About HumanSignal
What is HumanSignal?
HumanSignal is the company behind Label Studio, "the open-source standard for data labeling and evaluation," used by over a million practitioners worldwide according to the company's job postings, with "250,000+ Users" and "20,000+ GitHub Stars" cited on its own about page. The mission is "to help data scientists use data to teach ML/AI models how to make the best predictions." Beyond the open-source platform, HumanSignal acts as a human-data partner for companies building AI models — designing datasets from scratch, recruiting and managing domain experts to evaluate model output, and running everything through Label Studio. Founded in 2019 (the founding team famously reached the idea "while summiting Stok Kangri in the Himalayas... at 20,187 feet"), the company has "raised $30 million from proven investors, including Redpoint Ventures, Unusual Ventures, Bow Capital and Swift Ventures." Label Studio already powers "production ML/AI initiatives for large enterprises like Bombora, Geberit, Outreach, Trivago, Zendesk, and many more."
Where will I work?
You'll work remotely. HumanSignal describes itself as "a remote-first, distributed organization" with "team members working from North America, Europe, and South America." Engineering roles are posted as fully remote, and the company hires "across North and South America as well as Europe." Pay is set "based on regional compensation market rate ranges across the globe."
What is the HumanSignal team like?
HumanSignal is "all about our humans" and is "building a diverse and global team to solve the biggest problems in AI & Machine Learning." Its values center on open source ("democratize data-centric AI and put the power in data scientists' hands"), domain expertise, and community. Engineering is product-led — "not 'build what you're told,' but shape what we build" — working in a stack of Python/Django, React/TypeScript, Spark, BigQuery, Kafka, AWS, and Kubernetes, with trunk-based development and feature flags.
Work-Life Balance
The team runs "a six-week cycle known as 'Build and Ship' followed by a 'Cooldown.'" Four weeks focus on shipping features; the closing two-week Cooldown is "when we tackle technical debt, refine our integration processes, and wrap up those lingering tasks." On time off, HumanSignal says: "Time off is important. We offer a competitive vacation package and recognize your local holidays, so that you can take the time you need to rest and recharge."
Perks and Benefits
HumanSignal offers "competitive salary & ownership in the form of equity," a "competitive vacation package," and recognition of "your local holidays." As a remote-first team, it makes "an effort to bring our remote team together virtually, and in person" through an "annual team offsite to build relationships, collaborate and have fun," within an inclusive culture "where everyone can thrive and contribute."
