ESSENTIAL DUTIES AND RESPONSIBILITIES or KEY ACCOUNTABILITIEs Lead continuous improvement initiatives for the Apollo humanoid robot, identifying and addressing design and manufacturing bottlenecks. Conduct root cause analysis on system failures, performance issues, and production inefficiencies to implement robust solutions. Collaborate with cross-functional teams, including electrical, software, and manufacturing engineers, to integrate improvements seamlessly. Optimize mechanical designs for manufacturability, reliability, and cost-effectiveness. Design, prototype, and test new components and sub-systems to enhance overall robot performance. Develop and implement best practices for mechanical assembly, testing, and quality control. Document all design changes and improvements thoroughly, ensuring clear communication and knowledge transfer. Mentor and provide technical guidance to junior engineers. SKILLS AND REQUIREMENTS Expertise in CAD software (e.g., SolidWorks, CATIA, or similar) and FEA simulation. Strong understanding of GD&T, tolerance analysis, and manufacturing processes like CNC machining, 3D printing, and injection molding. Hands-on experience with prototyping and testing, including the use of lab equipment. EDUCATION and/or EXPERIENCE Bachelor's degree in Mechanical Engineering or a related field; Master's degree preferred. 7+ years of experience in a mechanical engineering role, with a strong focus on design for manufacturing, and continuous improvement. Proven experience with complex electromechanical systems, particularly in robotics, aerospace, or a similar field. Excellent problem-solving skills and a data-driven approach to decision-making. Effective communication skills and the ability to work collaboratively in a fast-paced environment. Experience with humanoid robotics or legged locomotion is a significant plus. PHYSICAL REQUIREMENTS Prolonged periods of sitting at a desk and working on a computer Must be able to lift 15 pounds at times Vision to read printed materials and a computer screen Hearing and speech to communicate *This is a direct hire.

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.
