Process Engineer Intern

Location: Amsterdam, Netherlands (in-person)

Duration: 6 months (full time)

Start date: June-November

About the Role

Brineworks is developing ultra low-cost direct air capture (DAC) for carbon removal and utilisation. We are a climate tech start-up headquartered in Amsterdam, the Netherlands, with an

international team of 15 with expertise spanning chemistry, engineering, policy, business, and strategy.

We are seeking a motivated process engineer intern to join our team. This is a hands-on role that bridges design engineering and pilot plant operations. You will contribute to the piping and instrumentation design of a DAC facility while also supporting data processing and day-to-day operation of our DAC pilot plant. This position offers a unique opportunity to gain experience across the full lifecycle of climate technology—from concept design through real-world testing.

Key Responsibilities

Piping & Instrumentation Design (DAC Plant)

• Assist in developing and reviewing Piping & Instrumentation Diagrams (P&IDs) for the DAC plant
• Support pipe sizing, material selection, and routing studies in coordination with senior engineers
• Help define instrument specifications (sensors, transmitters, control valves) and prepare instrument data sheets
• Contribute to equipment lists, line lists, and valve schedules
• Participate in design reviews, HAZOPs, and constructability assessments
• Coordinate with process, mechanical, and controls teams to ensure design consistency

Pilot Plant Operations & Data Processing

• Assist with the daily operation of the DAC pilot plant, including startup, shutdown, and monitoring procedures
• Collect, clean, and organize operational data from the pilot plant’s sensor and control systems
• Develop and maintain dashboards, automated scripts, or databases for data visualization and trend analysis
• Perform data quality checks and flag anomalies for engineering review
• Support test campaign planning, execution, and post-test analysis
• Document operating procedures, lessons learned, and performance results

Qualifications - Required

• Currently pursuing a B.S. or M.S. in Chemical Engineering, Mechanical Engineering, Process Engineering, or a related discipline
• Foundational knowledge of process engineering principles (mass/energy balances, thermodynamics, fluid mechanics)
• Familiarity with P&ID symbology and reading engineering drawings
• Proficiency in Python, MATLAB, or ANY similar tools for data analysis
• Strong attention to detail and ability to work in a team environment
• Interest in climate technology, carbon capture, or clean energy

What You’ll Gain

• Real-world experience in both design engineering and plant operations within the DAC industry
• Mentorship from experienced process, piping, and controls engineers
• Exposure to the full project lifecycle—from P&ID development to pilot plant testing
• Skills in data engineering, process design, and operational troubleshooting
• The opportunity to contribute meaningfully to climate change mitigation
• Free lunch, plus unlimited snacks and drinks in the office
• Paid internship
