About the Company
We are an early-stage deep-tech startup building cutting-edge AI-driven hardware + software systems for vision-based autonomy in robotics. Our solutions are deployed in Defence and Aerospace applications, designed to operate in harsh and mission-critical environments. We are engineering the next generation of visual autonomy through ultra-compact, ultra-reliable multi-spectral payloads featuring onboard video processing, jitter stabilization, and intelligent perception. If youre excited about pushing the boundaries of autonomous robotics and building real impact-driven technology, youll thrive here.
We are hiring a mid-level Mechanical/Product Design Engineer to develop and refine mechanical structures for camera gimbal payload systems used in drones. The role is fully onsite at our Pune office and involves hands-on design, prototyping, and collaboration with multidisciplinary engineering teams.
Key Responsibilities
- Design mechanical components and assemblies for 2-axis / 3-axis gimbal-stabilized camera systems
- Create structural designs for brackets, enclosures, linkages, isolation mounts, precision subassemblies
- Execute tolerance stack-ups and GD&T for tight-tolerance mechanisms
- Conduct structural, vibrational, and thermal assessments for airborne applications
- Prototype mechanical designs using rapid fabrication methods
- Work closely with electronics, optics, and embedded teams for integrated system design
- Prepare technical drawings, BOMs, assembly instructions, and specifications
- Collaborate with manufacturing partners and fabrication shops
- Maintain design documentation through PDM/PLM tools
Qualifications & Experience (Must Haves)
- Bachelors in Mechanical Engineering / Product Design / Mechatronics (Masters is a plus)
- 36 years mechanical design experience with precision mechanisms or moving assemblies
- Proficiency with CAD tools (Solidworks/Fusion360/CATIA)
- Strong knowledge of GD&T and dimensional tolerance design
- Experience with FEA or simulation tools (modal, vibrational, structural)
- Hands-on prototyping experience (3D printing, CNC, machining)
- Understanding of servo mechanisms, mechanical balancing, system dynamics, component selection
- Ability to translate engineering requirements into functional mechanical solutions
Experience (Good to have)
- Experience building gimbals, camera stabilizers, robotics, or drone payloads
- Deep understanding of lightweight, high-strength material selection (e.g., aerospace-grade aluminium, magnesium alloys, CFRP/composites) for weight-constrained systems.
- Experience with vibration damping and stabilization for motion systems
- Familiarity with weather-sealing for IP-rated enclosure design and ESS standard compliance.
- Understanding of camera modules, cable routing, PCB mounting, and thermal dissipation
Soft Skills
- Strong problem-solving ability
- Detail-oriented and quality-focused mindset
- Independent contributor with strong ownership
- Excellent communication and teamwork skills
Why Join Us
- Exposure to cutting-edge technologies in Stabilized Drone Camera Payloads.
