About us
Founded in 2017, Q-CTRL has grown to become the global leader in quantum control infrastructure software. 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. We believe that working in deep tech domains like quantum provides an opportunity to upskill whilst applying existing knowledge and practices to new markets.
As one of the fastest growing companies in the quantum sector, we’ve had a number of key milestones:
- In October 2024, we announced our record breaking expansion of our Series B funding round to USD $113M, with $59M USD of new capital.
- 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.
- Grew our global presence in Los Angeles and Berlin, and expansion into the UK, recently opening up a new office in Oxford.
- 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.
From educating the workforce on how quantum computing works, and 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.
About the role
We are seeking a Senior Software Engineer, Quantum Control to help advance our software-enabled, quantum design and control products. Reporting to the engineering manager, the role will bridge the gap between our Research and Engineering teams. It will provide software design expertise to our exceptional quantum researchers, developing solutions across an ever expanding number of business cases at the forefront of the quantum industry.
What you'll be doing:
- Pairing with quantum physics researchers and experimentalists, you will utilize exceptional software design skills in both client and back-end development to efficiently support their software needs, allowing them to focus on innovation.
- When not pairing with researchers, you will be implementing product features that promote architecture reuse across business use cases.
- You will troubleshoot and address software issues independently to maintain high responsiveness to customer needs.
- Key contributions to designing, developing, and optimising scalable back-end architectures, realised by a number of services and APIs.
- Collaborate with experts from other functions (product, design, infrastructure) to deliver integrated, end-to-end solutions.
- Continuously maintain and ideally raise the bar on code quality, security, and operational efficiency.
- Consistently demonstrate your passion for quantum computing and innovation, willing and able to quickly learn and immerse yourself if you joined without a physics or quantum background.
Ideally you'll have:
- Advanced degree (PhD or MSc preferred) in Physics, Computer Science, Engineering, or a related field.
- Proficiency in programming languages such as Python, C++, or Rust.
- Strong problem-solving skills and the ability to work independently.
- Demonstrated ability to collaborate across research and engineering teams.
- Experience in developing frameworks or tools for quantum-related solutions, ideally hardware calibration.
- Proven ability to mentor junior team members and accelerate their contributions.
- Excellent collaboration and communication skills with the ability to work across cross-functional and agile teams.
It would be fantastic if you have these skills/experience but not essential:
- Experience with quantum hardware control systems.
- Strong understanding of quantum physics and quantum computing principles.
- Experience with Python Web Frameworks such as Django, Flask, or FastAPI.
- Experience with infrastructure tools (Kubernetes, Terraform/CloudFormation, Prometheus, Grafana).
- API design using gRPC or similar frameworks (GraphQL, RESTful).
- A track record building distributed systems and microservices architecture.
- Previous experience working in a start-up or scale-up environment.
