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

Distru (https://www.distru.com) | Senior Software Engineer | AI Product Engineer | Senior Product Manager | REMOTE (Americas & Europe) | Full-Time

Distru is the #1 ERP in the cannabis industry. $3.5B in annual GMV flows through our platform, and most of the top cannabis brands and distributors in the US run their entire operation on us to stay compliant.

We're profitable, stable, and growing. No runway anxiety, and we're reinvesting into new product lines. We're an intrinsically motivated team that works without ego, is constantly learning, and genuinely cares about our people (5/5 on Glassdoor).

Distru is at an inflection point. We have deep market penetration in cannabis ERP, a new commerce layer (Distru Commerce, a B2B wholesale marketplace) live and growing, and a roadmap with a growing AI component. Our live AI Order Agent already lets buyers submit orders in any format from any source, killing manual data entry, the first of many bets on using AI to strip the repetitive heavy lifting out of running an ERP.

The roles: You'll own mission-critical parts of the product end to end, from planning and design through implementation, testing, and shipping. You might work on AI-native features (order/purchase intake, smart product matching, systems that learn from user feedback), Distru Commerce storefronts and ordering, manufacturing and distribution workflows, cultivation mobile tools for the floor, or compliance integrations with state systems like Metrc. These are high-ownership roles: you'll partner directly with product, design, support, and our C-suite, and you'll get customers writing you personal "thank you" emails.

Stack: React + TypeScript, Elixir/Phoenix + GraphQL, PostgreSQL, React Native, LangGraph

Stripe | Hybrid (50% of time in Toronto office) | Senior Go developer

We're looking for a senior-level Go developer who can design and ship idiomatic code our users love to work with. We can all write Go that compiles, but don't always know what best practices for 3rd party code are (in the Go ecosystem specifically). Ideal candidates are a part of the Go community / ecosystem and know what the current best practices are. They also probably have TypeScript experience (most of our tooling is TS) and in a perfect world, Ruby/PHP ecosystem knowledge (the other languages we're currently seeking expertise in). But, if we get a Go expert who's willing to learn a bunch of TypeScript, that probably works!

JD and application: https://stripe.com/careers/listing/backend-engineer-develope...

The best way to apply is to go through the form on the site. Happy to answer questions here though! It's a fairly unique role.

Vitalize | Full-time Engineer | San Francisco (hybrid)

What we do: Hospitals run critical operations (staffing, labor planning, and capacity) on spreadsheets, phone calls, and gut instinct. Labor is the biggest cost and hardest operational problem, and it’s still largely manual. Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.

Traction: - Launched Jan 2024; ~$8M committed ARR across 10+ health systems (deals ~$300K–$2M) - Live in 20+ hospitals and growing quickly - ~$37M raised (Oak HC/FT, Norwest, .406, plus customer-investors MemorialCare & Rochester Regional Health)

How we work: We’re extremely customer-obsessed: everyone visits customer sites (including engineering) and we regularly build alongside operators to solve real problems (not hypotheticals). High ownership, high candor, high velocity.

Aeolus | DevOps Engineer | San Francisco, CA (onsite) | Full-Time

Aeolus is seeking an exceptional DevOps Engineer to take ownership of the cloud infrastructure and deployment systems that power our mission in applied atmospheric science.

In this role, you'll be the technical foundation our scientists, ML engineers, and software engineers build on. Responsibilities include designing and operating cloud environments, deployment pipelines, and infrastructure-as-code that keep our systems reliable, scalable, and fast. Our ideal candidate has extensive experience in HPC environments.

Apply at https://www.aeolus.earth/careers/devops-engineer

Tonic AI (https://tonic.ai) builds the data infrastructure behind modern AI. We generate the synthetic environments that agents are trained and tested in, and we de-identify real enterprise data so it can be used safely in training and evaluation. Eight years in, we work with frontier AI labs pushing the edge of what models can do, and with hundreds of enterprises including Fidelity, Comcast, eBay, and Vanguard, on the data problems that sit at the center of where AI is going next.

We are looking for a data scientist with 8+ years experience (or 3+ with relevant PHD). In this role you will:

++ Design and build the systems that generate longitudinally coherent synthetic environments for agent training and evaluation, including persona modeling, task generators, and verifiable ground truth.

++ Build and maintain synthesis models that generate realistic replacement values at very large scale, preserving format, statistical distribution, and semantic consistency so de-identified data stays useful downstream.

++ Train and improve the NER models behind our entity detection, driving accuracy and recall across free text, structured fields, and mixed enterprise data at scale.

++ Build evaluation infrastructure that grades agent outcomes, not just traces, and produces real discrimination between frontier models on real tasks.

++ Fine-tune and evaluate open-weight models on Tonic-generated data, and turn benchmark results into product and research direction.

++ Expand coverage into new domains, languages, and entity types, and handle the long tail of formats and edge cases that real customer data throws off.

++ Own model evaluation across the board: precision and recall on detection, utility preservation on synthesis, and outcome-level grading for agents.

++ Optimize inference so models run efficiently on large volumes of sensitive data inside customer environments.

++ Partner directly with frontier labs and enterprise ML team to turn hard data problems into shipped model improvements.

++ Set technical direction for a small, senior team and raise the bar on rigor, reproducibility, and shipping.
