Integration Engineer

The modern battlefield has changed. Cheap, autonomous suicide drones have turned the tactical advantage upside down, and the world is looking for a solution. At 9 Mothers, we aren’t just "innovating"—we are building the shield.

Backed by top-tier investors, we develop AI powered machines designed to intercept and neutralize Group 1/sUAS threats in real-time. Our flagship product is a low-power, counter-drone system built for the edge—on vehicles, at bases, or in a soldier's pack.

While others build for "awareness" or "long-term research," we build for the immediate survival of those in harm’s way. We are a team of hackers, engineers, and mission-driven builders who value field-ready capability over polished slide decks. If you want to see your code or hardware in the field next month—not next year—this is your playground.

9 Mothers is hiring an Integration Engineer to connect our counter-drone platform with the broader ecosystem of systems our customers already run. In this role, you will design, build, and maintain integrations between our product and third-party enterprise and mission systems—most notably Command and Control (C2) platforms—so that our detection, tracking, and defeat capabilities plug cleanly into a customer's existing operational picture.

You will own the full integration lifecycle: understanding partner and customer system interfaces, defining data and messaging contracts, building and testing the integration, and supporting it through deployment in the field. This role sits at the intersection of software engineering, systems integration, and customer-facing technical work in a fast-moving defense startup environment.
