Astracite is a climate-tech startup pioneering molten-salt electrochemical technologies to produce graphite-silicon composites for lithium-ion battery applications and recycle material from end-of-life batteries. As Process Development Engineer, you will own the development and scale-up of all downstream steps after Astracite's electrochemical deposition process.
Job Responsibility:
Develop, optimize, and scale post-processing unit operations (with emphasis on leaching and spheroidization) for Astracite's electrochemically produced materials
Design, plan, and execute lab-scale experiments to screen process conditions, study kinetics, and evaluate different chemistries and operating strategies
Scale promising concepts from lab to pilot scale, including mass/energy balance calculations and the definition of critical process parameters and operating windows
Translate product and quality requirements (particle size distribution, morphology, purity, residuals, etc.) into process specifications and operating windows
Interface with equipment manufacturers to evaluate technologies, define technical specifications, and support equipment selection and sizing for leaching, solid-liquid separation, drying, spheroidization, and auxiliary systems
Plan, supervise, and interpret trials at vendor sites, including test protocols, sampling plans, and data analysis, to de-risk equipment decisions
Support factory acceptance tests (FAT), site acceptance tests (SAT), installation, commissioning, and start-up of new post-processing equipment at Astracite
Work hands-on on pilot lines, including test execution, troubleshooting, and incremental process improvements
Collaborate with R&D on new material concepts to ensure downstream processes and equipment can meet performance and cost targets
Provide technical input for CAPEX/OPEX estimates and techno-economic evaluations of process options
Requirements:
MSc or PhD in Chemical Engineering, Process Engineering, Materials Science, Physics, Chemistry or related
2+ years hands-on experience in process development or scale-up in a relevant industry (chemicals, battery materials, minerals, powders, hydrometallurgy, or similar)
Solid understanding of unit operations such as leaching, solid-liquid separation, washing, drying, milling, and particle shaping/spheroidization
Experience with scaling processes from lab to pilot and/or industrial scale, including experimental design, data analysis, and basic process modelling or calculations
Experience with (electro)chemical process modelling is a strong plus
Comfortable working with equipment suppliers: writing specifications, discussing process guarantees, reviewing designs, and participating in tests at supplier sites
Familiarity with materials characterization techniques (e.g., SEM, ICP, etc.)
Fluent in written and spoken English
Skilled in using Microsoft Office tools, particularly Word and Excel, on Windows platforms
Strong attention to detail and willingness to learn
Good communication skills and ability to work in a startup environment
Nice to have:
Experience with (electro)chemical process modelling
Familiarity with materials characterization techniques (e.g., SEM, ICP, etc.)
What we offer:
A unique opportunity to join as one of our first employees, shape the future of breakthrough climate technologies, and grow with the company
Opportunity to work on cutting-edge climate technology
Hands-on experience with novel electrochemical systems
