Job Overview
DePuy Synthes is recruiting for a Principal Optimization Engineer. The role is available across multiple countries and may be posted under different requisition numbers to comply with local requirements. You may apply to any or all of the postings; applications will be considered as a single submission.
Location: Raynham, Massachusetts, United States, Loughbeg, Ringaskiddy, Ireland
Raynham, MA, US – Requisition Number: R-071956
Loughbeg, Ringaskiddy, Ireland – Requisition Number: R-073814
Key Responsibilities
Define and own the operations research strategy and solution roadmap — spanning optimization, simulation, and digital twin — to address unmet supply chain needs aligned with DePuy Synthes strategic objectives. Lead the full solution lifecycle: frame the problem, develop and validate models, pilot with business partners, then scale and deploy solutions that drive measurable improvements in supply chain experience, effectiveness, and efficiency.
Partner with supply chain business leaders across DePuy Synthes functions — including manufacturing, quality, procurement, planning, logistics, and customer experience — to identify, prioritize, and frame complex problems amenable to analytical solutions. Effectively manage communication of execution timelines and performance with customers, senior leaders, and other key stakeholders.
Craft novel algorithms, heuristics, and modeling frameworks to solve high‑complexity supply chain problems — including end‑to‑end optimization, multi‑echelon inventory optimization (MEIO), network modeling, simulation, and digital twin — and own deliverables end to end.
Conduct strategic build vs. buy analysis — lead detailed financial, operational, and technical analysis to evaluate in‑house vs. external development, assessing strategic implications of sourcing decisions.
Incorporate AI/ML techniques — including machine learning, Generative AI, and Agentic AI — where they strengthen or complement core operations research solutions, enabling more adaptive and intelligent decision‑support capabilities.
Develop and monitor success metrics tied to adoption, operational impact, and realized savings — ensuring solutions deliver quantifiable business value and continue to perform at scale.
Collaborate with data scientists, data engineers, full‑stack developers, and product management teams to produce sustainable, reusable solutions backed by comprehensive documentation and user training, reducing technical debt and enabling broad organizational adoption.
Drive innovation of next‑generation supply chain methods, staying at the forefront of the operations research literature and translating emerging techniques into practical, deployable solutions.
Qualifications
Education:
Master’s or Ph.D. (preferred) in Operations Research, Industrial Engineering, Applied Mathematics, or a related technical discipline is strongly preferred.
Required Experience and Skills
6+ years of progressive work experience in operations research, supply chain modeling, or advanced analytics — with a track record of designing, developing, and deploying optimization and simulation solutions in complex operational environments.
Experience incubating and productionalizing new analytical capabilities, working closely with data engineers, data scientists, and technical teams from idea generation through implementation.
Deep expertise in mathematical modeling, algorithm design, and heuristic development for large‑scale supply chain problems including network optimization, inventory optimization, and scheduling.
Significant hands‑on experience with optimization engines such as CPLEX, Gurobi, FICO Xpress, and Lyric.
Hands‑on experience with discrete‑event and continuous simulation platforms such as Simio, FlexSim, AnyLogic, SimPy, or Arena; familiarity with additional simulation environments is a plus.
Proficiency in one or more programming languages — Python, R, Julia, or equivalent — is required; experience building production‑grade analytical solutions is a strong plus.
Strong working knowledge of AI/ML techniques — including machine learning, deep learning, Generative AI, and Agentic AI — and the ability to integrate these methods into operations research solutions where appropriate.
Strong knowledge of data science, statistical modeling, and visualization tools including decision trees, neural networks, clustering, regression, and data mining techniques.
Demonstrated expertise in supply chain modeling across planning, procurement, manufacturing, logistics, and customer fulfillment including deep understanding of supply chain fundamentals — inventory theory, BOM structures, lead times, demand planning.
Experience engaging with and managing university and research institution partnerships, including co‑developing methodologies and translating academic research into applied solutions, is a plus.
Demonstrated success in creative problem solving with proven ability to work cross‑functionally, build partnerships, and influence change across a large, complex organization.
Strong business acumen — able to assess the most appropriate analytical approach given business requirements, constraints, and trade‑offs.
Demonstrated ability to develop business cases and track business benefits, including ROI, P&L savings, cash flow impact, and other key financial metrics.
Self‑starter with a hands‑on approach to fast prototyping and a bias toward action in ambiguous, fast‑moving environments.
Proven ability to manage and prioritize multiple competing projects and stakeholder demands in a deadline‑driven environment.
Excellent written and verbal communication skills — including model documentation and analyses and demonstrated experience presenting to and influencing senior leaders.
Preferred
Familiarity with supply chain domains within MedTech or similar industry.
Familiarity with tools like Jira and Confluence.
Experience at the OR/ML interface or experience applying ML/GenAI methods to enhance and improve optimization algorithms.
UX/UI design experience or familiarity partnering with UX/UI designers.
Familiarity with design tools such as Figma and Adobe XD.
Other
Language: English proficiency required.
Travel: Up to 15% domestic travel.
Lean Six Sigma Black Belt or equivalent preferred.
APICS certification (CPIM, CSCP) is a strong plus.
