Chemical Process Reasoning Reviewer

IXO is engaging specialists to evaluate chemical-process decisions that are technically sound and safe at the intended scale. Your contribution is technical work: make the reasoning inspectable, identify substantive errors and provide evidence that supports a reliable assessment.

Work you will do

• Develop scenarios from material and energy balances through process design or safety review.
• Write reference explanations that connect the calculation, process assumptions and practical operating limits.
• Evaluate model outputs for engineering accuracy, feasibility and safety, identifying recommendations that would fail when implemented or scaled.

Required background and routes

• A chemical-engineering or closely related degree and two or more years in process, plant or product engineering, with depth in scale‑up, safety or process design.

Preferred background

• PE or process‑safety credentials, HYSYS/Aspen Plus simulation, and regulated sectors such as petrochemicals or pharmaceuticals.

Deliverables

Submit the completed technical artifact or assessment with its supporting evidence, explicit assumptions, reproducible checks where applicable, and concise reasons for each material judgment. Address review findings within the agreed scope.

Location and schedule

Remote assignments are scheduled by agreement, with no guaranteed weekly volume. Availability planning can include 10 hours per week depending on the track. IXO confirms the applicable timing before work.
