The Design Engineer will be an integral part of our Engineering team, contributing to the design and development of biomass-to-biochar conversion technologies, particularly in the realm of pyrolysis technology. This position requires a Mechanical Engineer who is not only adept at learning and applying Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) but also has a keen understanding of value engineering and cost estimation. Acting as a liaison between the Director of Engineering and the product development team, the Design Engineer will play a pivotal role in ensuring innovative, cost-effective, and sustainable solutions for equipment design and scale-up.


Depending on skillset, this individual will co-manage various design, cost estimation, value engineering and cross-functional collaborations pertinent to WasteX including, but not limited to:


Technical Support

  • Collaborate with the Director of Engineering to comprehend project requirements and goals.

  • Utilize engineering principles to enhance the design and optimize biomass-to-biochar conversion systems.

  • Apply value engineering methodologies to identify opportunities for cost savings without compromising quality.


Product Development

  • Work closely with the product development team to translate design concepts into detailed engineering plans.

  • Contribute to the creation of 3D models, drawings, and specifications for components and systems.

  • Incorporate value engineering principles in the design process to achieve optimal performance and cost efficiency.


Cost Estimation

  • Develop accurate cost estimates for materials, labor, and other resources required for project implementation.

  • Collaborate with the procurement team to identify cost-effective suppliers and vendors.

  • Conduct regular cost analyses to track project expenses and identify areas for improvement.


Communication and Coordination

  • Act as a liaison between the Director of Engineering and the product development team to ensure seamless communication.

  • Facilitate meetings and discussions to gather input from various stakeholders, emphasizing cost implications.

  • Collaborate with cross-functional teams to integrate cost-effective design solutions.



  • Maintain detailed documentation of design changes, specifications, and cost estimates.

  • Prepare comprehensive reports and presentations, including cost breakdowns and value engineering analyses.


Continuous Learning and Capacity Building

  • Stay abreast of industry trends, emerging technologies, and best practices in biomass conversion and value engineering.

  • Actively seek opportunities for professional development and training, especially in cost estimation methodologies.


  • Licensed professional engineer (graduated within the last 5 years) preferably with a bachelor’s degree in mechanical engineering.

  • Strong understanding of engineering principles and design fundamentals.

  • Willingness to learn and apply CFD and FEA techniques.

  • Proficiency in 3D modeling software (e.g., SolidWorks, AutoCAD).

  • Excellent communication skills and the ability to work collaboratively in a team environment.

  • Strong problem-solving skills and attention to detail.

  • Willing to pursue advanced learning pathways in Environmental Engineering, Sustainability, or Circular Economy fields.

  • Willing to travel 50% of the time and be deployed on site (locally or around SE Asia) for a minimum of one (1) week per deployment instance.

  • Strong verbal, written, and interpersonal communication skills.

  • Strong project management skills with the ability to manage multiple initiatives simultaneously; excellent time management, analytical, and problem-solving skills; attention to detail; ability to work independently.


  • Monthly salary up to USD 400 - 500 depending on credentials, skills and experience

  • Covered expenses for field trips to farms and locations within the Philippines
