Co-founder, Textile Science and Testing

About Lynen

Lynen helps people find out what their clothes are really made of. A clothing label is a claim made by the seller, and it's checked far less often than most people think. In one 2026 EU inspection campaign, 37% of 132 garments weren't made of what the label said (EU JACOP, eight countries, published June 18, 2026).

Lynen buys garments at retail and sends them to independent, ISO/IEC 17025-accredited labs. Then it shows the lab's result next to the label's claim: what the fabric is made of, a chemical screening for substances like formaldehyde, PFAS and nickel, and how the fabric holds up to washing and wear.

The Lynen app is built for iPhone and Android and is in testing now. Our website, lynenlabs.com, publishes our research and our testing method in six languages. We're pre-launch, small, and serious about getting the science right.

Why this role exists

Lynen was founded by Chinedu Okeke. The app, the website and the brand are built. What Lynen needs next is a co-founder who knows textiles from the inside: how fibers behave, how fabrics are tested, and how to read a lab report and know when it means something.

You'd own the science behind every result Lynen publishes.

What you'll do

• Shape how Lynen tests garments: which methods we commission (for example, ISO 1833 for fiber content), what counts as a real discrepancy, and how normal manufacturing tolerances are handled.
• Review lab reports before a result goes live, and help decide when a second test is needed.
• Help choose accredited labs and build those relationships.
• Help set the rules behind our wear ratings, such as color after washing and pilling.
• Check our fiber guides and articles for technical accuracy.
• Help plan Lynen's longer-term goal of running a lab of its own.
• Bring a fashion lens: how garments are designed, made and sold, and what shoppers actually care about.

Who you are

• You hold an undergraduate or graduate degree in textile engineering, textile science, fiber science, materials science, apparel engineering, or a related field.
• You care about fashion and how clothes are made.
• You're passionate about what Lynen is building. You believe people deserve to know what they're buying, and you want to help build the thing that tells them.
• You're comfortable working remotely, on your own schedule.

Nice to have

• Hands-on lab experience with textile test methods (ISO, AATCC or ASTM).
• Familiarity with ISO/IEC 17025 and how accredited labs work.
• Knowledge of textile labeling rules, such as the FTC Textile Act or EU Regulation 1007/2011, or chemical limits such as EU REACH.
• Experience in sourcing, manufacturing or quality control.
• You like explaining technical ideas in plain words.

The commitment

• Part time. There are no set hours, and no full-time commitment is expected.
• This role is unpaid. Equity is to be discussed with the right person.
• Remote, with flexible check-ins.

What you get

• A co-founder's say in how Lynen checks clothing, from the first published result onward.
• The chance to build something useful for shoppers who are tired of guessing.

How to apply

Apply here on Wellfound with your resume or LinkedIn profile and a short note. A few sentences is fine. Please answer two questions:

1. Why Lynen?
2. Tell us about a garment whose label you didn't believe, and why.
