About the role

Original posting from CHAOS Industries via Greenhouse

CHAOS Industries is redefining modern defense with a multi-product portfolio that gives the ultimate advantage—domain dominance. The company's products are powered by Coherent Distributed Networks (CDN™), empowering warfighters, commercial air operators, and border protection teams to act faster, adapt rapidly, and stay ahead of evolving threats. 

CHAOS Industries was founded in 2022 and has raised a total of $1 billion in funding from leading investors, including 8VC, Accel, and Valor Equity Partners. The company is headquartered in Los Angeles, with offices in Washington, D.C., San Francisco, San Diego, Seattle, and London. For more information, please visit www.chaosinc.com.

Role Overview 

As a Communications Systems Engineer, you will own the connectivity backbone of CHAOS's fielded systems — 5G/cellular, SATCOM (e.g. Starlink), point-to-point wireless, and tactical mesh radios. You will bring rigorous systems engineering practice to the comms domain: verifiable requirements with traceability, defined architectures and interfaces, disciplined trade studies, and verification from factory test through field deployment. Your mission is to ensure every communications solution is selected, qualified, validated, and ready for field deployment.   

You will also keep CHAOS ahead of the pace of commercial and tactical comms innovation, continuously scanning the landscape for emerging technologies — new radios, waveforms, multi-orbit SATCOM constellations, and software-defined networking approaches — and driving the most promising into the product baseline. This role is full-time onsite at our office in El Segundo, CA. 

Responsibilities 

Systems Engineering 

Translate mission, customer, and business needs into verifiable, traceable system and subsystem requirements for connectivity 

Develop and maintain connectivity architectures, interfaces, design descriptions, and ICDs across cellular/5G, SATCOM (LEO/MEO/GEO), point-to-point wireless, and tactical mesh networks 

Perform design analysis and verification — RF link budgets, key performance parameters (EIRP, G/T, C/N₀, Eb/N₀, throughput), antenna placement and pointing, handover behavior, and regulatory compliance 

Lead trade studies weighing performance, size/weight/power, cost, availability, and compliance — including forward-looking needs such as non-line-of-sight links, elevated relays, and GPS-denied synchronization 

Hardware Selection & Qualification 

Evaluate, select, and qualify comms hardware (cell modems, SATCOM terminals, P2P dishes, mesh radios) for field robustness and regional compatibility — verifying RF bands, regulatory suitability, and export/AT compliance before purchase or baseline, and managing regional variants in the product BOM 

Collaborate with suppliers, satellite operators, and service providers to develop and integrate connectivity solutions 

Integration & Test 

Integrate comms equipment into factory test plans with clear pass/fail criteria, and establish pre-ship verification on representative system hardware with in-country SIMs and bands 

Support system integration, troubleshooting, and root-cause analysis from lab through field deployment — driving corrective actions into the baseline; participate in technical reviews and embed with product scrums to verify baseline compatibility 

Deployment & Field Support 

Own the tested connectivity matrix across deployment countries (cellular bands, SATCOM legality and plans, spectrum constraints, validated fallbacks) along with configuration baselines and runbooks for all comms peripherals, in partnership with FDE, Mission, and IT 

Provide reach-back support to deployed teams during international demos and operations, with occasional travel to deployment sites 

Minimum Requirements 

Bachelor's degree in Electrical Engineering, Aerospace Engineering, Systems Engineering, Computer Engineering, or related technical discipline 

7+ years of experience in systems engineering supporting SATCOM, wireless communications, tactical networking, or connectivity products 

Experience developing, managing, and verifying system, subsystem, and interface requirements throughout the product lifecycle 

Working knowledge of SATCOM and RF communications systems, including satellite link analysis, antenna systems, and modem/RF chain fundamentals 

Working knowledge of cellular technologies and international band plans (LTE/5G NR), and practical experience with satellite internet terminals (e.g., Starlink) 

Strong understanding of IP networking concepts, including routing, switching, network protocols, VPNs, failover, and connectivity architectures 

Experience performing RF link budget analysis, antenna placement optimization, and line-of-sight/NLOS analysis in complex terrain 

Experience developing hardware test procedures and pass/fail criteria for production or integration environments 

Experience collaborating with customers, suppliers, and cross-functional engineering teams on complex technical programs 

Excellent problem-solving skills and a bias toward root cause over workaround 

Preferred Requirements 

Master’s degree in Electrical Engineering, Aerospace Engineering, Systems Engineering, Computer Engineering, or related technical discipline 

Experience with tactical mesh radios (e.g., MPU5/Wave Relay) and 60 GHz / 5 GHz P2P systems 

Familiarity with multi-orbit constellations (LEO/MEO/GEO), beam/satellite handover, and ground network integration 

Experience designing or integrating secure communications architectures, including authentication, encryption, VPNs, certificate management, and secure remote connectivity 

Experience analyzing communications performance in contested, degraded, or denied environments, including multi-path, interference, jamming, and dynamic network topology 

Experience with requirements management, Application Lifecycle Management (ALM), and/or Model-Based Systems Engineering (MBSE) tools such as Cameo, including multi-level requirements sets and traceability 

Familiarity with export control and supply-chain compliance considerations for communications hardware (e.g., country-of-origin restrictions) 

Scripting for test automation and network validation (Python, Bash) 

INCOSE certification or demonstrated application of systems engineering best practices 

Experience in a rapid-iteration hardware production environment 

Experience supporting international deployments of communications equipment, including regional regulatory and spectrum considerations 

Active or eligible U.S. security clearance
