BIOWEG is seeking a Scientist to join our R&D team. In this role, you will improve the economics and robustness of our bacterial fermentation processes while leading proof-of-concept studies that expand our product portfolio. You will own experiments end to end, from experimental design and execution to data analysis, working hands-on with bacterial systems and translating your findings into practical process improvements.
If you are passionate about applying biotechnology to develop sustainable materials and enjoy working in a dynamic startup, we'd love to hear from you. Join us and help shape the next generation of bio-based solutions.
-
Plan and execute fermentation R&D campaigns focused on cost reduction and performance improvement (DoE / data-driven iterations)
-
Optimize strains, media, and process parameters while tracking key fermentation variables and defining clear success metrics
-
Design, run, and troubleshoot lab and pilot-scale fermentations (setup, monitoring, sampling and post-run analysis)
-
Analyze fermentation samples (e.g., metabolite/product profiling, process monitoring; HPLC implementation, execution and interpretation)
-
Improve experimental throughput and handover (parallelization, standardized workflows, faster R&D-to-production transitions)
-
Support scale-up and tech transfer by translating findings into repeatable protocols and practical recommendations
-
Maintain strong documentation and quality practices (experimental plans, protocols, batch records, validation-style reporting)
-
Champion aseptic technique and lab safety and contribute to improving SOPs
-
MSc or PhD in Biotechnology, Microbiology, Biochemical Engineering, Fermentation Technology, Food Technology, or related
-
MSc with at least 4 years or PhD with at least 1 year hands-on applied/industrial fermentation experience (lab-scale; pilot exposure is a plus)
-
Proven ability to optimize and troubleshoot fermentation processes (not just run them)
-
Strong data analysis and scientific communication to turn unexpected runs into decisions
-
Analytical experience (HPLC): implementing and running methods, interpreting chromatograms, reporting results clearly
-
Structured, proactive working style with ownership, prioritization, and delivery mindset
-
Comfortable taking end-to-end ownership in a small-team lab and start-up environment
-
Excellent written and verbal communication skills in English
Strong plus (preferred)
-
Experience with bacterial cellulose or closely related microbial production systems
-
Experience with valorization of side streams / process sustainability improvements (turning “waste” into value)
-
Familiarity with bioacids and/or microbial preservation systems for food or cosmetics
-
Comfort working across disciplines (R&D, scale-up, operations)
How you’ll be successful in the first months (clear outcomes)
-
Execute a repeatable experimental pipeline while further improving it(templates, key KPIs, sampling plan, reporting format).
-
Deliver at least one cost-reduction / productivity improvement supported by data.
-
Produce scale-up ready recommendations(what to change, why, expected impact, and risks).
BIOWEG is a purpose-driven company developing bio-based alternatives to fossil-based ingredients using Biotech and Green Chemistry.
