About the Role

We are seeking a detail-oriented and commercially astute Tender & Bidding Assistant Manager to support the growth of RMA Special Vehicles. The role will manage the end-to-end tender and bidding process for specialised vehicle solutions across government, defense, corporate and institutional customers, ensuring submissions are technically compliant, commercially competitive and delivered on time.

The successful candidate will be a proactive bid owner, not simply a document coordinator: capable of interpreting complex requirements, challenging assumptions, driving cross-functional inputs and supporting disciplined bid/no-bid decisions. The role will help improve bid quality, conversion and profitability across our international Special Vehicles business.

Location

The position is based in Laem Chabang, Thailand, working closely with sales, engineering, costing, customer service, purchasing, production, finance and legal teams as well as modification centres in other countries.

Identify tender exceptions and commercial, contractual, regulatory and delivery risks; escalate material issues before submission.

Stakeholder Coordination & Continuous Improvement

Liaise with tendering authorities, customers, consultants and partners on clarifications, pre-bid meetings and post-submission follow-up.

• Coordinate with internal functions and external suppliers to validate technical scope, lead times, compliance and execution readiness.

• Track bid outcomes, maintain lessons learned and competitor intelligence, and improve tender templates, processes and bid conversion performance.

Support the handover of successful bids to project execution teams, ensuring key commitments and assumptions are documented.

Background and Experience

Bachelor's degree in Engineering, Business, Commerce or a related discipline.

• Demonstrated experience in tender management, bid preparation or proposal coordination, ideally for automotive, specialised vehicles, engineering, industrial equipment or complex B2B projects.

• Working knowledge of government/public-sector procurement procedures, tender documentation, compliance matrices and electronic tendering platforms.

• Strong commercial acumen, including the ability to interpret cost estimates, pricing structures, margins and contractual risks.

• Ability to understand technical specifications and coordinate effectively with engineering, production, procurement and finance teams.

• Excellent planning, analytical, documentation and stakeholder-management skills, with exceptional attention to detail and deadlines.

• Strong written and spoken English;
