Ascertain is a healthcare AI startup backed by Northwell (New York's largest health system) and Deerfield. We're a small team automating the painful admin work that clogs up the U.S. healthcare system — things like prior authorizations, discharge planning, and insurance claims. Our goal is simple: give time back to clinicians so they can focus on patient care, not paperwork.
We've found early product-market fit and are growing the team thoughtfully. We're hiring senior engineers across the stack: backend, frontend, and AI/LLM. We're NYC-based and hybrid (most of us come in ~3 days/week). We're not counting badge swipes — we just want teammates who want to be in the room with us often enough to build trust, have fun, and work on hard problems together!
What we're building:
* A general-purpose automation platform for healthcare ops, powered by LLMs
* A system that reads unstructured documents, fills out payer forms, and explains rejections
* Tools to automate patient discharge planning in hospitals
* A foundation for making AI in healthcare safe, observable, and human-in-the-loop
What we're looking for:
* AI Engineer — experience productionizing LLM apps (agents, RAG, embeddings); solid Python; knows how to build ML systems that ship
* Backend Engineer — strong Python/FastAPI; infra-savvy (K8s, Terraform, Docker); thoughtful about API design and scalability
* Frontend Engineer — React/TypeScript expert who's opinionated about UX and happy to dip into backend when needed
More importantly, we're looking for engineers who like open-ended, ambiguous challenges, and want to work with a tight-knit, high-trust team to solve real-world problems.
I'm a Principal Engineer here — if anything here resonates, drop me a line at john@ascertain.com or apply at our job board using https://lnkd.in/e5ZnGuqH!
SerpApi is the leading API to scrape and parse search engine results. We deeply support Google, Google Maps, Google Images, Bing, Baidu, and a lot more.

We do continuous integration, continuous deployments, code reviews, code pairings, profit sharing, and most of communication is async via GitHub.
Our current stack is Ruby, Rails, MongoDB, and React.JS. We are looking for more Junior and Senior FullStack Engineers. We have an awesome work environment: We are a remote first company (before Covid!).
We very strongly value transparency, do open books, have a public roadmap, and contribute to the EFF.

• You haven’t actively learned a new tool or hobby in the last year.

Fullstory provides privacy-preserving session replay and analytics for websites and mobile apps. Our session replays are nothing short of magical - they look almost like a video of the user's screen - and the combination with analytics creates eye-opening insights.
We have several engineering roles open. The fullstack roles are going to be working with Go (golang), gRPC, Solr, BigQuery/BigTable, Kubernetes (K8S/GKE), and more on Google Cloud Platform (GCP) for the backend, and then TypeScript & React for the frontend.
USA:
* Senior Software Engineer, Full-stack, Application Experience - $160,000 to $190,000 (US) - https://www.fullstory.com/careers/jobs/1a014b19-d805-4547-9a...
* Senior Software Engineer, iOS - Objective-C, Rust, Swift, and smaller amounts of other languages. Note that we're not building apps. It's about taking things apart, seeing what makes them tick, and figuring out how to get at the bits we need without negatively impacting the app experience. (Or using any private APIs!) It's part reverse engineering, part systems programming, and part library development. Low-level knowledge of Swift and SwiftUI would be particularly helpful. - $176,000 to $207,500 (US) - https://www.fullstory.com/careers/jobs/ab3f8ecb-ee1f-4431-a0...

I take about 5 weeks vacation a year, in addition to ~3 weeks worth of company holidays (federal holidays + the week of Christmas to New Years.)

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and already have >500 organizations using our product.
Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)
