Azumo builds and operates production AI systems for companies ranging from seed-stage startups to Meta. We are hiring an AI Engineer to own what those systems do once they are live: retrieval pipelines, tool-using agents, evaluation harnesses, and the guardrails that keep them dependable in front of real users. The role is fully remote across Latin America, aligned to your client's working day. You will not be building demos. Azumo has shipped production AI since 2016, and the work here starts where the prototype ends, making a system reliable, measurable, and affordable enough to put in front of customers. Where this role sits Azumo's engineering organization is built around four lanes. The Data Engineer lane owns pipelines, storage, and the retrieval layer. The Data Scientist lane owns the question and the method. The Software Engineer lane owns AI-augmented product delivery. This role is the AI Engineer lane, and it owns production behavior. One question places the boundary: when the output is wrong, whose problem is it? "The method was inappropriate" is a Data Scientist question. "The system did the wrong thing with an appropriate method" is yours. Not quite

- Retrieval systems. Chunking and embedding pipelines, hybrid search, reranking, and evaluation of retrieval quality, built on pgvector, Pinecone, Qdrant, FAISS, or Azure AI Search.
- Agentic workflows. Stateful multi-step execution, tool calling,



MCP servers, structured output enforcement, context-window management, deterministic fallbacks, and human-in-the-loop gates for the decisions that need one.
- Evaluation. Test sets that reflect the decision the system is actually making, model-as-judge scoring, regression tracking across prompt and model changes, and honest error analysis. If a change made the system better, you should be able to prove it.
- Reliability and safety. Prompt-injection defense, output validation, guardrails, PII handling, and graceful degradation when a model or tool call fails.
- Production operation. Containerized deployment on Azure or AWS, CI/CD, observability, and explicit latency, cost, and token budgets that you own rather than discover after the invoice.
- Work inside the client's environment. Their repositories, their standups, sometimes their customer calls. Azumo is SOC 2 certified, client code stays in client repositories, and some engagements carry additional requirements such as HIPAA. How we work Our engineers build with AI every day. Claude Code, Codex, and similar tools are part of the standard toolchain here, not an experiment. We run an automated audit across the whole codebase on day one and every day after, grading security, cost, and architecture findings by severity with the exact file and line, so a small team can move quickly without quality drifting. We stay vendor-neutral across OpenAI, Anthropic,



and open-weight models, and we run Valkyrie, our own production layer, when a single interface to any model is the right call. About Azumo Azumo is a San Francisco based software development company that has been building intelligent applications since 2016. We provide nearshore AI engineering teams to organizations that need production AI faster than they can hire for it: as an embedded engineering team, as AI staff augmentation alongside an existing team, or as a full project build. Our engineers work from Latin America, aligned to United States time zones, and have delivered for Twitter, Meta, Discovery Channel, Omnicom, UnitedHealth, and CENTEGIX. We hire for seniority and test for it before anyone joins a client team. We support engineers in going deep on the modern AI stack, and we give time back to open-source work, community teaching, and philanthropy. Apply at https://azumo.com/join-our-team or write to us at [email protected]. Requirements Basic qualifications
- 4+ years building and shipping production software, with a modern backend language (e.g., Python) as your primary focus, plus the engineering fundamentals that go with it: testing, code review, CI/CD, Git, containers, API design, and async programming.
- Demonstrable production experience with LLM-based systems: retrieval-augmented generation, function and tool calling, structured output enforcement, and prompt design as an engineering discipline rather than trial and error.
- Hands-on work with vector and retrieval infrastructure such as pgvector, Pinecone, Qdrant, FAISS, or Azure AI Search, including the retrieval-quality problems that come with it.
- Experience with agent frameworks and tooling: LangGraph, LangChain, CrewAI,
