Rapport is fixing healthcare's broken payment infrastructure. Hospitals lose billions annually to opaque payer rules and outdated contracts. We're an AI driven platform that ingests contracts, claims, and policies at scale, transforming them into real-time pricing intelligence to help get providers paid what they deserve.
We are backed by top tier investors and already have one of the largest RCM operators in the country as our development partner. Founded by a healthcare tech veteran with two prior exits.

Thanks to our partnership, you'll work with massive real world datasets from day one. Stack: Python, SQL, FastAPI, LLMs and Agentic frameworks.
Role 2: Founding Data Engineer Architect our data platform from scratch. Build fault tolerant pipelines using Databricks that handle diverse sources, design normalization layers for healthcare data, and implement observability for production reliability.

Pareto.AI is in the premium data annotation space, focused on ethical, high-quality data annotation. We work with almost all of the frontier labs. We are a fully distributed, remote-first company with engineering teams spread around the world. Some of us work hybrid from our office in SF. There is essentially no restriction on where you're located as long as you're not from a sanctioned country and are willing to adjust to either a US or EMEA timezone.
We have a few full-time, fully-remote roles available. For those two below, we've recently restructured how we do engineering at Pareto and are looking to be very talent dense. I've hired successfully from HN multiple times in the past, so if you have expertise in those respective tech stacks I'd love to chat:
* Lead/Senior+ Backend Eng: https://jobs.ashbyhq.com/pareto-ai/569f4da0-801c-433a-978f-5...

BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, and Posthog, automate the operations work that lets them provide their customers with world-class product experiences.
We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.
Joining us will mean solving hard problems at the frontier of AI adoption, including:
- maintaining performance at scale
- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.
- building agent and workflow systems that automate real work for customers
- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly
- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems
Stack: Postgres / TS (Nest + React) / Hasura / EKS / S3 / LLM APIs / Python
Benefits:
- unlimited PTO
- $100/mo education stipend
- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work
- health insurance
ALSO LOOKING FOR: Senior Product Designer | $105k - $180k USD | Design + code in HTML & CSS (Tailwind)

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.

We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

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 are already rolling out across some of the largest care chains across Europe, including most of the NHS.
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 :)

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.
