• Take ownership of features from initial design through to deployment, monitoring and ongoing improvement.
• Ensure system reliability, performance, security and uptime across production environments.
• Work with enterprise clients to scope technical requirements, define success criteria and support proof-of-concept projects.
• Translate client needs into practical technical solutions and communicate architectural decisions clearly to non-technical stakeholders.
• Monitor deployed AI agents, evaluate their performance and report on business value and outcomes.
• Mentor junior implementation engineers and contribute to best practices across the engineering team.
• Collaborate with internal teams to feed client insights and technical learnings back into product development.

• Experience working with queues and event-driven architecture.
• Ability to explain technical concepts and trade-offs to non-technical stakeholders.
• Previous experience mentoring or leading junior engineers.

Advantageous Experience

• Experience with the WhatsApp Business API, voice AI or telephony integrations.
• Practical knowledge of AI agent orchestration, Retrieval-Augmented Generation (RAG) or LLM evaluation.
• Familiarity with Supabase or workflow automation tools such as n8n.
• Experience in insurance, telecommunications or financial services.
• Understanding of POPIA and the responsible handling of personal information within AI systems.
• Exposure to technical scoping, client consultations or pre-sales activities.
