Design, analyze, and mature navigation algorithms, including inertial navigation, state estimation, sensor fusion, sensor calibration, alignment, integrity monitoring, and fault detection and isolation.
Develop robust estimation solutions that account for sensor noise, bias, drift, timing errors, misalignment, environmental disturbances, vehicle dynamics, computational constraints, and modeling uncertainty.
Establish rigorous methods for evaluating estimator observability, convergence, consistency, robustness, integrity, and degraded-mode behavior.
Lead technical discussions and design reviews, ensuring architecture and algorithm decisions are supported by appropriate analysis, test evidence, and system-level reasoning.
Identify technical deficiencies and risks, establish corrective-action and mitigation plans, and drive issues to resolution.
Serve as the technical authority for navigation architecture, algorithm design, sensor selection, and significant technical trade studies.
Performance Analysis, Implementation, and Flight Validation
Lead navigation performance analysis, uncertainty quantification, covariance analysis, Monte Carlo simulation, sensitivity studies, and error-budget development across nominal and off-nominal conditions.
Develop and maintain navigation simulation models, sensor error models, and software-in-the-loop and hardware-in-the-loop verification workflows.
Drive production implementation of navigation algorithms in embedded, real-time software, reviewing numerical stability, computational efficiency, coordinate conventions, timing, initialization, and fault-handling behavior.
Define specific ground and flight test objectives, instrumentation requirements, success criteria, and requirements-based verification plans.
Lead navigation data analysis, model correlation, performance assessment, anomaly investigation, and corrective-action validation.
Ensure navigation algorithms and hardware are appropriately characterized and validated against system-level requirements throughout development and flight testing.
Sensor Selection, Hardware Architecture, and Make-versus-Buy Decisions
Own the technical evaluation and selection of navigation sensors and related hardware, including IMUs, GNSS receivers, aiding sensors, and integrated navigation solutions.
Define sensor performance requirements based on mission needs, system-level error budgets, environmental constraints, interfaces, and navigation architecture.
Lead quantitative trade studies considering accuracy, noise, bias stability, bandwidth, latency, environmental robustness, size, weight, power, cost, availability, and integration complexity.
Evaluate make-versus-buy decisions for navigation hardware, algorithms, and integrated solutions, considering performance, development effort, lifecycle cost, schedule, maintainability, supplier support, and strategic value.
Assess supplier capabilities, component limitations, technology maturity, configuration control, and lifecycle risks to inform architecture and procurement decisions.
Define sensor characterization, calibration, qualification, and acceptance-test requirements to demonstrate that selected hardware meets system-level objectives.
Partner with Avionics, Electrical, Mechanical Engineering, Embedded Software, and Supply Chain teams to ensure successful hardware selection, integration, and lifecycle support.
Team Leadership and Development
Lead and develop a small team of navigation engineers, initially managing approximately three direct reports.
Establish clear responsibilities, priorities, individual objectives, deliverables, and performance expectations aligned with program milestones.
Delegate meaningful technical ownership while maintaining accountability for team outcomes and navigation deliverables.
Provide regular technical feedback, mentorship, coaching, and professional-development opportunities.
Identify individual strengths and development areas, assigning responsibilities that build increasing engineering independence and technical depth.
Proactively address performance issues, technical blockers, unclear ownership, and team inefficiencies.
Recognize when specialized expertise is required and engage the appropriate subject-matter experts.
Foster a culture of technical rigor, accountability, collaboration, constructive challenge, and continuous improvement.
Engineering Judgment and Program Execution
Independently identify and prioritize the highest-value engineering activities based on program objectives, technical risk, schedule, and available resources.
Develop clear technical recommendations for ambiguous problems, evaluating alternatives, trade-offs, consequences, and residual risks.
Make timely engineering and execution decisions within delegated authority without unnecessary reliance on GNC leadership.
Exercise sound judgment in determining when additional analysis, algorithm complexity, hardware capability, or engineering effort provides meaningful value.
Challenge assumptions, requirements, and proposed approaches when supported by sound engineering reasoning.
Balance technical performance, reliability, architectural complexity, development cost, schedule, and program risk.
Communicate significant decisions with a clear recommendation, supporting evidence, alternatives considered, and associated risks.
Take ownership of technical and team outcomes rather than only coordinating or executing direction established by others.
Cross-Functional Leadership and Team Effectiveness
Serve as the primary navigation partner to Guidance, Controls, Avionics, Embedded Software, Aerodynamics, Mechanical Engineering, Test, and program leadership.
Coordinate navigation requirements, interfaces, integration activities, dependencies, and cross-functional deliverables.
Contribute to system-level trade studies and concepts of operations, identifying navigation requirements, performance limitations, uncertainty impacts, and integration risks.
Build effective working relationships across disciplines and independently resolve organizational and technical coordination challenges.
Communicate team progress, technical risks, resource needs, schedule impacts, and mitigation plans clearly to engineering leadership and stakeholders.
Establish reusable estimation methods, analysis tools, engineering standards, and development processes that improve quality and execution speed.
Allocate engineering resources to work that materially improves system performance, reliability, risk reduction, or program execution.
Develop team capabilities that reduce dependence on individual engineers and improve organizational resilience.
