• Coordinate with design, QA/QC, and supply chain teams

2. Technical & Process Control

• Interpret complex engineering drawings and API thread specifications (REG, IF, NC)
• Oversee precision machining of high‑strength alloy steels and non‑magnetic materials
• Supervise welding processes including hardfacing, carbide welding, PDC bit repairs, and fabrication
• Ensure compliance with AWS welding standards Approve machining setups and tooling selection.pdf)

3. Quality Assurance & Compliance

• Ensure compliance with API Spec 7‑1 and API Q1
• Monitor dimensional tolerances, surface finish, and thread quality
• Coordinate NDT activities (MPI, DPI)
• Review inspection reports and manage NCRs and corrective actions

4. Health, Safety & Environment (HSE)

• Enforce strict HSE policies
• Conduct risk assessments, toolbox talks, and safety audits
• Ensure safe handling of heavy components and hazardous materials
• Investigate incidents and implement preventive actions.pdf)

5. Team Leadership & Development

• Supervise machinists, CNC operators, welders, and technicians
• Provide technical guidance and training on API standards and best practices
• Conduct performance evaluations and manage productivity

6. Equipment & Maintenance

• Oversee maintenance of CNC, deep hole drilling, threading, and welding equipment
• Ensure calibration of measuring instruments
• Coordinate preventive maintenance to reduce downtime Improve tooling performance.pdf)

7. Materials & Inventory Control

• Manage high‑grade materials (4145H mod, Inconel, non‑mag materials)
• Monitor usage of cutting tools and welding consumables
• Coordinate procurement of critical materials and spares
• Reduce scrap and improve material utilization

8. Documentation & Reporting

• Maintain manufacturing records and material traceability
• Ensure proper WPS and PQR documentation
• Track KPIs (rejection rates, on‑time delivery, machine utilization)
• Prepare reports for management and audits

Required Qualifications

• Diploma or Bachelor’s degree in Mechanical / Manufacturing Engineering
• 7–12 years of experience in oil & gas downhole tools manufacturing
• Minimum 3–5 years in a supervisory role

Required Skills & Expertise

• Strong knowledge of API standards for downhole tools
• Expertise in CNC machining, deep hole drilling, and threading
• Hands‑on experience in hardfacing and wear‑resistant coatings
• Familiarity with NDT methods and quality systems
• Strong leadership and decision‑making skills
• Ability to work under pressure and meet tight deadlines
