Senior Gen Ai Engineer

 

Description:

We're seeking a versatile Senior Gen AI Engineer who can work across the full stack of GenAI applications, from model integration and prompt engineering to building intuitive user interfaces. You'll build production-ready AI features that empower business users to leverage the power of GenAI within their planning workflows, requiring both deep ML knowledge and strong software engineering skills.

Your Impact

  • 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 and 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

Your Qualifications

  • Software engineering experience with a focus 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

Preferred Qualifications

  • 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 Makes This Role Exciting

  • Lead a greenfield team building transformative AI capabilities from the ground up
  • Work on cutting-edge conversational and agentic AI technologies
  • Build user-facing AI features that directly impact how businesses plan and make decisions
  • Experiment with the latest GenAI models and techniques
  • Collaborate with talented engineers, data scientists, and product designers
  • Solve unique challenges at the intersection of AI and enterprise software
  • Grow your skills in both ML engineering and full-stack development
