- Minimum 4 years of experience shipping highly performant, data-intensive front end software applications.
- Expertise with React, JavaScript/TypeScript and CSS, Vite, Jest/Vitest and Playwright.
- Demonstrated ability to build products from the ground up, translate customer problems to well-scoped engineering tasks, determine task priority and sequencing, and operate under limited or ambiguous requirements.
- Strong fluency with state management, responsive design, and performance optimization.
- Proficiency maintaining design systems, and component libraries.
- Ability to work extended hours and/or weekends as needed for mission critical deadlines.
- ITAR Requirements: To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
- Empathetic User Experiences: Carefully curate intuitive interfaces and workflows that surface immediately actionable spectrum insights, compound the effectiveness of a single EW operator, and minimize cognitive load on users.
- Dynamic, Low Latency Applications: The electromagnetic battle space changes rapidly, our platforms should as well. You’ll prioritize both low latency and rich interactivity as you build, but you’ll also understand when and how to handle tradeoffs in imperfect conditions.
- Mobile and Web Functionality: Users will leverage CX2 from both touchscreen mobile devices and larger computers with various network and compute capacity. Optimizing performance and usability for a variety of form factors and hardware requires careful resource management, continuous evaluation of new tools and frameworks, and detailed software observability.
- Experience with APIs (REST, GraphQL, WebSocket).
- Familiarity with web security, authentication, and authorization.
- Experience developing applications that function offline or do not require constant internet access (PWAs).
- Proficiency with responsive web experiences.
- Bachelor's degree in Software Engineering or a related field strongly preferred.
CX2 develops AI-enabled hardware and software to manage the electromagnetic spectrum for military use. Its platform autonomously detects, classifies, and counters RF threats at the tactical edge, providing spectrum awareness and emitter tracking with GPS-denied capability and optional high-resolution imagery for threat confirmation. The system is modular and hardware-agnostic, designed to be deployed on drones or vehicles and updated quickly at lower cost compared with traditional EW systems. The goal is to enable rapid, targeted responses to RF threats to protect missions for the U.S. military and its allies, leveraging a leadership team with deep military, defense, and tech experience.

Defense tech startup CX2, co-founded by Nathan Mintz and Porter Smith, announced a $31M Series A funding round in May 2023. The round was led by Point72 Ventures, with participation from new investors like Upfront Ventures, Pax Ventures, and 201 Ventures, as well as existing investors Andreessen Horowitz and 8VC. CX2 focuses on electronic warfare systems, aligning with the evolving nature of warfare, as seen in the Ukraine conflict.
Electronic warfare startup CX2 has raised $31 million in a Series A round led by Point72 Ventures, with participation from Andreessen Horowitz, 8VC, and Pax Ventures. The funding will help CX2 hire more staff and accelerate the development of its electronic warfare tools. CEO Nathan Mintz highlighted the importance of mastering the electromagnetic spectrum, especially in light of the Ukraine conflict. CX2 works with the U.S. Army's 10th Mountain Division and builds software and hardware for electronic warfare.
CX2, which is still in stealth, is being led by serial entrepreneur Nathan Mintz, who co-founded the counter-drone unicorn Epirus.
