Role Overview

We are seeking a Mechanical Design Engineer to join our core product engineering team. In this role, you will own the design, analysis, and validation of robots and peripheral structures across the entire product lifecycle—from proof-of-concept through production and sustaining phases. You will collaborate closely with embedded, controls, software, and operations teams, as well as external vendors, to bring robust, scalable, and manufacturable robotic solutions to life. The ideal candidate is a hands-on engineer with a strong foundation in first-principles calculations, CAD modelling (preferably Solid Edge), FEA, multibody dynamics, and GD&T, and has 2–5 years of experience in product development within a startup or high-paced environment.

Key Responsibilities

• Design robots and peripheral structures across the full product range (POC through production and sustaining) in alignment with cross-functional engineering teams.
• Perform aggregate calculations and select appropriate components and materials.
• Create accurate CAD part and assembly models and drawings, including tolerance stack-up analysis where needed.
• Conduct structural analysis and multibody dynamics simulations to validate designs against performance, safety, and reliability targets; define correct FEA inputs and interpret results to guide design decisions.
• Develop test cases, set up test environments, execute tests, and prepare detailed test reports.
• Based on test outcomes, identify improvement areas, propose design modifications, and plan iterations or further testing until requirements are met.
• Communicate design intent to vendors using 3D CAD, 2D drawings, GD&T, and engineering specifications, applying DFM and DFA principles.
• Work with vendors and suppliers to develop and scale components to specification.
• Collaborate with embedded, controls, and software teams for seamless integration, and with operations teams on sourcing, QC, assembly, and delivery.
• Develop and maintain BoMs, SOPs, release notes, change records, and validation reports.
• Support root-cause analysis and corrective actions for mechanical issues across prototypes, production, and field returns.

Tech Stack

• CAD Software: Solid Edge (preferred), general CAD modelling.
• Simulation Tools: Ansys (FEA), Adams (multibody dynamics).
• Engineering Standards: GD&T, tolerance stack-up analysis, DFM/DFA, FMEA.
• Documentation: BoMs, SOPs, test reports, release notes, change records.
• Cross-disciplinary: Basic understanding of electronics, controls, and software integration.

• Strong capability in aggregate calculations and first-principles problem-solving on complex mechanical challenges.
• Expertise in CAD, preferably Solid Edge, producing accurate, high-quality models efficiently.
• Deep knowledge of GD&T and proficiency in tolerance stack-up analysis.
• Hands-on structural analysis and multibody dynamics experience with tools such as Ansys and Adams.
• Strong working knowledge of manufacturing processes such as machining, sheet metal, casting, and welding across multiple materials, and their impact on design decisions.
• Hands-on experience designing primary structures, mechanisms, jigs, and fixtures.
• Working knowledge of solid mechanics, load cases, and failure mechanisms.
• Proven experience producing detailed documentation (BoMs, SOPs, test reports, change records).
• Familiarity with Design Thinking principles for ideation, problem-solving, and product design.
• Strong written and verbal communication and the ability to coordinate across multiple stakeholder teams.
• Experience conducting FMEAs and building and executing design validation test plans (good to have).
• Familiarity with relevant Indian and international standards and compliance regulations for industrial machinery and automated systems (good to have).
• Certified courses in Design Thinking (good to have).
• Cross-discipline knowledge of electronics, controls, or software (good to have).
• Familiarity with data analysis and visualisation (good to have).
