Hello ✨

We're Happy Scribe, a 100% bootstrapped startup based in Barcelona.

We offer transcription and subtitling services by combining AI with the expertise of language professionals to create a 5-star product. We're working on one of the fundamental problems of this decade: speech-to-text technology.

We're just 10 people at the moment, but growing fast and profitable and we're building the team thoughtfully and with a lot of care.

Our data engine

The biggest open dataset in our field is Common Voice, a product of years of work from Mozilla. We believe to have the most powerful data engine (Users and transcribers label transcripts by proofreading them on the platform) for ASR. As of today, our dataset is 100x bigger than Mozilla’s, and we’re just scratching the surface of what’s possible.

Autonomous driving will be solved by a car company (Tesla), not by a fancy research lab. ASR will be solved by a transcription company. We aim to be this company. 👋

About the role

We’re looking for someone extremely excited to solve one of the biggest problems of this decade through Machine Learning.

For decades transcription at scale has been almost impossible, now with the advancement of ASR technology we are on the verge of having computers that understand speech better than humans. Today, almost all the infrastructure is in place but we'll need remarkable engineering to pull it off. This is where we need your help.

What will be your mission as an ML Engineer at Happy Scribe?

  • Build the most accurate Speech-To-Text. Forget about optimising Ads networks, recommending stuff, predicting customer behaviour and things like that. We're talking about converting Speech to Text and many related problems like Speaker Identification or Audio and Text Alignment.
  • Use our huge and growing dataset of transcriptions built by our amazing team of professional transcribers. We have one of the biggest datasets in the field.
  • Build all this almost from scratch and plug it to our platform that transcribes tens of thousands of audios every month.

This might be for you if...

  • You're a hacker. Your sharp view of what's the bottom line allows you to duck-tape systems at a speed that wouldn't seem possible.
  • You work close to the metal. Deep Learning is an engineering problem as much as a research problem. You make things fast and know UNIX well.
  • You're unfazed by the "boring work" because you understand the ultimate goal is maximising impact.
  • You care about the business implications of anything you build. You don't go after the shiny stuff, but see it as a balance of craft, speed, and the bottom line.
  • You can learn most technologies as you go. You're pragmatic about them, it's about the tools and tradeoffs, not ideologies.
  • You love steep learning curves, and are not afraid to learn about subjects that are outside of the comfort zone.
  • You get things done. There are lots of people who are really excited about tons of things. Only some of those are excited about completing things.
  • You care a great deal about your work. When something is off it's almost offensive to you.
  • Bonus: You're excited by someone buying gaming GPUs, which are 10x cheaper than datacenter GPUs, and building an in-house rack that enables large-scale training for a frugal startup.

Hiring Philosophy

We’re excited about people who are already experts in their fields as well as people who are not yet specialised but show high potential. By “high potential” we mean people who have demonstrated the ability to ramp up quickly in a new domain and produce results.

We are not credential-driven—rather, we want to understand your unique background and what you can contribute to our team.
