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

WireScreen (Series A) | Senior Software Engineer | NYC - hybrid | Full-time | $165k-$210k base + equity | https://jobs.ashbyhq.com/wirescreen/e9d8e7e3-c737-43ee-8c7e-...

WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.

We’re looking for senior software engineers to build our data platform and help us ingest and model messy, unstructured data into insights and actionable intelligence. At the heart of this is a 50m+ entity knowledge-graph with 200m+ relationships represented - and we need your help to build a system that can scale this up by an order of a magnitude. Today, we mostly use Python, Postgres, Airflow and Pyspark.

If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.

Apply here: https://jobs.ashbyhq.com/wirescreen/e9d8e7e3-c737-43ee-8c7e-...

Quantum Rise | Chicago or NYC (preferred), Remote for the right candidate | Full-time | No visa sponsorship | https://www.quantumrise.com/

Quantum Rise is an AI-forward consulting startup serving the middle market, across multiple industries. Clearly many companies are struggling to understand how to leverage artificial intelligence in their day-to-day operations, to understand what their existing workforce now needs to know, or to understand whether they're about to be disrupted. Many have business problems which "traditional" machine learning could help with even before the current GenAI hype cycle, but for whatever reason hadn't prioritized doing so until now. We try and help getting a handle around these issues and designing outcome-driven solutions.
