperature RF systems
Familiarity with
superconducting or low-loss thin films
and multilayer substrates
Experience with
quantum devices
or spin/qubit control hardware
Awareness of
microfabrication processes
and design-for-manufacturability
Exposure to startup or research-driven environments
WHY YOU SHOULD WORK WITH US
Get involved with a quantum startup company set to redefine computing
Work closely with some of the brightest innovators in quantum technologies
Enjoy a fast-paced and fun environment where you can try new things while solving innovative challenges every day
Inclusive company culture
Competitive salary, benefits (including life insurance, extended health, dental, long term disability, and a flexible spending account), and potential upside
