SUMMARY:

Recruiter:
Network Recruitment
Job Ref:
NFP /HN
Date posted:
Friday, June 27, 2025
Location:
Johannesburg, South Africa
SUMMARY:
Build the Future of AI-Driven Customer Engagement.

Are you fluent in Python and passionate about shaping the future of intelligent conversations?

We’re searching for an AI Engineer who’s ready to design, build, and scale voice bots, chatbots, and next-gen NLP solutions, including for under-served African languages.

If you thrive at the intersection of language, data, and innovation, then this is your launchpad.
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
