AI/ML Engineer

We're looking for an AI/ML Engineer to design, build, and deploy machine learning systems and intelligent agentic solutions that solve real business problems. This role is centered on agentic AI - building LLM-powered systems that can reason, plan, and autonomously take action across multiple AI platforms and ecosystems - combined with classic ML engineering across the full lifecycle, from data pipelines and model development to production deployment. You'll work closely with our AI Platform Architect to align implementation with technical strategy and architecture standards, and partner directly with business stakeholders to ensure the solutions you build translate into real operational impact.

Applied Engineering

Collaboration & Communication

• Bachelor's or master's degree in computer science, Machine Learning, or related field (or equivalent experience)
• 5+ years of experience building and deploying ML models in production
• Strong programming skills in Python; familiarity with ML frameworks (PyTorch, TensorFlow, scikit-learn)
• Hands-on experience building and deploying agents on at least one major AI platform (e.g., Azure AI Foundry, Google Vertex AI / Gemini, Anthropic Claude), with strong interst in working across multiple
• Experience with LLM APIs and prompt engineering across providers (OpenAI, Anthropic, Google)
• Familiarity with vector databases and RAG architectures (e.g., Pinecone, Weaviate, Chroma)
• Experience with computer vision or image recognition models in a production setting
• Solid understanding of software engineering fundamentals: version control, testing, API design
• Experience with cloud platforms (AWS, GCP, or Azure)
• Experience building agents on Azure AI Foundry (Agent Service) and/or Google Vertex AI Agent Builder
• Familiarity with cross-platform agent portability - adapting the same agent logic/tooling across different model providers and orchestration layers
• Experience with multi-agent orchestration frameworks (LangGraph, AutoGen, CrewAI)
• Experience designing agentic systems that combine perception (vision/detection) outputs with reasoning/action layers
• Background in reinforcement learning or fine-tuning LLMs (LoRA, RLHF)
• Experience with containerization and orchestration (Docker, Kubernetes)
• Contributions to open-source ML/AI projects
• Familiarity with evaluation frameworks for LLM/agent outputs
• Experience optimizing models for on-device or edge deployment (e.g., mobile/tablet applications)
