Start date target: July 2026
Mission / role summary: Provide support in the design, modeling, automation, and reliability improvements for pilot systems (reactors, flows, controls) to scale biomineralization toward industrial readiness. Focus on mechanical / fluid systems, automation integration, and ensuring robustness of pilot operations.

Key Responsibilities

• Assist in the design and sizing of reactors, flow networks, piping, pumps, valves, instrumentation, fluid handling subsystems.

• Support the development of control / automation strategies: sensor integration, SCADA, data acquisition, feedback loops.

• Run computational fluid dynamics (CFD), hydrodynamic modeling, mass / heat transfer modeling as needed.

• Help in instrument selection, sensor calibration, piping layout, and mechanical design under supervision.

• Prepare process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), and process documentation.

• Support reliability engineering: fault mode / failure mode analysis, predictive maintenance, robustness checks.

• Assist in commissioning, debugging, and optimization of pilot systems.

• Work with R&D, geochemistry, and data teams to integrate measurement loops and ensure process–MRV alignment.

• Document design decisions, simulation results, assumptions, and routine operating procedures (SOPs).

What We’re Looking For

• Engineering student (undergraduate or master’s level) in mechanical engineering, chemical engineering, process engineering, fluid mechanics, or a similar field.

• Strong foundation in fluid mechanics, thermodynamics, heat & mass transfer, reaction engineering.

• Proficiency in modeling tools (CFD, process simulators), mechanical CAD (e.g. SolidWorks, AutoCAD), flow/hydraulic modeling.

• Some knowledge or experience with instrumentation, sensors, control systems, automation, PID control is a plus.

• Analytical mindset, attention to detail, ability to learn quickly.

• Good communication skills, ability to document clearly, work in an interdisciplinary environment.

• Ideally, prior internship or coursework in bioprocessing, environmental / water / reactor systems, or pilot-scale systems.

Why Join Bloomineral

• Gain hands-on experience industrializing a new carbon-negative materials platform

• Work on real industrial challenges, not theoretical exercises

• Be part of a tight-knit, interdisciplinary team where interns take real ownership

• Operate within the French innovation ecosystem and collaborate with leading climate science institutions

• Help shape how carbon becomes a building block rather than a liability

We care more about curiosity, rigor, and drive than about checking every box. If our mission resonates with you but your profile doesn’t match every single line above, apply anyway. We’re building a diverse, thoughtful team and we know great people don’t all look the same on paper. If you’re excited about turning carbon into materials the world can build with, we’d love to hear from you.
