About The Position

The Advanced Concept Engineer (ACE) serves as the technical liaison between L3Harris and its customers' engineering teams, supporting Business Development in generating new business opportunities. The ACE will engage with customer, engineering, operations, and management personnel to define and document customer CONOPS and requirements. This role involves performing trade studies, collaborating with L3Harris Subject Matter Experts (SMEs) to architect affordable solutions with acceptable risk, and leading resulting proposal efforts. The ACE must consider all customer needs, resources, and constraints, including mission objectives, budget limitations, technical preferences, physics boundaries, and the political climate, to build trust in both the ACE and L3Harris. During program execution, the ACE acts as the technical advocate and customer representative in program reviews. This position requires experience in systems engineering, system architecture development, competitive assessment, project engineering management, and development program execution. The Advanced Concept Engineer should possess expertise in multiple technical domains and an entrepreneurial background. This individual will collaborate closely with business development and senior management to address customer needs through technical presentations, white papers, and proposals; respond to RFPs, RFIs, and broad agency announcements; and provide market and SME guidance for business strategy and ongoing development efforts. Demonstrated communication and interpersonal skills, along with the ability to work cross-functionally between a large engineering enterprise and external partners, are essential.
