You will drive technical innovation, mentor junior engineers, and translate complex business requirements into scalable, high-impact AI systems.
Key Responsibilities
- End-to-End Development: Own the full AI lifecycle, from conceptual design and architectural planning to model training, evaluation, and production deployment.
- Multi-Agent Systems: Architect and implement sophisticated multi-agent workflows and agentic systems using frameworks like LangChain, LlamaIndex, Langraph and OpenAI SDK to solve complex enterprise problems.
- RAG & Model Optimization: Design robust Retrieval-Augmented Generation (RAG) pipelines using vector databases and execute precise fine-tuning of LLMs (e.g., GPT, Claude, LLaMA) using techniques like LoRA/QLoRA.
- Deployment & MLOps: Ensure systems are production-ready, scalable, and secure. Implement effective monitoring, evaluation Technical Leadership: Mentor junior engineers, conduct code reviews, establish engineering best practices, and collaborate with cross-functional teams (Product, Data, DevOps) to deliver high-quality solutions.
Required Skills & Experience
- frameworks (e.g., LangSmith, AgentOps), and technical guardrails to mitigate hallucinations and ensure compliance.
- Experience: Minimum 5+ years of progressive, hands-on experience in AI/ML engineering, with a proven track record of delivering end-to-end enterprise-grade AI solutions.
- GenAI Expertise: Deep understanding of transformer architectures, prompt engineering, and the Generative AI development lifecycle.
- Framework Proficiency: Expert knowledge of Python and AI orchestration frameworks (LangChain, LlamaIndex).
- System Architecture: Experience building, deploying, and maintaining high-availability APIs and scalable systems on major cloud platforms (AWS, Azure, or GCP).
- Communication: Ability to articulate complex technical concepts and project statuses to both technical teams and executive stakeholders.
Qualifications
- Bachelor’s or Master’s degree in Computer Science, Artificial Intelligence, Machine Learning, or a related field.
- Demonstrated experience in deploying AI solutions into production environments.
What We Offer
- Meaningful AI Work: Build practical AI solutions designed for real enterprise environments and measurable business impact.
- End-to-End Ownership: Contribute across architecture, development, deployment, evaluation, and ongoing optimisation.
- Technical Influence: Help shape engineering standards, architectural decisions, and the continued development of Quantanite’s AI capabilities.
- Modern AI Challenges: Work with multi-agent systems, advanced retrieval, LLM optimisation, and production AI engineering.
- Global Exposure: Collaborate with technical and business teams across an international organisation operating on four continents.
- Career Development: Grow your technical leadership capability while mentoring engineers and contributing to a developing AI function.
- Work Model: Hybrid role based in Mumbai, India.
- Culture: A fast-moving, collaborative, and inclusive environment where strong ideas, accountability, and practical outcomes are valued.
