POSITION INFO :

Senior Data Scientist – AI Engineer

What You’ll Be Doing :

Engineer intelligent customer experiences using production-grade voice and text bots.
Build custom NLP and NLU models that power real-time conversations and call QA systems.
Deploy end-to-end AI pipelines for speech-to-text (STT), text-to-speech (TTS), and generative AI use cases.
Innovate for inclusion—develop language models that give voice to low-resource African languages.
Own the tech stack—from APIs and model deployment to cloud integrations across Azure and more.
Stay cutting-edge with ongoing research in LLMs, speech analytics, and Responsible AI.

Your Toolkit :

Languages : Python (a must), SQL, R, or Java

Frameworks & Tools : TensorFlow, PyTorch, Hugging Face, Git, Docker, and REST APIs

Tech Concepts : NLP, LLMs, STT / TTS, QA systems, and MLOps

Bonus Points :

Experience building bots in contact center or BPO environments

Knowledge of African language data models

What We’re Looking For :

A problem-solver at heart with a knack for translating complex data into smart solutions

Someone who communicates clearly with tech teams and business leaders

A passionate learner, eager to explore new tools and technologies

A self-starter who thrives in Agile, collaborative squads

Committed to ethical, scalable, human-centric AI

Minimum Requirements :

Honours Degree in AI, Computer Science, Data Science, or similar (Master’s is a bonus)

2-4+ years of experience building AI / NLP / LLM systems

Hands-on experience building bots, speech tools, or AI-powered engagement systems

Why This Role Stands Out :

You’ll work on real-world AI projects, not prototypes that never see the light of day

Join a tech-forward team building at scale, with impact across Africa and beyond

Be part of a mission to democratize voice tech and AI in underrepresented languages

Growth is not optional—it’s part of your job description
