Job Description
This position is in our organization’s Device Development & Technology (DD&T) group in our Research division. Our organization’s DD&T group is responsible for the development of devices, combination products, processes, testing and assembly equipment from conception through product launch. Products include autoinjectors, inhalers, implants, infusion pumps, vaginal rings and connected devices/apps. The person in this position contributes to high impact, complex, cross-functional, and cross-divisional teams, initiatives and will provide input to achieve project goals. Effective collaboration with teams is essential to meet our company s goals/objectives. The group also plays a key role in supporting commercially launched products.
The DD&T organization is seeking an accomplished technical leader for the role of Associate Principal Engineer (R4) . In this high-impact position, you will direct cross-functional engineering teams in the execution and delivery of complex combination product development programs.
While a deep foundational grounding in mechanical engineering, drug delivery systems, and manufacturing principles is required to provide rigorous technical scrutiny, the primary focus of this role is technical leadership, cross-functional team orchestration, and program delivery .
You will lead internal engineering teams (mechanical, systems, human factors, packaging, materials) and direct external partners (device OEMs, tooling/molding vendors, and CDMOs). You will represent the device constituent part at the integrated Development team, ensuring program milestones, design verification, manufacturing readiness, and regulatory compliance are achieved seamlessly.
Key Responsibilities:
1. Device Sub-Team Leadership & CMC Integration
Chair and Lead Device Development Sub-Teams (DST): Establish technical roadmaps, integrated schedules, and resource allocation across internal technical specialists and external development partners.
Act as the single-point device design accountable leader on working group levels, ensuring device milestones are tightly coupled with clinical supply timelines, formulation characteristics, filling operations, and regulatory submission targets.
Lead formal technical stage-gate reviews (Concept Selection, Design Freeze, Design Verification Readiness, and Design Transfer Approval), driving consensus and resolving complex technical trade-offs between form, fit, function, manufacturability, cost, and schedule.
2. Design Controls, Risk Management & Technical Oversight
Own the strategy, compilation, and maintenance of complete, audit-ready DHFs in full alignment with 21 CFR Part 4, 21 CFR 820.30, and ISO 13485.
Oversee the technical architecture of DV&V programs, ensuring test methods, sample sizes, statistically based acceptance criteria, and Gauge R&R validations satisfy global regulatory expectations.
Lead team through product-level risk analyses per ISO 14971, facilitating cross-functional Hazard Analyses, Design FMEAs, and Process FMEAs to ensure robust, patient-centric device functionality.
Review and approve detailed engineering specifications, component drawings, holding internal and external contributors to first-principles engineering rigor.
3. Supplier, OEM & Commercial Assembly Line Readiness
Manage day-to-day technical deliverables from device OEMs, and primary container suppliers.
Interrogate device supplier and component manufacturing processes against combination product process specifications, Critical Quality Attributes (CQAs), and Critical to Function (CTF) dimensions.
Collaborate with internal and external stakeholders to build a comprehensive control strategy.
4. Regulatory Strategy & Health Authority Submissions
Author, review, and defend the device constituent sections of global regulatory filings (e.g., IND, IMPD, BLA Module 3.2.P.7, NDA, MAA).
Formulate technical responses to information requests (IRs) and deficiency letters from health authorities (FDA, EMA, PMDA) and serve as the primary device subject matter expert (SME) during Pre-Approval Inspections (PAIs) and notified body audits.
5. Talent Mentorship & Capability Building
Mentor, guide, and develop early-to-mid career engineers (R1–R3), fostering an organizational culture rooted in technical excellence, disciplined root-cause problem solving, and cross-functional leadership.
Champion continuous improvement initiatives across DD&T, standardizing design control templates, sub-team governance frameworks, and technical best practices.
Education Minimum Requirements:
Bachelor of Science (BS) in Mechanical Engineering, Biomedical Engineering, Chemical Engineering, Materials Science, or related engineering discipline with 8 years of progressive regulated industry experience in medical device or combination product development; OR
Master of Science (MS) in a relevant engineering discipline with 6 years of relevant experience; OR
Ph.D. in a relevant engineering discipline with 4 years of relevant experience.
Required Experience and Skills:
Demonstrated Technical Team Leadership : Proven experience leading cross-functional engineering teams or sub-teams in a matrixed pharmaceutical, biotechnology, or medical device development environment.
Combination Product Design Controls : Comprehensive mastery of combination product regulations and design control standards, including 21 CFR Part 4, 21 CFR 820.30, ISO 13485, and ISO 14971.
Program Delivery & Stakeholder Communication : Exceptional track record of managing complex technical milestones, balancing interdisciplinary priorities, and translating technical risks into clear, executive-level summaries for senior leadership and partner groups.
Technical Evaluation & Critical Review : Strong mechanical aptitude, statistical analysis and first-principles engineering depth (tolerance stack analysis, material compatibility, and mechanical testing) to critically review, approve, and challenge technical work packages.
Risk Management Expertise : Proven expertise facilitating and authoring system/device DFMEAs, PFMEAs, and risk-benefit analyses.
Preferred Experience and Skills:
Prior direct experience serving as the dedicated Device Technical Lead (DTL) / Device Sub-Team Lead on combination product programs.
Direct experience authoring and defending device constituent sections of BLA, NDA or IND submissions, as well as addressing formal Health Authority Information Requests.
Hands-on experience directing external device OEMs, custom equipment automation integrators, and secondary packaging/assembly CDMOs.
Extensive experience in bench-top device functional testing and data analysis and designing and facilitating in clinic device usability studies.
Experienced in development and/or characterization of autoinjectors, PFS, on-body and/or near body injection systems.
