Professional Tender Engineer

About the Role Siemens Energy is seeking a Professional Tender Engineer in Indonesia to lead technical tendering and bid management for high-voltage substations, including AIS and GIS switchgear. You will translate customer requirements and RFPs into compliant, optimized turnkey or equipment-only solutions, working with internal engineering, procurement, and project teams to ensure feasible, cost-effective offerings. This role is part of the Grid Technologies Substations team and supports our Asia Pacific service network. What You'll Do

• Analyze customer technical specifications, RFPs, and single-line diagrams (SLDs) for AIS and GIS Substation projects to develop fully compliant, optimized, and competitive turnkey or equipment-only solutions.
• Prepare and manage the creation of detailed technical and commercial tenders, bids, and proposals for high-voltage substations up to utility-scale voltages.
• Collaborate with internal engineering (civil, structural, electrical), procurement, and project management teams to confirm design feasibility, footprint optimization, and accurate pricing.
• Define and document technical configurations, including switchgear (GIS/AIS), transformers, instrument transformers, surge arresters, and protection & control systems, aligning them with pricing considerations and contract requirements.
• Optimize layout designs (especially footprint reduction for GIS or clearances for AIS) in coordination with the design team to present the most cost-effective solution to the client.
• Prepare and conduct technical sales briefings, proposal presentations, and layout reviews for utility clients, EPCs, and industrial customer representatives.
• Develop and maintain strong relationships with key customer engineers and procurement stakeholders to understand their evolving grid requirements.
• Manage inbound customer inquiries, including technical Q&As, Requests for Information (RFIs), and pre-bid clarification meetings.
• Prepare detailed cost calculations, including Bill of Quantities (BOQ), commercial risk assessments, and quantification; coordinate with sub-vendors (e.g., civil contractors, control system integrators).
• Support the sales and business development teams with market intelligence, technical workshops, and customer care initiatives.
• Collaborate with business promoters, consortium partners, factories, and execution teams to optimize the technical and commercial offer, ensuring a winning strategy aligned with customer drivers.
• Manage tendering projects and complex turnkey substation processes independently, navigating challenging regulatory, environmental, or grid-code requirements with limited supervision.
• Track market trends regarding eco-efficient alternative gases for GIS, and standard utility practices to position proposals strategically. What We're Looking For
• Bachelor's degree in Electrical Engineering, Power Systems, or a related technical discipline.
• Proven experience (typically 5–8 years) in technical sales, tendering, application engineering, or primary/secondary design within the HV substation industry.
• Demonstrated experience and in-depth knowledge of AIS and GIS switchgear, substation layouts, and auxiliary systems. Familiarity with civil/structural constraints and protection & control (P&C) concepts is highly desirable.
• Mastery of Bid & Proposal Management, BOQ estimation, risk matrix evaluation, and technical writing.
• Strong communication skills for relationship building, technical negotiations, and resolving pre-bid clarifications.
• Ability to analyze competitor positioning, optimize cost structures for EPC bids, and apply strategic thinking to maximize win rates. Nice to Have
• Familiarity with civil/structural constraints and protection & control concepts is highly desirable. Compensation & Benefits
• Be a trusted advisor to both internal and external stakeholders.
• Develop your technical and soft-skills working with cross-functional teams.
• Numerous further training opportunities (technical, soft skills, etc.) are available to you on the Siemens Energy Learning platform.
