Formal position title: Machine Learning Research Scientist (Speech & Language Technologies)

 

Job Overview: Intron is a health-tech startup building ASR for clinicians and patients with African languages and accents, helping reduce burnout from tedious documentation for already overworked doctors across Africa. Clinical Speech Recognition is ubiquitous in developed countries but virtually absent across Africa or underperforms with African accents. You can help fix that! Through the contributions of over a thousand African clinicians, we have created Africa’s largest and most diverse clinical speech datasets (10,000+ hours, 300+ accents, and 23 languages). Come put your superpowers to work doing ASR, TTS, Clinical NER, Machine Translation, and Generative AI!

 

Employment type: Compensation is based on experience, qualifications, cultural fit, and the number of hours available per week.

• ML Research Scientist (Full-time, Part-time): Remote, up to $5,000 full-time, up to $2,500 per mo part-time
• ML Research Graduate Intern (PhD/MSc, Full-time, Part-time): Remote (Part-time or Full-time) for 3-6 months. Up to $2,000 per mo full-time, up to $1,000 per mo part-time

 

Who You Are:

• Completed(ing) a graduate degree in Computer Science (PhD/MSc)
• Fluent with Python
• Machine learning and deep learning research/experience are required.
• Experience should go beyond basic fine-tuning, inference, and API calls to explore making architectural or algorithmic modifications to models, loss functions, optimizers, etc.
• Understand the math and core concepts that underly deep learning, e.g. gradient descent, momentum, regularization, overfitting, bias-variance, etc
• Research, projects, or publications in Automatic Speech Recognition and/or Natural Language Processing are required. 
• Experience working with deep learning frameworks (Pytorch, Tensorflow, etc.) and related tools.
• Experience with LLMs, conversational agents, text generation, or summarization is a plus but not required
• Experience with distributed training with multiple GPUs in the cloud (AWS/GCP/Azure) is a plus but not required
• Understands the theory and practice of the Design of Experiments and statistical analysis of results.
• Comfort collecting, manipulating, combining, and analyzing complex, high-volume, unstructured data from varying sources.
• Familiar with the techniques and limitations of observational studies.
• Publication record in top ML/DL conferences/workshops is highly desired but not required.

 

We are looking for people who are:

Growth-oriented: Strong desire to push your ideas into production, overcoming obstacles, ready to learn, and grow your skills to match any challenge.

Personable and Fun: You are great to work and talk with

User-focused: You are passionate about deploying models and applications that improve the lives of millions of users and enjoy research that has direct user impact.

Communicative and collaborative: You are able to work effectively with others. You will be working closely with other researchers, engineers, designers, product managers, user experience researchers, and customer groups to build product features and high-quality products.

Nimble: Balancing short-term execution with longer-term concerns, can pivot when necessary

Ownership: You have demonstrated feature development ownership, and can take initiative and responsibility for building, shipping, and maintaining core features, end to end.

 

How to apply: Please fill out the application form and upload your resume by clicking the “Apply” button below. Your resume should be in reverse chronological order showing your most recent experience/projects first. Under each experience, kindly provide 3 to 4 bullet points describing interesting problems you solved, achievements, or important lessons learned on the job. The Education/Academic qualification section should follow. Next, the achievements/awards section could follow. Lastly, include any other information you think may be RELEVANT to the role.

About the Founder

Tobi Olatunji is a physician turned Machine Learning Scientist with a passion for Global Health. 

Tobi’s journey to starting Intron is nothing short of epic. He’s worked with big names like AWS Health AI, Enlitic Inc., and Cambia Health Solutions building intelligent Natural Language processing tools for large health systems in Australia, Brazil, Canada, Japan, UK, and the US. He’s on the Advisory Board at Harvard’s OpenNotes Lab, pushing for responsible AI in healthcare. His research spans accented speech recognition, algorithmic bias, and more, with publications in top machine learning conferences like NeurIPS, EACL, Interspeech, and EMNLP.

With a mix of medical and tech degrees, including an MBBS, an MSc in Medical Informatics, and MSc in Computer Science at Georgia Tech, a certificate in Healthcare Management from Yale School of Management, plus three US tech patents, Tobi is a true innovator. He’s also a key member of the Commonwealth AI Consortium and the Research Director at Bio-RAMP Labs.
