About the team
At Q-CTRL, Quantum Computing Engineering is a global team of software engineers and infrastructure experts, combining deep technical expertise with a startup mindset to deliver real impact through software innovation. Our work is underpinned by robust standards, and by embracing the three virtues. Our team excels in areas across back-end, front-end, machine learning, and platform engineering.
We transform Q-CTRL’s world-leading technological breakthroughs into commercial software products with applications across defense, research, and industry. We work closely with Product, Design, and Research teams to accelerate the path to quantum advantage worldwide.
About the role
The Q-CTRL Platform has grown rapidly; from a single product running as a single container to a growing list of products in a highly distributed Kubernetes environment. New and exciting customer opportunities are seeing this stack evolve further; including on-premise and hybrid architectures as well as full-stack solutions embedded on the edge.
Q-CTRL faces a diverse and dynamic security landscape which is shaped by industry, customer, and compliance requirements. The Q-CTRL Infrastructure team is expanding to bring on a Security Engineer with a focus on designing, implementing, and maintaining systems in order to fulfil the Q-CTRL Security Objectives.
What you'll be doing:
- Reporting to the Engineering Manager for Infrastructure, you’ll play a hands-on role in ensuring we deliver the highest security standards for Q-CTRL products and maintain the trust our customers place in us.
- Strengthening the security of the Q-CTRL Platform through contribution to key systems like Kubernetes clusters, cloud networking, Zero Trust Network architectures, and firewalls.
- Consistently upholding compliance with security frameworks through the improvement of systems and processes. This includes access control mechanisms, data management and security guardrails.
- Applying knowledge in Forensics & Incident Response to triage incidents and raise alerts based on observability.
- Maintaining our vulnerability management systems in order to improve key security metrics for Q-CTRL.
- Other duties within the Employee's skills and experience, or with reasonable training.
Ideally you'll have:
- Previous experience as DevSecOps or DevOps with security engineering focus.
- Knowledge of operating Kubernetes in production; managing helm charts/operators, security configurations and hardening workloads.
- Hands-on cloud networking experience, including knowledge of ZTNA & secure network access.
- Experience with firewall technologies, both at a cloud and application level.
It would be fantastic if you have these skills/experience but not essential:
- Experience maintaining a vulnerability management system, including delivery of threat modelling and risk register engagements.
- Experience with Kubernetes runtime security tooling such as Falco or Sysdig.
- Security/Kubernetes certifications, for example, Certified Kubernetes Security Specialist or Offensive Security Certified Professional (OSCP).
- Red teaming experience, particularly in regards to cloud or AWS environments.
- Experience with Kubernetes runtime security tooling such as Falco or Sysdig.
- Experience using open-source observability tooling such as OpenTelemetry and Grafana to set up security alerting and alarms. Experience working with SIEM/SOC tooling such as Splunk or Microsoft Sentinel to identify and triage security alerts.
