Phlow is seeking a Quality Control Scientist, Manufacturing to support Quality Control activities at our pharmaceutical manufacturing facility in Petersburg, Virginia. This hands-on laboratory role will primarily provide in-process analytical testing in support of the development, scale-up, and manufacture of active pharmaceutical ingredients (APIs). The Quality Control Scientist will work closely with Manufacturing, Process Development, Manufacturing Science and Technology (MS&T), and Quality Assurance to provide accurate and timely analytical results that support manufacturing and process decisions. The candidate will personify Phlow’s shared values and culture and will work with the highest standards of safety, integrity, transparency, and ethics. 

This position requires flexibility to work varying shifts and schedules based on production needs. Because in-process testing must align with manufacturing activities, the individual must be able to adjust working hours as production schedules change, including early mornings, evenings, weekends or other non-standard work hours. 

The salary range for this position is $25.00 per hour to $30.00 per hour, with the final offer determined based on factors such as the candidate's experience, qualifications, skills, and education. In addition to a competitive base salary, this position is eligible to participate in Phlow's bonus and stock option programs. Phlow also offers a comprehensive benefits package that includes medical, life, and disability insurance; retirement savings plans; paid time off and company holidays; and education-related benefits. Many of these programs are fully funded or significantly subsidized by the company, reflecting our commitment to supporting the health, well-being, and professional development of our employees.    

• Perform in-process testing of samples generated during API development, scale-up, engineering, and manufacturing activities. 
• Execute established analytical methods to evaluate reaction progress, intermediates, process streams, and API samples. 
• Provide accurate and timely analytical results to Manufacturing and technical teams to support process decisions. 
• Provide QC laboratory coverage aligned with manufacturing schedules, including flexibility to work varying shifts or non-standard hours as production needs change. 
• Operate, maintain, and troubleshoot laboratory instrumentation used for in-process and QC testing. 
• Prepare samples, standards, reagents, mobile phases, and other laboratory solutions according to approved procedures.

• Experience executing established analytical methods and interpreting analytical results. 
• Strong laboratory documentation and data-integrity practices. 
• Ability to troubleshoot routine analytical and instrumentation issues. 
• Must have the flexibility to work varying shifts and adjust working hours based on the production schedule. Scheduled hours may change depending on production and in-process testing requirements. 
• Strong organizational skills and the ability to respond effectively to changing priorities in a manufacturing environment. 
• Strong interpersonal and written and verbal communication skills. 

Preferred Qualifications 

• Experience supporting API/drug substance manufacturing or development. 
• Hands-on experience performing in-process testing in direct support of manufacturing operations. 
• Experience working in a cGMP-regulated pharmaceutical environment. 
• Knowledge of ICH and USP requirements applicable to analytical testing and API manufacturing. 
• Experience with chromatography data systems such as Waters Empower or similar platforms. 
• Experience with analytical instrument qualification, calibration, and maintenance. 
• Experience with analytical method transfer, verification, or validation.
