How You'll Contribute

Technical Leadership & Sourcing

• Lead the technical evaluation of complex parts, assemblies, and projects, and set the standard for how complexity is assessed across the team
• Review drawings, specifications, and project documentation to identify key manufacturing risks, tolerances, materials, and process requirements
• Guide the sourcing team in selecting suitable manufacturing processes, capabilities, and providers for high-complexity or strategic projects
• Own the technical tagging framework: define, maintain, and audit tags so that parts and requirements are categorized accurately and consistently

Quotation & Critical Deal Support

• Act as the final technical reviewer for complex or high-value quotations, checking completeness, accuracy, and alignment with customer requirements
• Identify technical gaps, risks, and ambiguities early, and drive their resolution with the relevant teams
• Provide technical input and manufacturing expertise on critical deals, escalations, and strategic customer projects

Client & Provider Communication

• Lead or join technical meetings with clients and manufacturing providers to clarify requirements, propose alternatives (DFM feedback), and resolve technical challenges
• Present technical information clearly to both technical and non-technical stakeholders, including management
• Ensure alignment between customer expectations, provider capabilities, and the final sourcing solution

Team Leadership & Mentoring

• Coach, mentor, and develop Sourcing Engineers, providing technical guidance, code and drawing review practices, and constructive feedback
• Support onboarding and training of new team members
• Help prioritize and distribute workload across the team during peak periods
• Build and maintain a knowledge base of best practices, lessons learned, and technical guidelines

Process Improvement & Cross-Functional Collaboration

• Partner with engineering, sourcing, sales, quality, and operations teams to support successful project execution
• Identify bottlenecks and inefficiencies in sourcing and quotation workflows, and lead continuous improvement initiatives
• Contribute to the evaluation and development of tools, automation, and data used in technical assessment
• Track and report key team metrics (e.g., quote accuracy, turnaround time, tagging quality) and act on the findings

• Sourcing Experience: Proven experience working with suppliers, manufacturers, and cross-functional sourcing and engineering teams
• Leadership: Ability to guide, motivate, and develop technical colleagues, and to make sound decisions on ambiguous or high-risk projects
• Communication: Excellent written and verbal communication skills; confident in discussing technical requirements with clients, providers, and internal stakeholders
• English: B2 level or higher
• Problem Solving: Strong analytical skills and the ability to resolve complex technical and commercial challenges
• Organization: Ability to manage multiple projects and priorities in a fast-paced environment
• Collaboration: Strong interpersonal skills and the ability to influence across engineering, sourcing, sales, and operations
• Adaptability: Calm under pressure, flexible with changing priorities, and attentive to detail

Nice to Have

• Experience with ERP/quoting platforms, CAD viewers, or marketplace/on-demand manufacturing models
• Familiarity with quality standards (ISO 9001, AS9100, IATF 16949) and inspection methods
• Experience working with data or automation to improve technical evaluation
