Associate Director, External Manufacturing

Plant Operations Associate Director, External Manufacturing Office Location: Verona, Wisconsin, United States Home / Careers / Job Openings / Associate Director, External Manufacturing Arrowhead Pharmaceuticals, Inc. (Nasdaq ARWR) is a commercial stage biopharmaceutical company that develops medicines that treat intractable diseases by silencing the genes that cause them. Using a broad portfolio of RNA chemistries and efficient modes of delivery, Arrowhead therapies trigger the RNA interference mechanism to induce rapid, deep, and durable knockdown of target genes. RNA interference, or RNAi, is a mechanism present in living cells that inhibits the expression of a specific gene, thereby affecting the production of a specific protein. Arrowhead’s RNAi-based therapeutics leverage this natural pathway of gene silencing. Arrowhead is focused on developing innovative drugs for diseases with a genetic basis, typically characterized by the overproduction of one or more proteins that are involved with disease. The depth and versatility of our RNAi technologies enables us to potentially address conditions in virtually any therapeutic area and pursue disease targets that are not otherwise addressable by small molecules and biologics. Arrowhead is leading the field in bringing the promise of RNAi to address diseases outside of the liver, and our clinical pipeline includes disease targets in the liver and lung with a promising pipeline of preclinical candidates. Arrowhead’s corporate headquarters is in Pasadena, CA with research and development teams in Madison, WI & San Diego, CA, and a state of the art manufacturing facility in Verona, WI. Our employees are nimble, science-driven innovators who are collaborating to bring new therapies to patients in need. The Position The Associate Director, External Manufacturing will serve as Arrowhead's primary technical and operational owner for a focused portfolio of 1–3 strategic Contract Development and Manufacturing Organizations (CDMOs) supporting the manufacture of siRNA-based therapeutics. This individual will be accountable for end-to-end CDMO relationship management, technology transfer, GMP supply, and lifecycle performance for drug substance (oligonucleotide synthesis and conjugation), targeted delivery components (e.g., GalNAc and other ligand systems), and/or drug product manufacturing operations. Operating as the single point of accountability for assigned CDMO partners, this leader will work seamlessly across Process Development, Analytical Development, Quality, Regulatory, Supply Chain, Program Management, and Clinical Operations to ensure robust, compliant, predictable, and cost-effective supply of clinical and commercial product. The successful candidate is, above all, a highly effective cross-functional leader — someone who builds trust quickly, drives alignment among diverse stakeholders, and converts technical complexity into clear decisions and forward momentum. This role plays a critical part in scaling Arrowhead's platform-enabled RNAi candidates from development through late-stage clinical and commercial readiness, while supporting global regulatory filings and inspection readiness. This position is approved at the Associate Director level. Candidates with significantly greater depth of relevant experience, demonstrated leadership of complex external manufacturing programs, and a track record of successfully managing late-stage or commercial CDMO partnerships may be considered at the Director level. Final leveling will be based on experience and qualifications. This role is based in onsite with an expectation to be in the office five days a week. Responsibilities CDMO Ownership & External Manufacturing Leadership (1–3 Key Partners) Serve as the single point of accountability and primary technical/business interface for an assigned portfolio of 1–3 strategic CDMOs supporting drug substance, conjugation, and/or drug product manufacturing. Own the day-to-day operational relationship: lead joint operating cadences, governance meetings, escalation pathways, and performance reviews; cultivate strong, trust-based partnerships with CDMO leadership and technical teams. Drive on-time, in-full, in-specification delivery of clinical and commercial supply; monitor and report key performance indicators including yield, cycle time, right-first-time, deviation rate, and on-time release. Lead and approve technology transfers from internal Process Development into the assigned CDMO network, ensuring readiness, documentation, and successful demonstration runs. Review and approve batch records, deviations, CAPAs, change controls, investigations, risk assessments, and validation documentation generated at assigned CDMOs. Develop and execute risk mitigation strategies for critical raw materials (phosphoramidites, linkers, solid supports, excipients), secondary sourcing, and capacity contingency. Partner with Procurement and Legal on commercial terms, statements of work, quality agreements, and capacity reservations for assigned CDMOs. Cross-Functional Leadership (Core Competency) Act as the connective tissue between assigned CDMOs and Arrowhead's internal Process Development, Analytical Development, Quality Assurance, Quality Control, Regulatory Affairs, Supply Chain, Program Management, and Clinical Supply functions. Represent External Manufacturing on cross-functional program teams; translate program priorities into clear CDMO deliverables and translate CDMO realities into actionable internal decisions. Lead through influence in a matrixed environment — drive alignment, surface trade-offs, and resolve conflict without relying on direct authority. Facilitate timely, transparent communication across functions and with CDMO partners; ensure stakeholders have the information they need to make sound, fast decisions. Anticipate and remove cross-functional roadblocks; proactively manage handoffs between PD, AD, QA, Regulatory, and Supply Chain to keep manufacturing campaigns on track. Build coalitions around supply strategy, risk decisions, and continuous improvement initiatives; ensure every functional voice is represented and heard. Platform-Based CMC & Technical Oversight Provide technical oversight of solid-phase oligonucleotide synthesis, purification (HPLC, TFF/UF-DF), lyophilization, and associated unit operations at assigned CDMOs. Oversee ligand conjugation processes (e.g., GalNAc) and/or other targeted delivery chemistries executed externally. Support drug product formulation, sterile filtration, fill-finish, and stability programs at assigned partners. Ensure assigned CDMO operations align with platform scalability, comparability, and lifecycle management goals. Maintain rigorous control of critical quality attributes (CQAs), including oligonucleotide purity and impurity profiles (n-1, n+1 species), residual solvents and reagents, conjugation efficiency, potency, and stability. Clinical-to-Commercial Readiness Lead process performance qualification (PPQ), validation, and commercial supply readiness activities at assigned CDMOs. Support comparability assessments for process changes, site transfers, or scale increases. Partner with Supply Chain on demand planning, capacity modeling, and S&OP execution for a growing pipeline. Drive cost-of-goods optimization and continuous improvement initiatives in partnership with assigned CDMOs to support long-term commercial strategy. Regulatory & Quality Interface Contribute to CMC sections for INDs, CTAs, BLAs/NDAs, and global regulatory submissions related to assigned CDMOs and products. Support regulatory agency interactions, pre-approval inspections, and ongoing inspection readiness at assigned external manufacturing sites. Partner with Quality Assurance on quality agreements, audit programs, and remediation planning for assigned CDMOs. Champion a culture of compliance, data integrity, and continuous improvement across the external manufacturing network. Requirements PhD., M.S., or B.S. in Chemistry, Chemical Engineering, Biochemistry, Pharmaceutical Sciences, or related discipline. 8+ years of experience in biopharmaceutical technical operations, external manufacturing, or CMC, with progressive responsibility (less if Ph.D.). Demonstrated success directly managing CDMO relationships as the primary technical/business owner, including technology transfer, GMP manufacturing oversight, and performance management. Direct experience with synthetic oligonucleotide (siRNA or ASO) manufacturing required; experience with GalNAc conjugates or other targeted RNA delivery technologies strongly preferred. Proven ability to lead and influence in a highly matrixed, cross-functional environment spanning PD, AD, Quality, Regulatory, and Supply Chain.
