About The Position

The Lumber Manufactory (TLM) is building the future of sustainable lumber with next-generation sawmill technology. We design and operate state-of-the-art modular sawmills that produce high-grade dimensional wood products with greater efficiency and less waste. Backed by leading investors including Cantos, Slow Ventures, Susa Ventures, Banter Capital, Humba Ventures, and Ravelin Capital.
The Lumber Manufactory (TLM) is seeking a Principal Engineer to drive engineering rigor and operational excellence across deployment and production initiatives. This role will be responsible for establishing quality standards, processes, and documentation that enable a seamless transition from R&D to full-scale production.
As a Technical Chief of Staff, you will bring structure, clarity, and technical insight to fast-moving engineering teams building and deploying mills across the Southeast US. You will work closely with senior leadership and engineering teams to define roadmaps, implement best practices, and drive technical excellence. This role requires strong ownership, strategic thinking, and the ability to solve complex technical challenges while aligning stakeholders around shared goals.

The ideal candidate is a systems builder with experience turning complex technology into repeatable, automated deployments — especially in rural or remote environments where infrastructure is sparse, support is limited, and designs must be rugged, reliable, and self-sufficient.

Requirements

• 10+ years of experience in engineering leadership roles with a strong focus on operational excellence and process development.
• Proven track record of building technical roadmaps and building processes.
• Strong analytical and problem-solving skills with the ability to provide strategic insights to senior leadership.
• Exceptional communication and stakeholder management skills.
• Experience in high-growth or complex technical environments preferred.

Responsibilities

• Define and implement engineering quality standards and best practices across design, systems, manufacturing, and industrial engineering disciplines.
• Develop and maintain documentation frameworks to ensure consistency and compliance.
• Build and optimize processes that enable smooth transitions from R&D to production environments.
• Establish metrics and governance models to monitor engineering performance and quality.
• Act as a trusted technical advisor to the VP of Deployment and Operations, providing insights on engineering strategy, resource allocation, and risk management.
• Gather feedback and ideas from engineering teams and translate them into actionable strategies.
• Collaborate with cross-functional teams to create technical roadmaps aligned with business objectives and operational goals.
• Ensure roadmap execution supports scalability, reliability, and efficiency.
• Champion a culture of rigor, excellence, and continuous improvement within engineering teams.
• Facilitate communication between leadership and technical teams to ensure alignment and transparency.

Benefits

• 100% employer-paid health coverage for employees and dependents (medical, dental, and vision)
• 100% employer-paid life insurance and disability coverage
• Paid time off and company holidays
• The opportunity to help build something from the ground up in an essential, evolving industry
