What does an internship assay development scientist do?

An Internship Assay Development Scientist assists in designing, developing, and optimizing laboratory assays, which are tests used to measure the presence, amount, or activity of a target substance. Interns typically work under the supervision of experienced scientists, helping with tasks such as preparing samples, running experiments, analyzing data, and maintaining lab equipment. This role provides hands-on experience in laboratory techniques and the scientific process, often within the biotechnology or pharmaceutical industries. It's an excellent opportunity for students or recent graduates to gain practical skills and exposure to real-world research and development environments.

What types of projects or experiments might an internship assay development scientist typically be involved in during their internship?

As an Internship Assay Development Scientist, you can expect to participate in hands-on projects focused on the design, optimization, and validation of biochemical or cell-based assays. Your daily tasks may include preparing reagents, running experiments, analyzing data, and troubleshooting protocols under the guidance of experienced scientists. Interns often collaborate closely with cross-functional teams, such as research scientists and quality control specialists, to ensure assay reliability and accuracy. This role offers a valuable opportunity to refine laboratory techniques, gain exposure to industry-standard instrumentation, and contribute to real-world research projects.

What are the key skills and qualifications needed to thrive as an internship assay development scientist, and why are they important?

To thrive as an Internship Assay Development Scientist, you need a solid understanding of molecular biology, biochemistry, and laboratory techniques, typically supported by coursework or experience in a related scientific field. Familiarity with laboratory equipment, data analysis software (like GraphPad Prism or Excel), and adherence to safety protocols is often required. Strong attention to detail, problem-solving abilities, and effective communication skills set candidates apart in collaborative research environments. These competencies ensure accurate experiment execution, reliable data generation, and valuable contributions to assay development projects.

What is the difference between Internship Assay Development Scientist vs Laboratory Technician?

AspectInternship Assay Development ScientistLaboratory Technician
Required CredentialsTypically pursuing or holding a bachelor's or master's degree in life sciences; internship experienceAssociate degree or relevant technical training; less emphasis on advanced degrees
Work EnvironmentResearch labs focused on assay development, often in biotech or pharma companiesGeneral lab settings performing routine testing and sample preparation
Employer & Industry UsageUsed in biotech, pharmaceutical, and research organizations for early-career rolesCommon across various industries for lab support roles

The Internship Assay Development Scientist role focuses on gaining experience in assay design and validation within research environments, often requiring higher education. In contrast, Laboratory Technicians perform routine lab tasks with less emphasis on assay development, serving as support staff in various industries.

Job description

What if...you could join an organization that creates, resources, and builds life sciences companies that invent breakthrough technologies to transform health care? 

In today's healthcare system, disease diagnosis often relies on invasive procedures, such as biopsies, which enable direct interrogation of cellular and tissue health at the suspected source of disease. Due to their invasiveness, cost, and general inconvenience to the patient, biopsies are often conducted after onset of symptomatic disease presenting one of the largest barriers to delivering interventions early in disease progression when they are likely to be most impactful. Flagship Labs 103, Inc. is a privately held early-stage company that is building advanced technological and computational platforms to pioneer the detection of cellular dynamics from minimally invasive biospecimens that can be leveraged to connect individuals to the most effective interventions to prevent onset and progression of disease. 

FL103 was founded by Flagship Pioneering, an innovation enterprise dedicated to originating and developing companies that invent breakthrough technologies that transform health care, agriculture, and sustainability. Since Flagship's founding in 2000, the firm has originated and fostered more than 100 scientific ventures including Moderna Therapeutics, Generate Biomedicines, and Indigo Agriculture. 

Position Summary:  

FL103 is seeking a highly motivated and experienced senior scientist to lead the design, development, optimization and validation of extracellular vesicle based in vitro assays to help diagnose health and disease. The successful candidate will be a driven, experienced scientist who is enthusiastic about developing state-of-the-art techniques to pioneer the detection of low abundance biomarkers from minimally invasive biospecimens in a multiplex format. The position will provide a unique opportunity to play a foundational role in the development of FL103's innovative bioplatform. 

Responsibilities: 

  • Optimize and troubleshoot ultrasensitive immunoassay protocols to detect EV markers 
  • Change assay reagents and components to optimize assay performance, driving increases in sensitivity and specificity 
  • Develop laboratory protocols and optimize workflows to build the foundation of FL103's platform 
  • Maintain scientific and technical expertise through familiarity with scientific literature 
  • Coordinate with Contract Research Organizations (CROs) and external collaborators 
  • Communicate experimental results effectively through oral presentations and written reports, ensuring clear and concise dissemination of information to the FL103 team 
  • Help lead, mentor, and build experimental team 

Qualifications: 

  • PhD in Chemistry, Biochemistry, Molecular Biology or a related discipline with 5+ years of post-graduate experience (industry preferred) 
  • Demonstrated experience developing immunoassays, protein detection methods, molecular diagnostics, etc. 
  • Experience in assay troubleshooting, validation and verification 
  • Clinical sample testing, including plasma and serum 
  • Demonstrated ability to be a thoughtful contributor to experimental design and data analysis 
  • Ability to manage multiple projects, working both independently and collaboratively within a dynamic team 
  • Excellent written and verbal communication skills to present results and scientific data to the internal team and/or collaborators 
  • Enthusiastic about playing a pivotal role in building the foundation of a new biotech company 

Preferred Qualifications 

  • General experience with extracellular vesicles  
  • Experience guiding products from concept through feasibility, validation and launch 
  • Experience working under a quality management system 
  • Demonstrated experience working with established standards related to development and validation of biomarker assays, including CLSI guidelines or working within a CLIA regulated environment
