Job Description:

L3Harris Agile Development Group (ADG) is seeking a Lead Field Engineer to join our Flight Test and Evaluation (T&E) team supporting our family of Unmanned Aircraft Systems (UAS) and Launched Effects (LE) capabilities. The portfolio includes deployable mission effects that can support precision kinetic strike and electronic warfare. The Lead UAS Field Engineer is the senior technical field representative for developmental flight testing, end-user integration, and training. Operating across lab and field environments, this role leads the technical execution of complex test and fielding activities and serves as a primary interface among engineering teams, customers, end-users, and test-range personnel to ensure mission success.

This is a mission-focused, highly technical position requiring comprehensive UAS systems knowledge, sound engineering judgment, and strong organizational, communication, and problem-solving skills. The role provides technical leadership for event planning, system integration and readiness, complex troubleshooting, maintenance strategy, training, and customer support. The Lead UAS Field Engineer works with minimal oversight against established objectives; resolves ambiguous system-level issues; leads cross-functional initiatives of substantial importance; and drives improvements to field-engineering practices, systems, and processes.

Essential Functions:

  • Lead the technical planning, integration, execution, and post-event assessment of developmental UAS flight test, launched-effects integration, and field deployment activities.
  • Serve as the primary technical field liaison among engineering teams, customers, end-users, test-range personnel, and other external stakeholders; communicate system status, risks, technical decisions, and recommended courses of action.
  • Lead cross-functional resolution of complex UAS and launched-effects system, subsystem, software, firmware, ground-control, communications, and test-support issues; conduct root-cause investigations and drive corrective actions with engineering teams.
  • Define and manage field-engineering readiness plans, technical objectives, acceptance criteria, configuration baselines, and deployment risks for assigned programs and test events.
  • Oversee system assembly, inspection, setup, configuration, preflight checkout, maintenance, and readiness activities; provide hands-on technical support as required for safe and successful operations.
  • Lead the setup, integration, operation, and troubleshooting of ground control stations, antenna systems, telemetry links, and test-support equipment, including software and firmware updates and configuration management.
  • Evaluate operational and test data, identify system performance trends, and provide technically sound recommendations that influence product design, test strategy, field procedures, and customer support approaches.
  • Establish, improve, and implement field-engineering processes, technical standards, work instructions, and readiness practices that improve mission performance and reduce operational risk.
  • Lead technical briefings and debriefings for program leadership, engineering teams, customers, and operational stakeholders; clearly communicate complex technical information, findings, and recommendations.
  • Provide senior-level customer support through remote and on-site methods, including issue resolution, technical escalation, corrective-action follow-through, and post-event engagement.
  • Train end-users and customer support personnel in the maintenance, operation, troubleshooting, and safe use of UAS, launched-effects capabilities, associated user interfaces, and proprietary software; assess proficiency and address technical knowledge gaps.
  • Mentor and provide technical guidance to field technicians, field engineers, and other team members, review work products, and support development of technical capability across the team.
  • Coordinate technical aspects of field logistics, equipment preparation, shipping, and deployment readiness across multiple programs; ensure required equipment, documentation, and personnel are prepared for scheduled events.
  • Represent L3Harris professionally in customer, end-user, and test-range interactions; build effective working relationships and influence adoption of sound technical practices and solutions.
  • Occasionally work 12+ hour shifts, including nights, weekends, holidays, and on short notice as operational demands require.
  • Ability to move 51 lbs. unassisted or 100 lbs. as part of a two-person team.
  • Ability to travel CONUS and OCONUS up to 50% of the time.

Qualifications:

  • Bachelor’s Degree in Engineering or another relevant technical discipline and a minimum of 9 years of prior relevant experience. Graduate Degree and a minimum of 7 years of prior relevant experience. In lieu of a degree, minimum of 13 years of prior relevant experience.
  • Active U.S. TS/SCI security clearance.

Preferred Additional Skills:

  • Military experience or experience supporting military customers.
  • Demonstrated expertise with UAS and launched-effects operations, aviation fundamentals, mission planning, systems integration, and test-range operations.
  • Experience leading developmental or operational test activities in a high-tempo, high-consequence environment.
  • Experience with systems engineering, complex equipment integration, configuration management, and technical risk management.
  • Experience conducting root-cause analysis and developing corrective actions for complex hardware, software, communications, or system-integration issues.
  • Experience generating technical work summaries, discrepancy reports, test reports, readiness assessments, and customer-facing technical briefings.
  • Experience monitoring and analyzing telemetry data; developing test approaches; and leading technical test briefings and debriefings.
  • Experience serving as a technical liaison to customers, end-users, engineering teams, and external operational stakeholders.
  • Experience developing, improving, and implementing field procedures, maintenance strategies, training materials, or technical standards.
  • Knowledgeable of basic explosive hazard controls and system safety
  • OSHA requirements and ESD best-practices familiarity.
  • Strong hands-on mechanical, electrical, and troubleshooting skills, including computer networking and the ability to interpret schematic diagrams and technical documentation.
