Manual workflows are a major bottleneck in substance use facilities, slowing down treatment, leading to clinician burnout, and worsening patient outcomes. Our tool seamlessly integrates with any EHR, eliminates tedious and repetitive workflows, and reduces administrative workload in real-time. We transform hours of manual data entry into minutes, improving accuracy and freeing up clinicians to focus on care.
We target a range of customers, from small Medicaid-funded clinics to large behavioral health networks, requiring flexible deployment and integration solutions.
We were funded in January and are rapidly expanding, with a list of 50 facilities signed up for our pilot.

We're building an AI-first insurance company from scratch. Not just adding AI to existing processes - we're automating the entire insurance value chain. Think of it as rebuilding the insurance stack with code instead of paperwork.
I'm part of the engineering team at Corgi. We need someone who can write solid Go code and isn't afraid to jump into React/TypeScript when needed. Our stack is cloud-native (AWS/GCP/DO), heavily containerized, and we're pushing hard on AI/ML integration.
Requirements: - 1-2 years of Go in production - Frontend experience with React/TypeScript - Cloud platform experience - Docker and database skills - Shipped real products to real users
This is an early-stage role (we're YC-backed) so you'll own features completely, from backend to frontend. We're in the office seven days a week - this isn't a role for those seeking work-life balance, but perfect if you want to build something massive from the ground up.
Note: We're looking for builders who ship. If you prefer perfect code over working products, this probably isn't the right fit.
Compensation: Competitive salary + equity

Tech Stack - We have a cloud-native architecture, and we use Google Cloud Platform extensively. We regularly evaluate new technologies to see which ones we want to adopt. Some other tech stack basics: a) Languages/frameworks - C#, Python, Typescript, React b) Databases - PostgreSQL, MongoDB, Redis, ElasticSearch
Also,
a. Our scrum teams own the entire software development life cycle, including design, development, testing, and maintenance. b. We prioritize speed and flexibility. New code is deployed to production every single day.
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.

* Manifesto Manufacturing is important. It’s the fundamental industry on which everything else is built. We take it for granted. In 1989, 35% of the entire software industry was manufacturing systems. Back then, services, hand holding, customization, and consulting were necessary to get the systems to where they are today. What was the first massive burst in productivity from technology has stagnated into incremental diminishing returns and exponentially increasing complexity. We can only continue to add complexity for so much longer until the whole system collapses. "Any intelligent fool can make things bigger and more complex. It takes a touch of genius and a lot of courage to move in the opposite direction." Manufacturing is important. We must deliver a touch of technological genius to reintroduce simplicity, efficiency, and integration.
We're looking for a backend-leaning fullstack dev. Highlights:
- We're a 5-person startup in San Francisco (hybrid: 3 days/week in office)
- We're working on a b2b SaaS for managing/analyzing cloud costs for really large companies.
- The domain isn't cool, but the complexity is fractal and the need is huge.
- Typescript/Python/Clickhouse currently
- Our founders are also the founders of the Duckbill Group, an AWS cost consultancy. As a result, we've got a great, built-in sales pipeline.
- As a result of that, we're bottlenecked on our ability to just build the features our users clearly want.
- So we're hiring a 4th engineer: a backend-leaning full stack dev to build and own large swaths of this thing we're creating!
- We're looking for someone with 5+ years of experience, though probably closer to 8-10, depending on the person and the experience.
- Comp is 175k-200k base, 0.5-0.75% equity.

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 more than 200 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 :)
