What is a chemical engineer?

Chemical engineers are professionals who apply principles of chemistry, physics, mathematics, biology, and engineering to solve problems involving the production or use of chemicals, fuel, drugs, food, and many other products. They design processes and equipment for large-scale manufacturing, plan and test production methods, and oversee facility operations. Chemical engineers work in a variety of industries, including pharmaceuticals, energy, food processing, and environmental health and safety. Their work helps turn raw materials into useful products safely, efficiently, and sustainably.

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

To thrive as a Chemical Engineer, you need a solid background in chemistry, mathematics, and process engineering, usually supported by a bachelor's degree in chemical engineering or a related field. Familiarity with process simulation software (such as Aspen Plus or HYSYS), safety regulations, and laboratory analysis tools is commonly required. Strong problem-solving, project management, and teamwork skills help Chemical Engineers excel in collaborative and dynamic environments. These competencies are vital for designing efficient processes, ensuring safety, and driving innovation in chemical manufacturing and related industries.

What are some common challenges chemical engineers face when working on process optimization projects?

Chemical engineers often encounter challenges such as balancing safety requirements with production efficiency, troubleshooting complex process issues, and adapting to new technologies or regulations. These projects typically require close collaboration with multidisciplinary teams, including operators, quality control, and maintenance staff, to implement changes without disrupting ongoing operations. Staying up-to-date with industry best practices and maintaining strong problem-solving skills are essential to successfully navigate these challenges and drive continuous improvement.

What is the difference between Chemical Engineer vs Process Engineer?

AspectChemical EngineerProcess Engineer
CredentialsBachelor's degree in chemical engineering; often licensed as a Professional Engineer (PE)Bachelor's degree in chemical, process, or industrial engineering; may also pursue PE licensure
Work EnvironmentFactories, laboratories, research facilities, and industrial plantsManufacturing plants, process design, and optimization settings
Industry UsageChemical, pharmaceuticals, energy, and materials industriesManufacturing, refining, and process industries

Both Chemical Engineers and Process Engineers work in industrial environments and often require similar educational backgrounds. Chemical Engineers typically focus on designing and developing chemical processes, while Process Engineers optimize and improve existing manufacturing processes. Their roles often overlap, but their primary responsibilities differ slightly based on project scope and focus.

Is there a high demand for chemical engineers?

Chemical engineers are in high demand across industries such as pharmaceuticals, energy, and manufacturing due to ongoing innovation and the need for process optimization. Employment opportunities are expected to grow faster than the average for all occupations, especially for those with strong technical skills and relevant certifications.

What type of jobs do chemical engineers do?

Chemical engineers design, develop, and optimize processes for producing chemicals, fuels, pharmaceuticals, and materials. They work in industries such as manufacturing, energy, and environmental protection, often using tools like process simulation software and adhering to safety and environmental regulations.

Summary

We are seeking a chemical engineer to work on the piloting and scale-up of our energetics manufacturing . This role is at the center end of ATP's scaling plans: you will manage the critical process for detailed designs of our manufacturing facilities. Your task will be to design and execute experiments, complete engineering designs, and manage projects that de-risk scale up. This position is highly independent, hands-on, and involves hands-on pilot plant engineering work, simulation and design work, interfacing with external vendors and contractors, and managing our supply chain.

 

Key Responsibilities:

  • Design and execute critical pilot plant experiments generating reliable, actionable data for reaction and unit-operation design and scale-up.

  • Review and produce material and energy balances, block flow diagrams, P&ID drawing sets, for internal cost modeling and external equipment vendors

  • Interface with the mechanical engineering team to manage hardware design requirements for our pilot plant operations

  • Manage aspects of large-scale equipment procurement, raw material procurement, combining external negotiation with a knowledge of the technical and economic requirements

  • Lead HAZOP analyses with our process design and automation team to define safety SOPs and controls narratives

Required Qualifications

  • B.S., M.S., or PhD in Chemical Engineer, Process Engineering, Petroleum Engineering, or a similar field

  • 5+ years of professional experience in chemical engineering from pilot to production scale

  • High proficiency with chemical engineering practices: reaction engineering, simulation, material and energy balances, drafting and reviewing P&IDs, experience with chemical plant procurement and construction

  • Basic analytical chemistry experience (NMR, HPLC, GC-MS, FTIR)

  • Strong problem-solving skill

Preferred Qualifications:

  • Experience with continuous-flow manufacturing

  • Prior experience developing with nitration chemistries, including hazardous or toxic material handling.

  • Prior experience with hazardous operations and safety reviews

 

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

ITAR Requirements

This position requires access to information and technology protected under U.S. export control laws and regulations, including the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR).
