About the Role

We are looking for a Senior Engineer to lead planning, costing, and process control. Play a critical role in translating customer requirements into accurate and feasible job orders, ensuring alignment between design specifications and manufacturing capabilities.

You'll support quotation processes, interpret technical drawings, develop production routings, and take ownership of job releases. You'll also be the technical point of contact for material selection and non-conformance assessments, while mentoring junior engineers.

This is a hands-on engineering role for professionals who enjoy problem-solving, cross-functional collaboration, and continuous improvement.

Key Responsibilities

Costing and Quotation Support

  • Reviewing and support accurate job costing by analysing material, labour, and process costs.
  • Provide engineering input during customer quotation stages to ensure feasibility.

Technical Drawing Interpretation and Production Planning

  • Interpret complex technical and customer drawings, translating them into clear engineering specifications.
  • Ensure all drawings are reviewed for accuracy, completeness, and manufacturability before production planning.
  • Promptly identify and submit inquiries for any discrepancies, ambiguities, or missing information found in drawings.
  • Proactively follow up on submitted queries to ensure timely resolution and prevent production delays.
  • Maintain clear and traceable records of all technical communications, clarifications, and drawing revisions.
  • Create accurate Bills of Materials (BOM) and develop structured production process plans using the ERP system.
  • Prepare complete and production-ready drawings aligned with internal manufacturing capabilities and standards.

Job Firm and Job Release

  • Take full ownership of job firming and release, ensuring alignment with production schedules and capabilities.
  • Serve as gatekeeper for job readiness – validating quality, completeness, and feasibility before release.

Materials Sourcing and Recommendations

  • Evaluate customer material specifications and recommend suitable material and substitutes.
  • Justify material choices based on technical fit, machinability, and manufacturing risk.

Non-Conformance Management (SPR and MRB)

  • Support the resolution of lower-risk non-conformance issues through structured technical assessments.
  • Recommend adjustments, escalate when needed and assist in documentation of Source Problem Report (SPR).
  • Investigate minor internal errors, propose corrective actions, and assist in preparing documentation for Material Review Board (MRB).
Who are we looking for?

Required Qualifications and Experience

  • Polytechnic Diploma or higher in Engineering (Advanced & Digital Manufacturing, Mechanical, Mechatronics)
  • Minimum 5 years' experience in a high-mix, low-volume manufacturing environment.

Strong working knowledge of:

  • Manufacturing Processes: Skilled in assessing job complexity and determining appropriate machining methods (eg. 3-, 4-, or 5-axis) based on part geometry and tolerances.
  • Material Knowledge: Deep understanding of material types, grades, and their impact on machining and component performance; able to recommend substitutes based on production needs.
  • Drawing Interpretation: Proficient in translating complex customer drawings—including weldments and critical features—into clear, production-ready documentation.
  • ERP & Planning: Experienced in generating accurate BOMs, routings, and process flows within ERP systems to meet production and customer requirements.

Proven ability to:

  • Assess and release job packages to meet production readiness standards.
  • Recommend material options based on availability, machine capabilities, and performance requirements.
  • Support resolution of non-conformance issues (SPRs/MRBs) with sound engineering judgment.

Preferred Attributes

  • Hands-on experience with CNC machining and precision measurement tools.
  • Strong stakeholder management capabilities, with the ability to collaborate effectively across functions and engage confidently in client-facing situations.
  • Prior experience working in a matrix management structure, with demonstrated ability to coordinate and align with colleagues from multiple departments (e.g., Business, Production, Quality, Supply Chain).
  • Demonstrated mentoring skills, with a proactive mindset toward learning, development, and continuous improvement.
