Senior Infrastructure Engineer

Our platform brings together two products: Atlas, which continuously maps an organisation's external attack surface and validates which exposures are genuinely exploitable, and Nova, which uses AI agents to perform in-depth penetration testing on demand. Together, they give security teams the visibility and proof they need to focus on what really matters and stay ahead of emerging threats.

Backed by $65M in total funding, including our recent $40M Series B led by Forgepoint Capital International and SmartFin, we're investing in the next generation of autonomous offensive security and expanding our impact across global markets. With a team spanning 25+ countries and offices in Amsterdam, London, and New York, we're helping organisations rethink what's possible in cybersecurity.

Join us and help shape the future of offensive security.

Your role:

As a Senior Infrastructure Engineer at Hadrian, you will design, build, and evolve the cloud-native platform that powers our offensive security operations. You will enable engineering teams to move faster, deploy safely, and operate reliably by creating scalable self-service infrastructure and resilient platform capabilities.

This role is ideal for engineers who enjoy combining deep infrastructure expertise with a strong software engineering mindset. We're looking for someone who thrives on automation, reliability, and platform design, and who sees infrastructure as a product that empowers others to do their best work.

If you enjoy solving complex distributed systems challenges, building developer-friendly platforms, and creating the foundations that allow autonomous security systems to operate at scale, we would love to hear from you

What you will do as a Senior Infrastructure Engineer at Hadrian:

* Help build and maintain the cloud-native platform that powers Hadrian's offensive security systems.

* Design and automate infrastructure delivery using Infrastructure-as-Code, enabling scalable and self-service platform capabilities.

* Manage and improve our Kubernetes environment, ensuring reliability, performance, and security.

* Collaborate closely with software engineers to improve deployment workflows, developer experience, and platform adoption.

* Operate and optimize our core cloud infrastructure on AWS, while supporting our distributed scanning environments.

* Improve observability, monitoring, incident response, and platform reliability across critical systems.

* Help implement platform standards, security controls, and engineering best practices that enable teams to move quickly and safely.

* Take on a unique challenge. We’re building autonomous security systems that continuously analyze internet-scale attack surfaces. You'll help create the platform that makes this possible.

You are fit for this job because you:

* Have 4+ years of experience as an Infrastructure Engineer, Platform Engineer, DevOps Engineer, SRE, or similar role.

* Have hands-on experience with Kubernetes, AWS, and Terraform (/OpenTofu), and are comfortable operating cloud-native infrastructure in production environments.

* Are comfortable managing core environments on AWS while extending workloads into secondary cloud environments used for scanning.

* Have a solid foundation in systems engineering, containerization (Docker), and distributed systems.

* Are experienced with automation and CI/CD tooling, such as Terraform, Ansible, Jenkins, or GitLab CI.

* Enjoy building platforms, tooling, and automation that help engineering teams move faster and more safely.

* Possess strong troubleshooting and problem-solving skills, and enjoy solving reliability, scalability, and operational challenges.

* Use AI pragmatically to accelerate workflows while maintaining high standards of reliability and security.

* Communicate clearly and collaborate effectively across technical teams.

Bonus points if you have:

* Experience with KNative, event-driven architectures, or service mesh technologies.

* Experience with Kafka or other distributed messaging systems.

* Hands-on experience with observability and monitoring tooling.

* Familiarity with Site Reliability Engineering (SRE) practices.

* Certifications related to Kubernetes such as CKA, CKAD, or AWS certifications.

* Contributions to open-source infrastructure or cloud-native projects.
