About Singletto 

Singletto is building Oxafence, an antimicrobial materials platform designed for real-world infection prevention and military protection. We partner with manufacturers of PPE, uniforms, and other products to translate applied chemistry and microbiology into evidence-backed protective materials. Singletto is a venture-backed Seattle startup focused on scientific rigor, practical product development, and commercialization.

Role Summary

Singletto is seeking an innovative, experienced Textile Research & Development Scientist to develop new antimicrobial textile technologies incorporating Methylene Blue chemistry. 

This is a hands-on R&D role based on-site in Seattle, Washington. You will tackle challenging materials science problems, develop novel formulations and application techniques, and translate promising laboratory discoveries into practical, commercially scalable products. 

We are looking for a creative problem-solver with deep expertise in textile chemistry, chemical finishing, coatings, and wet processing. You will design experiments, explore new approaches, overcome technical barriers, and drive innovation from concept through commercialization. 

The initial focus will be developing durable antimicrobial treatments for military uniforms or medical apparel, addressing challenges including laundering resistance, lightfastness, color stability, and manufacturing scalability. As the program grows, you will help guide and coordinate the work of a small team of chemists and technicians.

What You'll Do 

Research, Innovation & Problem Solving 

• Develop innovative chemical treatments, formulations, and application methods for antimicrobial textiles.

• Explore coating, pigment application, dyeing, and other chemical finishing techniques for polyester, nylon/cotton (NYCO), and other fabrics.

• Solve complex technical challenges involving treatment durability, laundering resistance, lightfastness, color stability, and material compatibility.

• Design experiments, evaluate results, identify root causes of failures, and develop practical solutions.

• Identify promising new materials, technologies, and processes that improve product performance or manufacturability and ensure that the Materials Lab has the necessary equipment and resources to pursue them. 

Product Development & Commercialization 

• Translate laboratory discoveries into reliable, scalable textile treatments and manufacturing processes.

• Develop and refine formulations through laboratory testing, pilot production, and commercial implementation.

• Collaborate with textile mills, chemical suppliers, and manufacturing partners to evaluate and implement new techniques.

• Establish performance specifications, testing methods, and quality control procedures.

• Work closely with Singletto’s microbiologists to connect chemical treatment development with antimicrobial performance. 

Technical Leadership & Documentation 

• Help direct and coordinate the work of a small team of chemists and technicians, providing technical guidance and mentoring.

• Establish experimental priorities, development milestones, and efficient research workflows.

• Maintain rigorous laboratory notebooks, formulation records, and experimental documentation.

• Communicate findings, technical challenges, and recommendations clearly to company leadership.

• Identify opportunities for intellectual property development and protection. 

What We’re Looking For

Must-Haves 

• Degree in Textile Chemistry, Chemistry, Chemical Engineering, Polymer Science, or related fields.

• Significant hands-on R&D experience in textile chemical finishing, coatings, formulation development, or wet processing.

• Demonstrated ability to solve complex technical problems through creative experimentation and scientific analysis.

• Experience developing new chemical treatments, formulations, or manufacturing processes.

• Strong understanding of textile substrates, chemical application methods, and performance testing.

• Ability to translate laboratory research into practical product or process improvements.

• Strong experimental judgment, technical documentation, and communication skills.

• Ability to guide technical colleagues and coordinate collaborative research activities.

• Legally authorized to work in the United States without employer sponsorship.

• Ability to work in-person at Singletto's Materials Lab in Seattle.  

Valuable (But Not Required) 

• Advanced degree in a relevant scientific discipline.

• Experience with pigment coatings, acrylic or polyurethane binders, and functional textile finishes.

• Experience with polyester, cationic dyeable polyester, or NYCO fabrics.

• Background in military, medical, antimicrobial, or protective textiles.

• Familiarity with AATCC, ASTM, or ISO textile testing methods.

• Experience with pilot-scale production, commercial textile finishing, or intellectual property development.

• Experience mentoring or supervising laboratory scientists and technicians. 

Why Join Singletto?

• Develop breakthrough antimicrobial textile technologies with real-world military and medical applications.

• Solve challenging scientific and engineering problems with the freedom to explore innovative approaches.

• Take new ideas from laboratory discovery through commercial implementation.

• Help establish Oxafence™ as a next-generation antimicrobial materials platform.

• Work directly with executive leadership in a fast-moving, high-impact startup.
