AI Systems Engineer (Chatbots)

Xpedeon; Mumbai; Presencial; INR 1.800.000 - 3.200.000; Tempo integral

Resumo da vaga

Xpedeon America, Inc. seeks a software engineer to design and build scalable AI agent pipelines that convert natural-language questions into governed answers over structured data. You will implement multi-step logic, retrieval, validation, and state management for production use.

The role emphasizes reliability, safety, and scalability, with testing and regression suites, and collaboration with frontend and data teams to ground the system in real business rules.

Qualificações

• 3+ years of professional software engineering experience, with strong proficiency in Python.
• Hands‑on experience building applications on top of large language models and multi‑step logic.
• Experience with retrieval‑augmented generation or vector/embedding‑based search.
• Strong SQL skills and comfort reasoning about data access, correctness, and security boundaries.
• Solid testing practices including unit testing and regression suites for non‑deterministic components.
• Experience designing clean interfaces between components in a service/pipeline.

Responsabilidades

• Design and build multi‑step agent pipelines that combine LLM calls with deterministic logic.
• Implement retrieval‑augmented generation with embedding search that scales.
• Build safeguards around model outputs with validation and constraints.
• Design for ambiguity and handle clarifications or safe defaults.
• Own session/state management for coherent multi‑turn interactions.
• Write automated regression tests and golden test sets.
• Extend system to new use cases via configuration rather than rewrites.
• Collaborate with frontend, data, and product to ground rules and data access.

Descrição da vaga

About the role

We're building an agentic AI system that turns natural-language questions into accurate, governed answers over structured business data. This isn't a thin wrapper around a chat API — it's a multi-stage pipeline with retrieval, guardrails, and session state, and we need someone who can design and build that scaffolding, not just prompt a model well. You'll work on the reliability, safety, and scalability of an AI agent used in production by real customers.

What you'll do

• Design and build multi-step agent pipelines that combine LLM calls with deterministic logic — retrieval, validation, and business rules — rather than relying on a single prompt to do everything.
• Implement retrieval-augmented generation (RAG): embedding-based search, ranking, and context assembly that stays within token/latency budgets as the underlying knowledge base grows.
• Build safeguards around model output — validating, sanitizing, and constraining what the AI is allowed to do or return before it reaches a user or a downstream system.
• Design for ambiguity: detect when a user's request is underspecified and decide whether to ask a clarifying question, apply a documented default, or refuse — rather than having the system silently guess.
• Own session and conversation state so multi-turn interactions stay coherent across follow-up questions.
• Write automated regression tests for AI-driven behavior, including "golden" test sets that catch quality regressions a human might not notice by eyeballing a few responses.
• Extend the system to new use cases/domains through configuration rather than one-off code, so growth doesn't multiply maintenance burden.
• Collaborate with frontend, data, and product stakeholders to ground the system in real business rules and correct data access boundaries.
• Instrument and monitor the pipeline in production — latency, cost, failure modes, and answer quality over time.

Required qualifications

• 3+ years of professional software engineering experience, with strong proficiency in Python (or a comparable backend language).
• Hands‑on experience building applications on top of large language models — not just calling a chat API, but designing multi‑step logic, structured outputs, and validation around it.
• Experience with retrieval‑augmented generation or vector/embedding‑based search.
• Strong SQL skills and comfort reasoning about data access, correctness, and security boundaries.
• Solid testing practices — unit testing, mocking external dependencies, and building regression suites for systems with non‑deterministic components.
• Experience designing clean interfaces/contracts between components in a service or pipeline, so systems stay maintainable as they grow.
• Clear written communication — comfortable documenting assumptions and design decisions rather than guessing silently on ambiguous requirements.

Preferred qualifications

• Experience with a major LLM provider platform (Google Vertex AI/Gemini, OpenAI, AWS Bedrock, Azure OpenAI, or Anthropic).
• Experience building a natural‑language‑to‑SQL or natural‑language‑to‑structured‑query system specifically.
• Familiarity with cloud deployment (GCP, AWS, or Azure) and containerization (Docker).
• Experience with session/cache stores (e.g., Redis) for stateful, multi‑turn systems.
• Frontend familiarity (React/Next.js/TypeScript) sufficient to collaborate across the stack.
• Domain experience in financial, ERP, or B2B analytics data.

What we're explicitly not looking for

Deep ML research or model‑training expertise — this role is about building robust systems around a foundation model API, not training models.

Pure prompt‑engineering/no‑code AI experience without underlying software engineering skill.

Success in the first 90 days

• Ship at least one end‑to‑end pipeline component (retrieval, validation, or state management) into production use.
• Contribute a test suite that catches a real quality or safety regression before it reaches users.
• Help onboard a new use case/data domain into the system, proving it can extend without a full rewrite.
