About 9 Mothers
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.
Why 9 Mothers?
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.
Position Summary
9 Mothers is seeking a Perception Engineer to own the computer vision and machine learning stack that powers target detection, classification, and tracking in our counter-sUAS systems. The Perception Lead is responsible for the research, development, and deployment of the perception pipeline that enables EDDA to engage aerial threats in real time. This is a senior individual contributor position.

9 Mothers Policy on the Use of Artificial Intelligence (AI) During the Interview Process
The interviewing process is a mutual opportunity for us to get to know each other better. Our goal is to understand your unique background, evaluate your problem-solving abilities, and ensure a strong mutual fit.
AI is a core part of how we work at 9 Mothers—we actively encourage and frequently leverage AI tools in our day-to-day operations. However, during the hiring process, we need to evaluate your fundamental skills and expertise, not the outputs of an AI model.
To ensure a fair and transparent process, we ask that you adhere to the following interview guidelines:
- 1st-Round Interviews (No AI Allowed): The use of AI tools, assistants, code generation tools, or real-time copilots is strictly prohibited during all first-round interviews and assessments. The use of AI during this stage will result in immediate disqualification from the hiring process.
- 2nd-Round Interviews (Guided AI Usage): The second-round process includes opportunities to utilize AI. Your interview team will provide explicit guidance on how, when, and which AI tools to leverage during this stage.
We appreciate your cooperation in helping us maintain an authentic and fair interview experience for everyone.
