New Lantern is hiring software engineers to help build an AI copilot [1] for radiologists.
Radiologists are experts at diagnosing disease in medical images, but they spend over half their working hours on tasks that have nothing to do with diagnosis: reading prior reports, transcribing handwritten notes, taking manual measurements, dictating reports, and chasing down follow-ups. New Lantern is building an AI copilot for radiologists to automate this non-diagnostic work, so radiologists can focus on what they do best: caring for patients and interpreting images.
We are starting to find product-market fit and recently raised a $19M Series A from Benchmark [2]. Demand for our product is growing, and we're hiring software engineers in San Francisco to help us scale our product and our team. We work together in person five days a week from our office in Jackson Square.
Engineering is at the heart of New Lantern. Our engineers work directly with our founder/CEO, our staff radiologist, and our end users to build features that radiologists rely on daily. Everyone has real ownership and autonomy, moves quickly, and ships meaningful work frequently. We're a small, sharp team of frontend, full-stack, and backend engineers building a React-based web app backed by Python services, cloud infrastructure, and LLMs.
I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai.
[1] We translate "AI copilot" to "AI radiology resident" when we speak with medical professionals, but the former is the clearest way to communicate what we're building here.

We have an awesome work environment: We are a remote first company (before Covid!). We do continuous integration, continuous deployments, code reviews, code pairings, profit sharing, and most of communication is async via GitHub.
We value super strongly transparency, do open books, have a public roadmap, and contribute to the EFF.
Apply at: https://serpapi.com/careers

We are an early-stage, well-funded startup making humans and computers work together more efficiently. Experienced team from Apple AIML and other great companies.
We will be opening several roles soon, but are previewing this one early: Staff Engineer / Startup Polyglot Engineer.
You'll enjoy this role if:
- You like going 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product
- You are innovative, get satisfaction out of learning new things, and thrive in an environment of uncertainty and opportunity
To succeed, you should:
- Have the wisdom to know when to take the fast route vs when to step back and clean up your mess
- Be capable and excel on your own, but be humble and communicate well with others as projects require more collaboration
- Be versed across many programming languages (e.g. from C++/Java/Swift to Go to JavaScript or Python)
- Have worked on many types of projects and software -- have you built servers, written games, shipped native apps, and vibe-coded (kidding) web apps? If so, you're a fit.
- Be versatile and work both high level and low level, on old tech and new. Have you both prompt-engineered an LLM AND tweaked the code that decodes tokens in your own local LLM runner? If so, you're a fit.
All said, we're looking for the stereotypical "startup engineer" who can move between different components, be creative, be flexible, take ownership, and get things done. We have a complex, challenging product, but one that's amazing to work on and that will soon change how people think about working with each other and with AI.

At Edra we built a new, proprietary method of learning that allows LLMs to understand and automate business processes.
Founded by Eugen and Yannis, former co-heads of Forward Deployed AI Engineering at Palantir. We believe that as we get closer to AGI, the ability to teach models what you want them to do will become the key bottleneck in deployment to enterprises, and traditional training approaches won’t cut it. We named the company Edra for “the seat of the teacher”.
Edra AI is a novel learning system, deployed with several customers and are looking to scale up. Backed by top-tier investors from the Palantir ecosystem with offices in New York and London.

I've spent the last 18 months iterating on Phrasing, a language learning app for polyglots. It's finally reached a stable point, and we're starting to get Daily Active Users. I've been using it every day for over a month now to learn over a dozen languages, and have been blown away at my progress.
However, I've really reached the limit of what one engineer can do alone. I'm looking for someone to help me make it go brrr. Someone who would love to iterate on our in-house sync engine, make our monolithic postgres database purr, and wouldn't be scared of a little machine learning.
The product is built in Elixir on the backend, ClojureScript on the front-end. There are no experience requirements so long as you're committed, capable, and hungry.
I'm really trying to do something different with Phrasing. No investors, no hyper-scaling, no enshittification - just a relentless pursuit of mastery and a delightful product.
If any of this is speaking to you, get in touch at hackers [at] phrasing [dot] app.

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.

MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.
We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

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.
Pleas remember that we are looking for NYC local only, no exceptions at this time :(.
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://grnh.se/f303c36d6us!
