What is a senior chemical process engineer?

Senior Chemical Process Engineers are experienced professionals who design, develop, and optimize chemical processes used in manufacturing. They lead projects, oversee process safety and efficiency, and mentor junior engineers. Their work ensures that industrial chemical operations are cost-effective, environmentally friendly, and comply with regulations. Senior Chemical Process Engineers often collaborate with multidisciplinary teams and play a key role in troubleshooting and continuous improvement initiatives.

How do senior chemical process engineers typically collaborate with cross-functional teams during large-scale projects?

Senior Chemical Process Engineers frequently work alongside professionals from disciplines like mechanical engineering, instrumentation, safety, and project management. They play a key role in translating process requirements into actionable engineering solutions and ensure process integration aligns with overall project goals. Regular meetings, detailed documentation, and clear communication are essential, as these engineers often lead technical discussions, resolve interdisciplinary challenges, and coordinate between design, operations, and quality assurance teams to drive projects forward efficiently.

What are the key skills and qualifications needed to thrive as a senior chemical process engineer, and why are they important?

To thrive as a Senior Chemical Process Engineer, you need a strong background in chemical engineering principles, process design, and problem-solving, typically supported by a bachelor's or master's degree in chemical engineering. Familiarity with process simulation software (such as Aspen Plus or HYSYS), plant safety standards, and relevant certifications (like Professional Engineer licensure) is highly valuable. Strong analytical thinking, leadership, and effective communication skills help drive project success and lead cross-functional teams. These skills and qualities are crucial for optimizing manufacturing processes, ensuring safety, and delivering cost-effective solutions in complex industrial environments.

What is the difference between Senior Chemical Process Engineer vs Chemical Process Engineer?

AspectSenior Chemical Process EngineerChemical Process Engineer
Required CredentialsBachelor's or Master's in Chemical Engineering; 5+ years experienceBachelor's in Chemical Engineering; entry to 2 years experience
Work EnvironmentDesign, optimization, and supervision in manufacturing or R&D facilitiesAssist in process design, testing, and operation in manufacturing plants
Employer & Industry UsageManufacturing, oil & gas, pharmaceuticals, chemicalsSimilar industries, often as entry-level or mid-level roles

The main difference between a Senior Chemical Process Engineer and a Chemical Process Engineer lies in experience, responsibilities, and seniority. Senior engineers typically lead projects, oversee teams, and have more advanced expertise, while chemical process engineers focus on supporting process design and operation. Both roles are essential in chemical manufacturing and related industries, but senior positions require more experience and leadership responsibilities.

Job description

Overview

The High Frequency Technology Center (HFTC) is seeking an R&D Process Engineer to develop, maintain and optimize manufacturing processes to fabricate passive interposer substrates for Keysight’s Heterogeneous Integration technology. This position is onsite at Keysight Headquarters in Santa Rosa, CA. Live in beautiful Sonoma County amongst vineyards, redwood forests, rivers, lakes and coastline while working on state-of-the-art advanced packaging technologies.

The Process Engineer will own process development and process control to meet quality and production metrics. Responsibilities include a combination of R&D and manufacturing in partnership with Design, Integration, Test, Operations, Maintenance, Product and Failure Analysis teams. The Process Engineer is accountable for yield, cycle time, throughput, and quality of their process. This role involves technical depth in semiconductor processing, strong hands-on aptitude, as well as effective communication and teamwork to meet department-level objectives.


Responsibilities

Process Development Engineers at HFTC are responsible for process development and sustaining of custom, cutting-edge, micro and nano-fabrication technologies.

The focus of this position is process development, manufacturing sustainability, and R&D support for new product introductions, with specialization in wafer fab processes.

Responsibilities include but are not limited to:
• Deep knowledge and expertise in wafer process development in one or more of the following areas, listed in order of preference: PECVD/CVD strongly preferred, followed by dry etch, PVD/sputtering, ashing, or similar vacuum-based processes.
• Own and advance plasma process performance across PECVD/CVD, dry etch, PVD/sputtering, and ashing tools by driving film quality, profiles, uniformity, selectivity, chamber health, defect reduction, and overall process robustness through structured DOEs
• Collaborate with equipment engineering on tool performance optimization, preventive maintenance strategies, throughput enhancements, and new tool installs or upgrades
• Drive process control and stability through SPC charting, daily reviews, root cause analysis, and corrective actions using statistical tools (e.g., JMP)
• Working closely with other process, integration, product, and circuit design engineers to define process and performance targets
• Defining process flows, develop new processes and drive continuous process improvement (CPI) efforts to maximize product yield
• Report process metrics, root cause investigations, and process change implementations at the department level
• Ensuring successful process hand off to manufacturing partners
• Working with Operations to implement robust process control and support production processes; diagnose and resolve process problems with urgency
• Leading capital equipment acquisition projects that include tool evaluation, characterization, process development, and qualification
• Broader experience in upstream and downstream processes and the ability to understand process interactions


Qualifications
