The Applied ML Engineer (Gen AI) plays a foundational role in establishing and scaling the organization’s AI infrastructure and knowledge systems. This position focuses on building robust LLM deployment pipelines, retrieval-augmented generation (RAG) systems, embedding / tokenization workflows, and integrating AI agents into internal tools. The engineer will collaborate across teams to develop production-ready Gen AI applications and enable internal innovation at scale. The ideal candidate combines technical depth in machine learning operations with creativity in applying AI to real-world business contexts as well as a strong background in software engineering. How You’ll Make An Impact

LLM Infrastructure & Evaluation

Deploy, manage, and monitor Large Language Models (LLMs) such as LLaMA, GPT, Mistral, and Claude. Build internal evaluation pipelines to benchmark model performance across diverse business use cases. Knowledge Systems Development

Design and implement advanced RAG pipelines using vector databases like Pinecone or Weaviate. Develop graph-powered knowledge systems using Neo4j, ArangoDB, or TigerGraph. Create scalable chunking and tokenization strategies for semantic search and document ingestion. Embedding, Tokenization & Retrieval Optimization

Select and apply embedding models (OpenAI, Cohere, HuggingFace) for downstream tasks. Optimize chunking and retrieval pipelines for low-latency, high-recall performance. Engineer dynamic context windows for multi-turn conversations and long-form reasoning. Agentic Workflows & Tooling Integration

Build autonomous workflows using LangChain, Haystack, AutoGen, or CrewAI. Integrate LLM tools into internal platforms (e.g., task bots, report generators, coding copilots). Automate tool use via Function Calling APIs and connect agents to knowledge graphs. MLOps Core & Deployment

Build CI / CD pipelines for data workflows, LLM retraining, and production rollout. Manage containerized environments using Docker, Kubernetes, or Kubeflow. Implement monitoring, alerting, and logging for Gen AI systems in production. Experimentation & Internal Enablement

Lead experiments and PoCs to evaluate new LLM use cases (chatbots, assistants, research agents). Collaborate with backend, data, and QA teams to scale AI solutions company-wide. Create reusable AI modules to support operational teams (e.g. Compliance, Finance, Payouts). What You Bring

Bachelor’s degree in Computer Science, AI, Data Engineering, or related field. Minimum 7 years of experience in relevant fields with 2+ years of experience in Machine Learning, MLOps, or AI infrastructure Proficiency in deploying and optimizing LLMs and vector databases. Hands-on experience with LangChain, LlamaIndex, or similar frameworks. Strong understanding of tokenization, embeddings, and prompt engineering. Experience with graph databases (e.g., Neo4j, ArangoDB) and query languages (Cypher, GraphQL). Familiarity with fine-tuning methods (LoRA, QLoRA) and feedback loops. Containerization and orchestration experience with Docker / Kubernetes. Team mindset, adaptability, and eagerness to solve complex problems in novel ways. Your X-Factor

Designs AI infrastructure that’s production-ready, not just experimental. Automates LLM workflows using scripting and orchestration frameworks. Balances innovation with maintainability in a fast-scaling environment. Identifies opportunities to embed AI into core business operations. Bridges technical depth with clear communication and business alignment. Your Pay & Perks

Salary Range : Competitive Pay Bi-annual Salary Review (eligibility condition applies). Festival bonus (eligibility condition applies). Celebrate with birthday leaves and great team events. Unwind together at annual company retreats. Kick back with game nights and all-access sports zones – billiards, foosball, PlayStation, cricket, football & badminton. Get moving with an in-house fitness trainer to keep your mind and body in sync. Start the next chapter in your life, with our special honeymoon package. Opportunities for relocation to Sri Lanka and Malaysia, subject to business needs, with travel allowances. Your Journey after Applying
