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

The Q-CTRL Infrastructure team is the backbone of the Q-CTRL Platform and all of the products that run on it. The mission of our team is to ensure that all of Q-CTRL’s infrastructure remains available, performant, reliable, scalable, and secure so that Q-CTRL can continue to deliver its revolutionary quantum technology.

As a Senior Cloud Platform Engineer at Q-CTRL, you will be playing a critical role in our team building the Q-CTRL Platform, a Kubernetes-based platform containing a variety of different workloads, including quantum modeling and GPU-accelerated workloads. You will help ensure that our end-to-end processes - development, testing, deployment, and maintenance - are as optimized and as code-driven as possible.

You will be joining an established team offering you support, coaching, and mentorship. You will work closely with all teams at Q-CTRL to advocate for a culture and practice of quality and continuous improvement and leading by example.

What you'll be doing:

- Becoming intimately familiar with our software stack, including but not limited to: Providing insight from your past knowledge and integrating that into our overall platform architecture, making changes to application code when needed, and ensuring we use the best technologies possible to achieve our platform goals.
- Ensuring that Q-CTRL stays current with industry best practices for operating in the cloud and proactively apply them, be a passionate advocate of DevOps culture, and be an active contributor towards innovating on and improving on our software engineering practices.
- Developing toolchain support: CI/CD pipelines, ephemeral test environments, vulnerability scanning, and automated infrastructure-as-code deployment tooling.
- Helping ensure our applications are scalable, highly available and cloud-agnostic. We target multiple public clouds, we also may provision private infrastructure for select clients.
- Being consistently learning, as staying on top of your game is part of your job.

Ideally you'll have:

- 5+ years of industry experience in Platform Engineering, Site Reliability Engineering, or equivalent.
- Worked with Kubernetes in a production environment before and are intimately familiar with all the things needed to create a Kubernetes cluster in a production scenario.
- Expert knowledge about public clouds such as AWS or GCP to know how to configure them to current best practices as infrastructure-as-code and how that applies to a Kubernetes environment.
- Worked with a variety of Linux distributions and can troubleshoot common problems.
- Proficiency in software development and programming and can quickly understand what an application is doing by looking at its codebase, sometimes with minimal information at hand. We primarily work with applications that use Go and Python.
- Excellent written and verbal communication skills, with the ability to present complex technical concepts to both technical and non-technical audiences.
- A keen eye that identifies areas for improvement and takes initiative in implementing new technologies and solutions while building things the right way.

It would be fantastic if you have these skills/experience but not essential:

- Relevant Kubernetes certifications such as CKA, CKAD, or CKS.
- Relevant public cloud certifications such as AWS SAA/SAP or GCP ACE/PCA.
- Familiarity with the CNCF and its various projects.
- Experience using GitOps tools such as Argo CD or Flux CD.
