JOB TITLE

Buyer Instrumentation (10-15 Years Exp.)

KEY RESPONSBILITIES

• Buyer/ Procurement for instrumentation and control packages, including field instruments, analyzers, automation hardware, DCS/PLC components, SIS, control valves, and instrumentation consumables.
• Develop RFQ packages based on MR, instrument index, datasheets, P&IDs, I/O lists, cable schedules, and project control philosophies.
• Conduct techno-commercial evaluations (TBE/CBE) with Instrumentation & Control Engineering teams, focusing on accuracy class, measurement principle, SIL requirements, hazardous area classification, and lifecycle serviceability.
• Manage procurement of long-lead critical instrumentation such as gas analyzers, flow meters, radar level transmitters, vibration monitoring systems, actuator assemblies, and control modules.
• Coordinate procurement interfaces with Electrical, Mechanical, and Piping teams for HAZOP recommendations, IO expansions, sample conditioning systems, manifolds, hook-ups, and cabinet requirements.
• Execute PR to PO lifecycle within ERP (SAP/Oracle/Ivalua/MS Dynamics) ensuring complete documentation, technical compliance, vendor qualification, and controlled approval workflow.
• Work with OEMs/authorized system integrators, ensuring alignment to performance guarantees, firmware/hardware compatibility, cyber security policies, and lifecycle support.
• Drive instrumentation vendor onboarding, qualification, and risk evaluation for reliability, calibration infrastructure, FAT facilities, and site deployment capability.
• Coordinate QA/QC & FAT activities, including calibration certificates, benchmark test results, ATEX/IECEx compliance, hazardous class certification, loop checks, and ITP/QAP approvals.
• Conduct commercial negotiations on pricing, delivery, warranties, AMC support, software licensing, lifecycle consumables, LD clauses, and preventive-maintenance spares.
• Support engineering changes and HAZOP actions, incorporating new instrument ranges, installation philosophy, hook-up standards, and integration needs.
• Monitor vendor execution milestones, production readiness, dispatch plans, shipping documents, and commissioning assistance commitments.
• Support instrumentation planning, budgeting & estimation, providing cost benchmark data, supplier lead time insights, and category risk mapping.
• Maintain comprehensive procurement records including calibration certificates, CCoE certifications, hazardous-area approvals, FAT reports, O&M manuals, as-built documentation.
• Mentor junior buyers, ensuring procedural discipline and category knowledge transfer.
• Ensure KPI delivery - OTIF, PO cycle time, engineering TBE SLA, AMC cost control, and vendor performance scorecard.

FUNCTIONAL SKILLS

• Strong knowledge of instrumentation technologies: pressure/ flow/ temperature/ level transmitters, vibration monitoring, analyzers, actuators, control valves, switchgear interfaces.
• Understanding control system architecture: DCS/PLC/SCADA, ESD/SIS, IO modules, networking, cybersecurity protocols.
• Experience interpreting P&IDs, instrument index, hook-up drawings, cable block diagrams, panel layouts.
• Expertise in TBE/CBE for instrumentation, OEM comparison, and long-term operability.
• Familiarity with standards and certifications: IEC/ISA/API/ATEX/IECEx/SIL, IP ratings, hazardous area codes.
• Exposure to verification & FAT workflows: calibration, loop checks, functional tests, validation.
• ERP-driven procurement execution and documentation.

BEHAVIOURAL SKILLS

• Strong stakeholder alignment with Instrumentation, Electrical, QA/QC, Commissioning and Project Controls teams.
• Problem-solving mindset with analytical depth and technical curiosity.
• Cross-functional communication and vendor relationship maturity.
• Calmness under commissioning deadlines and change-handling agility.

QUALIFICATION

• Diploma / B.E. / B.Tech. in Instrumentation / Electronics / Electrical & Instrumentation / Control Engineering.

EXPERIENCE
