Job Summary
Own and drive the analysis, modeling, and architectural design of Amazon Leo's communications system, from MATLAB-based simulations to interconnection strategies and trade studies that optimize capacity, cost, and performance.
- Lead system architecture and modeling efforts for Leo's communications network
- Develop and extend MATLAB simulations and link-budget analyses
- Communicate results to multi-disciplinary teams to influence key architectural decisions
Job Description
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
Requirements
- 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
- 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
Benefits
- health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
- 401(k) matching
- paid time off
- parential leave
