In this senior technical role, you will define the architectural vision, establish engineering best practices across multiple programs, guide cross-functional technical teams, and directly influence future product roadmaps and customer technology strategies. You will act as the primary technical interface between software engineering, program leadership, chief engineers, and defense stakeholders., Has served as the designated software technical authority across major programs, establishing architectural frameworks, interface standards, and open architecture strategies (e.g., SOSA, FACE, OMS) that scale across product lines. Has supported design and code review, as appropriate. Has provided strategic technical direction to lead engineers and multi-disciplinary software teams across the entire lifecycle -from concept formulation through deployment and sustainment. Has led software teams to ensure consistency and maximize commonality of software across programs. Has partnered with Program Managers and Chief Engineers to establish software development plans (SDPs), drive technical, cost, and schedule accountability, and govern earned value execution (EVMS/BOEs) across major development contracts. Has coordinated with the leads for the program subsystems to ensure software elements meet subsystem requirements and to ensure common software elements are developed in a flexible and adaptable manner. Has championed and upheld the highest standards for safety-critical and high-reliability systems (e.g., DO-178C DAL A/B, MIL-STD-882), chairing architecture boards, review gates (SRR, PDR, CDR), and software qualification efforts. Has served as the escalation lead for systemic, high-consequence technical issues spanning software, real-time operating systems, firmware, custom silicon, and complex hardware interfaces. Has reviewed component design information and resolved design conflicts. Has identified software risk areas and provided plans to mitigate those risks. Has mentored and cultivated the next generation of software leads and architects; spearheading modern software engineering practices, toolchains, automated verification paradigms, and digital engineering transformations across the organization. Has experience providing direction and assistance to software engineers making complex design decisions. Why Join Us At Lockheed Martin, you'll work on meaningful programs that make a real-world impact while building a career with long-term growth and stability. We offer challenging work, supportive leadership, opportunities to learn and advance, and the chance to contribute to missions that matter.
