About us
We hold the key to making quantum technology useful and operate at the highest levels of the emerging quantum sector. Our products are already revolutionizing the way quantum technology is used; From educating the workforce on how quantum computing works with Black Opal, to the industry-first native integration of our performance-management software with IBM Quantum services in November 2023, we are building the global quantum sector and defining the quantum infrastructure software segment. But our work isn’t limited to quantum computing; we go everywhere that quantum goes. In July 2023 our work with Australian Defence delivering software-ruggedized quantum sensing for navigation without GPS was featured in the New York Times.
We base these world-leading commercial outcomes on a foundation of transformational research. We operate the industry’s largest team of experts in quantum control, and push the limits of human capability through our software, hardware, and technical publications in the world’s most prestigious scientific journals.
As a high-growth global quantum startup we’ve raised US $74M since 2017 from investors such as Airbus Ventures, Horizons Ventures, Main Sequence Ventures, Salesforce Ventures, Sierra Ventures, SquarePeg Capital, and others; this includes the world’s largest Series B for any quantum software company, announced in early 2023. Adding to the completion of our new global HQ in Sydney (Australia’s first fully dedicated, commercial quantum technology site), Los Angeles, and Berlin offices, we’ve also recently announced our expansion into the UK to continue to impact the development of quantum technology globally.
We’re led by our values: to be real, to be trusted, to be just, and to be revered. We’ve brought together an inspiring team of world-leading physicists, engineers, product and design specialists (to name a few!) to help us shape the future of quantum technology. And we’re looking for new team members who want to help us change the world.
About the role
As a Senior Back-end Engineer on the Boulder Opal Scale Up team, you will lead the design and development of scalable, high-performance backend systems while playing a key role in managing cloud infrastructure. You will collaborate with cross-functional teams to deliver cutting-edge solutions that power our quantum products, from SDKs to cloud-based offerings. This role is ideal for someone passionate about Back-end engineering and cloud management in a fast-paced, innovative environment.
What you'll be doing:
- Design, develop, and optimize scalable backend services and APIs using Python.
- Build high-efficiency service-to-service communication using modern protocols.
- Assisting in managing AWS cloud infrastructure to ensure optimal performance, scalability, and reliability.

- Implement and enforce best practices for code quality, security, and operational efficiency.
- Troubleshoot, optimize and enhance system performance and reliability.
- Continuously drive improvement in backend and cloud infrastructure through automation and proactive monitoring.
Ideally you'll have:
- 5+ years of experience in backend software development with Python, Rust, or Go.
- Hands-on experience with gRPC or similar frameworks (GraphQL, RESTful) for building high-performance services.
- Deep understanding of distributed systems and microservices architecture.
- Proven experience with cloud providers (AWS, GCP, Azure), and cloud infrastructure management.
- Strong problem-solving skills and proactive approach to finding solutions.
- Familiarity with CI/CD pipelines (e.g. GitHub Actions, CircleCI) and container orchestration tools like Kubernetes.
- Excellent collaboration and communication skills across cross-functional teams.
-
AWS certification (a plus).
It would be fantastic if you have these skills/experience but not essential:
- Experience with infrastructure-as-code tools like Terraform or CloudFormation.
- Familiarity with monitoring tools like Prometheus, Grafana, or AWS CloudWatch.
- Knowledge of database optimization and scaling techniques.
- Experience with Python Web Frameworks such as Django, Flask, or FastAPI.
- Previous experience working in a start-up or scale-up environment.
