In this role, you will perform as an Integrated Functional Capability (IFC) Lead for the NATO Business Area and will be responsible for leading a diverse engineering team to provide imaginative, technical solutions to a wide range of difficult problems. This role is responsible for defining, controlling, and certifying system interfaces; ensuring that interface baselines are technically sound, well documented, and fully integrated to drive IFC strategy supporting new capability insertion. The IFC Lead partners closely with Systems Engineering, Software, Hardware, Integration & Test, Safety, and Cyber to reduce integration risk and enable predictable, high-quality program execution. You will be working across the entire spectrum of the Systems Engineering V-Model, and will support SE disciplines including requirements development, use case development, capability (hardware and software) development, integration planning, lab integration, test planning, formal test, and verification.
Essential Functions
- Serve as the technical authority for IFC on the program, owning the interface baseline across allocated subsystems and external stakeholders.
- Define and execute the IFC certification process for software and hardware builds, including planning, verification, and formal approval.
- Lead and/or chair IFC-related meetings (e.g., IFC Daily Execution, IFC Certification Reviews)
- Evaluate Engineering Change Proposals (ECPs), change requests, and new capability insertions for IFC impacts; provide clear recommendations to program leadership and configuration control boards.
- Develop a strategic IFC roadmap for the program/mission area, aligning interface evolution with planned capability increments.
- Lead root-cause investigations for IFC-related anomalies in lab and field environments; drive corrective actions and verification of fixes.
- Prepare and deliver IFC certification packages, including technical rationale, test evidence, risks/limitations, and formal recommendations.
- Identify IFC-related technical risks and opportunities; maintain and communicate mitigation plans.
- Provide technical mentoring to junior and mid-level systems engineers in IFC Management, integration, and interface analysis.
- Influence program strategy and planning by providing IFC insights into staffing, schedule, and technical risk.
- Work closely with Program Management, Chief Engineers, SE IPT leads, Software, Hardware, and Operations to ensure IFC work is integrated with broader program objectives.
- Represent IFC topics in program reviews (SRR, PDR, CDR, TRR, demos) and customer meetings, providing clear, concise technical status and recommendations.
Basic Qualifications
- Bachelor’s of Science in a STEM discipline (e.g., Systems Engineering, Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering) with typically 9+ years of related experience; or a Master’s degree with 7+ years; or PhD with 4+ years.
- Demonstrated experience in Systems Engineering with a focus on interface control, integration
- Strong analytical and problem-solving skills; ability to quickly understand complex system interactions and define valid solution sets.
- Effective written and verbal communication skills, including the ability to create clear technical documentation and present to technical and program leadership.
- Must have an active U.S. Government Secret clearance (with a background investigation within the past 6 years or enrolled into Continuous Evaluation)
Preferred Qualifications
- Prior experience as an IFC Lead, Integration Lead, or senior SE on complex aerospace/defense systems.
- Experience with IFC certification processes, accelerated release paths (e.g., AIR), and configuration control boards.
- Demonstrated ability to mentor and develop engineers and influence cross-functional teams without direct authority.
- Experience working with international Customers
