Position Summary
Biomason is seeking a Research Scientist/Senior Engineer specializing in Concrete, to help lead the development, testing, and optimization of bioconcrete products incorporating biocement. This role is highly applied, bridging laboratory research with real-world product development. The ideal candidate will have expertise in aggregate characterization, concrete mix design, statistical experimental design and modeling, and mechanical/durability testing of concrete products. This position reports to the Vice President of R&D and may require occasional international travel to support partnerships, pilot projects, and scale-up initiatives.

Key Responsibilities

• Develop and optimize bioconcrete formulations incorporating biocement for strength, durability, and performance

• Apply statistical methods (DOE, regression modeling, multivariate analysis) to design experiments and build predictive models

• Characterize concrete materials using industry-standard testing (ASTM, ACI, EN, and other international standards)

• Translate lab-scale findings into pilot- and production-scale applications

• Collaborate with cross-functional R&D, engineering, and manufacturing teams, as well as external partners

• Prepare clear technical documentation and communicate findings to both technical and non-technical stakeholders

• Remain current with advances in cement chemistry, biomineralization, and sustainable construction materials

Qualifications

• M.S. or Ph.D. in Civil Engineering, Concrete Science, Materials Science, or a related field

• Minimum of 3 years of direct experience in biocement, bioconcrete, or cementitious material research, product development, or testing

• Hands-on experience with pre-cast concrete manufacturing (wet and/or dry) preferred; RMX concrete production experience a plus

• Strong background in statistical experimental design (DOE) and computational/data modeling

• Experience in scaling laboratory methods to pilot or production environments

Competencies

• Strong analytical thinker with creative problem-solving skills

• Organized and detail-oriented; able to manage multiple priorities in a fast-paced environment

• Excellent oral and written communication skills

• Collaborative team player with the ability to work independently

• Commitment to laboratory and site safety protocols

Physical Demands

• Ability to stand, walk, and work in laboratory and pilot plant environments for extended periods

• Ability to lift up to 25 pounds occasionally

• Manual dexterity for handling laboratory equipment and test specimens
