As a Senior Prototyping Engineer – Hybrid Power & Fuel System Integration, you will become an integral part of our Prototyping team, supporting the development of our Reliant platform – a next-generation long-range eVTOL unmanned aerial system designed for demanding ISR and logistics missions. Reliant combines exceptional endurance, modularity, and operational flexibility to deliver mission-critical capabilities in the most challenging environments. In this role, you will take ownership of the integration, development, and validation of the aircraft's hybrid power generation system, including the internal combustion engine, fuel storage and delivery system, generator, and associated electrical and control interfaces. You will ensure reliable, safe, and efficient operation of the complete propulsion system throughout the prototype development cycle by working closely with mechanical, electrical, propulsion, avionics, and systems engineering teams. What is your Day to Day Mission: Lead the integration of the hybrid propulsion system, including the combustion engine, fuel system, generator, and power electronics into prototype aircraft. Develop and validate fuel storage, distribution, and delivery systems, including tanks, pumps, filters, valves, sensors, and plumbing. Design, build, and commission test rigs and dedicated test stands. Develop and execute functional, endurance, and performance test campaigns for fuel and hybrid power systems. Set up, integrate, commission, and troubleshoot combustion engines, generators, fuel systems, and associated control systems. Analyze system performance, efficiency, reliability, and failure modes, implementing design improvements based on test results. Collaborate closely with propulsion, mechanical, electrical, controls, and systems engineering teams to optimize system integration and aircraft performance. Prepare technical documentation, verification reports, test procedures, and engineering recommendations to support prototype development.

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.
