Job Description

Job Title: Sr. Mechanical Design Engineer, Precision Motion & Gimbal Systems(UAV)

Location: Pune (Onsite)

Employment Type: Full-time

Experience Level: Mid-Level (36 years)


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.
  • Competitive compensation aligned with deep-tech talent market
  • Flexible work timings while maintaining onsite presence
  • Opportunity to work closely with founders and core engineering leadership
  • Merit-based growth and accelerated learning curve
  • Strong ownership of product areas and decision-making autonomy
  • Exposure to cutting-edge robotics, autonomy, and defence-grade hardware developments
  • Meaningful work with real-world impact in national security and advanced robotics.
