System Integration Engineering

Employment Type: Direct Hire, Full-Time

Job Title: Integration Engineer

At 9 Mothers, we aren’t just "innovating"—we are building the shield.

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.

C2 & Third-Party Platform Integration: Design, build, and maintain integrations between our counter-drone system and external platforms, including Command and Control (C2) systems, sensor networks, and other mission systems used by our customers and partners.

Develop and maintain APIs, data feeds, and messaging interfaces (REST, SOAP, pub/sub, and similar) that expose our system's detection, tracking, and status data to external platforms in a reliable, low-latency manner.

Protocol & Standards Work: Implement and troubleshoot military and industry-standard data formats and messaging protocols (e.g., Cursor-on-Target, Link 16, VMF, TAK/ATAK, or comparable interoperability standards) as required by customer and partner systems.

Requirements & Interface Definition: Work directly with customers, partners, and internal engineering teams to gather integration requirements, define interface control documents (ICDs), and translate operational needs into technical specifications.

Testing & Validation: Build and execute integration test plans, including simulation and hardware-in-the-loop testing, to verify correctness, timing, and reliability of data exchange between systems before and during field deployment.

Field & Customer Support: Support integration efforts during customer demonstrations, pilots, and field deployments, troubleshooting issues across the full stack—from our system, through the network, to the receiving platform.

Integration Experience: 5+ years of hands-on experience as an integration engineer, systems integration engineer, or similar role, integrating software products with external enterprise systems.

Strong working knowledge of APIs (REST/SOAP), messaging and pub/sub systems, data serialization formats (JSON, XML, Protobuf), and general middleware/integration patterns.

Programming & Tooling: Proficient in at least one modern programming language commonly used for integration work (e.g., Python, Kotlin, C++, or C#), with the ability to read and write production-quality integration code.

Systems Troubleshooting: Comfortable diagnosing issues across the network, application, and data layers when an integration isn’t behaving as expected—strong understanding of TCP/IP networking and system-level debugging.

Independence & Ownership: Resourceful self-starter comfortable working directly with customers and partners, owning ambiguous integration problems end-to-end, and navigating shifting priorities in a fast-moving startup environment.

Compliance: This position requires access to export-controlled information under ITAR. S. citizens are permitted. Military C2 Experience: Direct experience integrating with Command and Control (C2) systems or other military mission systems, including familiarity with formats/protocols such as Cursor-on-Target, Link 16, VMF, STANAG (4586, TDL, etc), or TAK/ATAK

Development Environment Experience: Familiarity with Android Studio (for ATAK development) and Visual Studio (for Windows-based C2 integration)

Experience working in a regulated, ITAR, CMMC, or compliance-bound defense environment, or prior experience at a defense contractor or with DoD customers

Experience working with radar, EO/IR, RF, or other sensor data, telemetry streams, or counter-UAS/counter-drone systems

Active security clearance or eligibility to obtain one

Meaningful Early Equity: You aren’t just an employee; We build systems the Department of War actively needs to counter immediate, real-world threats.

The Builder’s Playground: Work in a brand-new lab fully optimized for rapid prototyping, equipped with NVIDIA Jetsons, high-end scopes, and 3-D printers.

100% Employer-Paid Premiums: We cover 100% of your medical, dental, and vision insurance premiums and cover 50% of healthcare premiums for your dependents.

Join an onsite team in Austin, TX, where we prioritize high-bandwidth collaboration and rapid field-testing.

Relocation Assistance: We want the best talent in the room. If you aren’t in Austin yet, we'll help you get here, to make your transition to the Silicon Hills seamless.
