The impact you will make:
Agios is seeking a talented and highly motivated Senior Scientist to join the Chemical Development & Manufacturing (CDM) team. This is a bench-forward, technically deep role for a scientist who thrives in the laboratory and wants to build expertise across the full spectrum of small molecule drug substance development — from early process design through technology transfer and clinical manufacturing.
Reporting to and closely supporting a CDM SME, you will serve as a key scientific contributor on an assigned small molecule program. Your primary responsibility is hands-on laboratory execution: generating the experimental data that drives process understanding, informs solid-state decisions, demonstrates scale-up feasibility, and enables the team to advance with confidence through each stage of development. You will be the bench anchoring the program.
What you will do:
Process Chemistry — Bench to External Scaleup
-
Design, execute, and interpret laboratory experiments to develop robust, scalable synthetic routes for small molecule drug substances; apply mechanistic understanding to guide reaction optimization and troubleshooting.
-
Conduct structured process optimization studies (including DOE-driven parameter screening and Design Space mapping) to define critical process parameters and establish proven acceptable ranges.
-
Generate high-quality impurity profiles; identify, synthesize, and characterize process-related impurities; develop and implement control strategies to meet ICH Q3A/Q3C requirements.
-
Document and transfer to external CDMOs kilo-lab and pilot-scale reactions under GMP or GMP-like conditions; evaluate equipment performance, mixing dynamics, heat transfer behavior, and process scalability with increasing batch sizes.
-
Investigate and resolve process-related manufacturing deviations, atypical results, and OOS observations through systematic root cause analysis and corrective action experiments at the bench.
-
Explore and apply advanced synthetic technologies to accelerate development — including continuous flow chemistry, in-line process analytics (PAT), and computational tools for reaction and process modeling.
Solid State Development & Crystallization Science
-
Conduct polymorph, salt, co-crystal, and solvate screening campaigns to identify and evaluate drug substance solid forms with appropriate physical, chemical, and stability properties for development.
-
Design and execute crystallization development studies — including solvent system evaluation, antisolvent addition, seeding strategies, and cooling profiles — to deliver a controlled, reproducible, and scalable crystallization process.
-
Characterize solid forms using standard analytical techniques (XRPD, DSC, TGA, PLM, dynamic vapor sorption, NMR) and interpret data in the context of form selection and process design.
-
Develop particle engineering strategies to achieve target particle size distribution, morphology, and bulk density requirements critical for downstream processing and formulation compatibility.
-
Assess solid form stability under stressed and ICH-aligned conditions; support selection of the preferred commercial form through integrated analysis of processability, stability, and bioavailability data.
-
Maintain and transfer crystallization processes to CDMO partners in collaboration with the AD; provide technical input during scale-up and troubleshoot crystallization-related issues observed at manufacturing scale.
Engineering Support & Scale-Up Execution
-
Support technology transfer of laboratory processes to CDMOs and CROs by preparing detailed process descriptions, batch manufacturing records, and engineering run protocols in collaboration with the AD program lead.
-
Support the evaluation of production-scale equipment relevant to drug substance manufacture — including stirred tank reactors, agitation systems, filtration equipment, and drying technologies — providing bench-scale data to inform equipment selection and process fit.
-
Participate in and provide scientific support for engineering runs and cGMP manufacturing campaigns at CDMO sites; assist in the assessment of process performance against development data and identify opportunities for process improvement.
-
Apply process safety principles in laboratory and kilo-lab work; conduct reaction hazard assessments (e.g., DSC-based calorimetry, gas generation) and incorporate findings into scale-up risk evaluations.
-
Contribute to the development of process control strategies, in-process testing specifications, and acceptance criteria aligned with quality-by-design (QbD) principles and ICH Q8/Q11 guidance.
Data Management, Documentation & Regulatory Support
-
Maintain thorough, contemporaneous electronic laboratory notebooks (ELN) and generate well-organized experimental reports that accurately capture methods, data, observations, and scientific conclusions.
-
Contribute to the authorship of development reports, process descriptions, technology transfer packages, and CMC regulatory sections (IND, CTA, QOS, NDA Module 3 / MAA Module 3) under the direction of the CDM SME.
-
Present experimental results and scientific interpretations to the CDM team, cross-functional CMC sub-teams, and external partners in a clear, organized, and data-driven manner.
What you bring:
-
Ph.D. in Organic Chemistry, Chemical Engineering, or a closely related discipline with 2–6+ years of pharmaceutical industry experience; or M.S. with 5–10+ years, with demonstrated laboratory leadership and increasing technical scope.
-
Substantial hands-on synthetic organic chemistry experience at laboratory and, ideally, kilo-lab or production scale; proficiency in a broad range of reaction classes, purification methods, and analytical characterization techniques.
-
Demonstrated experience in process chemistry — including reaction optimization, impurity identification and control, and scale-up evaluation — applied within a pharmaceutical development context.
-
Familiarity with cGMP principles, ICH guidelines (Q3A/C, Q6A, Q8, Q11), and the documentation standards applicable to small molecule drug substance development.
-
Strong laboratory technique, attention to detail, and a disciplined approach to experimental design, data interpretation, and scientific record-keeping.
-
Effective written and verbal communication skills; ability to present complex experimental results clearly and concisely to colleagues, cross-functional partners, and external collaborators.
-
Ability to work productively in a collaborative, fast-paced, matrixed environment with competing priorities and evolving program needs.
Preferred Qualifications
-
Hands-on experience with structured DOE methodologies (e.g., JMP, Design-Expert) applied to process characterization, parameter ranging, or crystallization optimization.
-
Practical experience with PAT tools (in-line Raman, IR, FBRM, PVM) in laboratory or scale-up settings, and familiarity with their application in process monitoring and control.
-
Demonstrated kilo-lab or pilot-scale reactor experience, including familiarity with agitation, heat/mass transfer considerations, and scale-dependent process behaviors.
-
Prior involvement in technology transfer campaigns to CMOs/CDMOs, including preparation of process descriptions, batch record templates, or engineering run protocols.
-
Experience contributing to regulatory CMC documents (IND, CTA, Module 3 QOS sections) or development reports reviewed by regulatory agencies.
-
Working knowledge of solid-state chemistry principles and practical experience with crystallization development, polymorph screening, or solid form characterization relevant to drug substance manufacture.
-
Knowledge of process safety evaluation techniques (DSC calorimetry, ARC, reaction gas generation studies) applicable to pharmaceutical manufacturing scale-up.
-
Experience with solid-state analytical techniques: XRPD, DSC/TGA, dynamic vapor sorption, PLM, or solid-state NMR for solid form characterization and stability assessment
