MixRank processes petabytes of data every month through web crawling. Hundreds of customers use our data products, including Google, Amazon, Facebook, Intel, and Adobe, across industries such as finance, recruiting, sales, marketing, and security. We’re a fully remote company with a global footprint across 20+ countries. We’re growing, profitable, employee-owned, and have no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely 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 codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two 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 run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.
Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests.
Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.

I’m Kiran, Chief of Staff at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.
Hi I’m Devin.
Do you love hard problems? Do you find yourself thinking about new ideas on a daily basis? If so, you are the person I’m looking for!
Biz overview: Our phones camera rolls have 10,000+ photos and videos… most aren’t good but some are. Mitty analyzes the content, creates the idea from what exists, and edits the footage → presenting you with a finished video to post on social. Pretty neat huh! Well, that’s the idea. Also, hard to pull off, which is why I need you!
I'm the founder. You will be the first technical hire and own everything technical — pick the stack, make the architecture calls, write the code, and hopefully stay lead engineer for the life of the company. I’m technical but not good enough.
90-day goal: ship v1.
Helpful: ML/AI + video understanding / computer vision; mobile (iOS preferred); video processing/editing pipelines; comfort wiring up LLM + vision APIs (Anthropic, OpenAI, etc.) and can workout without micro mngmt.
What I’m trying to build: category leader in AI video creation around pre existing content (different than opus who is more podcast style), built toward an acquisition or Series B in ~3 years (Adobe, Canva, Meta, Google are the obvious acquirers).
Comp: $150k base (or more depending on skill) + performance bonus + founding-level equity scaled to experience.
Ps. I don’t expect you to be THE Expert at all of this. Just someone who is good to workout with and likes figuring things out.
Role + details: https://mitty.film/careers/first-engineer.html
Apply: email Devin@PineappleHi.com — a note plus anything relevant (resume, GitHub, things you've shipped).
