Connect and transform datasets into usable insights and dashboards.
Automate workflows from lab data → customer screens.
Polish UX flows and simplify complex interactions.
Balance speed and quality with pragmatic testing and observability.
Mentor lightly—unblock, accelerate, and give direct feedback without red tape.
You might be a fit if you...

Care deeply about usability and intuitive data visualization.
Communicate clearly and thrive in async, customer-focused environments.
Have experience with cloud (AWS/GCP), CI/CD, and security best practices.
What this role is not
