Berkeley, CA /
R&D – Downstream Process Development and Scale-Up /
Full Time
Demetrix is a start-up in the San Francisco Bay area that is making nature’s medicines in a smart and responsible way via synthetic biology. The Scientist position will be part of the Downstream Process Development & Scale-Up (DSP) team and will lead the development of robust, scalable downstream processes at bench-scale, oversee the validation and characterization of these processes, and support the transfer of these processes to pilot and manufacturing scale. You will be part of an interdisciplinary team of fermentation engineers, automation engineers, software engineers, analytical chemists, and molecular biologists working to rapidly develop microbial strains to produce natural product medicines.

Your Impact:

    • Design, lead and assist in bench/pilot-scale studies to support downstream process development, optimization, characterization and scale-up. Develop protocols using a wide range of purification & separation methods.
    • Design, review, process, and report data appropriately. Emphasis on process flow diagrams, yields, mass & energy balances, and cost modeling. 
    • Propose, establish, and maintain equipment to grow Demetrix capabilities for purification, separations, and characterization. Design and carry out small-scale experiments to expand knowledge base of Demetrix product suite. 
    • Conceive ideas to reduce the cost of manufacture of product, develop and implement experimental plans to test and evaluate feasibility of ideas.
    • Support tech transfer of developed processes to allow for scale up at contract research/ manufacturing organizations (CROs/CMOs). Interface, coordinate and provide on-site support at CROs/CMOs as required.
    • Oversee downstream process operations for robustness testing of established processes.
    • Document experimental studies in reports, datasheet, and presentations and author/edit standard operating procedures (SOPs). Present experimental work to internal and external collaborators.
    • Mentor and direct junior scientists/engineers in bench-scale downstream process development.
    • Coordinate with upstream fermentation group for starting material for downstream process development work. 
    • Travel (Up to 15%) may be required.

Your Experience:

    • Degree in the Biological or Chemical Science/Engineering field.
    • 0-3 years (PhD) / 5+ years (Masters) / 8+ years (Bachelors) of relevant industrial experience in downstream process development and/or purification of small molecules from complex matrices (e.g. fermentation broth).
    • Hands-on experience with wide-range of separation and purification technologies (centrifugation, filtration [both dead-end and cross-flow], liquid-liquid extraction, precipitation, crystallization) desired. 
    • Experience with tech transfer, CRO/CMO support, and scale-up support of established processes is a plus.
    • Experience in small-scale operations / manufacturing is a plus.
    • Experience overseeing direct reports desired. 
    • Ability to work both collaboratively and independently as required.
    • Strong planning, organizational, time management, and communication skills.

Some more about Demetrix:

Nature is a rich source of ingredients. Inconsistent quality and supply, along with inaccessibility of rare substances, mean it’s not always an ideal source to meet the world’s needs.  

Demetrix helps customers across the globe produce more for less.

Biotechnology can help by enabling access to more rare and powerful products. With less environmental impact and less cost than traditional methods. Which can lead to more happy, healthy lives.

Demetrix gives you:
Expensive and hard-to-find ingredients at your fingertips, sustainably and affordably  
High ingredient purity without residual chemicals or pesticides
Affordable access that is quickly scalable as your business grows
Product consistency and a reliable, global supply
A sustainable solution with a small environmental footprint

Currently, we’re building a product pipeline of cannabinoids, the active compounds in the cannabis plant. Humans have been relying on cannabinoids for health and medicinal purposes for centuries.
Although there are more than 113 unique cannabinoids, very few have been studied. That’s because they are present in such low quantities in the plant. We can produce even the rarest cannabinoids at high purity and volumes. What this will do is enable research for health benefits and, ultimately, provide affordable access to the compounds.
