• Operate laboratory equipment including:
• Nanodrop
• pH meters
• Spectrophotometers
• Centrifuges
• Strip readers
• Guillotine
• Isoflow dispenser systems
• Prepare membranes and conjugate pads for assay development and manufacturing support
• Support manufacturing protocols for diagnostic assay production as needed
• Follow all Quality Management System (QMS) requirements and Good Documentation Practices (GDP)
• Maintain a safe laboratory environment, including safe handling of human blood products and laboratory chemicals
• Assist with reagent inventory management, stocking, and ordering
• Support onboarding and training of new team members on lab equipment, SOPs, and documentation practices
• Assist in protocol updates and continuous improvement of laboratory processes

Senior Research Associate Responsibilities

• Independently execute experiments with minimal supervision between project milestones
• Analyze experimental data, draw conclusions, and propose follow-up studies
• Conduct literature reviews and leverage prior project data to guide experimental direction
• Contribute to experimental design discussions and propose well-defined experimental plans
• Communicate technical updates and findings to internal project teams
• Assist with preparation of external reports and scientific presentations
• Draft and refine experimental and manufacturing protocols
• Support onboarding and training of junior laboratory staff
• Assist in troubleshooting experimental challenges and process improvements

Qualifications

Research Associate I

• 1–2 years of laboratory experience (academic or industry)
• Strong attention to detail and ability to follow structured experimental protocols
• Ability to work under close to general supervision with willingness to learn

Research Associate II

• BS or MS degree in a related field
• 2+ years of laboratory or research experience
• Ability to execute experiments under general guidance with defined priorities
• Strong documentation, organization, and communication skills

Senior Research Associate

• BS with 3+ years OR MS with 2+ years of relevant experience
• Strong experience in diagnostic assay development (lateral flow experience preferred/essential)
• Ability to independently execute experiments and interpret data
• Experience contributing to experimental design and scientific decision-making

Required Skills (All Levels)

• Strong written and verbal communication skills
• Excellent attention to detail and documentation practices
• Strong organizational and time management abilities
• Ability to collaborate effectively within a diverse team
• Comfortable working in a fast-paced, regulated R&D environment
• Familiarity with QMS and regulated laboratory workflows

Preferred Qualifications

• Experience in diagnostic assay development, especially lateral flow assays
• Knowledge of ISO 13485 or other regulated quality systems (especially for senior candidates)
• Experience supporting R&D-to-manufacturing workflows
• Exposure to assay scale-up or transfer processes
