Polymer Engineer

Company Description

InnerGize is a mental health wearable company focused on revolutionizing mental wellness by combating stress. The company's mission is to help individuals find calm, feel better, and live fuller lives with effective solutions. InnerGize aims to provide everyone with the tools to take control of their well-being.

About the Role

We’re building next-gen hydrogel materials for biomedical and wearable applications. You’ll own formulation, characterization, and scale-up of stimuli-responsive, skin-safe hydrogels—working end-to-end from bench science to pilot manufacturing with QA/RA, product, and clinical teams.

Key Responsibilities

Formulation & Synthesis: Develop PEG/PVA/HA/alginate/chitosan/PNIPAM-based hydrogels; tune swelling, adhesivity, ionic conductivity, and mechanical properties.

Crosslinking Chemistry: Design covalent/ionic/UV/enzymatic systems; optimize gelation kinetics, residual monomer levels, and extractables/leachables.

Characterization: Run rheology, DMA/DSC/TGA, FTIR/NMR, SEM; model WVTR, diffusion coefficients, and drug-release kinetics.

Biocompatibility & Safety: Plan ISO 10993 screens (cytotoxicity, irritation, sensitization, hemocompatibility) with external labs; draft protocols and reports.

Process & Scale-Up: Transfer lab recipes to pilot lines; write batch records/SOPs; execute DoE; drive Cpk/yield improvements; support GMP readiness.

Quality & Documentation: Maintain ELNs, specifications, CoAs, risk assessments; contribute to DHF/DMR and RA submissions.

Cross-Functional Delivery: Partner with design/EE/ME for wearable patch integration (adhesives, electrodes, aging, shelf-life).

Sustaining Engineering: Lead failure analysis (root cause, CAPA) and continuous improvement.

Minimum Qualifications

B.E./B.Tech or M.S./M.Tech in Polymer Science/Materials/Chemical Engg.

3–6 years hands-on hydrogel or soft-polymer formulation experience.

Demonstrated proficiency in rheology and crosslinking chemistry (show 1–2 shipped formulations or pilot runs).

Experience with ISO 10993 planning and report interpretation.

Strong technical writing (SOPs, specifications, validation reports) and DoE/statistics literacy.
