Lead Systems Engineer / Integration Lead

Marcurius Multi-Mission Solutions is a fast-growing Defense technology company headquartered in Clearwater, Florida. Founded by US and UK 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 fuse battle-proven technologies, 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.

We are looking for a Lead Systems Engineer / Integration Lead to own the technical architecture across multiple craft classes and ensure hull, electrical, autonomy, mission systems, and vendor-delivered subsystems come together as one coherent product family.

This is a high-impact, hands-on leadership role at the center of the program. You will define and enforce system architecture, control interface logic across all subsystems, manage requirements and verification, and drive technical integration across internal teams and external partners.

You are not coordinating the system — you are responsible for making it work.

This role is critical to early program success. Poor interface control and architectural drift create integration issues that are difficult to recover later in the program.

Experience with unmanned systems in maritime, air, or ground environments

Familiarity with MBSE / SysML tools

Maritime or naval systems exposure

Startup, prototype, or early-phase product development experience

Active security clearance or ability to obtain one

This role is the integration nerve center of the program. The right person will prevent interface debt, enforce architectural discipline, align vendors and internal engineering, and ensure the system develops as a coherent, testable, and deliverable product family.

Onsite engineering and build environment

Direct involvement in prototyping and sea trials

Fast-paced development cycles with aggressive timelines

Customer, end-user and internal team facing

Marcurius is a people-first, execution-focused organization assembling a high-impact team of Engineers and Operators. This role offers the opportunity to directly shape real-world systems, support strategic national security priorities, and be part of an incredibly exciting journey - building the foundations of a next-generation Defense technology company.
