**We are searching for the best talent for a **Principal R&D Validation Engineer based in Irvine, CA.
**Purpose: **The Principal R&D Validation Engineer leads the technical strategy and execution for advanced consumable product qualifications specializing in injection molded components, driving high-impact product and process development from concept through transfer to manufacturing. This role combines deep hands‑on technical leadership, cross‑functional program leadership, and strategic vision to solve complex customer and patient needs. The Principal R&D Engineer is responsible for setting engineering direction, ensuring robust design and verification practices, managing technical risks, and mentoring more junior engineers. Works with minimal oversight and routinely influences senior leaders and external partners.
You will be responsible for:
Own the technical qualification roadmap and architecture for major consumable products or portfolios; define technical strategy, key milestones, and success metrics.
Lead complex, multi‑discipline development programs from concept through, design for moldability/manufacturability, supplier engagement, design verification, validation, and transfer to manufacturing; manage technical tradeoffs and priorities.
Provide advanced mechanical and system design leadership: define product architectures, systems interactions, requirements decomposition, and high‑level design reviews.
Lead root-cause and corrective actions
Drive adoption of advanced engineering methods (e.g., simulation, multi‑physics modeling, DOE, advanced prototyping, tolerance analyses) to accelerate development and de‑risk designs.
Lead and approve design control artifacts, risk management activities (e.g. dFMEA, pFMEA) verification/validation plans, and release decisions in accordance with regulatory and quality requirements.
Collaborate closely with R&D, Quality, Regulatory Affairs, Manufacturing, Supply Chain, and Commercial to align on manufacturability, scalability, cost of goods, and launch readiness.
Mentor and develop engineering staff: provide technical coaching, run design reviews, and cultivate engineering best practices across the team.
Represent R&D engineering in senior‑level program and governance meetings, providing clear, data‑driven recommendations and status to stakeholders.
Manage external technical partnerships and suppliers: set technical requirements, qualify vendors, and oversee supplier development when needed.
