Start date target: February 2026
Mission / role summary: Lead the deployment of a robust MRV (Measurement, Reporting, Verification) carbon accounting protocol for the biomineralization process; support third-party certification (e.g. for carbon credits) and ensure the geochemical integrity of the system. Work closely with Julien (Head of Science) as a core technical function of the certification pathway.

Key Responsibilities

• Design, implement, and validate MRV protocols adapted to Bloomineral’s biomineralization process (e.g. measurement of dissolved inorganic carbon, isotopic tracers, flux balances, uptake rates).

• Develop sampling, monitoring, and analytical plans (lab and field) to capture carbon fluxes, process losses, uncertainty, and leak detection.

• Interface with certification bodies / auditors; prepare documentation, data packages, audits, verifications.

• Provide geochemical and organic chemistry insight to the process — e.g. equilibria, kinetics, speciation, precipitation, by-product formation, trace contaminants.

• Work with the R&D / process teams to diagnose process deviations, mass balance anomalies, side reactions, scaling effects.

• Establish quality assurance / quality control (QA/QC) protocols for analytical data, calibrations, standard materials, uncertainty propagation.

• Collaborate with Julien (Head of Science) and other stakeholders to integrate MRV outcomes into the business / IP / carbon credit strategy.

Requirements / Profile

• PhD, or strong postdoctoral / senior experience, in geochemistry, geochemistry / geochemistry-inspired environmental science, or a closely aligned field (e.g. environmental chemistry, isotope geochemistry).

• Deep knowledge of aqueous geochemistry, carbonate systems, isotope geochemistry, speciation, kinetics.

• Hands-on experience with analytical instrumentation (e.g. IC, ICP, TOC / TIC, mass spectrometry, isotopic analysis, spectrophotometry, titrations).

• Prior experience in carbon cycle science, carbon accounting, greenhouse gas quantification, or MRV is highly desirable.

• Understanding of uncertainty analysis, error propagation, statistical analysis of measurement data.

• Ability to translate complex geochemical results into audit-grade data for third-party verification.

• Excellent communication skills: ability to document protocols, present to auditors / external stakeholders, interface across teams.

• Highly self-driven, hands-on, capable of working at pilot / field scale under non-ideal conditions.
