Requirements
• 8+ years of experience in manufacturing, assembly engineering, industrialisation, or production engineering in complex hardware environments • Strong hands-on experience with precision assembly and integration for advanced electro-mechanical or opto-electronic hardware products • Proven experience owning and improving assembly processes across prototype, NPI, and early production ramp environments Experience with substrate-level or package-level assembly, including flip-chip bonding processes (attach, reflow, underfill, inspection) • Solid understanding of DFM/DFA principles and the ability to translate engineering designs into robust, repeatable manufacturing processes • Experience creating and maintaining manufacturing documentation — work instructions, • SOPs, process flows, BoMs, and build records • Hands-on experience with tooling, fixtures, jigs, and line setup for precision assembly operations • Strong problem-solving capability with a track record in root cause analysis, yield improvement, and corrective action
Responsibilities
• Assembly Process Engineering & NPI • Define and own assembly processes for complex electro-mechanical and opto-electronic module hardware, from early prototype builds through NPI and into production Create and maintain manufacturing documentation including assembly instructions, work standards, process flows, and build records Drive DFM/DFA reviews with engineering teams to ensure designs are practical, repeatable, and cost-effective to buildOwn assembly processes for substrate-level flip-chip bonding (FCB), including attach, reflow, underfill, and inspection steps, ensuring process stability and yield from prototype through production Develop and improve tooling, fixtures, jigs, and build aids to support consistent, high-quality assembly Establish build readiness criteria and lead structured handover from engineering into manufacturing Support NPI builds and pilot production, capturing lessons learned and feeding improvements back into design and process definition • Production Support & Ramp • Support production ramp planning and readiness reviews, ensuring assembly capacity, tooling, documentation, and operator training are in place ahead of volume milestones Monitor production quality and yield, leading root cause analysis and corrective actions for recurring assembly and integration issues Drive continuous improvement across safety, quality, cost, throughput, and cycle time Partner with test and quality teams to ensure assembly processes support efficient bring-up, inspection, and validation at module level Maintain clear visibility of production issues and escalate or resolve blockers in a timely manner • Photonics Integration • Support manufacturing processes for alignment-critical integration steps, working closely with the optics/photonics engineering team who hold technical ownership Implement and maintain cleanliness, handling, and ESD controls relevant to opto-electronic assembly Contribute to in-line verification approaches and integration sequencing for optical sub-assemblies Flag manufacturability risks in photonics-related designs early and feed practical assembly constraints back to the engineering team • Contract Manufacturer & External Partner Management • Act as the primary manufacturing engineering interface with contract manufacturers and external assembly partners Define and communicate build standards, quality expectations, and process controls to CMs; audit and monitor compliance on an ongoing basis Manage component and sub-assembly readiness with supply chain and CM partners to support build schedules Lead technical reviews and engineering queries with CMs, ensuring alignment on process changes, non-conformances, and corrective actions Evaluate CM capability gaps and work with operations leadership to address them through training, process improvement, or sourcing decisions • Cross-Functional Collaboration • Work closely with mechanical, electrical, optics/photonics, test, and systems engineers throughout the product development cycle to ensure designs are assembly-ready Provide manufacturing input early in design reviews to reduce downstream risk and avoid late-stage redesign Collaborate with supply chain on component readiness, lead times, and manufacturability constraints Represent manufacturing operations in cross-functional programme reviews and escalation forums
