• Develop end-to-end GenAI features including backend API services, model integration, model monitoring, evaluations and deployments

• Integrate and optimize LLMs for specific use cases in business planning, including prompt engineering, RAG implementation

• Build conversational interfaces and agentic workflows that make complex planning tasks accessible through natural language

• Implement evaluation frameworks to measure and improve GenAI feature quality, including accuracy, latency, and user satisfaction metrics

• Design and develop APIs that expose AI capabilities to Anaplan’s platform and third-party integrations

• Optimize model inference pipelines for performance, cost, and scalability in production environments

• Implement monitoring, logging, and observability for GenAI systems to track usage, errors, and model behaviour

• Collaborate with data scientists to productionize ML models and forecasting algorithms

• Write comprehensive tests including unit tests, integration tests, and prompt regression suites

• Participate in code reviews, technical design discussions, and knowledge-sharing sessions

• Stay current with GenAI research and tools, evaluating new models and techniques for potential adoption

Requirements

• 4+ years of software engineering experience with 2+ years focused on ML/AI systems

• Strong programming skills in Python including experience with ML frameworks (PyTorch, TensorFlow, Transformers)

• Experience building and deploying LLM-powered applications in production

• Proficiency in front-end development with React, TypeScript, and modern web technologies

• Understanding of RESTful API design, microservices architecture, and cloud infrastructure

• Experience with prompt engineering, RAG systems

• Strong foundation in ML fundamentals including NLP, time-series analysis, or recommender systems

• Familiarity with containerization (Docker), orchestration (Kubernetes), and CI/CD pipelines

• Excellent problem-solving skills and attention to detail

• Bachelor’s degree in computer science, Machine Learning, or related field

Nice to have skills:

• Experience with GenAI frameworks (LangChain, LlamaIndex, Haystack, or similar)

• Knowledge of vector databases (Pinecone, Weaviate, Qdrant) and embedding models

• Experience with model serving frameworks (vLLM, TensorRT, Ray)

• Background in forecasting, planning, or analytics applications

• Familiarity with Anaplan or similar enterprise planning platforms

• Experience with A/B testing and experimentation frameworks for AI features

• Contributions to open-source ML projects or research publications

• Experience with model observability tools (LangSmith, W&B, MLflow)

What we offer

• Hybrid/flexible working model and flexible working hours

• Private Medical and/or Health Insurance (location dependent)
