Salary :SGD 4,500 – SGD 6,000/month (Based on experience and technical capability).

Responsibilities:

1. Support design and prototype development

• Work with designers from the early design stage to identify purchasing requirements, sourcing risks and long lead-time components.

• Review BOMs with engineers and track items awaiting specifications, drawing release, quotation or purchase approval.

• Coordinate purchasing priorities with module owners and assembly teams so that parts arrive in the sequence needed for each build.

• Respond promptly to design changes and manage their impact on open orders, delivery dates and costs.

2. Resolve difficult sourcing situations

• Proactively source mechanical, electrical, motion control, pneumatic, vacuum and other equipment components, together with custom fabricated parts.

• Identify alternatives when specified parts have excessive lead times, become obsolete, are unavailable or cannot meet project requirements.

• Present engineers with practical options, including available stock, alternative brands or models, local fabrication and expedited delivery.

• Obtain engineering approval for all technical substitutions before committing purchases.

3. Own supplier follow-up and delivery

• Provide a concise critical-parts update showing what could delay each module and the action being taken.

• Ensure suppliers receive the correct drawings and revisions; manage order amendments, cancellations and obsolete stock exposure following design changes.

• Coordinate with receiving, quality and engineering teams to resolve incorrect, damaged or nonconforming deliveries.

Requirements:

• Diploma or degree in engineering, supply chain, procurement or a related discipline; relevant practical experience will also be considered.
