Spore.Bio is a deeptech startup building a new generation of microbiological quality control for the Pharmaceutical, Food & Beverage, and Cosmetics industries.

Traditional microbiology methods require long incubation times before manufacturers can make critical decisions about product safety and quality. At Spore.Bio, we are developing a radically faster approach combining microbiology, advanced optical technologies, and machine learning to detect and characterize microbial contamination.

We are looking for a Senior R&D Microbiology Engineer to join our Microbiology team and take a leading scientific role in the development, validation, and deployment of our technology.

You will work at the intersection of microbiology, data science, hardware, and product development, tackling complex scientific challenges and helping translate our technology from experimental concepts into robust solutions used in industrial environments.

About the role

As a Senior R&D Microbiology Engineer, you will own complex scientific topics and play a key role in defining how microbiology is approached across our technology and products.

• 
  

• Scientific Strategy & Experimental Design: Own microbiology workstreams from scientific question to conclusion. Define hypotheses, experimental strategies, methodologies, acceptance criteria, and validation plans to answer complex technical and product questions.

  
  

• Method Development & Validation: Develop and challenge microbiological methods across different microorganisms, matrices, and use cases. Build robust experimental approaches and ensure their reproducibility, statistical relevance, and scalability.

  
  

• Data Interpretation & Scientific Decision-Making: Analyze complex experimental datasets, identify patterns and limitations, and translate results into clear scientific conclusions and product recommendations. Use data to challenge assumptions and guide technical decisions.

  
  

• Product Development & Tech Transfer: Translate laboratory results into robust protocols and methodologies that can be deployed in real industrial environments. Work closely with Product, Machine Learning, Hardware, and Software teams to bridge fundamental microbiology and product performance.

  
  

• Technical Leadership: Act as a scientific reference within the Microbiology team. Review experimental approaches and results, raise the scientific bar, and mentor engineers, scientists, and technicians on complex microbiology topics.

  
  

• Cross-Functional Project Leadership: Lead strategic R&D projects involving multiple technical teams. Structure priorities, identify scientific risks, coordinate stakeholders, and drive projects toward clear technical milestones.

  
  

• Industrial & Customer Applications: Contribute to the adaptation and validation of our technology across Pharma, Cosmetics, and Food & Beverage applications, including challenging microorganisms, matrices, and industrial testing environments.

  
  

• Quality, Compliance & Traceability: Ensure scientific rigor, traceability, and reproducibility while helping design processes that remain compatible with the speed and constraints of a fast-growing startup.

  
  

• Scientific Communication & External Collaboration: Represent Spore.Bio in technical discussions with customers, scientific partners, and industry experts. Contribute to scientific documentation, publications, patents, conferences, and regulatory discussions when relevant.

  
  

About you

We are looking for someone with strong scientific depth who is comfortable taking ownership of complex and ambiguous microbiology problems.

• 
  

• Academic Background: PhD in microbiology, biotechnology, biological sciences, or a related discipline, or a Master’s degree combined with significant relevant industry experience.

  
  

• Experience: Typically 5+ years of relevant experience in microbiology R&D, applied research, method development, or industrial microbiology. Experience in Pharma, Cosmetics, Food & Beverage, diagnostics, or biotechnology is particularly relevant.

  
  

• Microbiology Expertise: Strong hands‑on expertise in microbiological methods, microbial culture, enumeration and detection techniques, contamination monitoring, and experimental design.

  
  

• Method Development: Demonstrated experience developing, optimizing, or validating microbiological methods and investigating complex experimental results.

  
  

• Scientific Leadership: Proven ability to independently structure scientific problems, make technical decisions, challenge experimental approaches, and drive R&D pro
