About Tersus Solutions

Founded in 2009, Tersus Solutions is a Denver-based company committed to revolutionizing textile care and circularity with its patented liquid CO₂ technology–the most advanced and environmentally friendly cleaning available.

As the backbone of recommerce™, Tersus partners with leading outdoor, athletic, luxury, and footwear brands to provide full-suite textile reclamation, repair, upcycling, recycling, and logistics solutions. Tersus also sets a new standard in PPE care, utilizing its CO₂ cleaning process to offer unmatched care for firefighter gear, far exceeding the carcinogen removal rate of traditional cleaning methods for safer, more comfortable gear.

Additionally, Tersus reclaims and recycles down from apparel, bedding, and gear, extending the life of valuable materials and reducing waste.

Reporting to our engineering leadership and working cross-functionally with operations and teams across the business, you’ll play a key role in advancing our cleantech. You’ll help evolve our existing machines while also designing new equipment and processes that power textile circularity.

This is a dynamic, hands-on role that blends design and real-world application. This role is a mix of time in front of a computer and getting your hands dirty on the floor. As a senior voice on the team, you'll naturally help shape how we work, share knowledge with those around you, and influence how engineering decisions get made. From day one, you’ll take ownership of meaningful technical challenges, with the opportunity to grow alongside a rapidly scaling team and company.

We’re looking for someone who enjoys solving complex problems, takes pride in thoughtful, high-quality design, and thrives in environments where not everything is fully defined yet. If you’re energized by stepping into the ambiguous, building systems and creating structures, you’ll thrive here.
