Company Description

• Probya is a femtech company building microbiome-focused intimate care products grounded in clinical science. We develop evidence-based formulations designed to work in harmony with the body's natural processes — not against them — addressing the real intimate wellness challenges that antibiotics, hormones, and environmental factors create. We combine microbiology, formulation science, and clinical research to build products that are safe, effective, and honestly positioned.

Role Description This is an ongoing fractional role for a Senior Cosmetic Chemist — not a one-time project. You'll work directly with the founder to lead formulation development and optimization for our intimate care product line, with a strong focus on microbiome compatibility, clinical validation support, and regulatory documentation. This is a hands-on scientific ownership role — you'll review and optimize existing formulations, evaluate raw materials, prepare technical dossiers, and support third-party testing coordination. You won't be managing a team; you'll be a trusted scientific partner to a founder who knows exactly what she's building and needs someone equally rigorous to help build it.

Qualifications

• 3–7+ years of formulation experience in cosmetics, personal care, or intimate wellness, with a track record of stable, safe, consumer-ready formulations
• Applied knowledge of microbiome science in relation to skin or feminine health, including ingredient selection that supports microbial balance
• Experience with preservative system evaluation, stability and compatibility testing, and preparation of formulation dossiers
• Familiarity with cosmetic and OTC regulatory requirements including FDA labeling, MoCRA compliance, and safety substantiation
• Comfortable working directly with a founder in an early-stage environment — you're a clear communicator who can translate complex science into decisions
• Bachelor's or advanced degree in Cosmetic Science, Chemistry, Pharmaceutical Sciences, or related field; intimate care or dermatological product experience strongly preferred
