Job description

Overview

Speechmatics is a cutting-edge applied AI Research company that is breaking down cultural barriers by building diverse and inclusive speech technology. We are looking for an experienced Machine Learning Engineer who can help us advance our automatic speech recognition (ASR) engines for Flow, our new Conversational AI companion and create interactive voice interfaces of the future that Understand Every Voice.

We are scaling models across millions of hours of audio and billions of parameters, training across dozens of GPUs to identify bottlenecks across our 50+ languages. Our main research focuses are large-scale self-supervised learning, building state-of-the-art speech pipelines and developing emotive text-to-speech (TTS) models.

What you'll be doing

• Working with a diverse group of engineers across Speechmatics.
• Scaling self-supervised learning models across hundreds of GPUs in the cloud.
• Experimenting with distillation or quantisation to speed up our models at runtime.
• Comparing compute efficiencies of architectures such as transformers and the impact on WER.
• Developing new, state-of-the-art AI features, from training models to shipping them to production.
• Advancing end-to-end speech models and researching new approaches to TTS.

We aim to onboard you quickly; you will often pair program to streamline production ML pipelines, review code, and tackle real-time factor (RTF) optimisation challenges, while brainstorming novel approaches for analysing model predictions with the team.

You’ll want to join our team if you

• Aspiring engineers keen to work on bleeding-edge speech recognition and representational learning.
• Experience owning areas of code and seeking alignment rather than requiring constant guidance.
• A proven track record of delivering results, moving fast, and keeping things simple.
• Enjoy working in collaborative and diverse teams.
• Have a growth mindset and enjoy developing oneself and others.
• Like solving challenging problems and optimising a stack of unfamiliar code.

We encourage you to apply even if you do not feel you match all of the requirements exactly. The list of requirements is intended to show the kinds of experience and qualities we’re looking for, but it is not exhaustive. If you are interested in the role, the team, and our mission, we would love to consider your application. We are open to conversations and look forward to hearing from you.

Who we are

Speechmatics is the leading expert in Speech Intelligence, using AI and machine learning to unlock business value in human speech worldwide. We work with a diverse mix of global companies, and our technology can integrate into customers' stacks regardless of industry or use case, making Speechmatics a go-to solution to harness information from speech.

Joining us means working with some of the smartest minds focused on cutting-edge projects and deploying the latest techniques to disrupt the market. We believe in putting people first and will help you develop your skills and provide tools to thrive. We offer Focus Fridays for focused work, Together Tuesdays for team meetings, and a hybrid work model with 2-3 designated office days per week.

What we can offer you

We support every stage of your career with training and development to reach your goals. We offer flexible working, regular company lunches, and birthday celebrations. Benefits include private medical and dental for you and your family, global work opportunities, generous holiday allowance, pension/401K matching, and a home office equipment allowance. Parental leave support varies by location to accommodate growing families.

At Speechmatics, our mission is simple: Understand Every Voice. We welcome diverse experiences, viewpoints, and identities, and celebrate every voice as a source of innovation and creativity.
