Sponsorship possible
One solid signal, not two — worth applying, and worth asking about sponsorship early.
- Employer is on a government sponsor recordThe US Department of Labor certified 40 H-1B/E-3 labor condition applications for this employer between Oct 2025 and Jun 2026 (latest Jun 2026) — the step every H-1B hire needs first. USCIS also records 9 H-1B approvals in FY2023. Source: LCA disclosure data (US Department of Labor (OFLC)).
- The posting doesn’t mention sponsorshipSilence isn’t a refusal — ask the recruiter before investing much time.
- No salary bar for this routeH-1B has no fixed salary bar: the employer must pay at least the prevailing wage for the role and area. Cap-subject employers enter a lottery weighted by wage level.

- What Pfizer INC paid sponsored hires in similar roles3 certified filings for “SENIOR SCIENTIST” (Biochemists and Biophysicists) in MA: $128k–$153k, median $132k. Most were filed at wage level III (67%) — 3 lottery entries, ≈46% projected selection odds for cap-subject employers. The pay stated here ($60,200.00 to $100,400.00) is below what this employer usually pays sponsored hires for this role. Source: US Department of Labor LCA disclosure data (Oct 2025 – Jun 2026).

US H-1B: cap-subject employers enter a lottery weighted by wage level — Level I gets 1 entry, Level IV gets 4 (DHS projected selection odds ≈15% at Level I to ≈61% at Level IV). Universities and non-profit research employers are cap-exempt. The $100,000 fee for new petitions from abroad is currently blocked by a court order (appeal pending).

About the role
Use Your Power for Purpose At Pfizer, our purpose is to deliver breakthroughs that change patients’ lives. In this role, you will contribute to the discovery and advancement of innovative medicines for patients worldwide by applying rigorous science, modern pharmacology, and cutting-edge technologies. Your work will help transform promising therapeutic ideas into high-quality experimental data that enable confident decisions across the drug discovery process. What You Will Achieve A key strategic focus within the Internal Medicine Research Unit (IMRU) is the discovery of novel therapies for obesity, cardiovascular disease, and related cardiometabolic conditions. As an Associate Scientist in the In Vitro Pharmacology group, you will contribute to early drug discovery programs by generating rigorous, reproducible pharmacology data that support target validation, assay development, compound profiling, and mechanism-of-action studies. This role is well suited for a collaborative, hands-on scientist with experience in cell-based assay execution, mammalian cell culture, quantitative data analysis, and an interest in receptor pharmacology within cardiometabolic drug discovery. How You Will Achieve It • Develop, optimize, and execute cell-based signaling, ligand-binding, and other in vitro pharmacology assays to generate high-quality data that support project decisions. • Support compound profiling and mechanism-of-action studies through careful experimental design, troubleshooting, and quantitative data analysis. • Maintain mammalian cell cultures and prepare fit-for-purpose cellular or membrane-based assay reagents to support screening, binding, and functional assay workflows. • Apply core pharmacology concepts, including ligand potency, efficacy and affinity to interpret experimental results. • Work collaboratively with pharmacology colleagues and cross-functional project teams to support experimental priorities, data interpretation, and program objectives. • Summarize and communicate experimental findings clearly in team meetings, project discussions, and written updates. • Maintain accurate, timely, and compliant experimental records in an electronic laboratory notebook. Qualifications Must-Have • Bachelor’s degree with any years of laboratory experience. Nice- to-Have • Hands-on experience with mammalian cell culture and cell-based assay execution. • Familiarity with core pharmacology concepts, concentration-response analysis, and principles of robust assay execution. • Experience analyzing and visualizing pharmacology data using Microsoft Excel, GraphPad Prism, or similar tools. • Interest in receptor pharmacology, GPCR signaling, obesity or cardiometabolic drug discovery. • Exposure to compound profiling, screening workflows, assay miniaturization, membrane-based assays, second messenger signaling assays, or emerging technologies to interrogate receptor function is preferred but not required. • Ability to organize, execute, and troubleshoot experiments with attention to detail, scientific rigor, and data quality. • Strong verbal and written communication skills, including the ability to present experimental results in individual and group settings. • Ability to manage multiple priorities and contribute effectively to a collaborative, cross-functional research environment. • Scientific curiosity, enthusiasm for learning, and motivation to contribute to the discovery of new medicines for patients. Work Location Assignment: On Premise The annual base salary for this position ranges from $60,200.00 to $100,400.00.
