MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time 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.

Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule.

Saildrone | Multiple Roles | Onsite/Hybrid (US Only) | SF Bay Area (Alameda) | Full-Time | https://www.saildrone.com/

Saildrone is the world's leading collector of ocean-related in situ data via uncrewed vehicle, above and below the sea surface. We work with navies across the world to deliver insights about waterways, contribute to safety of life at sea, and mitigate illegal fishing and trafficking. Additionally, we work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, or counting biomass to establish fishing quotas.

Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just announced a large partnership with Lockheed Martin[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand and secure our planet.

Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.

In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.

You can see a list of open positions on our career page: https://www.saildrone.com/careers

Profitmind | Web Scraping Junior Developer | Remote or Pittsburgh | $90-110k | Full-time | https://www.profitmind.com/

At Profitmind, we're building massive-scale ecommerce datasets to use in AI training/inference, and we need a junior engineer to help develop the scraping infrastructure for product data. You'll be reverse-engineering undocumented APIs, handling anti-bot systems, and dealing with edge cases like pagination limits, rate limiting, and sites that change their protection schemes without warning.

The work you'll be doing is in the hot path of our company, so the systems you will build need to be performant and maintainable. You should have solid Python skills and experience scraping ecommerce websites and APIs. You should also like the slightly-obsessive investigative nature of the work.

If you worked in scraping or botting in the past, please hit me up!
