Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity. As an Amazon Leo Interdisciplinary RF Test System Engineer, you will own the full lifecycle of complex RF test systems and hardware development for spacecraft avionics and payload sub-systems. Your responsibilities span hardware and software development activities, RF test, system-level architecture, calibration support, and test system BOM-level CAD design. You will serve as the Responsible Engineer (RE) for your test set, operating at the intersection of hardware development, RF system verification, Space qualification testing, test automation, and high-rate manufacturing. You should be comfortable with a high degree of ambiguity and relish the idea of solving problems that haven't been solved at scale before. You'll have relentlessly high standards for yourself and everyone you work with, and you'll be constantly looking for ways to improve. We want individuals who want to reach beyond what is possible today. Everyone on the team needs to be entrepreneurial, wear many hats, and work in a highly collaborative environment. 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 • Architect, design, build, and sustain RF test systems for satellite modems, transceivers, BUCs, LNBs, and ground equipment through design validation, qualification, production and on-orbit support • Support hardware and software development activities including RF subsystem design, integration, and characterization • Perform RF test system-level path loss calibration, link budget analysis, and end-to-end signal chain verification • Own test system BOM-level CAD design including rack layout, cable harness routing, mechanical fixture design, and documentation • Own test planning end-to-end: decompose verification requirements into testable specifications, develop test procedures, and lead test readiness reviews • Drive cross-functional alignment with electrical, mechanical, thermal, software, firmware, and manufacturing teams on verification strategy • Design and deliver test hardware, fixtures, and tooling that optimize throughput, yield, and fault coverage • Develop and maintain calibration procedures, path loss models, and measurement uncertainty budgets for RF test stations • Build quantitative models (test coverage, reliability, throughput) to inform design trade studies and process decisions • Automate and optimize test processes to meet production rate and first-pass yield targets • Perform root cause analysis on test failures, lead corrective actions, and drive continuous improvement of production test systems A day in the life Our time is balanced between critical support/improvement of existing factory test processes, hardware development activities, and designing future test systems. This includes hands-on support troubleshooting space flight hardware and test systems, CAD design for test system BOMs, and working to align teams around future needs, employing engineering best practices and tools, including AI. The tasks and daily focus change rapidly, and you will often take on exciting new responsibilities to ensure project success. Expect to address complex problems by diving deep into the data, identifying the scope of the issue, and creating innovative and functional solutions. About the team This Interdisciplinary Engineer will be a member of the Avionics Verification & Test team working within the wider RF Hardware Engineering team. This highly collaborative group of engineers has a diverse range of backgrounds and knowledge and works to build scalable and reliable test automation solutions and hardware development capabilities to ensure reliable operation of satellite vehicles in space. The team's responsibilities include process development, test hardware and software development, and test execution supporting our 24/7 satellite manufacturing factory.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
