Are you passionate about translating real plant operating conditions into outstanding biotechnology performance in ethanol fermentation?
You will be part of the Technical Service team at our H&B team, working in close collaboration with Sales, Business Development, and Applications to deliver hands‑on, high‑impact technical support to ethanol producers across LATAM South.
Where You’ll Make a Difference
In this role, you will provide advanced technical service and process consultancy to customers in the ethanol industry, with a strong focus on how plants are operated to enable optimal enzyme, yeast, and microbiology performance.
You will act as a trusted technical partner throughout the full operational lifecycle — from start‑ups and commissioning to steady‑state operations, expansions, and process changes — ensuring operating conditions remain aligned with biotechnology performance windows.
Key areas where you will create impact include:
Leading technical diagnostics and operational process consultancy in starch‑to‑ethanol processes, including liquefaction, saccharification, and fermentation performance under real operating conditions
Optimizing enzyme and yeast performance by aligning operating practices with biological requirements
Assessing microbiological risks and supporting contamination mitigation strategies
Improving fermentation stability, yield, and productivity through operational adjustments
Performing root cause analysis of operational deviations impacting biotechnology performance, with focus on operations rather than equipment design
You will also play a critical role during:
New ethanol plant start‑ups and commissioning phases
Capacity expansions, debottlenecking initiatives, and operational ramp‑ups
Feedstock changes, process transitions, and shifts in operating strategies
By applying your engineering background, you will translate plant constraints into clear, actionable operating recommendations, acting as a bridge between process reality and biotechnology performance — without acting as a plant design authority.
What Makes You the Right Fit
You bring a strong combination of engineering expertise, field experience, and operational mindset, allowing you to turn complex plant conditions into practical solutions.
You have:
A degree in Engineering (Chemical, Biological, Biochemical, or related disciplines)
Experience working in ethanol plants and industrial fermentation environments
Strong exposure to plant operations, start‑ups, commissioning, and troubleshooting
Solid understanding of fermentation processes, microbiology, enzymes, and yeasts
The ability to connect operating conditions with biotechnology performance and limits
Strong analytical, problem‑solving, and root cause analysis skills
Clear communication skills, from shop‑floor discussions to executive‑level conversations
A hands‑on, pragmatic, and customer‑oriented approach
How You Would Stand Out
You will stand out in this role if you:
Translate technical results into measurable business impact, including ethanol yield, productivity, process robustness, microbiological control, and cost efficiency
Structure and execute technical action plans with defined KPIs and validate results in the field
Produce clear, decision‑oriented deliverables such as performance reports, start‑up summaries, troubleshooting analyses, and executive insights
Act as a strong technical partner to Sales and Business Development by supporting customer engagements, providing competitive technical assessments, and enabling value‑based selling
Continuously build technical capability by sharing knowledge with customers and internal teams on fermentation fundamentals, enzyme and yeast behavior, and best operational practices
