As a senior technical authority, you will lead internal and collaborative R&D programs and interface with global industry and academic partners to deliver packaging solutions for heterogeneous integration, targeting applications in AI, HPC, power electronics, RF, and photonics. You will provide design expertise on the project, analysis, assembly and technical guidance on test and validation activities and will be expected to participate in these activities in the labs at Catapult’s Innovation Centre.
This position drives all packaging aspects of prototype/ product development by charting and enabling packaging technology roadmaps in collaboration with internal and external stakeholders.
Key tasks include:
* Architect and deliver cutting-edge packaging solutions for heterogeneous integration
* Serve as a solution architect for 3D and 2.5D packaging platforms, resolving system-level packaging challenges from concept design through to prototype and demonstrator builds
* Lead the definition, design, and development of advanced packaging solutions incorporating substrates, interposers, chiplets, high‑density interconnects, microbump /UCIe interfaces, TSVs, and hybrid bonding for various applications including automotive, telecom and photonics
* As a solution architect, resolve complex semiconductor packaging challenges starting from customer requirement analysis to package design, assembly and validation
* Support the planning and development of technical strategies and roadmap in line with the Catapult’s themes and technological interests
* Lead multiple projects simultaneously, working closely with the Project Manager to meet system requirements and customer needs
* Lead and coordinate technical work packages, interacting with packaging design, substrate, assembly, and thermal teams
* Engage in hands‑on prototyping and lab‑level validation where needed, using CSA’s Innovation Centre capabilities
* Design and develop various advanced microelectronics modules/ systems and demonstrators using a combination of technologies
* Provide technical guidance on design, assembly, test, and validation activities with an occasional need to participate in these activities in the labs at CSA Catapult’s Innovation Centre
* Technical reporting to the project team and a wider audience to demonstrate regular progress
* Consult with the Business Development team and customers to identify collaborative opportunities
* Plan projects, estimate resources to budget, and work on bids, technical proposals, and quotations, working closely with the bid team and commercial team
* Reviewing technical risk assessments
* Work with the Head of packaging to ensure the team is working in‑line with company strategy
* Act as a strategic thinker responsible for the development of new and emerging technologies
* Represent CSA Catapult in collaborative consortia and client engagements, presenting technical strategy and innovation value
* Participate in bid preparation, resource planning, and stakeholder engagement with the business development and commercial teams
