About Us

Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.

Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.

About the Role

As an Infrastructure Engineer based in Austin, TX, you will help build and run Harmattan AI’s U.S. infrastructure from the ground up, across networking, cloud, identity, endpoints, and user support. Working side by side with the U.S. Director of IT, you will share projects, support, and onboarding, and take on new responsibilities as the role evolves over the next 6–12 months from building infrastructure to running it.

Help design, deploy, and maintain infrastructure spanning networking, cloud, identity, and endpoints

Help implement and document security and compliance requirements across the environment

Review and test work delivered by vendors and integrators against technical requirements before go-live

Set up and manage Windows, Mac, and Linux devices, ensuring they are secure and meet company policies

Support cloud environments and virtual desktop infrastructure, and automate repetitive work through scripting and infrastructure as code

Share support tickets, device setup, and technical onboarding for new U.S. hires

Work closely with IT counterparts overseas, aligning with shared standards wherever possible

Requirements

Education: A specific degree is not required; hands-on experience matters more than field of study

7+ years of experience in infrastructure or systems engineering across a broad environment rather than a single specialty, including work with vendors or MSPs

Hands-on experience implementing defense-industry security and compliance frameworks, such as configuring controls, writing documentation, or supporting an assessment

Experience with major cloud platforms, virtual desktop infrastructure, enterprise productivity suites, and directory and identity services

Experience with enterprise networking, identity and access management, endpoint management, and endpoint security tooling

Proficient in scripting, automation, and infrastructure as code

Hands-on experience with Windows, Mac, and Linux endpoints, including managing Macs alongside Windows

Comfortable with ambiguity and shifting priorities, eager to take on work you haven’t done before, and able to work closely in a small team and across time zones

Commitment: 100% dedication to Harmattan AI’s mission, vision, and ambitious growth plans, ready to go the extra mile to ensure operational excellence.

Bonus: Defense industry experience, and certifications in cloud, networking, endpoint management, security, or compliance

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
