Job description

Role Purpose

The AutoCAD Draughtsman turns engineering designs and customer specifications into accurate, production-ready drawings for SigmaFlow's valves used in water and wastewater projects. The role supports tendering, customer approvals, shop-floor manufacturing and quality inspection, so drawings must be precise, standards-compliant and delivered on time.

Key Roles and Responsibilities

Drawing preparation

• Prepare 2D general arrangement (GA) drawings, part drawings, assembly drawings and sectional views for valves such as Gate Valves, Butterfly, Check/Non-return, Air valves, Diaphragm and Control valves.
• Prepare casting drawings and pattern drawings for foundry suppliers.
• Draw bills of materials (BOMs) and parts lists, and keep them aligned with item codes.

Project and tender support

• Prepare customer approval drawings and datasheets for Municipal, EPC and Industrial water/wastewater projects, as per tender specifications.
• Incorporate consultant and customer comments quickly and resubmit revised drawings within committed timelines.
• Prepare actuator mounting, gearbox and accessory arrangement drawings, including Flange drilling details (IS, ANSI/ASME B16.5, EN 1092, AWWA).
• Support the sales and proposal teams with dimensional drawings for quotations.

Manufacturing and quality support

• Issue released drawings to production, purchase, quality and vendors and clarify drawing queries on the shop floor.
• Prepare inspection and test drawings and support QA with dimensional references for inspection and third-party inspection (TPI).
• Update drawings based on field feedback, NCRs and design improvements.

Documentation and drawing control

• Maintain drawing numbering, revision control and change records as per the company's document control system.
• Keep the drawing library, standard parts and templates organized and up to date.
• Follow title block, layering and drafting standards consistently across all drawings.
• Coordinate with design engineers on 3D models and extract 2D drawings where required.

Desired Candidate Profile

Education

• Diploma in Mechanical Engineering (preferred), or ITI (Draughtsman Mechanical) with strong relevant experience.
• Certification in AutoCAD from a recognized institute is an advantage.
• 5-10 years of experience in mechanical engineering or a related field with expertise in valve design and drafting.
• Diploma/B.Tech / B.E. degree in Any Specialization; knowledge of AutoCAD Mechanical preferred but not mandatory.
• Strong understanding of industrial valve systems, materials science, and relevant industry standards (ASME B31.1).
• Proficiency in creating complex drawings using AutoCAD software; ability to work independently with minimal supervision.

Experience

• 4-10 years as a mechanical draughtsman in a manufacturing company.
• Experience with valves, pumps, pipe fittings or flow-control equipment is strongly preferred.
• Exposure to water and wastewater, municipal or EPC project documentation is an added advantage.

Technical skills

• Advanced proficiency in AutoCAD 2D; working knowledge of 3D modelling (SolidWorks, Inventor or Creo) is preferred.
• Sound understanding of engineering drawing practice, orthographic projections, sectioning, GD&T, fits and tolerances, and welding symbols.
• Familiarity with valve and flange standards such as IS14846, IS 13095, IS 1538, AWWA C504/C509, API 609, ASME B16.5 and EN 1092.
• Basic knowledge of materials (CI, DI, CS, SS), casting and machining processes.
• Comfortable with MS Excel for BOMs and drawing registers; ERP exposure is a plus.

Personal attributes

• High attention to detail and accuracy.
• Able to handle multiple projects and revisions under tight deadlines.
• Good communication in English and Hindi/Bengali, for coordination with engineers, shop floor and vendors.
• Disciplined in documentation and revision control.
