Job summary

Scorpion Therapeutics in Indianapolis is seeking an experienced peptide downstream specialist to drive transfer from development to pilot plant for early-phase API supply in kilo-scale and isolator environments.

You will execute purification/isolation, apply RP-HPLC, TFF, lyophilization, and support QA, safety, and cross-functional teams while documenting campaigns and deviations.

Qualifications

• BS or MS in chemistry/chemical engineering or related field.
• 3+ years peptide purification/manufacturing experience (synthetic peptide API/drug substance).
• Authorized to work in the U.S. full-time; no visa sponsorship.

Responsibilities

• Evaluate and facilitate transfer of peptide downstream manufacturing processes from development labs to pilot plant operations (kilo-scale and isolator environments) for early-phase cGMP API clinical supply.
• Perform peptide purification/isolation; assess purification methods.
• Use peptide downstream procedures: RP chromatography, TFF, lyophilization, precipitation & drying.
• Evaluate safety of incoming procedures with safety and process engineering.
• Order/stage chemicals; obtain reference materials and set up analytical methods.
• Reprocess/analyze analytical data; summarize/present chemistry and challenges.
• Execute plant familiarization steps; perform use-tests and document Definitive Lab Trials to confirm plant readiness.
• Maintain detailed lab notebooks for technical packages and replication.
• Author/review tech transfer plan, SOPs, batch records, campaign summary and deviation reports.
