Senior Machine Learning Engineer

• Building and maintaining agentic workflows that read customer data, make decisions, and take real actions (refunds, order updates, escalations, and similar)
• Writing, testing, and refining prompts, including thinking through where a model is likely to hallucinate or get overconfident, and designing around it
• Building and scaling backend endpoints (using FastAPI, Flask, or Django) that serve these AI systems reliably in production, not just in a notebook
• Working with retrieval systems (RAG), embeddings, and vector search to ground responses in real data instead of the model's memory
• Reviewing and improving existing automations built in n8n, and helping decide when something should move from a no code workflow into real code
• Digging into a wrong or weird agent output, tracing it back through logs and executions, and fixing the actual root cause
• Staying current enough with the field that you naturally bring up a new model release, a new benchmark, or a new coding tool without being asked

• Solid hands on experience with agentic AI concepts: tool calling, multi step reasoning, memory, and orchestrating more than one agent to solve a problem
• Practical experience with at least one agent framework such as LangChain, LangGraph, CrewAI, AutoGen, or the OpenAI or Anthropic agent/assistant SDKs. We care more that you understand the concepts underneath than which specific framework you have used
• Real backend development experience in Python, with a framework such as FastAPI, Flask, or Django, including designing and deploying an API that other systems actually call
• A working understanding of NLP and how LLMs behave: context windows, tokens, embeddings, fine tuning versus retrieval, and why a model says confident things that are wrong
• Comfort with prompt engineering as an actual practice, not guesswork: iterating on a prompt, testing it against real cases, and knowing when the fix belongs in the prompt versus in the code around it
• A genuine foundation in data science and machine learning: you should be able to talk through a basic model training and evaluation workflow, know why accuracy is often the wrong metric, and be comfortable with Python's data stack (pandas, NumPy, scikit-learn)
• At least one real project, professional or personal, that touches this space. We would rather see one thing you built end to end than a long list of tools you have briefly touched
• Genuine curiosity about the field. You should already be someone who reads about new model releases, checks benchmark leaderboards, and tries out new AI coding tools on your own, not because a job requires it

• Experience with n8n, Zapier, or Make.com. Several of our internal systems are built this way, and being able to read, debug, or improve one of these workflows is genuinely useful, even though it is not the core of this role
• Experience with vector databases such as Pinecone, Weaviate, Chroma, or pgvector
• Familiarity with Postman or similar tools for API testing
• Exposure to MongoDB or PostgreSQL
• Experience using AI coding assistants day to day, such as Claude Code, GitHub Copilot, or Cursor
