Clorox is the place that's committed to growth - for our people and our brands. Guided by our purpose and values, and with people at the center of everything we do, we believe every one of us can make a positive impact on consumers, communities, and teammates. Join our team. #CloroxIsThePlace

Your role at Clorox:

The Principal Process Engineer supports manufacturing operations and capital projects by applying deep expertise in process engineering, product quality systems, micro & cleanability, and sanitary design (CIP/SIP). The role serves as the subject matter expert for sanitary and non sanitary equipment, piping layout, facility design, and materials of construction, ensuring all systems meet CIP/SIP and operational requirements.
This position provides influential technical leadership across multiple teams, driving change management, process optimization, problem solving, root cause analysis, and adherence to Clorox engineering and regulatory standards. Responsibilities include supporting innovation, new production start-ups, and improvements to existing operations.

In this role, you will:

  • Lead process design, development and documentation of hygienic process systems, materials selection, and CIP/SIP cleanability, ensuring all designs meet Clorox Engineering Standards.
  • Provide technical leadership in sanitary design, water/wastewater systems, facility operations, and process layouts; select materials of construction and cleanability finishes based on required parameters.
  • Remove execution barriers and resolve complex manufacturing challenges by applying advanced process engineering principles and integrating emerging technologies to optimize system efficiency, operational reliability, safety performance, product quality, and regulatory compliance.
  • Lead or support plant optimization, cross-functional projects, and new product initiatives across multiple sites.
  • Serve as SME for processes and materials of construction for new builds, renovations, and problem-solving. Manage projects using Clorox capital processes (scope, RCA, decks, schedules, prioritization, risk).

What we look for:

  • Bachelor's Degree in related field.
  • 8+ years of process engineering experience, delivering end-to-end capital projects in sanitary or aseptic manufacturing. Food & beverage, dairy, biotech/pharma, nutraceuticals, or cosmetics preferred.
  • Expertise in sanitary/hygienic design, facility and equipment layouts, and utilities.
  • Excellent communication skills (written and verbal) to include the ability to communicate technical information effectively to non-technical audiences.
  • Strong technical and project leadership; proactive, self-directed, and willing to drive process rigor and lead change.
  • Must be willing and able to travel to various manufacturing plants, 25 - 50%, domestic and international.

Workplace type:

Hybrid: This individual will work at least 3 days in the office.

Our values-based culture connects to our purpose and empowers people to be their best, professionally and personally. We serve a diverse consumer base which is why we believe teams that reflect our consumers bring fresh perspectives, drive innovation, and help us stay attuned to the world around us. That's why we foster an inclusive culture where every person can feel respected, valued, and fully able to participate, and ultimately able to thrive. Learn more.
