About the client

Our client is a leading global consulting firm that delivers transformation programs for companies worldwide. They develop internal tools and client-facing web applications using modern full-stack development and Generative AI, focusing on automation, smarter decision‑making, and enhanced user experiences.

About the role

We’re hiring Full‑Stack Engineers (Python/React/GenAI) to join multiple production AI initiatives. You will collaborate with a multidisciplinary consulting team to build scalable web applications and integrate GenAI capabilities into business workflows.

This role is a great fit for engineers who like owning features end‑to‑end, collaborating with stakeholders, and shipping in a fast‑moving environment. It’s also important to note: general full‑stack experience alone isn’t enough. You’ll be expected to contribute both to new builds from scratch and to improving and expanding existing systems — including integrating GenAI features that will be used in production.

What success looks like

• Ship production‑grade features end‑to‑end using Python (Django preferred) and React, including well‑structured APIs and reliable deployments.

• Deliver GenAI features in production (LLM interactions, workflow automation, data enrichment, RAG) with practical guardrails and evaluation.

• Improve performance and maintainability by identifying bottlenecks, strengthening service boundaries, and contributing to CI/CD quality.

• Collaborate effectively with distributed, cross‑functional teams across multiple initiatives and geographies.

Responsibilities

• Develop, maintain, and optimize backend services using Python (Django preferred; Flask/FastAPI acceptable).

• Build responsive, maintainable front‑end interfaces using React.

• Integrate Generative AI capabilities into existing and new applications (e.g., LLM interactions, workflow automation, data enrichment, RAG).

• Design and implement REST APIs that connect front‑end, back‑end, and AI services.

• Assist in testing, debugging, and deployment using modern CI/CD practices.

• Collaborate with stakeholders to translate requirements into scalable, production‑ready solutions.

Must have

• Experience of at least 3 years in the domain.

• Solid hands‑on understanding of Python (Django/Flask/FastAPI or similar).

• High level of front‑end familiarity with React (production web apps).

• Hands‑on experience building or integrating GenAI solutions in production (OpenAI/Azure OpenAI, LangChain, embeddings, vector DB, RAG).

• Master the fundamentals of RESTful API/Service integration design.

• Experience with databases: SQL and/or NoSQL.

• Knowledge of cloud environments: AWS, Azure, or GCP.

Nice to have

• Knowledge of MLOps workflows (model evaluation, monitoring, prompt/versioning, deployment patterns).

• Experience in consulting or enterprise settings.

Important to note

• Location: Brazil‑based candidates ONLY (São Paulo & Rio areas)

• Work model: Remote, with expected onsite visits a few times per month.

• Type: Contract, 40h/week.

• Duration: 6‑12 months initially, with long‑term engagement.

• Authorization: Applicants must be authorized to work in their country of residence without employer sponsorship.

Why consider this opportunity

• You’ll get access to Toptal’s global network, including opportunities with Fortune 500 and other enterprise clients.

• You’ll have flexibility to choose projects that match your goals — part‑time or full‑time, short‑term or long‑term (based on matching and availability).

• There’s a potential path to direct employment with the client later.

• The client may provide a Windows laptop.
