R&D Polymer Chemist

Location: Marlborough, MA Business: Interconnect Solutions (ICS) – Advanced Circuit & Packaging (ACP)

Overview: We are seeking an experienced Polymer and Synthetic Chemist with deep expertise in polymer synthesis and organic synthesis to create new molecular and polymer platforms in advanced semiconductor packaging. The ideal candidate combines hands‑on synthetic chemistry with an understanding of product application requirements, and understands structure-function relationships to deliver tailored materials for thermal, electrical, interfacial and mechanical performance. Experience with lithography and adhesives is preferred.

Key Responsibilities: Technical Leadership Design and executepolymer synthesis(e.g., step‑growth, free‑radical/controlled radical such as RAFT/ATRP, thermoset B-staging) andorganic synthesisof monomers, oligomers, and functional small molecules for high‑purity, semiconductor‑grade applications. Authortechnical reports and patents, with strong communication and documentation and firm understanding of patent strategy and criteria. Assessscientific literature, patent landscapes, prior art, and competitive approachesto guide research direction and support freedom‑to‑operate and IP decisions. Applystatistical reasoning, such as how to apply confidence intervals, hypothesis testing and how residuals affect models to draw strong conclusions through experimental rigor, familiarity with statistics software is preferred. Build and qualifyanalyticsfor polymers and small molecules (GPC/SEC, NMR, 2D NMR, LC/MS or MALDI, HPLC/UPLC, FT‑IR, DSC/TGA, rheology, residual solvents/ions, metals) and deliver deep structural insights to correlate with product performance. IncorporateEHSand process safety (thermal hazard screening, CHETAH/DSC/ARC as applicable) into scale‑up; participate inPHA(process hazard analysis).(Preferred) Applyformulation principlesto synthesized materials design with respect to lithography and adhesives. Develop understanding of formulation templates and key concepts that inform accelerated recursive development of materials. Project & Cross‑Functional Leadership Collaborate across Qnity to develop strongcross functional relationshipsof different materials toolboxes available and Qnity’s unique material portfolio. Collaborate acrossR&D, Applications, Manufacturing, Product Management, Quality, and Supply Chainto align transfer of new materials to scale up and products. Coordinate with global teammates across Americas/EMEA/APAC time zones; plan/attend meetings outside local business hours when necessary. Mentor junior scientists/engineers in synthetic methods, data analysis, documentation rigor, and good manufacturing practices.

Qualifications: Required Ph. D.in Polymer Science/Engineering, Organic Chemistry, Materials Science, or closely related field;3+ yearsindustrial experience inpolymer and/or organic synthesis. Demonstrated successtailoring material platformsfor product performance and customer requirements, especially with respect to lithography and adhesives. Track record ofcreative and innovative thinking, developing and introducing new materials and methods into relevant applications through testable hypotheses and experimental plans while generating clear conclusions and next steps. Track record ofIP generation(patents, trade secrets) and/or external publications. Proficiency with corepolymer/chemical analytics(GPC, NMR, 2D NMR, LC/MS or MALDI, HPLC, FT‑IR).Hands‑on experience developingisolation and purification strategiesfor polymers, monomers, or specialty chemicals, with attention to residual monomers, solvents, catalysts, metals, ions, and particles. Proven track record executing projects through Stage‑Gateor Phase‑Gate frameworks. Excellent documentation and communication skills; ability to present complex data to technical and business stakeholders. Flexibility to collaborate with a global team across time zones, including occasional early‑morning or evening meetings. Ability to travel domestically/internationally (U.S. Citizen or Green Card holder. Preferred Hands‑onlithographyexperience (e.g., coating films, exposure tools development process, some metrology) applied to functional polymers. Hands‑onstructural adhesiveexperience, such as formulation, coating (spin coating and slot die coating), curing and associated outputs such as die shear, stud pull testing, cross hatch tape peel testing, 90 degree peel testing, or dual cantilever beam fracture mechanics. Hands‑onpolymer thermal analysisexperience, including DSC, TGA, TMA, DMA, Rheology. Experience insemiconductor‑gradechemical production, contamination control, and quality systems (e.g., metals/ionic cleanliness, particle control, trace analytics).Strong skills in DoE, SPC, statistical analysis (JMP/Minitab) and data‑driven decision making. Experience withair‑sensitive, moisture‑sensitive, light‑sensitive, or controlled‑addition reactions, including inert‑atmosphere techniques. People leadership or mentoring experience in a fast‑paced, cross‑functional setting.
