Objective
This senior technical position within Henry Schein engineering is based on-site at the Lompoc, California manufacturing site and serves as the principal technical authority for mechanical and electro-mechanical engineering at the site. The role requires daily on-site presence (5 days per week) on the production floor and in the assembly area; it is not eligible for remote or hybrid working arrangements. As a senior individual contributor — without direct people-management responsibility — the Principal Engineer provides deep technical leadership across day-to-day site operations, new product introduction (NPI), structured problem solving, technical file authorship, machine maintenance and automation, and continuous improvement. The role operates in a highly regulated medical device environment governed by 21 CFR 820, ISO 13485:2016, and EU MDR 2017/745. Core areas include providing technical ownership of the electro-mechanical assembly area; leading complex problem solving and CAPA investigations; driving operational efficiency through structured Lean and Six Sigma programs; supporting machine maintenance, calibration, and industrial automation; and authoring and maintaining technical files in line with EU MDR 2017/745 Annex II. The Principal Engineer mentors and develops less-senior engineers and influences technical direction through expertise and engineering judgment rather than line management.
This is an exciting opportunity to join the Engineering team in Henry Schein at the Lompoc site as the company continues to expand its manufacturing capabilities across business units geographically located throughout North America and Europe.
Essential Duties and Responsibilities include the following. Other duties may be assigned.
-
Serve as the senior technical authority for mechanical and electro-mechanical engineering at the site, setting technical direction, design rules, and engineering best practices.
-
Provide technical ownership of the electro-mechanical assembly area and supports mixing processes — including process design, line layout, line balancing, work instructions, fixture/jig/tooling design, and ongoing process performance — in compliance with 21 CFR 820.70 (Production and process controls) and ISO 13485:2016 §7.5.1.
-
Support day-to-day site activities by providing rapid, hands-on engineering response to complex production, quality, and supply issues across mechanical and electro-mechanical product lines.
Problem Solving & CAPA Leadership:
-
Lead complex, multi-disciplinary technical investigations across the Lompoc site — from rapid floor-level triage of an assembly issue through full root-cause analysis of recurring or systemic failures.
-
Apply and coach others in structured problem-solving methodologies appropriate to issue complexity: 8D, A3, DMAIC (Define / Measure / Analyse / Improve / Control), 5 Whys, Ishikawa (fishbone), Fault Tree Analysis (FTA), and Process / Design FMEA.
-
Drive nonconformance handling and CAPA investigations per 21 CFR 820.90 (Nonconforming product), 21 CFR 820.100 (CAPA), ISO 13485:2016 §8.3 (Control of nonconforming product), and ISO 13485:2016 §8.5.2 (Corrective action) — including proper distinction between containment, correction, corrective action, and preventive action.
-
Apply statistical methods to characterise process and product issues — including SPC trend analysis, capability studies (Cp, Cpk, Pp, Ppk), measurement system analysis (GR&R per AIAG MSA), hypothesis testing, and regression — to ensure conclusions are data-driven rather than anecdotal.
-
Perform and document risk impact assessment on proposed problem-solving actions per ISO 14971:2019 §5 (Risk analysis) and §7 (Risk control) before implementation; ensure benefit-risk justification per ISO 14971:2019 §8 where residual risk increases.
-
Define, execute, and document effectiveness verification (EV) for corrective actions per 21 CFR 820.100(a)(4) and ISO 13485:2016 §8.5.2(f), with quantitative acceptance criteria established up-front.
-
Lead cross-functional 'rapid response' / containment teams when escalated issues threaten line output, on-time delivery to customers, or product quality; ensure escalation to Quality and Regulatory Affairs where reportability under 21 CFR 803 (MDR) or EU MDR 2017/745 Article 87 (vigilance) may apply.
-
Author clear, defensible investigation reports suitable for FDA inspection, Notified Body audit, and internal QMS review; mentor other engineers in technical-writing standards for investigations.
-
Build problem-solving capability across the site engineering and technician population through hands-on coaching, structured kaizen events, and standardised templates.
-
Author and maintain technical files and Design History File content for site-manufactured product in line with EU MDR 2017/745 Annex II (Technical Documentation) and 21 CFR 820.30(j) (DHF), partnering with Quality and Regulatory Affairs as engineering technical owner.
-
Provide subject-matter expertise on machine maintenance, calibration, and industrial automation — covering PLC, servo, pneumatic, sensor, and vision systems — including reliability engineering, preventive maintenance strategy, and equipment requalification per ISO 13485:2016 §6.3 (Infrastructure) and §7.5.1(c).
Operational Efficiency & Continuous Improvement:
-
Own the engineering contribution to the site's operational efficiency agenda — translating Plant strategic objectives into a prioritised, data-driven pipeline of efficiency projects with quantified business cases (yield, throughput, labour, scrap, energy, COPQ).
-
Drive Overall Equipment Effectiveness (OEE) improvement on electro-mechanical assembly lines by analysing the three OEE components (Availability, Performance, Quality) and targeting the loss categories with greatest financial impact.
-
Lead value stream mapping (VSM) of end-to-end manufacturing flows; identify and remove non-value-add activities, queues, and rework loops.
-
Apply Lean tools rigorously and coach others in their use: standard work, 5S, SMED (single-minute exchange of die / changeover reduction), kanban, line balancing (takt-based), kaizen events, A3 thinking, and visual management.
-
Apply Six Sigma DMAIC methodology to chronic process variation; deploy Statistical Process Control (SPC) on critical-to-quality (CTQ) parameters with appropriate control limits, Western Electric rules, and reaction plans.
-
Use Theory of Constraints (TOC) thinking to identify and elevate the system bottleneck; sequence improvement work so capacity gains are realised rather than absorbed upstream.
-
Drive First Pass Yield (FPY) and rolled throughput yield (RTY) improvement; design and implement poka-yoke (error-proofing) into assembly fixtures, work instructions, and test stations.
-
Lead targeted scrap and rework reduction campaigns; quantify and track Cost of Poor Quality (COPQ) including internal failure, external failure, appraisal, and prevention costs.
-
Drive cycle-time and changeover-time reduction on electro-mechanical assembly lines through workstation re-design, fixture improvements, and automation insertion.
-
Improve labour productivity through line re-balancing, work-content analysis, and targeted automation of low-skill / high-volume tasks (cobots, pick-and-place, automated test).
-
Improve maintenance efficiency through reliability-centred maintenance (RCM), MTBF/MTTR tracking, condition-based monitoring, and spare-parts strategy.
-
Identify and deliver utility and energy efficiency improvements (compressed air, HVAC, lighting, process heating) where these contribute meaningfully to site COGS or sustainability objectives.
-
Apply risk-based qualification thinking to validation work to avoid over-validating low-risk changes — using ISO 14971:2019 risk output to scope IQ/OQ/PQ effort proportionately and reduce time-to-implementation while remaining compliant with 21 CFR 820.75 and ISO 13485:2016 §7.5.6.
