 Security Clearance Status: Not Required We are seeking an experienced Senior Principal Systems Engineer to lead the definition, design, and development of a next-generation architecture for the STARS (Standard Terminal Automation Replacement System) platform. The ideal candidate will bring deep systems engineering expertise, demonstrated leadership in large-scale system architecture modernization, and advanced proficiency with Cameo Systems Modeler and model-based systems engineering (MBSE) methodologies. This role will serve as the technical architect responsible for shaping the system’s long-term architectural vision, ensuring alignment with program goals, safety requirements, and future scalability needs. The candidate will collaborate closely with cross-functional engineering teams, program leadership, and external stakeholders to drive a cohesive, sustainable architectural baseline.

Lead the architecture development effort for the next-generation STARS system, including conceptual architecture, logical and physical architectures, and interface definitions. Develop and maintain high-quality MBSE models using Cameo to represent system behavior, structure, interfaces, constraints, and verification pathways. Perform architecture trade studies and define technical roadmaps to guide modernization efforts. Collaborate with systems engineering, software engineering, hardware engineering, integration/test, and program management to ensure architectural alignment and feasibility. Establish and enforce architectural and modeling standards, patterns, and best practices. Support requirements decomposition and allocation using MBSE techniques to ensure traceability and consistency across system artifacts. Present architectural concepts, analyses, and decision rationales to internal and external stakeholders, including leadership and customers. Mentor junior engineers in MBSE methodologies, Cameo usage, and system architecture principles. Ensure all architectural work complies with safety, regulatory, and certification requirements relevant to NAS systems.

You Must Have: Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 10 years prior relevant experience or an Advanced Degree in a related field and minimum 7 years of experience 10+ years of experience in complex system architecture, systems engineering, or equivalent roles. Proven experience developing architectures for safety-critical, mission-critical, or large-scale distributed systems. Expert-level proficiency with Cameo Systems Modeler, SysML, and MBSE processes. Strong knowledge of system requirements, interface design, integration, and verification strategies. Demonstrated ability to lead architectural efforts from concept through implementation. Excellent communication, presentation, and technical leadership skills.

We Prefer: Experience with FAA systems, ATC/ATM domain, or other highly regulated environments. Familiarity with STARS or related NAS infrastructure. Experience with digital engineering pipelines, model governance, or toolchain integration. Knowledge of enterprise architecture frameworks (DoDAF, UAF). What We Offer : Some of our competitive benefits package includes:    Medical, dental, and vision insurance   Three weeks of vacation for newly hired employees   Generous 401(k) plan that includes employer matching funds and separate employer retirement contribution, including a Lifetime Income Strategy option   Tuition reimbursement
