Senior Chemical Process Engineer

Senior Chemical Process Engineer

Imagine engineering the sophisticated fluid, gas, and chemical delivery systems that form the lifeblood of the world's most advanced semiconductor fabrication facilities. At SSOE you will continuously expand your expertise by confronting diverse and complex process engineering challenges unique to the semiconductor and advanced high-tech industrial sectors. From designing ultra-pure water (UPW) systems that deliver water cleaner than any found in nature, to engineering specialty gas and chemical distribution networks with exacting purity and safety requirements, to developing robust hazardous wastewater treatment solutions, your work will be at the intersection of precision, safety, and innovation. You'll be supported by access to advanced training, leading design and analysis tools including hydraulic modeling and pipe stress software, and a collaborative multidisciplinary culture. We foster your ambition with clear pathways for career progression, whether your aspiration is technical leadership, project management, or becoming a revered subject matter expert in high-purity process systems. All of this unfolds within a truly integrated team environment that champions knowledge sharing, innovation, and technical excellence, backed by the stability and proven delivery of a well-established firm.

We are seeking a Senior Chemical Process Engineer to join our integrated design-build team, supporting the delivery of advanced technology, semiconductor, cleanroom, and mission-critical facilities. This role is well-suited for an engineer who has developed a solid foundation in process system design and is ready to take on greater responsibility in complex, high-performance environments. In this position, you will contribute to the design and execution of critical process systems that support cutting-edge manufacturing and operational performance. You will work closely with senior engineers and multidisciplinary teams to develop practical, efficient, and reliable engineering solutions while continuing to grow your technical expertise.

At SSOE, we don't just talk about the future, we build it. As a leader in industry AI adoption, we empower our team to work smarter by providing responsible access to the industry leading AI Large Language Models, vibe-coding platforms, and securely integrating advanced tools into every role. From day one, you'll receive the training and support needed to leverage AI as a core tool for enhancing productivity, sparking creativity, and streamlining complex workflows.
