• Perform waveform, capacity, coverage, and network performance analyses using advanced simulation and analytical tools.
• Apply digital communications and signal processing principles, including modulation schemes, Forward Error Correction (FEC), and industry-standard waveforms such as DVB-S2/S2X, PTW, and W-CDMA.
• Conduct detailed link budget and link closure analyses, accounting for interference, nonlinear effects, jamming environments, and mission-specific operational constraints.
• Evaluate communications performance across diverse orbital and mission scenarios.

System-of-Systems Analysis & Optimization

• Execute constellation-level trade studies to assess performance, coverage, throughput, and operational effectiveness.
• Analyze and optimize resource allocation across large-scale space architectures, including RF spectrum, transmit power, onboard storage, and scheduling priorities.
• Support mission planning activities through quantitative modeling and performance forecasting.
• Develop optimization strategies that balance technical performance, operational requirements, and program objectives.

Systems Engineering & Integration

• Translate complex subsystem interactions and constraints into actionable engineering analyses and design recommendations.
• Collaborate with communications, software, aerospace, and systems engineering teams to ensure high-fidelity modeling and simulation accuracy.
• Contribute to architecture development, requirements definition, and system performance assessments.

Software Development & Model Validation

• Develop, maintain, validate, and enhance simulation tools, analytical models, and engineering software applications.
• Review and verify modeling assumptions, algorithms, and analytical results to ensure technical accuracy.
• Support software configuration management and collaborative development environments using Git, GitLab, and modern development practices.

Data Visualization & Technical Communication

• Create impactful visualizations, interactive dashboards, and mission performance presentations to communicate complex technical data.
• Present engineering analyses, recommendations, and trade study results to technical and program stakeholders.
• Develop graphical products and mission concept visualizations that support decision-making and customer engagements.

Required Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, Computer Science, Physics, Mathematics, or a related technical discipline.
• Strong background in digital communications and Digital Signal Processing (DSP).
• Experience in satellite communications, systems engineering, space systems analysis, constellation design, or modeling and simulation.
• Proficiency in Python and/or MATLAB for scientific computing, modeling, and data analysis.
• Understanding of RF communications, link budgets, coverage analysis, orbital visibility, and space system performance evaluation.
• Experience conducting technical trade studies and analyzing complex engineering systems.
• Excellent analytical, problem-solving, and communication skills.

Preferred Qualifications

• Proficiency in both Python and MATLAB, including software development best practices.
• Experience with government or commercial SATCOM systems and architectures.
• Knowledge of constellation resource management, mission planning, and optimization algorithms.
• Experience developing, extending, or modernizing modeling and simulation frameworks.
• Familiarity with Git, GitLab, CI/CD workflows, and collaborative software development environments.
• Experience creating advanced technical visualizations, animations, or mission analysis products for space programs.

Education & Experience

• Bachelor's degree with 9+ years of relevant experience, or
• Master's degree with 7+ years of relevant experience, or
• Ph.D. with 4+ years of relevant experience.
• Degree in Engineering, Computer Science, Mathematics, Physics, Chemistry, or a related STEM discipline from an accredited institution.
  
  
• Medical, dental, and vision insurance are available to qualified candidates who meet eligibility requirements.
