" **Job Description** About the Role As Delivery Manager – API, you will lead the full spectrum of drug development, overseeing the design, development, scale\-up, and approval of APIs including complex molecules like peptides, Oligonucleotides and ADC. This role demands deep expertise in Upstream viz. Solid\-phase, Liquid and hybrid peptide synthesis and downstream viz. purification and isolation techniques viz. Lyophilization, spray drying, Characterization, and regulatory aspects. You will collaborate cross\-functionally to deliver IP\-driven, globally compliant, and commercially viable peptide products — accelerating development timelines while ensuring safety, scalability, and sustainability. Role expectations: * API Process Development: Drive the design and optimization of peptide synthesis (SPPS, LPPS, hybrid), conjugation chemistry, Oligonucleotide synthesis, ADCs and downstream purification (HPLC, Ultrafiltration, lyophilization). * Early\-to\-Late\-stage Development: Lead the molecule’s journey from preclinical stage through clinical scale\-up to tech transfer and commercial manufacturing. * Quality by Design (QbD): Implement QbD principles, risk assessments, and DoE strategies to build robust, reproducible processes. * CMC Strategy \& Regulatory Alignment: Provide strategic input and documentation for DMF, and ANDA submissions in major regulatory markets (US, EU, ROW). * Analytical Support: Collaborate with analytical development teams to establish validated, peptide\-specific analytical methods (purity, identity, aggregation, and stability). * Scale\-up and Technology Transfer: Drive the scale up of the designed process by deploying suitable technology and guide the CFTs for seamless execution * Peptide\-Specific Challenges: Tackle technical complexities like peptide solubility, aggregation, stereoisomerism, sequence\-specific stability, and scale\-up of long\-chain peptides or cyclic analogues. * Technology Scouting \& Innovation: Identify and deploy emerging peptide technologies (microwave\-assisted SPPS, flow synthesis, peptide–drug conjugates). * Lifecycle \& Cost Management: Optimize synthetic routes for cost, purity, and process yield across the lifecycle. **Qualifications*** PhD in Organic/Medicinal Chemistry, Peptide Chemistry, or related field * 15\+ years of experience in API development, with significant focus on peptides, Oligonucleotide and ADC development * Proven expertise in solid\-phase synthesis, downstream processing, analytical method development, and scale\-up * Familiarity with GMP manufacturing, global regulatory guidelines (ICH, USFDA, EMA), and CMC dossier preparation * Demonstrated leadership in cross\-functional environments, tech transfer, and regulatory interactions **Additional Information** About the Department \- IPDO At the core of our R\&D prowess is the Integrated Product Development Organisation (IPDO) at Bachupally, Hyderabad, India.
