What is a chemical process engineer?

A chemical process engineer’s responsibilities cover designing and developing processes for transforming raw materials into marketable products. You can hold a chemical process engineer job in an industry that processes natural gases, paper, pharmaceuticals, plastic, food, and other products. You will analyze procedures, communicate effectively with team members, apply math, science, and engineering concepts, and conduct experiments and report the results. Many types of chemical engineering careers exist in chemical production and manufacturing, mineral processing, oil exploration, sustainable engineering, and alternative energy fields. However, you can find chemical engineers with diverse duties in jobs in nearly every industry that creates a product.

What does a chemical process engineer do?

A Chemical Process Engineer is responsible for designing, developing, and optimizing processes used in the production of chemicals, fuels, pharmaceuticals, food, and other products. They work to improve efficiency, safety, and sustainability in manufacturing plants by analyzing chemical reactions, equipment, and workflows. Chemical Process Engineers often collaborate with other engineers and technicians to troubleshoot problems and implement new technologies in production systems.

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

To thrive as a Chemical Process Engineer, you need a solid background in chemical engineering principles, process design, and safety regulations, typically supported by a bachelor's degree in chemical engineering or a related field. Familiarity with process simulation software (such as Aspen Plus or HYSYS), knowledge of P&ID development, and relevant certifications like Six Sigma are highly valuable. Strong analytical thinking, problem-solving skills, and effective teamwork and communication abilities help you excel in this role. These skills ensure that processes are efficient, safe, and cost-effective, supporting both operational excellence and regulatory compliance.

What are some typical challenges a chemical process engineer faces when optimizing plant operations?

Chemical Process Engineers often encounter challenges such as balancing production efficiency with safety and environmental regulations, troubleshooting unexpected equipment malfunctions, and integrating new technologies into existing systems. They must collaborate closely with multidisciplinary teams, including operators, maintenance staff, and quality control, to implement process improvements. Staying adaptable and proactive in problem-solving is key to overcoming these challenges while maintaining smooth and cost-effective operations.

What is the difference between Chemical Process Engineer vs Chemical Production Technician?

AspectChemical Process EngineerChemical Production Technician
CredentialsBachelor's degree in chemical engineering or related fieldAssociate's degree or technical certification in chemical technology
Work EnvironmentDesign, optimize, and oversee chemical processes in labs or plantsOperate and maintain equipment on the production floor
Employer & Industry UsageManufacturing, petrochemical, pharmaceuticals, and energy sectorsChemical manufacturing plants and processing facilities

The Chemical Process Engineer focuses on designing and improving chemical processes, requiring a degree in engineering. In contrast, the Chemical Production Technician handles daily operations and equipment maintenance, often with technical certifications. Both roles are vital in chemical industries but differ in responsibilities, education, and work scope.

Job description

AT Process Technologies (ATP) is a pioneering manufacturing company focused on the development and deployment of modular energetics production plants. Using breakthrough chemistry and automation that operates continuously and generates little to no waste, ATP is expanding energetics production to meet the munitions demands of the US and Allies safely, rapidly, and cost effectively.

Summary

ATP is building a core team of engineers to work alongside our Process and Chemistry R&D teams to develop an autonomous skidded system for next-generation energetics manufacturing. In this role you will own and deliver a subsystem from concept through commissioning. The ideal candidate has previously owned a critical project end-to-end (design, build, and execution) and brings the engineering fundamentals to solve a wide range of problems quickly and rigorously.

Key Responsibilities

  • Own the mechanical design and development of subsystem-level hardware from concept through pilot testing and production

  • Design and fabricate reactors and other continuous process systems.

  • Work alongside a team of mechanical and process engineers to design, build, test, and commission hardware

  • Collaborate with automation and controls engineers on integrated system development

  • Lead hands-on testing, hardware iteration, and rapid prototyping based on performance feedback

  • Drive manufacturability, part selection, and tolerance stack-up decisions for scalable production

  • Conduct engineering analysis including stress, thermal, and fluid modeling; perform DFM and DFMEA

  • Evaluate vendors, lead design reviews, and validate compliance and performance

  • Contribute to test plans, technical documentation, and engineering reviews

Required Qualifications

  • Bachelor's degree in Mechanical Engineering, Chemical Engineering, Robotics, Mechatronics, or a related discipline

  • 5+ years of professional experience in hardware design and development

  • Strong proficiency in 3D modeling and CAD tools (Siemens NX, Fusion 360, or equivalent)

  • Demonstrated application of mechanical fundamentals - structural, thermal, and materials - to deliver robust, well-engineered designs

  • Demonstrated experience owning hands-on, end-to-end hardware development efforts (industry projects, FSAE, Design-Build-Fly, rocketry teams, or similar)

Preferred Qualifications

  • 5-10 years of relevant industry experience

  • Background in robotics, PLCs, mechatronics, or process development

  • Experience with continuous processes and manufacturing

  • Familiarity with at least one programming language (Python, C++, or similar)

  • Experience designing hardware for reactive, hazardous, or energetic chemistries

Additional Requirements

  • Ability to lift 50 lbs

  • U.S. Person and ability to obtain a security clearance

  • Ability to work on-site and travel as needed
