Working to eradicate or treat bacterial infections such as invasive pneumococcal disease, Group A Strep, and Shigella is just the beginning. Our path to success is clear and well-defined, and Vaxcyte is set up to go the distance. \nWHAT we do is every bit as important as HOW we do it! Our work together is guided by four enduring core values:\n*RETHINK CONVENTION: We bring creative and intellectual diversity to every facet of the work we do in order to innovate and re-innovate the way vaccines are delivered.\n*AIM HIGH: We embody our collectively audacious goal to courageously make the most complex biologics ever attempted to protect humankind.\n*LEAD WITH HEART: Everyone leads at Vaxcyte with a kindness-first, inclusive approach to collaboration and vigorous debate that advances our business objectives.\n*MODEL EXCELLENCE: The magnitude of our challenge requires our shared commitment to demonstrating integrity, accountability, equality and clarity across communications and decision making.\nSummary:\nVaxcyte is seeking an accomplished Director, Immunoassay Development to join the CMC Immunoassay group. This role will provide scientific and strategic leadership for the development, qualification, characterization, governance, and lifecycle management of critical reagents and reference materials that support immunoassays across Vaxcyte's vaccine pipeline.\nA key initial focus of this role will be stewardship of the VAX-31 MSD immunoassay platform, which has been developed and advanced to Phase 3 through extensive internal leadership spanning clinical serology, GLP studies, and immunoassay development. The successful candidate will work in close partnership with current immunoassay leadership to ensure comprehensive knowledge transfer, continuity of scientific and execution excellence, and the long-term robustness of the immunoassay strategy as accountability and responsibility intentionally transition into Analytical Development.\nThis is a hands-on scientific leadership role anchored in CMC execution, GMP readiness, and lifecycle management of immunoassays supporting vaccine development, lot release and stability testing and commercialization.\nEssential Functions:\nHelp establish, lead, and scale the Immunoassay capability within the CMC Immunoassay group, including defining scope, operating model, technical standards, platform strategy, outsourcing approach, validation support model, routine testing model, and control strategy priorities aligned with CMC and program needs.\nProvide daily laboratory leadership, including experimental planning, laboratory schedule coordination, study prioritization, reagent and sample readiness, data review, documentation expectations, instrument and workflow oversight, and hands-on technical support to ensure high-quality execution.\nBuild, mentor, and manage a laboratory-based team of scientists responsible for immunoassay development, optimization, troubleshooting, qualification support, method transfer, validation support, routine analytical testing, lifecycle management, and continuous improvement.\nStrengthen Vaxcyte’s immunoassay portfolio by developing fit-for-purpose immunoassays that support potency, antigenicity, identity, impurity, characterization, comparability, release, stability, and lifecycle needs across the vaccine pipeline.\nProvide hands-on scientific leadership for assay design, sample preparation strategy, reagent strategy, plate or bead format selection, signal detection approach, data analysis model, system suitability expectations, and robustness assessment.\nLead structured immunoassay troubleshooting and root-cause analysis for assay variability, reagent performance, sample preparation, matrix effects, antigen accessibility, signal response, curve behavior, recovery, precision, specificity, robustness, and long-term method trending.\nEvaluate and implement innovative or alternative immunoassay technologies, including ELISA, MSD, automation-enabled workflows, and other relevant ligand-binding assay formats.\nDevelop new immunoassay methods from concept through optimization, qualification readiness, transfer readiness, validation readiness, and lifecycle strategy, including control strategy considerations and documentation suitable for CMC decision-making.\nStrengthen immunoassay analytical control strategies, including critical reagent strategy, reference material strategy, assay controls, system suitability, sample preparation, acceptance criteria, bridging approaches, trending, stability planning, and lifecycle monitoring.\nOversee outsourced immunoassay activities with CROs, CDMOs, contract testing laboratories, reagent vendors, and external technology partners, including technical scope definition, study design review, data review, vendor performance oversight, and deliverable acceptance.\nSupport immunoassay method validation activities in partnership with ASAT, QC, Quality, Regulatory, and external testing partners, including validation strategy, protocol input, acceptance criteria, data interpretation, deviation support, and final report review.\nSupport routine immunoassay testing needs within the CMC Immunoassay group, including development-stage testing, characterization testing, platform evaluation studies, method bridging, comparability support, reagent qualification, and other non-GMP or GMP-supporting analytical activities.\nSupport QC and ASAT teams in technical questions related to release, stability, comparability, PPQ, method transfer, validation readiness, and commercial readiness activities.\nDevelop phase-appropriate immunoassay strategies across the vaccine pipeline, ensuring methods and control strategies are aligned with preclinical, clinical, late-stage, BLA, commercial, and lifecycle needs.\nManage immunoassay development, outsourcing, validation-support, routine testing, and platform innovation activities across multiple projects, including resource planning, timeline management, deliverable tracking, and risk escalation.\nEstablish a high-performing laboratory culture grounded in scientific rigor, accountability, collaboration, transparency, data integrity, hands-on problem solving, operational discipline, and continuous learning.\nContribute to regulatory submissions, health authority responses, technical reports, method development reports, validation strategies, comparability packages, platform evaluation summaries, and BLA-supporting documentation.\nRepresent Immunoassay Development in technical governance forums, program teams, cross-functional reviews, vendor discussions, and external collaborations as needed.\n\nRequirements: \nPhD in Biochemistry, Immunology, Analytical Chemistry, Biological Sciences, or a related field (or equivalent experience) with a minimum of 10 years of experience.
