Senior Mechanical Design Engineer - Defence

ABOUT CRA

At CRA, we're creating purpose-engineered solutions that power the Energy and Defence sectors. As an integrated engineering powerhouse, we design, engineer, and manufacture everything in-house — giving us unmatched control over quality and innovation. Our solutions are trusted by industry leaders including BrahMos Aerospace, ONGC, OIL, Indian Airforce, and Schlumberger.

We've entered an extraordinary growth phase — tripling in size over the last three years. Today, with 100+ professionals, we're positioned at the intersection of two rapidly expanding sectors.

As Senior Mechanical Design Engineer – Defence, you will independently own complete mechanical and piping design packages for defence projects — from concept through fabrication-ready drawings. You will bring deep expertise in mechanical and piping design for defence-sector equipment, lead design reviews, and act as the technical design authority on your projects, reviewing and guiding the work of associate and junior designers.

This role is suited to an experienced design engineer who can independently drive design packages for complex, mission-critical equipment, resolve cross-functional design issues, and mentor junior designers.

• Independently own end-to-end mechanical and piping design packages for assigned defence projects — from concept through detailed fabrication drawings
  
• Lead 3D modelling of complex equipment (skids, ducts, enclosures, flares, burners) and piping systems, ensuring layout practicality and spatial coordination
  
• Produce and approve 2D manufacturing drawings — fabrication drawings, detailed part drawings, piping isometrics, and assembly drawings — with correct tolerancing and welding information
  
• Translate PFDs, P&IDs, and defence-specific technical requirements into mechanical/piping layouts with nozzle orientation, line routing, and support schemes
  
• Ensure design compliance with industry codes and defence project specifications (ASME B31.3, EN 13480, ISO tolerancing, and applicable defence/military standards)
  
• Develop and own structured BOMs, keeping them aligned with procurement needs and drawing revisions
  
• Lead advanced clash checks, fit-up simulations, and constructability reviews for complex assemblies
  
• Lead internal design reviews with QC, procurement, and production, and represent design in client-facing technical discussions on defence programmes
  
• Review associate and junior designers' drawings, providing technical redlines, guidance, and mentorship
  
• Drive continuous improvement in design standards, templates, and BOM practices
  
  
  

• Bachelor's Degree in Mechanical Engineering or related field
  
• 3–6 years of experience in mechanical/piping design, with substantial exposure to defence-sector projects
  
• Expert proficiency in both 2D and 3D CAD design for mechanical and piping systems
  
• Deep expertise in mechanical/piping standards, fabrication methods, and BOM practices, including defence-specific design and documentation requirements
  
• Proven track record of independently owning design packages for complex equipment, from concept to fabrication-ready drawings
  
• Strong knowledge of GD&T, weld symbols, pressure design basics, and assembly logic
  
• Experience reviewing and mentoring associate or junior designers
  
• Strong ownership of output accuracy and ability to coordinate across disciplines
  
• Comfortable working under schedule constraints and client-driven requirements, including defence documentation and compliance protocols.
  
  
  
  

• Competitive compensation package
  
• Generous leave policy
  
• Comprehensive group medical insurance
  
• Professional development opportunities and a dedicated training budget
  
• Regular performance reviews with clear advancement criteria into senior design leadership roles
  
• Exposure to industry leaders and cutting-edge defence programmes
  
• Collaborative and innovative work environment
  
• Opportunity to lead design on meaningful, mission-critical projects
  
• Recognition programs for exceptional contributions
  
• Team events and activities to foster a strong company culture
