What is a downstream engineer?

Downstream Engineers are professionals who work in the downstream sector of the oil and gas industry, which involves the refining of crude oil, processing of raw natural gas, and the distribution and marketing of petroleum products. They are responsible for designing, operating, and optimizing processes in refineries and petrochemical plants to ensure efficient and safe production. Downstream Engineers also work on improving product quality, reducing environmental impact, and troubleshooting operational issues. Their roles often require strong knowledge of chemical engineering, process optimization, and safety regulations.

What are some common challenges faced by downstream engineers when optimizing refinery processes?

Downstream Engineers often face the challenge of balancing efficiency, safety, and environmental compliance while optimizing refinery processes. They must troubleshoot complex systems, identify bottlenecks, and implement solutions that maximize yield without compromising product quality or safety standards. Additionally, adapting to evolving regulations and integrating new technologies, such as digital process control systems, requires continuous learning and collaboration with multidisciplinary teams. These challenges make the role dynamic and rewarding for engineers who enjoy problem-solving and innovation.

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

To thrive as a Downstream Engineer, you need a solid background in chemical or petroleum engineering, process optimization, and industrial safety, usually supported by a relevant engineering degree. Familiarity with process simulation software (like Aspen HYSYS or ChemCAD), industry standards, and certifications such as Professional Engineer (PE) are typically required. Strong analytical thinking, problem-solving, and effective communication skills help you collaborate with multidisciplinary teams and address operational challenges. These skills and qualifications are vital for ensuring safe, efficient, and compliant operation of refining and petrochemical processes.

Job description

Associate Director/Director, Downstream Processing

Summary

The Associate Director/Director, Downstream Processing (DSP) will lead the strategy, development, and execution of downstream purification processes for products made through precision fermentation, with a focus on small molecules for use as cosmetic active ingredients. This individual will serve as the organization's subject matter expert in downstream processing, guiding a team of scientists and engineers through process development at bench, pilot, and manufacturing scale. The candidate will also own the technical relationship with external Contract Development Manufacturing Organization (CDMO) and Contract Manufacturing Organization (CMO) partners, from proposal review through tech transfer and commercial scale-up to manufacturing support.

This is a hands-on leadership role that requires deep technical expertise in downstream unit operations, strong cross-functional collaboration skills, and the ability to translate laboratory-scale processes into robust, cost-effective, and scalable manufacturing solutions.

Essential Functions

  • Direct the development of downstream purification processes for fermentation-derived products, from bench scale (grams) through pilot scale (kilograms) to manufacturing scale (tons per year).
  • Provide hands-on technical expertise across downstream unit operations, including centrifugation, filtration (dead-end and tangential flow), distillation, precipitation, adsorption chromatography (HIC, IEX), liquid/liquid extraction, crystallization, and drying.
  • Establish and maintain a flexible, efficient downstream processing laboratory equipped for rapid process development, troubleshooting, and technology transfer.
  • Evaluate and manage CDMO and CMO partnerships, including authoring requests for proposals, reviewing vendor proposals, and conducting site visits and inspections.
  • Serve as the primary technical point of contact for external manufacturing partners during scale-up and manufacturing phases.
  • Author and lead technology transfer packages to CDMO and CMO partners.
  • Serve as project manager for CDMO and CMO scale-up projects, ensuring timelines, budgets, and quality standards are met.
  • Provide experimental, modeling and statistical capabilities to ensure successful process transfer and robustness at scale
  • Identify, specify, and oversee the purchase of scale-relevant downstream processing equipment for external manufacturing partners.
  • Partner with quality, regulatory, and supply chain teams to ensure downstream processes meet all applicable standards.
  • Communicate technical progress, risks, and recommendations to senior leadership.
  • Lead and mentor a team of downstream process development scientists and engineers
  • Set the technical direction and strategic priorities for the Downstream Processing function.
  • Define and track key performance indicators for the team, including yield, purity, scalability, and cost.
  • Collaborate closely with upstream process development and strain engineering leads to align on integrated process development strategies.

  

Education and Experience

  • PhD + 10 years of experience; OR Master's Degree + 16 years of experience; OR Bachelors Degree + 18 years of experience.
  • Significant experience in downstream process development for fermentation-derived products, with demonstrated expertise across lab, pilot, and manufacturing scales.
  • Demonstrated expertise in downstream unit operations, including centrifugation, filtration, distillation, precipitation, chromatography, liquid/liquid extraction, crystallization, and drying.
  • Experience managing or leading technical teams, including mentoring scientists and engineers.
  • Proven experience authoring and executing technology transfers to CDMO or CMO partners.
  • Experience serving as a technical project manager for external scale-up or manufacturing projects.
  • Strong written and verbal communication skills, with the ability to convey technical information to both technical and non-technical stakeholders.
  • Experience evaluating and selecting CDMO or CMO partners, including RFP authorship and site audits.
  • Familiarity with mass balance review and master batch record oversight.
  • Experience specifying and procuring scale-relevant process equipment.
  • Background in microbial (bacterial and yeast) fermentation DSP processes, of both hydrophobic and hydrophilic target compounds.

 

Travel Requirements

This role requires travel of approximately 20% to support CDMO and CMO site visits, inspections, technology transfer activities, and on-site collaboration during scale-up and manufacturing phases. Travel may include both domestic and international destinations, depending on the location of manufacturing partners.
