Senior Site Reliability Engineer

About us

Founded in 2017, Q-CTRL has grown to become the global leader in quantum.  We’re using control to solve the hardest problems facing quantum technology, improving hardware performance and accelerating pathways to useful quantum computers and other technologies. As a product-led company, we bring together diverse teams such as product, design, engineering and research to help achieve our mission of making quantum technology useful.  Join us to help shape the quantum future.

As one of the fastest growing companies in the quantum sector, we’ve had a number of key milestones:

- In November 2023, we announced an industry-first partnership with IBM Quantum Services, natively integrating our performance management software with all IBM quantum computers.  Building off of this relationship, in September 2024 we started offering two services via IBM’s new Qiskit Functions Catalog as an inaugural partner.

- Designed and moved our Global HQ offices and lab space into the first purpose-built (and award winning) commercial and research facility for a quantum technology company in Australia.

- Continued to deliver real world outcomes across the quantum sectors, with our work with Australian Defence on software-ruggedized quantum sensing for navigation without GPS, as featured in the New York Times.

- In October 2024, we announced our record breaking expansion of our Series B funding round to USD $113M, with $59M USD of new capital.

- Grew our global presence to include Los Angeles, Berlin, and Oxford - as well as the recently announced office in San Francisco.

From educating the workforce on how quantum computing works, to building the next generation of quantum sensors, to delivering massive performance gains for end-users, it all starts with hiring the right talent. If you want to help us build the Quantum future, read on.
