About The Position

We are seeking a Chemical Engineering Associate to support experimental and
process development work across our in-house reactor systems. This is a hands-on
role focused on executing and supporting chemical processes at the pilot scale,
with a clear path toward increased ownership in experimental design and process
development over time.

This position is ideal for a recent Chemical Engineering graduate who is excited
to apply core engineering fundamentals in a practical, fast-paced lab
environment. You’ll work closely with experienced engineers and scientists to
help develop and scale a unique chemical process that is central to our product.

Requirements

• Bachelor’s (or Master’s) degree in Chemical Engineering
• Strong foundation in core chemical engineering principles (e.g., reaction engineering, transport phenomena)
• Hands-on experience from academic research, labs, or internships
• Comfortable working in a lab environment with chemical processes and equipment
• Detail-oriented with a focus on safety and execution quality
• Able to manage time effectively and follow direction while building toward independence
• Willing to occasionally adjust schedule to support longer-running experiments

Nice To Haves

• Experience working with reactors, pressure vessels, or similar equipment
• Familiarity with organic solvents and standard lab glassware
• Exposure to polymer synthesis or related chemistry
• Basic understanding of analytical techniques (e.g., chromatography)

Responsibilities

• Operate and support experiments on pilot reactor systems, including setup, execution, and teardown
• Follow established procedures to run chemical processes safely and consistently
• Assist in monitoring and documenting key process parameters (e.g., temperature, time, agitation, catalyst loading)
• Analyze experimental data and contribute to process understanding and optimization efforts
• Support general lab operations, including equipment preparation, cleaning, and organization
• Collaborate with engineering and R&D teams to execute planned experiments and process improvements
