Job Summary

Role Summary

The Process Engineer – PAT will lead and support the design, deployment, and lifecycle management of PAT solutions across peptide, oligonucleotide, and small-molecule drug product manufacturing platforms, with a special focus on organic synthesis, crystallization, and formulation operations. The role bridges process science, advanced analytics, and digital control systems to enable real-time process understanding and predictive control in alignment with Quality by Design (QbD), ICH Q8–Q14, and digital twin frameworks.

Key Responsibilities

1. PAT Strategy & Implementation

• Identify and implement suitable PAT tools end to end in the R&D developmental workflow (Drug substance to Drug product) and transfer critical PAT tools to the manufacturing plant at a commercial scale.

• Develop calibration and chemometric models (PLS, PCA, ANN) for real-time release or feedback control.

• Collaborate with the automation team to integrate PAT tools with automation platforms (DeltaV, Siemens PCS7, SynTQ, SIPAT, Seeq) for model-based control.

2. Process Understanding & Scale up

• Collaborate with process engineers/scientists, support development of process models for synthesis, crystallization, and formulation and enable robust scale-up.

• Use PAT data for DoE-based optimization, multivariate analysis (MVDA), and robustness assessment.

• Support continuous-manufacturing and intensification initiatives through inline analytics.

3. Data Analytics & Systems Integration

• Develop data pipelines linking PAT instruments with historians, MES, and data-lakes.

• Apply advanced analytics (Python, MATLAB, SIMCA, Unscrambler, JMP) for trend prediction and fault detection.

• Collaborate with data-science teams for AI/ML model development for yield, impurity, and polymorph prediction.

4. Compliance & Lifecycle Management

• Ensure regulatory alignment with ICH Q8–Q11, FDA/EMA PAT frameworks.

• Prepare validation protocols, SOPs, and regulatory documentation for PAT method qualification.

• Manage change control, deviation, and audit responses related to PAT systems.

5. Cross-Functional Collaboration

• Partner with R&D, MSAT, Automation, QA/QC, and Manufacturing for PAT-enabled process transfers.

• Support tech transfer, scale-up, and troubleshooting of operations.

• Collaborate with external vendors, academics, and technology providers.

Qualifications

Education: B.E./B.Tech/M.Tech/M.S. in Chemical Engineering, Biotechnology, or Pharmaceutical Engineering.

Experience: 3-6 years in process development or manufacturing within peptide, oligonucleotide, or small-molecule environments, with proven record of accomplishment in PAT and chemometrics implementation.

Technical Competencies

• Deep understanding of reaction, crystallization, solid-state transitions, and peptide purification processes, familiarity with drug product processes (oral solid dosage & parenteral will be plus) 
• Hands-on experience with inline/online/atline spectroscopic, scattering & microscopic techniques (Raman, NIR, FTIR, MS, FBRM, PVM, NMR). Familiarity with chromatographic and mass spectrometry based tools will be plus.

• Familiarity with MVDA, digital twins, and process-control strategies.

• Understanding of GMP validation, lifecycle management, and regulatory PAT expectations.

Behavioral Competencies

• Innovative and data-driven mindset with passion for process analytics and digital transformation.

• Excellent problem-solving, communication, and documentation skills.

• Ability to manage multiple projects simultaneously and collaborate seamlessly across R&D and plant.

Preferred Certifications / Tools
