What are some common challenges Process Systems Engineers face when working on multidisciplinary project teams?

Process Systems Engineers often collaborate with professionals from mechanical, electrical, and instrumentation disciplines, which can present challenges in aligning project objectives and schedules. Effective communication is essential to ensure all team members understand process requirements and constraints, especially when integrating new technologies or optimizing existing systems. Additionally, balancing safety, efficiency, and cost considerations while meeting regulatory standards can require creative problem-solving and strong project management skills.

What is a Process Systems Engineer?

A Process Systems Engineer is a professional who designs, analyzes, and optimizes complex industrial processes using principles from engineering, mathematics, and computer science. They work to improve efficiency, safety, and sustainability in industries such as chemical manufacturing, oil and gas, pharmaceuticals, and food processing. Their responsibilities often include process modeling, simulation, control systems design, and troubleshooting of production systems. By integrating various technologies and methodologies, Process Systems Engineers help organizations achieve operational excellence.

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

AspectProcess Systems EngineerChemical Engineer
Required CredentialsBachelor's in Chemical, Mechanical, or Industrial Engineering; often certifications in process optimizationBachelor's in Chemical Engineering; licensure optional for certain roles
Work EnvironmentIndustrial plants, manufacturing facilities, process design teamsResearch labs, manufacturing plants, design firms
Industry UsageProcess optimization, plant operations, systems designProduct development, process design, chemical production

Process Systems Engineers focus on designing, analyzing, and optimizing manufacturing processes and systems, often working closely with plant operations. Chemical Engineers have a broader scope, including chemical reactions, product development, and process design. While both roles require similar educational backgrounds, Process Systems Engineers specialize in process efficiency and systems integration within industrial settings.

Job description

Thanks for your interest in Oklo!  We are searching for a Process Engineer to join our engineering team. We are looking to fill this position immediately.

Position Description

Process Engineers at Oklo are responsible for the design, engineering analyses, systems engineering, specifications development, and operations of the fluid and power process systems used in Oklo's power plants.

Specific responsibilities may include:

  • Design fluid and process systems including: piping, valves, compressors, pumps, and heat exchangers

  • Define process equipment architecture, specifications, operational modes, and performance criteria
  • Design, assemble, and operate prototypes to use for iterative design refinement
  • Generate documentation guiding the system layout, fabrication, installation, commissioning, operation, and maintenance of process equipment
  • Serve as process system owner through multiple lifecycle stages

  • Generate technical documentation to be included in regulatory filings

  • Work with external vendors on process equipment analysis, procurement, and testing
  • Document work using modern tools and techniques, and compose well-written, thoughtful technical reports

Competencies

We are looking for a Process Engineer that is:

  • Experienced in fluids/process system design, power generation, heat transfer equipment, and/or systems engineering

  • Passionate about clean energy

  • Passionate about making advanced fission a reality

  • Willing and able to learn quickly

  • Willing to think differently and do things in new ways 

  • Comfortable in a fast-paced, highly iterative startup environment

  • Excited to think creatively, critically, and reflectively about the problems they are solving while not leaning only on what has been done before 

  • Willing to propose novel and creative solutions to technical problems

  • An excellent writer who can write in a modern active voice, so make your cover letter compelling and write it well!

  • Able to communicate technical content and results verbally

Who you are:

A startup person: You aren't driven by titles or hierarchy, and prefer efficiency to excess process. You don't need or expect to have a lot of guidance but you enjoy working in a fast-paced team. If you prefer the culture and feel of a large organization, that is great, but you likely won't enjoy working with us! There is plenty of important work and plenty of good opportunities with organizations like that.

Motivated: You are self-motivated. You bring an enthusiasm to the team, and imbue a sense of passion that goes beyond clocking in and clocking out. This isn't about a fake or arbitrary "pieces of flair" mentality or lack of work-life balance! It is about being a part of the vision and feeling a part of reaching team goals.

A team-player: Oklo genuinely is a team. We aren't about taking credit for ourselves, and we aren't about pushing blame to others. We do incredible things because we work as a team.

An excellent communicator: We need a person who is not only technically competent but also a clear and upbeat communicator.

Creative: Being creative means that when things fall outside clear scopes or processes or problems arise without clear solutions, you are able to identify it as well as invent ways to solve a problem or fill a need without micromanagement. The successful person in this job will not only be creative, but also enjoy being creative and solving open-ended problems which may change day-by-day.

Detail-oriented: This focus is a big part of excellence, consistency, and quality. Excellent grammar and spelling matter for both good communication as well as the image of the company that we put forward.

Minimum Qualifications:

  • Engineering education, potentially Mechanical, Chemical, Petroleum, or Aerospace

  • Experience performing design or modification engineering on process equipment, such as that used in the petroleum, nuclear, petrochemical, or pharmaceutical industries

  • Broad familiarity with engineering principles, and having strong systems engineering and operations intuition

About Oklo travel requirements:

Oklo requires remote employees to travel to headquarters (Santa Clara, CA) twice a quarter annually, based on business or team needs, including attendance at team meetings, off-sites, and other company events or gatherings. For the first two weeks of onboarding, employees are required to be in person at headquarters in Santa Clara, CA.

About Oklo compensation:

Salary: $80,000-$155,000

Salary may fall outside of the range provided and will be dependent on applicant experience.

Oklo offers flexible time off, equity, competitive pay, 401k, health insurance, FSA, flexible work hours, and other benefits.
