About Marcurius Multi-Mission Solutions

Marcurius Multi-Mission Solutions is a fast-growing defense technology company headquartered in the Tampa Bay area, Florida. Founded by U.S. and U.K. veterans, Marcurius brings decades of frontline experience across Special Operations and Intelligence missions, with deep expertise in asymmetric warfare and the real-world employment of unmanned systems.

Marcurius is building a new kind of unmanned systems company- multi-domain, multi-platform, and mission-driven. We integrate battle-proven platforms, resilient command-and-control architectures, and operator-led doctrine to deliver capabilities that work in contested environments. Our initial focus is the rapid fielding of advanced Unmanned Surface Vessels (USVs) for modern maritime operations.

Role Overview

The Communications Engineer supports the Lead Communications Engineer in the hands-on integration, testing, troubleshooting, and improvement of resilient communications systems across Marcurius platforms. The role covers line-of-sight (LOS) and beyond-line-of-sight (BLOS) links, tactical radios, secure networking, SATCOM, cellular connectivity, and autonomous command-and-control systems, ensuring reliable platform connectivity and mission effectiveness in demanding environments.

Key Responsibilities

• Support the integration of communications architectures across Marcurius platforms, including LOS/BLOS links, tactical radios, mesh networks, SATCOM, LTE/5G, and commercial technologies.
• Install, configure, test, and troubleshoot radios, routers, satellite terminals, secure network devices, and associated platform infrastructure.
• Implement approved resilience measures, including redundancy, failover, frequency management, interference mitigation, and alternative communications pathways.
• Support integration with autonomy, mission systems, and command-and-control applications to maintain reliable vehicle connectivity and operational control.
• Conduct RF performance testing and operational validation during development, harbour trials, sea trials, demonstrations, and end-user evaluations.
• Evaluate third-party equipment and vendor recommendations, identify technical or integration risks, and provide clear findings to the Lead Communications Engineer.
• Maintain system diagrams, interface records, equipment configurations, installation procedures, test evidence, and troubleshooting documentation.

Required Qualifications

• Degree in Communications, RF, Electrical, Computer Engineering, or a related discipline.
• 5-7 years of experience in communications systems engineering, RF engineering, network integration, or a closely related field.
• Demonstrated experience integrating communications systems across complex platforms or distributed operational environments.
• Strong knowledge of LOS/BLOS architectures, tactical datalinks, IP networking, resilience principles, and secure networking or encryption technologies.
• Strong analytical and troubleshooting skills, with the ability to assess third-party solutions and maintain clear technical documentation.
• Must possess, or be eligible to obtain and maintain, a U.S. Government Secret Security Clearance.

Preferred Experience

• Experience with Department of Defense, tactical communications, SATCOM, software-defined radio, or military network architectures.
• Experience supporting unmanned, autonomous, maritime, or command-and-control systems.
• Experience operating or testing communications in contested or electronically degraded environments.
• Experience working directly with military users, defense customers, or operational end users.
• Relevant certifications such as CompTIA Network+, Security+, Cisco CCNA, military communications qualifications, or vendor-specific training.

Why This Role Matters

Reliable communications are fundamental to every autonomous platform and mission system delivered by Marcurius. This role turns communications architectures into working, tested, and supportable platform capability, helping ensure that radios, networks, datalinks, satellite systems, and command-and-control interfaces operate together reliably in real-world conditions.

Physical Requirements

• Ability to work onsite in engineering, integration, and testing environments, including aboard vessels and in confined technical spaces.
• Ability to stand, walk, bend, kneel, climb ladders, and lift up to 50 lbs.
• Ability to work outdoors in varying weather conditions during testing and sea trials.
• Willingness and ability to travel for supplier visits, testing, demonstrations, and operational support.
