Mantel is developing the first molten-salt-based carbon capture technology which is 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.

Site Relationships &amp; Coordination<ul><li>Serve as Mantel's day-to-day engineering point of contact with the host site and its technical teams, alongside the Commissioning Director</li><li>Coordinate with EPC contractors, equipment vendors, and host-site operations staff</li><li>Maintain a safe, professional, and collaborative site environment at all times</li></ul>4. Documentation &amp; Reporting<ul><li>Maintain accurate site records: as-builts, field change notices, commissioning logs, and performance data</li><li>Produce clear, concise site updates and engineering reports for the VP of Engineering and broader project team</li><li>Feed lessons learned back into the engineering base for future deployments</li></ul>5. Performance Monitoring &amp; Feedback<ul><li>Support data collection and system monitoring for technical validation of the demonstration</li><li>Surface field observations and operational insights that inform design refinement and scale-up</li><li>Work closely with the engineering team to close the loop between design intent and real-world performance</li></ul>Who You Are:<ul><li>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</li><li>Education: B.Eng. or B.S. in Chemical, Mechanical, or Process Engineering</li><li>Legal to work in either the United States or Canada</li></ul>Put differently,<ul><li>You've been on-site during startup/turnarounds and know what it takes to get a system running - you don't need someone to walk you through it</li><li>You read drawings, write procedures, and close punch lists - your documentation is clean and complete</li><li>You're comfortable working in industrial environments alongside operators, contractors, and plant engineers</li><li>You think on your feet when things go sideways, and you communicate problems clearly</li><li>You have genuine curiosity about carbon capture and the role industrial decarbonization plays in reaching net zero</li></ul>What You'll Get: 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·        A clear path toward senior engineering leadership as Mantel scalesWe provide competitive and holistic compensation to all our full-time team members, including:·        Highly competitive pay based on experience, including equity·        90% subsidized medical and dental healthcare coverage for employees, 50% for dependents·        Unlimited vacation policy, mental health personal days, generous sick leave, plus a week-long winter break at the end of December·        Health/Fitness and cell phone stipend·        Paid parental leave

Mantel is developing the first molten-salt based carbon capture technology. Our molten borates are designed to operate at the high temperatures found inside boilers, kilns, and furnaces &ndash; enabling highly efficient carbon capture that has not been possible until now. Carbon capture can be applied across industry to reduce emissions - and even achieve net-negative emissions. By solving for efficiency Mantel can reduce energy losses by more than 60% and cut costs in half, unlocking carbon capture&rsquo;s role in reaching global net zero.
