Senior Infrastructure Engineer

_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.

• 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.
