Communications Engineer, Simulation and Modeling

Key job responsibilities

• Work within a project team and take the responsibility for the Leo's overall communication system design and architecture
• Extend existing code/tools and create simulation models representative of the target system, primarily in MATLAB
• Design interconnection strategies between fronthaul and backhaul nodes. Analyze link availability, investigate link outages, and optimize algorithms to study and maximize network performance
• Use RF and optical link budgets with orbital constellation dynamics to model time-varying system capacity
• Conduct trade-off analysis to benefit customer experience and optimization of resources (costs, power, spectrum), including optimization of satellite constellation design and link selection
• Work closely with implementation teams to simulate expected system level performance and provide quick feedback on potential improvements
• Analyze and minimize potential self-interference or interference with other communication systems
• Provide visualizations, document results, and communicate them across multi-disciplinary project teams to make key architectural decisions

Basic Qualifications

• Master's degree in computer science, electrical engineering, automation engineering, or equivalent
• 5+ years of work in satellite system design, modeling, and analysis, or equivalently complex, time-dynamic systems.
• 4+ years of work developing code in Matlab, and experience with industry standard coding and regression practices
• Experience conducting and documenting trade studies and design trades.
• Good analytical, problem solving, and communication skills
• Must have the ability to work in a small team and drive to go beyond expectations to deliver results.

Preferred Qualifications

• PhD in Aerospace Engineering, Electrical Engineering, Computer Science, related discipline, or equivalent experience
• Familiarity with satellite systems and operations
• Familiarity with satellite constellation design and management trades
• Experience modeling orbits, reference frames, and efficiently using vector geometry to simulate time-varying relative geometry of satellites and ground nodes.
• RF or Communications System design background or solid understanding
• Experience in wireless system design and architecture, system integration, RF system analysis, including use of link budgets for modeling
• Experience with graph theory, bin-packing, network topology analysis, or other applied techniques relevant to NP-hard resource allocation problems
• Some experience with C++ or Python.
