Help Us Shape the Future of Music Education
LabAMI’s mission is to harness technology to make learning music more accessible, intuitive, and meaningful for everyone, while keeping the essential human touch at its core.

As an early team member, your voice and skills will directly influence our product, culture, and company trajectory.
What We’re Looking For
- Strong skills in at least one programming language
- Passion for our mission and excitement to work in an early-stage team
- Ownership mindset and ability to thrive in a collaborative, fast-paced environment
- Preferred: iOS experience (Swift/SwiftUI/UIKit/etc.); shipped consumer apps
This is a remote, equity-only role with a mission-driven, flexible team that cares deeply about music and technology.

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.

Fullstory provides privacy-preserving session replay and analytics for websites and mobile apps. Our session replays are nothing short of magical - they look almost like a video of the user's screen (with private details redacted) - and the combination with analytics creates eye-opening insights.
We have several engineering roles open. The fullstack roles are going to be working with Go (golang), gRPC, Solr, BigQuery/BigTable, Kubernetes (K8S/GKE), and more on Google Cloud Platform (GCP) for the backend, and then TypeScript & React for the frontend.

* Senior Software Engineer, iOS - Objective-C, Swift, Rust, and smaller amounts of other languages. This role is part reverse engineering, part systems programming, and part library development.
