Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.
The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!
We're a diverse team of 250+ brilliant minds from over 35 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!
About the Mission
As Alice & Bob scales from research breakthroughs to industrial-grade quantum systems, protecting the integrity of our infrastructure, our applications, and the intellectual property behind years of R&D becomes mission-critical. Security is a core enabler of how fast and how safely we can move.
About the Role
We're looking for a Senior Security Engineer to help secure and evolve our IT infrastructure and applications, spanning everything from corporate identity systems to the security of our quantum R&D labs. You'll own key security initiatives end to end, set standards and best practices across the company, and mentor junior engineers as you help shape our strategic security roadmap.

- Infrastructure and industrial security — Infrastructure as Code (Terraform), Kubernetes security, and — uniquely for this role — securing the lab environment itself: instrumentation, control systems, embedded/firmware security, and OT/ICS hardening across our quantum R&D equipment.
- Leadership — mentoring engineers, driving continuous improvement, and partnering closely with engineering, IT, hardware, and physics teams to embed security by design without slowing down research.
Requirements
- 5+ years of experience in cybersecurity or a closely related engineering role
- Proven hands-on experience with Infrastructure as Code (Terraform)
- Solid experience securing containers and Kubernetes environments

- Strong hands-on experience with identity technologies (SSO/SAML/OIDC, SCIM)
- Proficiency with security monitoring tooling (EDR/XDR, SIEM, audit logging)
- Solid scripting and automation skills (Python, Bash, or similar)
- Practical experience with application security tooling (SAST/DAST, SCA) and CI/CD security integration
- Degree in Computer Science, Cybersecurity, or a related field (Bac+3 to Bac+5), or an equivalent self-taught/bootcamp background with a proven track record
- Strong ownership and autonomy, clear communication with technical and non-technical stakeholders, and a genuine mentoring mindset
Nice to have
- Experience with cloud platforms (GCP, AWS, or Azure)
- Familiarity with security frameworks (ISO 27001, SOC 2, NIST)
- Exposure to embedded, firmware, or operational technology (OT/ICS) security — ideally in a lab or industrial setting
- Experience defining or maturing a DevSecOps program

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
The expansion of hardware development in universal quantum computing introduces complex operational security vectors that span software supply chains, enterprise access controls, and physical laboratory instrumentation. As deep-tech ventures scale toward fault-tolerant systems, protecting proprietary hardware architectures, intellectual property, and research data against sophisticated cyber threats becomes a foundational governance requirement. Specialized cybersecurity expertise is structurally necessary to secure the bridge between classical cloud interfaces and experimental physics environments. This engineering function ensures that research velocity remains uncompromised while enforcing strict integrity across distributed build pipelines and specialized control systems. Market signals indicate that securing early-stage quantum infrastructure is critical to maintaining partner trust and securing compliance alignment across international supply chains. Ultimately, robust security engineering serves as a key operational risk mitigation mechanism during the transition from laboratory-scale experiments to commercial computing deployments.
The quantum hardware ecosystem occupies a unique position in the global deep-tech value chain, operating at the intersection of high-performance computing, advanced material physics, and cloud-hosted API access layers. As quantum platforms advance along Technology Readiness Levels (TRLs), infrastructure vulnerability profiles shift dramatically from isolated academic configurations to interconnected enterprise networks. Organizations scaling superconducting architectures, such as those pioneered by Alice & Bob, must safeguard complex experimental control loops, embedded firmware, and proprietary hardware layouts against potential industrial espionage or system disruption.
Security within this sector is heavily influenced by macro constraints, including strict regulatory scrutiny, cross-border intellectual property protections, and high vendor fragmentation across specialized control electronics. The integration of Infrastructure as Code (IaC) and automated continuous deployment models must accommodate non-standard lab hardware alongside traditional cloud services. Consequently, building defense-in-depth frameworks across both corporate IT systems and operational technology (OT) laboratory assets represents a primary bottleneck for scaling fault-tolerant technologies safely.
Furthermore, national quantum initiatives and venture investment frameworks increasingly treat systemic resilience as a prerequisite for commercial partnerships. The security maturity of a quantum computing enterprise directly impacts its capacity to integrate with public research networks, defense initiatives, and enterprise early-adopters. Ongoing ecosystem initiatives aim to accelerate readiness for practical quantum applications by establishing secure baseline environments that support rapid, iterative physics research without exposing critical underlying IP.
The capability architecture for security engineering in quantum environments requires unifying corporate identity infrastructure with specialized lab control protections. Expertise spans automated infrastructure provisioning, container security, access management, and vulnerability detection integrated directly into software deployment cycles. Crucially, this technical layer must bridge cloud-native DevSecOps patterns with operational technology, securing low-level instrumentation, embedded controllers, and custom physics hardware networks.
These capabilities directly influence research throughput and enterprise readiness by establishing deterministic safety protocols across computing environments. Securing software pipelines ensures that firmware, calibration logic, and system algorithms remain unaltered throughout testing cycles. Simultaneously, robust identity frameworks prevent unauthorized lateral movement between corporate communication channels and sensitive R&D assets, protecting core IP while maintaining seamless internal access. - Hardens physical and digital research infrastructure against external threats and industrial espionage
