Experience with capillary electrophoresis (CE) and/or imaged capillary isoelectric focusing (icIEF) is a plus.

• Perform routine analytical testing using HPLC/UHPLC platforms (sample and reagent preparation, instrument operation, maintenance, basic troubleshooting, and UV/Vis and fluorescence detection).
• Perform and support a range of chromatographic methods (reversed-phase HPLC/UHPLC, SEC, SAX, and SCX) for characterization of oligonucleotides and other complex biomolecules.
• Experience with capillary electrophoresis (CE) and/or icIEF is a plus.
• Support analytical method development and optimization (method execution, troubleshooting, data review and interpretation, and communication of results to scientific teams).
• Maintain accurate experimental records and analytical documentation

• Manage laboratory inventory, including chemicals, reagents, columns, standards, consumables, PPE, and general supplies; monitor stock levels, expiration dates, and storage requirements and reorder as needed.
• Coordinate laboratory equipment installation, preventive maintenance, calibration, repair, and vendor service, while maintaining equipment records and service documentation.
• Support day-to-day shipping and receiving of laboratory materials, samples, reagents, and equipment, including shipment verification, tracking, packaging, courier coordination, and temperature-controlled or dry-ice shipments.
• Partner with Facilities, EHS, IT, Procurement, and external vendors to support laboratory infrastructure, safety, repairs, equipment moves, installations, and workspace changes.
• Identify and elevate operational or facilities issues that could affect laboratory activities and coordinate timely resolution with internal teams and service providers.

• Bachelor's degree in Chemistry, Biochemistry, Analytical Chemistry, Pharmaceutical Sciences, Chemical Engineering, or a related scientific discipline, with approximately 1-3 years of relevant laboratory experience in biotechnology, pharmaceutical, life sciences, or a related environment.
• Demonstrated hands-on experience with HPLC and/or UHPLC (sample preparation, instrument operation, data acquisition and analysis, basic troubleshooting, and detection methods including UV, fluorescence, CAD, RI, and/or MALS), with familiarity with additional chromatography techniques (SEC, SAX, and/or SCX).
• Strong understanding of analytical instrumentation and laboratory workflows, including the ability to operate and troubleshoot laboratory equipment while supporting day-to-day laboratory operations (inventory management, shipping and receiving, equipment coordination, supplies, and laboratory organization).
• Strong organizational, communication, and documentation skills, with excellent attention to detail, ownership, and follow-through; ability to manage multiple priorities and balance scientific responsibilities with operational needs in a fast-paced research environment.
• Demonstrated ability to work independently and collaboratively across cross-functional teams, including scientists, Facilities, EHS, Procurement, external vendors, and shipping providers, with a proactive and service-oriented approach to laboratory readiness and operational support.
• Ability to build alignment, foster collaboration, and drive shared ownership across functions to achieve results in a complex, matrixed environment.
• Ability to travel to Avidity's San Diego headquarters approximately twice per year for company development weeks and occasional in-person collaboration.
• Demonstrated curiosity and openness to integrating AI-powered tools to enhance functional processes, support data-informed decisions, and drive innovative outcomes across teams.

• The base salary range for this role is $43.50-$48.50/hr. The final compensation will be commensurate with such factors as relevant experience, skillset, internal equity and market factors.
