In this role, you will build the intelligent systems and AI powered capabilities that enable customers in fast moving, data rich industries to operate, scale, and innovate. You will develop robust, production ready AI solutions that harness automation, advanced analytics, and machine learning to power real time decision making across complex digital transformation programmes. With access to cutting edge AI frameworks, high performance compute, and modern data platforms, you will work closely with architects and data scientists to engineer secure, scalable, and ethical AI applications. This role empowers you to bring end to end AI ecosystems to life—accelerating delivery, enhancing customer experiences, strengthening operational resilience, and helping organizations realise the full potential of an AI enabled future.

Key Responsibilities

  • Build and ship production ready AI/ML features—from data ingestion and feature engineering to model training, evaluation, and deployment.
  • Develop LLM/GenAI solutions (prompt engineering, tool use, guardrails) and RAG pipelines (chunking, embeddings, vector search, caching, re ranking).
  • Optimise training and inference performance via batching, quantisation, distillation, LoRA/PEFT, accelerator utilization (GPU/TPU), and efficient memory/latency tuning.
  • Build and maintain MLOps/LLMOps workflows—CI/CD for models and prompts, model registry/versioning, feature stores, and automated promotion across environments.
  • Instrument observability for data, models, and prompts (telemetry, metrics, traces, dashboards, alerts); implement A/B tests and online/offline evaluation.
  • Embed Responsible AI considerations (fairness, explainability, safety, bias testing) and document assumptions, datasets, and limitations.
  • Document architecture, workflows, and best practices to support scalability and ongoing maintainability.
  • Conduct code reviews, write unit/integration/e2e tests (including data and prompt tests), and uphold engineering standards and documentation.
  • Work with advanced AI/ML frameworks, cloud services, and container orchestration platforms.

As an AI Engineer, you are responsible for designing, building, and deploying scalable AI and machine learning solutions that solve real-world business problems, partnering closely with data scientists to productionize models and integrate them seamlessly into applications and enterprise workflows.

Your Profile

  • AI Engineer (5 to 12 Years).
  • Hands‑on experience with GenAI, Gemini or Open source LLMs, Train, finetune and Onboard new LLMs.
  • Experience in building GenAI applications using Python.
  • Hands‑on Experience with API Development and Microservices architecture and End to End integrations.
  • Knowledge of RAG (Retrieval-Augmented Generation) and ADK, MCP.
  • Solid understanding of LLMs, prompt engineering, and graph-based workflows.
  • Experience in CI/CD pipelines, and containerization (Docker/Kubernetes), Harness and Git actions.
  • Practical experience implementing LLM and GenAI solutions, including prompt engineering, model fine tuning, RAG pipelines, embeddings, and vector databases.
  • Build scalable data pipelines and workflows on GCP (Big Query, Vertex AI, Dataflow, Pub/Sub, Redis and NoSQL Databases, Maintaining chat history etc.).
  • Optimize model performance, monitor production systems, and ensure reliability, Auto Scaling using Prometheus, Dynatrace and Lang Smith.
  • Strong hands on experience building and deploying machine learning models, including preprocessing, feature engineering, training, evaluation, and optimization.
  • Knowledge of API Gateways and ISTIO, ability to Diagnose and intercept failures in End to End communication.
  • Implement best practices for data governance, security, and MLOps on GCP.
  • Proficiency with Python and common AI/ML frameworks such as TensorFlow, PyTorch, JAX, scikit learn, and Hugging Face libraries.
  • Knowledge of MLOps and LLMOps practices—including CI/CD for models, model registry/versioning, feature stores, orchestration, and automated deployments.
  • Ensure AI solutions meet security, privacy, compliance, and responsible AI standards.
  • Understanding of secure engineering and data protection practices, including IAM, secrets management, encryption, and safe handling of sensitive data.
  • Ability to optimise performance of training and inference pipelines—profiling, quantisation, distillation, batching, caching, or hardware acceleration.
  • Collaborate with data scientists to productionize models and integrate them into applications, workflows, and APIs.
