Only U.S. citizens are permitted. Must be willing to submit a background check. Nice-to-Have * 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) * Defense Industry Background: Experience working in a regulated, ITAR, CMMC, or compliance-bound defense environment, or prior experience at a defense contractor or with DoD customers * Sensor & C-UAS Familiarity: Experience working with radar, EO/IR, RF, or other sensor data, telemetry streams, or counter-UAS/counter-drone systems * Clearance: Active security clearance or eligibility to obtain one, * Part 1 (1 hour) - An evaluation of your core technical skills to confirm alignment with the required technical knowledge for this role. * Interview Break (15 min) - A quick pause to step away and grab a glass of water. * Part 2 (1 hour) - A deep dive into your hands-on experience with relevant technologies to explore your specific domain expertise. 3. 2nd/Final Round Interview (6 hours) onsite in Austin, TX * Hands-on Working Session (3 hours) - You'll work through a small project alongside our team. We'll look at how you approach problem-solving, leverage resources, and collaborate with team members to reach a solution. * Architecture Discussion (1-2 hours) - A discussion focused on big-picture thinking-evaluating how components interact, system design considerations, and architectural recommendations. * Wrap-up Conversations (30 min-1 hr) - Two 1:1 individual conversations to discuss team fit and address any questions you have for us. ## Description 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. * API & Interface Development: 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)[DC1] [EL2] 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. * Documentation: Produce and maintain clear integration documentation, interface specifications, and runbooks for internal teams and external partners. ## Related Videos - [Wolfenstein 3D Postmortem](https://www.wearedevelopers.com/videos/525-wolfenstein-3d-postmortem) - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [Tips and Tricks for Working with JSON](https://www.wearedevelopers.com/videos/1229-tips-and-tricks-for-working-with-json) - [Developers don't need onboarding, do they?
