Job description

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 the Director of Engineering for Infrastructure at Harmattan AI, you will act as a vital management layer between R&D modules and leadership, focusing on elevating our people and standardising our engineering excellence. This is a "hands-off" people management role designed to relieve pressure on senior leadership by building high-performing teams, improving internal tooling, and standardising work processes across the company without sacrificing execution speed. You will be a visionary partner to our leadership, contributing to organisational structure and the long-term technical vision. In this role, you will lead our Engineering Infrastructure team in Paris - the foundation that all of R&D runs on, covering CI/CD, test-bench systems, internal developer tools, and the engineering-facing tooling that keeps every other team productive. Every engineering team in the company is your customer.

Responsibilities

• People Management & Mentorship: Act as a dedicated people manager for engineers, overseeing performance reviews, career growth, and training initiatives.

• Recruitment: Own the recruitment process as the number one priority, building and maintaining an effective engineering team to meet our ambitious growth plans in a competitive platform-engineering and developer-experience talent market.

• Process Standardisation: Develop and implement standardised work processes across CI/CD, test-bench, and developer-tooling teams to ensure high-quality output and consistency.

• Engineering Infrastructure: Audit and improve internal tooling - deciding between off-the-shelf and custom solutions - to ensure engineers have the best resources to succeed.

• Organisational Strategy: Contribute to the organisational structure by reorganising modules and initiating changes to optimise cross-functional (XFN) delivery.

• Vision & Execution: Collaborate with leadership to build the company vision, bringing fresh ideas to the table rather than just executing existing plans.

Candidate Requirements

• Educational Background: A strong academic record in Computer Science, Engineering, or a related technical field.

• Proven Leadership: Previous experience as an Individual Contributor (IC) who has successfully transitioned into a management role, allowing you to deeply understand the technical challenges your team faces.

• Experience: Direct experience leading a platform-engineering or developer-experience team at a hardware-plus-software company, with proven ownership of CI/CD, build infrastructure, and hardware test infrastructure (hardware-in-the-loop and software-in-the-loop testing, lab automation). You have served at least 50 engineering customers in a previous role and know how to balance feature requests against platform health.

• Technical Engagement: While this is a management-focused role, you should still possess a desire to "keep your hands dirty" and remain engaged with the technical aspects of the work.

• Soft Skills & Communication: Exceptional soft skills and communication abilities, with a "high-bar" for excellence and a natural ability to elevate those around them.

• Commitment: 100% dedication to Harmattan AI's mission of building autonomous defence systems and a readiness to thrive in a fast-paced, high-pressure environment.

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