Are you passionate about the sustainability agenda? Do you want to be part of an international project? Do you thrive with responsibility and development? If you can recognize these statements, you might want to consider joining our team at Biomason! We are looking for a Senior Mechanical Engineer to join our international project based in Ikast, Denmark. Biomason is decarbonizing the built environment through planet-friendly, high-performance biocement. As a global leader in bio-concrete, we are tackling carbon emissions at their source by rethinking how cement is made. Instead of relying on traditional carbon-intensive processes, we harness the natural power of microorganisms to grow our biocement, delivering a high-quality material with a significantly lower environmental footprint. As Senior Mechanical Engineer, you will play a hands-on leadership role in establishing, stabilizing, and improving the mechanical performance of our first-of-a-kind tile production facility in Ikast. This role is part of our evolving operations leadership team and will work closely with Operations, Maintenance, Quality, and Process Engineering to ensure safe, reliable, and efficient plant performance. You will first help translate innovative process science into robust day-to-day manufacturing at the first of a kind facility, while driving structured problem-solving, equipment reliability work, plant expansion support, and continuous improvement across the facility. You will then support the scaling of this process to our first commercial facility from engineering design and equipment selection through commissioning, start-up, and operations.
Job Responsibility:
Provide day-to-day supervisory and execution support for mechanical systems and production equipment across the tile manufacturing process
Lead troubleshooting and root cause analysis for mechanical failures, downtime events, and recurring equipment issues
Help establish preventive and predictive maintenance routines for critical equipment, utilities, and production assets
Support commissioning, start-up, and scale-up activities in a FOAK environment, helping to translate development work into reliable plant operation
Partner with Operations and Quality teams to improve equipment performance, uptime, process stability, and product consistency
Drive structured continuous improvement initiatives using data, operator feedback, and practical floor-based observations
Promote and embed 5S, good manufacturing practices, and disciplined ways of working throughout the production area
Contribute to waste reduction, line efficiency, and standardization efforts as production scales
With the Director of Projects and an EPC firm, act as Biomason’s lead Mechanical Engineer supporting the development of FEL3 and Detailed Engineering design packages including participation in and review of Block Flow Diagrams (BFDs), Heat and Material Balances (HMBs), Piping and Instrumentation Diagrams (P&IDs), General Arrangements (GAs), Basis of Design (BoD) documents, equipment specification and selection, and HAZOP
Support the commissioning and startup of the commercial facility through participation in Factory Acceptance Testing (FAT) at vendor sites as needed and Site Acceptance Testing (SAT) at the facility
Provide on-site technical leadership during the "boots-on-the-ground" commissioning phase, troubleshooting mechanical, thermal, or other deviations in real-time
Bridge the gap between EPC firms and internal operations to ensure a seamless handover
Support the development of SOPs, technical work instructions, equipment care standards, and troubleshooting guides
Coordinate with vendors, contractors, and internal teams on equipment modifications, installation work, and performance improvements
Serve as a visible, hands-on member of the leadership team and help build a strong safety and performance culture on site
Requirements:
Minimum 10 years of experience in mechanical engineering, maintenance engineering, plant leadership, or a similar industrial role
Strong experience in industrial process or manufacturing environments, ideally with automated or semi-automated production equipment
Experience supporting production start-ups, greenfield projects, FOAK environments, or first-time industrial implementation is strongly preferred
Strong understanding of industrial mechanical systems, equipment reliability, maintenance strategies, and structured troubleshooting
Experience with 5S, good manufacturing practices, and continuous improvement in a production setting
Ability to read technical drawings, manuals, equipment layouts, P&IDs, and supplier documentation
Hands-on leadership style with the ability to balance technical depth and operational urgency
High attention to detail, with the ability to manage complex, detail-oriented projects and ensure disciplined follow-up through execution
Strong organizational and communication skills, with the ability to work across functions and cultures
Structured, practical, and data-informed approach to problem-solving and decision-making
Ability to help build stable and scalable ways of working in a growing manufacturing environment
Focus on safety, reliability, efficiency, and sustainable long-term plant performance
Proactive, practical, and motivated by solving real industrial challenges
Thrive in a hands-on environment where systems and routines are still being built
Fluency in English is essential
Motivation should stem from contributing to an organization that prioritizes sustainability and innovation within the cement industry
Nice to have:
Familiarity with Six Sigma, Lean manufacturing principles, root cause analysis methodologies, and continuous improvement practices is an advantage
What we offer:
Competitive salary and comparable benefits
Part of a team with colleagues based in Ikast, Denmark and a larger team based in the US
Part of an innovative team with different cultural backgrounds
Culture of entrepreneurship, creativity, and future focused strategies
Unique opportunity to make a difference and build a sustainable future
