Job description

Sr. Wireless Integration and Test Engineer, Amazon Leo

Job ID: 10585915 | Amazon Kuiper Manufacturing Enterprises LLC

Be part of the team defining and developing the overall communication system architecture and design of Amazon Leo’s wireless network. This is a unique opportunity to innovate and define ground-breaking wireless technology with few legacy constraints.

Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Key job responsibilities

• Work closely with implementation teams to evaluate and simulate expected system level performance and provide quick feedback on potential improvements
• Work with the PHY and Network teams to seamlessly integrate the link‑layer within the stack.
• Integrate the various link‑layers working closely with implementation teams.
• Verify link budget and RF line‑ups in RF and IF configurations.
• Create time synchronized setups with signal generators / spectrum analyzers and use these to verify timing budgets.
• Architect and document time/frequency/space acquisition and tracking algorithms. Understand Doppler pre and post compensation techniques with CFO/SFO in LEO comms systems. Experience with channel emulators is a plus.
• Work with a team to develop novel customized test plans using embedded programing to generate and capture waveforms in real‑time. Experience with software defined radios is highly preferred.
• Contribute development‑test bring up procedures with Linux, Python, bash scripting etc.
• Willing to work in a lab environment and on scripting to change a SW/HW pieces incrementally and understand its effect on payload (via probing RF, IF, clock, channel quality messages) with help of Spec‑an, sig‑gen, scope, frequency counter, attenuators and other related equipment.
