Mechanical Design Engineer

About This Role

You will be responsible for leading Design and Development of mechanical systems for our cutting-edge defence products.

We are seeking a Mechanical Design Engineer who thrives on owning projects end-to-end—from ideation to deployment. As a Mechanical Design Engineer, you'll work on actual hardware from day one — designing, prototyping, testing, and breaking things that the Armed Forces might use tomorrow. You’ll be part of the R&D team behind our next-gen defence products, contributing to everything from sketches to field tests.

What You’ll Be Doing

• Brainstorm & sketch concepts based on first principles (we don’t do copy-paste design).
• Design 3D models and detailed mechanical parts using SolidWorks or Fusion 360 considering DFM, DFMEA, DFA.
• Rapid prototype using 3D printers, CNC Milling, and other machines in our in-house R&D lab.
• Work closely with electronics and software teams to bring hardware to life.
• Break your designs, fix them fast, and learn even faster.
• Analyze and Simulate the models in ANSYS and MATLAB
• Test and validate prototypes as per MIL STDs

Requirements

• 2–5 years of experience in mechanical new product development.
• Proficiency in CAD software (e.g., SolidWorks, Fusion 360) and simulation tools (e.g., Ansys, MATLAB).
• Strong understanding of materials, tolerances, and manufacturing processes such as CNC machining, and 3D printing.
• Excellent problem-solving and analytical skills.
• Passion for hands-on projects — show us what you’ve built!

Read Before Applying

• We are looking for candidates with experience in product development startups or industries (not service-based industries).
• Candidates available to join within 1 week -15 days will be preferred.
• What we’re building demands hard work, tenacity, ownership, creativity, and significantly more man-hours than an average job. If you prefer routine over the dynamic unpredictability of innovation, Astr isn't for you. Our fast-paced environment requires curiosity, resilience, a passion for continuous learning, and comfort with rapid change.

Read Before Applying

This won’t be easy.

You’ll break things, fix them, burn midnight oil, and still stay hungry.

But it’ll be one hell of a ride.

If you want a comfy job or like following SOPs more than challenging them — this isn’t for you.

But if you're wired to solve problems under pressure and chase real impact, welcome aboard.

Why You SHOULD Join Us

• Get your hands dirty solving real defence problems
• Work with crazy smart A-players across disciplines
• Design, build, test — rinse and repeat
• Do work that matters — for national security

What You’ll Get

• A hardcore learning environment
• Crazy levels of ownership
• Freedom to experiment, fail, learn, and ship
• The satisfaction of building something that actually works in the field
