Senior R&D Chemist

Responsibilities

• Method Development & Validation
• Lead the design, development, optimisation, and validation of analytical chemistry, electrochemical, and wet-chemistry methods for real-time, at-source contamination monitoring across water and engineered fluid applications.
• Project Ownership & Technical Decision-Making
• Take ownership of assigned R&D projects or technical workstreams, including experimental planning, prioritisation, risk assessment, troubleshooting, data interpretation, and recommendation of next steps. Make sound technical decisions based on evidence, project needs, and practical constraints.
• Analyser & Method Integration
• Testing, QC & Documentation
• Define, plan, and execute laboratory and field testing protocols, calibration routines, validation studies, and quality-control procedures. Maintain clear, structured, and auditable documentation of experimental work, conclusions, and technical decisions.
• Troubleshooting & Continuous Improvement
• Investigate anomalies, interferences, performance drift, reproducibility issues, and unexpected experimental outcomes. Lead root-cause analysis and drive improvements in methods, materials, workflows, and processes.
• Cross-Functional Collaboration & Technical Guidance
• Collaborate with the wider R&D and engineering teams to align chemistry development with product, field, and customer requirements. Provide technical guidance to junior team members or supporting staff where needed.
• Regulatory, Pilot & Customer Support
• Support certifications, pilots, and customer deployments by providing technical inputs, test data interpretation, experimental evidence, and chemistry-related insights to internal teams and external stakeholders.
• Qualifications and Skills
• Bachelor's or Master's degree in Chemistry, Analytical Chemistry, Materials Science, Chemical Engineering, Physics, or a related field; a Master's degree is preferred.
• Minimum 6 years of relevant experience in R&D, analytical chemistry, electrochemistry, method development, environmental analysis, industrial chemistry, instrumentation, or a related technical field.
• Strong background in Analytical Chemistry is required, including experience with chemical analysis, method development, calibration, validation, troubleshooting, and interpretation of experimental results.
• Experience in Electrochemistry is highly preferred.
• Broad chemistry experience is desirable, especially across wet chemistry, analytical methods, laboratory testing, materials, reagents, instrumentation, or applied R&D.
• Strong hands-on laboratory skills and willingness to work directly with experiments, instruments, samples, reagents, and prototypes.
• Ability to independently plan experiments, analyse results, identify issues, and make evidence-based technical decisions.
• Strong critical thinking, problem-solving ability, attention to detail, and scientific judgment.
• Experience taking ownership of projects, technical workstreams, or complex experimental tasks from planning through execution and reporting.
• Proactive, responsible, and comfortable working in a fast-paced startup environment with changing priorities and practical constraints.
• Ability to collaborate effectively with chemists, engineers, software/data teams, and non-technical stakeholders.
• Strong communication skills, with the ability to present technical ideas, experimental results, risks, and recommendations clearly.
• Experience with data analysis tools or scientific software such as Excel, Python, MATLAB, Origin, or similar platforms would be an advantage.
• Exposure to optical, photonic, or other instrument-based analytical methods would be a plus but is not required.
• Join us in developing innovative technologies that help create a cleane

Additional Information

Position Overview: As a Senior R&D Chemist at Aprisium, you will play a key role in developing, validating, and translating analytical chemistry methods into robust, real-world contamination monitoring solutions. This role is intended for an experienced chemist who can work independently, lead technical workstreams, make evidence-based decisions, and take ownership of project outcomes. The ideal candidate will bring strong experience in analytical chemistry, with electrochemistry being highly preferred, and will be comfortable working hands-on in the laboratory while also guiding experimental strategy, troubleshooting complex problems, and collaborating across chemistry, hardware, fluidics, electronics, and data teams. This is a hands-on R&D role in a fast-paced startup environment, suited for someone proactive, technically strong, adaptable, and ready to take responsibility for both execution and decision-making.
