Are you obsessed with building cloud-native platforms that enable engineers to operate at internet scale?

Then join us as our new Senior Infrastructure Engineer and be part of defining the next generation of the Infrastructure platform at Hadrian!

Who are we?

What if cybersecurity could think like a hacker?

At Hadrian, that's exactly what we're building: the future of offensive cybersecurity, powered by autonomous AI agents that think like hackers. Founded in Amsterdam in 2021, we're on a mission to change the way organisations defend themselves by helping them find and fix security weaknesses before attackers can exploit them.

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.

Our Stack:

• GoLang / Python

• KNative Serving & Eventing / Kafka / Redis

• Docker / Kubernetes / Helm Charts

• Terraform / OpenTofu

• PostgreSQL / BigQuery

• AWS / GCP / SCW (plus)
