Managing Scientist- Product

Responsibilities for this role will include:

• Provide technical leadership in the development, validation, and optimization of cement formulations, with emphasis on mineral processing, milling, particle technology, and suspension rheology. 
• Lead team and coordinate multiple R&D workstreams simultaneously, ensuring alignment with product development priorities and timelines. Provide guidance, mentorship, and technical oversight to other scientists and engineers. 
• Partner closely with Pilot / Process R&D and other cross-functional teams to establish tight feedback loops between laboratory results, process constraints, and scale-up learnings. 
• Design, execute, and interpret experimental programs involving milling and grinding, rheology, and cement property measurements; analyze data and clearly communicate results and implications. 
• Develop and execute rheological testing strategies to characterize flow behavior, thixotropy, structuration, particle interactions and additive/admixture compatibility in cementitious systems. 
• Evaluate and optimize grinding and classification parameters to control particle size distribution, surface area, and morphology in support of fresh and hardened cement performance. 
• Contribute to cement performance and technology development through literature review, balancing chemistry/processing/manufacturability consideration, competitive analysis, and engagement with external experts, suppliers, and industry partners. 
• Develop, validate, and implement new test methodologies to characterize cement performance, processing behavior, and scale-up risks. 
• Maintain, calibrate, and expand laboratory capabilities, particularly in rheology and particle engineering. 
• Author technical white papers, internal reports, and patent applications to document and protect Sublime’s innovations. 
• Champion safety and responsible laboratory practices, particularly when developing new experimental methods and processes. 
• Foster a collaborative, inclusive, and innovative team culture, setting expectations for rigor, accountability, and continuous learning. 

Requirements Include:

• Ph.D. in Materials Science & Engineering, Chemical Engineering, Civil Engineering, or related discipline. 
• 2+ years of industry experience in research and development, materials engineering. 
• Strong technical foundation in inorganic materials and particle-based systems, with demonstrated expertise in: Mineral processing and milling, Particle technology and PSD control, Suspension rheology and rheometry. 
• Proven ability to develop and interpret structure–property relationships for cementitious systems to guide material design and performance optimization. 
• Hands-on experience with characterization techniques such as laser diffraction, TGA, XRF, XRD, BET, optical microscopy, and/or SEM. 
• Experience in leading research projects involving hypothesis-driven experimentation, DOE, and statistical data analysis to measure physical and chemical properties relevant to cementitious materials. 
• Demonstrated leadership and project management skills, including the ability to prioritize work, develop and manage complex workflows, and drive progress across multiple R&D initiatives. 
• Strong written and verbal communication skills, with the ability to present technical findings clearly to diverse audiences and build effective cross-functional relationships across disciplines and organizational boundaries. 
• Strong attention to detail and data quality, paired with the ability to maintain a system-level, strategic perspective. 
• Ability to thrive in a dynamic, collaborative and inclusive startup environment with adaptability, professionalism, and a positive “can-do" attitude.
