Job Description:

Engineer II, Materials Quality Engineering

We are seeking a motivated Engineer II to join our Materials Quality Engineering (Supplier Quality) team supporting our specialty gases supplier base and U.S. manufacturing operations. In this role, the engineer will support the assessment and management of supplier risk, capability, and quality performance for specialty and electronic gases, including toxic, corrosive, and ultra‑high‑purity materials used in semiconductor and advanced technology manufacturing.

This position supports the Materials Solutions Division and the manufacturing plant in Danbury, CT, while working closely with regional and global partners across Materials Quality, Operations, R&D, Procurement, and Customer Quality. The Engineer II operates with moderate autonomy, applying sound engineering fundamentals, following established quality systems, and developing deeper technical judgment through hands‑on supplier engagement and issue resolution.

In this role you will:

* Support supplier quality activities for specialty gases, including performance monitoring, corrective actions, and audits.

* Execute supplier issue resolution activities under defined quality systems and escalation paths.

* Support material qualification, supplier change management (MOC), and risk assessment activities for specialty gases.

* Analyze gas‑related quality issues and participate in root cause investigations using structured problem‑solving tools (8D, 5‑Why, fishbone).

* Escalate emerging risks appropriately while developing independent risk‑assessment capability.

Technical - Specialty Gas & Materials Quality Responsibilities

* Develop working knowledge of specialty gas chemistry, purity requirements, and safety considerations.

* Review eCOA data, analytical results, and SPC trends to identify potential quality concerns.

* Actively identify continuous improvement opportunities and take ownership for defining project objectives, success criteria, and implementation actions related to specialty gas quality and supplier performance.

* Support investigations related but not limited to moisture, contaminants, and variability, with guidance from senior team members when needed.

* Build understanding of cylinder, valve, liner, and delivery system fundamentals and their impact on gas quality.

* Participate in supplier process reviews, audits, and improvement activities.

* Apply SPC, control plans, PFMEA, and structured problem‑solving methods within assigned scope.

* Accurately analyze and summarize technical data to support decision‑making and escalation.

Cross-Functional Leadership:

* Partner with Business Units, Procurement, R&D, and Operations to ensure continuity of supply for materials and fabricated components.

* Monitor key supplier metrics and provide visibility and escalation to cross-functional teams when needed.

* Participate in Business Continuity Planning (BCP) and risk mitigation strategies for assigned suppliers.

* Provide support for urgent quality or supply issues as needed

Qualifications / Traits:

* Bachelor's degree in Chemical Engineering, Materials Science, Chemistry, Mechanical Engineering, or related discipline.

* 2-5 years of experience in supplier quality, materials quality, chemicals, specialty gases, or high‑purity manufacturing environments.

* Familiarity with quality systems, SPC, basic statistical tools, audits, and corrective action processes.

* Exposure to gas analysis concepts (e.g., moisture control, impurity tracking) is a plus.

* Working knowledge of statistical or quality tools (e.g., Minitab, JMP, Camline).

* Strong analytical skills, attention to detail, and ability to learn complex technical material.

* Effective communication skills and ability to collaborate across functions.

* Ability to work independently on defined tasks and seek guidance when appropriate.

* Ability to travel up to 10% domestically or internationally
