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.

Buildings account for ~40% of all emissions. There is a ton of federal, state, and local programs to help decarbonize buildings -- but this money is difficult to access, trapped behind complicated program requirements, uncertain eligibility, lack of clarity, and long payout cycles. We make access to these incentives easy by abstracting away the policy complexity and letting our users focus on their projects. Our platform serves contractors, homeowners, incentive providers and implementers, and equipment manufacturers.
We're hiring Backend Engineers for full time roles.
We're well-funded, have a lot of customer traction, and are rapidly expanding the team. Our product vision is very clear -- the bottleneck is skillful, user-focused execution.
Tech stack: Python (FastAPI, pyright), Google Cloud (GKE), React (Typescript, react-query, auto-gen API client)
We value curiosity, ownership and collaboration. Interest in energy, climate, and sustainability is a plus.

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 300 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 :)

Hey — we’re building AI-powered tools to help law firms work faster, smarter, and with less busywork.
Our first module is an AI call center that transcribes and classifies calls to help teams prioritize urgent cases. But that’s just one part — we’re building an end-to-end platform that automates the entire case lifecycle, from intake to resolution.
We’re a small, senior team based in LATAM. You’ll be working directly with the founders and building features from scratch. No layers of approval, no legacy code — just thoughtful product work, shipped fast.
If you're excited about solving real problems, working closely with strong engineers, and being part of something early (but real), we’d love to hear from you.
Our tech stack is : Python, Javascript/typescript
