About Dermaweave
DermaWeave is a world-first contactless microfibrous delivery system for use following cosmetic procedures. Developed by Corryn Biotechnologies, the platform uses a patented handheld applicator and single-use fluid cartridge to form a breathable, soluble microfibre matrix directly onto the skin, delivering soothing coverage and consistent cosmeceutical release. We are a lean, fast-moving startup currently in regulatory and clinical testing phases, with a commercial launch targeted for summer 2026.
Job Summary
We are hiring a Senior Formulation Scientist to take full ownership of the DermaWeave active-eluting formulation from now through to commercial launch and beyond.
This is a hands-on, autonomous role. You will lead all formulation development and stability testing, produce documentation to UK, EU and US regulatory agencies, and work directly with founders, clinical partners, and aesthetic practitioners. You will be expected to make decisions, drive progress, and own outcomes.
This role is not for someone who needs an established team or a well-trodden path. It is for a self-starter who thrives in ambiguity and takes genuine pride in scientific rigour.
Essential Responsibilities
⬢ Lead formulation development for DermaWeave's fluid cartridge system.
⬢ Drive formulation activities through the current regulatory and clinical testing phase.
⬢ Select and substantiate active ingredients (ceramides, barrier-repair lipids, calming agents, humectants) appropriate for skin care products.
⬢ Design, execute, and interpret stability protocols (real-time, accelerated, photo-stability) and preservation efficacy testing.
⬢ Produce and maintain rigorous technical documentation — formulation records, SOPs, batch manufacturing instructions, safety dossiers — to standard required for UK, EU and US regulatory compliance.
⬢ Collaborate with cross-functional teams including clinical partners and aesthetic practitioners to align formulation performance with real-world post-procedure outcomes.
⬢ Mentor junior team members and contribute to a collaborative R&D environment.
⬢ Support intellectual property activities and assist in patent applications related to innovations.
⬢ Provide formulation input to safety assessments and CPSR.
Essential experience and qualifications
⬢ A bachelor’s degree or higher in Cosmetic Science, Pharmaceutical Sciences, Chemistry, Biochemistry, or a closely related field.
⬢ 7 years of experience in cosmetic formulation with a clear focus on skincare.
⬢ Demonstrated formulation experience with sensitive, compromised, or barrier-disrupted skin — chemical peels, laser, microneedling, or equivalent post-procedure contexts.
⬢ Proficiency in emulsion technology, gel systems, anhydrous and fluid formulations, and encapsulation platforms.
⬢ Strong working knowledge of skin barrier biology: stratum corneum structure, wound-healing cascade, TEWL dynamics, and transdermal delivery mechanisms.
⬢ Functional knowledge of UK Cosmetic Regulation, EU Cosmetic Regulation 1223/2009, and MoCRA for US market entry.
⬢ Practical understanding of ISO 22716 — batch records, traceability, deviation management, and documentation standards consistent with a product under regulatory review.
⬢ Proven ability to work independently, manage your own priorities, and deliver in environments where structure is still being built.
⬢ Robust communication skills for both technical and non-technical audiences.
Desirable experience
⬢ Experience working with novel or device-adjacent delivery formats (encapsulated actives, microfibre matrices, electrospun systems, or comparable).
⬢ Experience collaborating directly with dermatologists, aesthetic practitioners, or clinical teams to align formulation design with treatment outcomes.
⬢ Previous experience in a startup, early-stage company, or standalone R&D function where autonomy and breadth were required.
We offer
⬢ A salary of £45,000–£60,000 depending on experience, plus stock options package.
⬢ Scientific ownership, you will be the lead formulation voice on a world-first, patented platform.
⬢ A role that will develop your expertise in device-adjacent cosmeceutical delivery.
⬢ Direct access to founders and decision-makers.
⬢ Flexible working arrangements around core lab hours, and a genuine commitment to your professional development as the company scales.
