Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US-only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django and Hotwire Turbo (an HTMX-like framework). Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.
