What are the key skills and qualifications needed to thrive as a Temporary Assay Development Scientist, and why are they important?

To thrive as a Temporary Assay Development Scientist, you generally need a degree in biology, chemistry, or a related field, with experience in assay design, optimization, and validation. Familiarity with laboratory instrumentation, data analysis software, and experience with techniques such as ELISA, PCR, or cell-based assays is typically required. Strong problem-solving abilities, attention to detail, and effective collaboration and communication skills distinguish top performers in this role. These skills ensure reliable assay results, support project timelines, and contribute to the overall success of scientific research and product development.

What are some common challenges faced by Temporary Assay Development Scientists, and how can they be managed?

Temporary Assay Development Scientists often encounter challenges such as adapting quickly to new laboratory environments, meeting tight project deadlines, and mastering proprietary protocols unique to each organization. Since the role is temporary, there may be limited time to familiarize oneself with existing workflows and team dynamics. Proactively communicating with colleagues, being organized, and seeking clarification early on can help overcome these hurdles. Staying adaptable and open to feedback is key to succeeding in this fast-paced, collaborative setting.

What are Temporary Assay Development Scientists?

Temporary Assay Development Scientists are professionals hired on a short-term basis to design, optimize, and validate laboratory assays, often for use in research, diagnostics, or pharmaceutical development. Their main role is to ensure that assays are reliable, reproducible, and meet the required standards for scientific or regulatory purposes. These scientists typically work in laboratory settings and may collaborate with other scientists or departments to support ongoing projects. Temporary positions may last from a few months to a year, depending on project needs and funding.

What is the difference between Temporary Assay Development Scientist vs Temporary Quality Control Analyst?

AspectTemporary Assay Development ScientistTemporary Quality Control Analyst
CredentialsBachelor's or Master's in Life Sciences, relevant lab experienceBachelor's in Life Sciences, laboratory experience in quality testing
Work EnvironmentResearch labs, product development teamsQuality control labs, manufacturing support
Industry UsageBiotech, pharmaceutical R&DManufacturing, pharmaceutical QC
Common Search IntentUnderstanding assay development rolesQuality testing and compliance roles

The Temporary Assay Development Scientist focuses on creating and optimizing laboratory assays for new products, often working in R&D settings. In contrast, the Temporary Quality Control Analyst primarily performs testing to ensure products meet quality standards during manufacturing. Both roles require laboratory experience but differ in their focus—development versus quality assurance—making them distinct yet related positions within the biotech and pharmaceutical industries.

Job description

DELFI Diagnostics, Inc. (DELFI Diagnostics) is developing next-generation, blood-based tests that are reliable, accessible and deliver a new way to help detect cancer. Employing advanced machine-learning methods to whole-genome sequencing data, the DELFI ("DNA EvaLuation of Fragments for early Interception") platform is built to address the highest-burden health challenges. DELFI Diagnostics prioritizes solutions that have the potential to save lives on a global scale, including for historically underserved populations. DELFI Diagnostics' platform relies on fragmentomics - the discovery that cancer cells are more chaotic than normal cells and, when they die, leave behind tell-tale patterns and characteristics of cell-free DNA (cfDNA) fragments. FirstLook Lung, for individuals eligible for lung cancer screening, is DELFI Diagnostics' first laboratory-developed screening test and can be part of routine blood work. FirstLook Lung uses millions of data points to reliably identify individuals who may have cancer detected through low-dose CT, including early stage disease with a negative predictive value of 99.8 percent. This test has not been cleared or approved by the FDA.
In our passionate pursuit to radically improve health outcomes, we serve humanity when we:
  • Lead with Science, Anchor in Pragmatism: We pioneer life-changing science by ensuring quality, transparency, and rigor at all times. We explore thoughtfully, experiment smartly, and deliver impact with conviction.
  • >
  • Build With & For All: We embrace diverse backgrounds to innovate and achieve together. We are not just building a product - we aim to disrupt the path of cancer for all - no matter geography or socioeconomic class
  • >
  • Put We over I: We are a home for high-performing people. Through teamwork, we build collective intelligence. Each of us wins when those we serve and those who serve with us--win. We show up with empathy, humility, and integrity at every step of the journey.

About the role
As Senior Director of Assay Development, you will own all development activities across DELFI's NGS-based cancer screening portfolio - driving the transition of innovative assays into verified, validated, and manufacturable IVD products. Reporting to the CTO, you will lead a team of scientists and functional leaders and serve as a key voice on product strategy across R&D, Quality, Regulatory, and Manufacturing.
This role demands hands-on scientific judgment to know when and where to take calculated risks - and when not to - leading with science while anchoring every decision in pragmatism to keep programs moving against ambitious timelines without compromising quality or integrity.
What you'll do
  • Own end-to-end assay development strategy across all LDT and IVD programs - from study design and execution through protocol approval, analytical validation, regulatory documentation, and FDA PMA submissions
  • >
  • Establish and enforce compliant analytical performance claims aligned to CLIA, FDA, and international IVD standards (21 CFR Part 820, ISO 13485, ISO 14971, IVDR)
  • >
  • Contribute to and/or lead Formal Design Reviews at key milestones; partner with Systems Engineering to ensure product requirements are fully addressed through design verification
  • >
  • Oversee reagent development and qualification, automated process scale-up, and statistical process control (SPC) for lab production environments
  • >
  • Lead design transfer activities across programs, ensuring robust handoffs to manufacturing and sustained assay performance at commercial scale
  • >
  • Report directly to the CTO; lead a team of scientists and functional leaders across assay development, validation, and manufacturing readiness
  • >
  • Design and own the operational infrastructure for the function - scalable processes, SOPs, design control frameworks, and traceability systems aligned to 21 CFR Part 820 and ISO 13485
  • >
  • Apply hands-on scientific judgment to make deliberate risk decisions - knowing where to push for speed and where standards are non-negotiable - keeping programs moving against ambitious timelines without compromising quality or integrity
  • >
  • Represent Assay Development at the executive level; align with the CTO, VP of Regulatory & Quality, and other senior leaders on portfolio priorities and product strategy
  • >

What you'll bring
Required
  • PhD or MS in Molecular Biology, Biochemistry, Biomedical Engineering, Genomics, or a related discipline
  • >
  • 12+ years in IVD and/or LDT assay development in regulated environments
  • >
  • Hands-on expertise in AV and design verification of multi-marker genomic or 'omic-based assays, with direct experience contributing to FDA regulatory submissions
  • >
  • Deep knowledge of IVD regulatory frameworks: FDA 21 CFR Part 820, ISO 13485, ISO 14971, and IVDR
  • >
  • Proven track record designing scalable processes, SOPs, quality systems, and operational infrastructure in regulated IVD environments
  • >
  • Demonstrated ownership of late-stage development programs through design transfer and manufacturing scale-up
