Meet the team:

As a key member of the material science group within Dexcom’s research and development organization, the Staff membrane formulation scientist is responsible for developing and validating novel membrane designs and formulations to support biosensor products.  The individual is expected to have clear understanding of the technical and business challenges associated with medical device material component product development and will be responsible for developing, validating, and implementing technical solutions that meet the objectives.  In this capacity, the scientist will work cross functionally to drive the creation and maintenance of design requirements, down select formulation chemistry, develop and validate design/process to final specification, identify and mitigate risks, interface with external partners and collaborate with internal stake holders to drive the project to completion.

Where you come in:

• You will define and develop formulation strategies for biosensing modalities, maintaining relevant domain expertise and driving formulation excellence.

• You will design and develop thoughtful DOE and testing protocols conducive to generation of rapid insights on structure-function behavior and design optimization.

• You will plan and execute experiments, identify critical variables and design trade-offs, screen and down-select formulation candidates for form-fit-function on targeted applications while maintaining a manageable business / commercial risk profile.

• You will document experimental details and analysis, author technical reports, present results to a wide audience of stakeholders, including progress reports, design reviews and phase exits.

• You will verify that performance objectives have been met via pre-clinical and clinical evaluations of novel designs.

• You will design and develop formulation-related validation protocols such as formulation process, formulation pot-life and shelf-life, lead the validation execution and author final reports.

• You will identify, procure, and qualify critical raw materials and manage vendors to support formulation development and commercialization.

• You will perform chemical synthesis and modification on identified lead candidates. 

• You will contribute to new IP generation efforts and assist with evaluation of technical, clinical, and commercial risks.

• You will understand and adhere to all relevant laboratory safety protocols, chemical hygiene, and dispose chemical waste according to company and local EHS regulations.

• You will partner with design teams to align on design requirements, develop and test new sensor prototypes.

What makes you successful:

• You demonstrate knowledge of, and experience with, polymer solution physics and material science for product safety and form, fit, and function - preferably in Class III medical applications.

• You have expertise in polymer science, material formulation engineering, and membrane separation engineering.

• You have experience with biosensor electrochemistry and enzyme engineering is highly desirable.

• You have experience with experimental design& planning, assay development, statistics, DOE techniques, data analysis methods and software (JMP, Python, or Matlab preferred).

• You have very strong analytical and experimental skills for small molecules, polymers, additives, solution physics, and condense state (HPLC, LC/MS, Viscometer/Rheometer, Mechanical, DLS, Zeta potential, SEM/EDX, XRF, confocal microscopy / interferometry, FT-IR, NMR, diffusion, and electrochemical characterization).

• You have experience with thin-film characterization (morphology, thickness).

• You are highly organized and detailed oriented.

• You have excellent communication (written and verbal), collaboration, and interpersonal skills.
