P3P3 — Mid-Level Professionalhigh0.90approvedglobalv1

Develops, characterizes, scales, and transfers downstream purification processes (chromatography, filtration, viral clearance, harvest/clarification) for recombinant protein and biologic drug substances. Distinct from Upstream Processing (cell culture/fermentation) and Analytical Development (assay development); this focus owns the recovery and purification train from cell harvest through bulk drug substance, including yield, purity, viral safety, and CMC control strategy.

Sets up, operates, and maintains laboratory instruments including ÄKTA chromatography systems; prepares solutions, packs columns, and runs downstream unit operations with low bioburden risk.
Executes basic analysis of process samples (absorbance, pH, conductivity) and records detailed observations of experimental deviations.
Performs clean-in-place (CIP) and sterilize-in-place (SIP) procedures and follows SOPs in accordance with a cGMP environment.
Reviews data and reports results at team meetings; performs basic troubleshooting of experimental data and calibrates associated equipment.

Independently executes chromatography and filtration experiments for development, optimization, and scale-up of recombinant protein purification steps following general instruction.
Designs experiments related to viral clearance, resin/buffer screening, and unit-operation optimization, applying Design of Experiments (DoE) to minimize runs.
Owns development of a single downstream unit operation or product with limited oversight, making routine development and design decisions.
Applies Quality by Design (QbD) principles to process development and develops representative scale-down models from commercial-scale operations.
Authors and reviews source documents (batch records, development reports) supporting regulatory submissions; may mentor junior associates on instrument operation.

P3this profile

Owns process development for a product end-to-end, including process characterization and technology transfer, planning own work with milestone review.

Designs and analyzes process characterization studies including resin lifetime, operating ranges, and viral clearance validation.
Authors and reviews technical reports, procedures, and CMC sections of regulatory submissions; coordinates project activities across analytical and upstream teams.
Networks with senior scientists to align scale-down models and control strategy with commercial-scale operations.

Provides scientific and technical expertise for development and launch of new biological drug substances across a program, performing in-depth analysis of complex purification variables.
Selects development methods and leads the design of viral clearance, scale-up, and process characterization strategies for first-in-human and commercial processes.
Leads technology transfer of downstream processes to manufacturing sites, CMOs, and partner sites, coordinating across Analytical, Upstream, Manufacturing, and Quality.
Authors and reviews manufacturing batch records and CMC sections of IND and BLA submissions, influencing control-strategy decisions.
Leads, mentors, and coaches technical staff and may supervise project teams in downstream process development.

Provides technical leadership of biologic downstream process development for first-in-human and commercial processes, contributing to broad company objectives and pipeline strategy.
Advances the downstream platform process technical strategy and assesses new technologies, sciences, and industry approaches, working on broad assignments with high independence.
Acts as technical authority for downstream purification and leads matrixed project teams spanning Research, Upstream PD, Analytical, CMC, Manufacturing, Quality, Regulatory, and external CDMOs.
Defines end-to-end purification strategies focused on yield, purity, potency, consistency, scalability, and cost; shapes CMC control strategy, in-process monitoring, and operating ranges.
Serves as external spokesperson with partners and CDMOs and manages a portfolio of programs, building influential cross-functional networks.

Level guidelines
