Technical Lead

• Technical Leadership and Architecture
• Lead design and implementation of scalable backend systems using Node.js, TypeScript and microservice architectures.
• Define and enforce coding standards, design principles and architecture guidelines across the engineering team.
• Ensure platform scalability, reliability and security through robust design and proactive system monitoring.
• Architect end-to-end AI-powered features from prototype to production, balancing speed with engineering rigour.

• Design, build and maintain AI/ML-powered systems including chatbots, voice agents, RAG pipelines and multi-agent architectures.
• Own prompt engineering practices across the platform — crafting, testing, versioning and optimising prompts for LLMs (OpenAI, Azure OpenAI and open-source models).
• Implement evaluation frameworks to measure LLM output quality, hallucination rates, latency and cost.
• Integrate AI models into production environments and manage model lifecycle, versioning and observability.
• Leverage Azure Machine Learning, OpenAI APIs and multi-agentic frameworks (LangChain, AutoGen, CrewAI) to build intelligent, data-driven experiences.
• Champion the use of modern AI development tooling (Cursor, GitHub Copilot, Claude) across the engineering team.

• Lead architecture and integration of Speech-to-Text (STT) and Text-to-Speech (TTS) pipelines for real-time voice AI applications.
• Evaluate and integrate providers such as Deepgram, ElevenLabs, Azure Speech and Whisper — balancing latency, accuracy, cost and voice quality.
• Build and optimise end-to-end voice agent flows: ASR to LLM to TTS with low-latency streaming and graceful fallback handling.
• Where applicable, integrate with telephony platforms such as Twilio, Vonage, LiveKit or SIP/PSTN-based systems — including call routing, IVR design and inbound/outbound call orchestration.

Infrastructure and DevOps

• Own cloud infrastructure strategy on Azure — including AKS, App Services, Azure Functions, networking and cost governance.
• Architect for high availability, auto-scaling and fault tolerance. Define SLOs and drive reliability improvements.
• Manage CI/CD pipelines, containerisation (Docker, Kubernetes), secrets management and deployment automation.
• Maintain and optimise MySQL and cloud data services (CosmosDB, Firebase, Data Lake). Ensure query performance and cost efficiency at scale.
• Establish infrastructure-as-code practices (Terraform, Bicep or equivalent) and enforce security best practices.
• Implement robust observability: distributed tracing, structured logging, alerting and dashboards.

• Drive backend development while ensuring smooth frontend integration using React, Next.js and modern UI frameworks.
• Deliver clean, maintainable, testable and well-documented code. Uphold high standards through code reviews.

• Work directly with the Co-Founder to translate product vision into a clear technical roadmap — providing candid perspectives and proactively flagging risks.
• Communicate complex technical concepts clearly to non-technical stakeholders.
• Lead, mentor and upskill engineers across multiple teams. Conduct regular code reviews and knowledge-sharing sessions.
• Collaborate with PMs, BAs and designers to ensure technical feasibility, clear scope and timely delivery.
• Foster a culture of ownership, transparency and continuous improvement.
