About the role
Site Engineering Manager
Mantel is developing the first molten-salt-based carbon capture technology designed to operate at the high temperatures found inside boilers, kilns, and furnaces – enabling highly efficient carbon capture that has not been possible until now. Carbon capture can be applied across industries to reduce emissions and achieve net-negative emissions. By solving for efficiency Mantel can cut costs substantially, unlocking carbon capture’s role in reaching net zero emissions by 2050. To learn more, go to: https://www.mantelcapture.com/
Role Overview
The Site Engineering Lead is Mantel's technical presence on the ground. You'll work closely with the VP of Engineering and Commissioning Director on-site to support execution of Mantel's first demonstration project - managing day-to-day technical activities and making sure nothing falls through the cracks in the field.
What You'll Do
- Demonstration Project Support Support engineering execution on-site from test plan through steady-state operation. Translate P&IDs, process designs, and engineering packages into installed, commissioned systems in the field.
- Manage day-to-day technical activities on-site: contractor coordination, punch lists, field modifications, and issue resolution.
- Monitor system performance against design intent and flag technical issues clearly and quickly.
- Site Relationships & Coordination Serve as Mantel's day-to-day engineering point of contact with the host site and its technical teams, alongside the Commissioning Director.
- Coordinate with EPC contractors, equipment vendors, and host-site operations staff.
- Maintain a safe, professional, and collaborative site environment at all times.
- Documentation & Reporting Maintain accurate site records: as-builts, field change notices, commissioning logs, and performance data.
- Produce clear, concise site updates and engineering reports for the VP of Engineering and broader project team. Feed lessons learned back into the engineering base for future deployments.
- Performance Monitoring & Feedback Support data collection and system monitoring for technical validation of the demonstration. Surface field observations and operational insights that inform design refinement and scale-up. Work closely with the engineering team to close the loop between design intent and real-world performance.
Who You Are
- Experience: 6+ years in process, mechanical, or chemical engineering with hands-on site or field engineering experience, including at least one commissioning or startup campaign.
- Education: B.Eng. or B.S. in Chemical, Mechanical, or Process Engineering.
- You've been on-site during startup/turnarounds and know what it takes to get a system running.

- You're comfortable working in industrial environments alongside operators, contractors, and plant engineers.
- You think on your feet when things go sideways, and you communicate problems clearly.
- You have genuine curiosity about carbon capture and the role industrial decarbonization plays in reaching net zero.
What You'll Get
- A central role in building one of the most exciting carbon capture companies in the world.
- Meaningful technical contribution from day one, with growing scope as the project portfolio expands.
- Close collaboration with a small, high-caliber engineering and commercial team.
