@Orchard LLC is supporting a leader in secure communications systems for the most challenging environments. Our client (SEMPRE) believes that life depends on communication. They are a team of engineers and entrepreneurs dedicated to one mission: protecting, connecting, and securing communication so life runs uninterrupted—even on our nation's "worst day." SEMPRE provides the world’s first EMP-hardened, 5G-enabled, edge micro-data centers. Our technology bridges the gap between commercial innovation and military-grade survivability, ensuring that military units, first responders, and critical infrastructure operators have access to secure, resilient, and autonomous digital infrastructure. When traditional networks fail due to kinetic attack, cyber warfare, or natural disaster, SEMPRE stands.

As a Senior Field Service Engineer (FSE), you are the technical vanguard of SEMPRE’s mission. You won’t just be maintaining equipment; you will be ensuring tactical superiority and operational readiness in high-stakes environments. You will provide on-site technical support, system integration, and operational assistance for a sophisticated ecosystem of Counter-Unmanned Aircraft Systems (C-UAS) sensors and communications platforms. This role requires someone comfortable navigating RF spectrums, EO/IR imaging systems, and complex IP networking, all while serving as the primary bridge between SEMPRE’s engineering teams and the warfighters on the ground.

Your responsibilities will include:

• Operational Readiness: Provide expert field-level installation, configuration, and maintenance for C-UAS communications and sensor systems.
• Multi-Vendor Integration: Support the seamless integration of high-tier platforms, including Dedrone detection systems, Teledyne & FLIR EO/IR imaging, and the AeroVironment Titan C-UAS System.
• Technical Troubleshooting: Diagnose and resolve hardware, software, and RF communication issues. You will manage the intersection of Linux/Windows environments, IP networking, and hardened field hardware.
• Sustainment: Conduct preventive maintenance, system health checks, and critical firmware/software updates to ensure 100% mission uptime.
• Strategic Deployment: Assist with site surveys and communications architecture to optimize sensor coverage and minimize "digital exhaust" in contested environments.
• Training & Mentorship: Act as a subject matter expert, training operators and customer personnel on system safety, operation, and field-level troubleshooting.
• Liaison: Coordinate directly with SEMPRE engineering and OEM vendors to escalate complex issues and influence future product hardening.

Your background will include.

• Citizenship: U.S. Citizenship and the ability to obtain/maintain a Secret Security Clearance.
• Domain Knowledge: Must have prior active-duty experience supporting Global Strike Command (AFGSC), including experience supporting nuclear capabilities.
• Technical Experience: 3+ years supporting C-UAS, ISR (Intelligence, Surveillance, and Reconnaissance), RF, or defense communications systems.
• Field Expertise: Proven ability to troubleshoot IP networking, RF spectrum monitoring, and sensor fusion architectures in austere or military environments.
• Systems Knowledge: Familiarity with EO/IR imaging, radar systems, and Command-and-Control (C2) software.
• Adaptability: Comfortable working in dynamic, field-deployed settings supporting government and military customers.
• Communication: Strong technical documentation skills and the ability to translate complex technical concepts for non-technical operators.

Additional Preferred Qualifications

• OEM Familiarity: Prior experience with systems from Dedrone, Teledyne Technologies, FLIR Systems, or AeroVironment.
• Military Background: Direct experience in Air Defense, Signals (25 series), ISR, or Electronic Warfare (17/29 series).
• Security Architecture: Understanding of Zero Trust principles and how they apply to tactical edge computing.
• Active Clearance: Currently holding an active U.S. Secret clearance.

• Mission-First Culture: Work for a company where "Integrity, Service, and Innovation" aren't just posters on a wall—they are our operating model.

• Impact: Your work directly protects American lives and ensures our nation's critical infrastructure remains resilient against any threat.
