Overview of the role:
As a Staff AI Engineer in Flutter Brazil’s AI Core Team, you will help define how Generative AI is designed, built, and operated across our products.You will be a hands-on technical leader responsible for evolving our GenAI Platform, the platform that enables teams to build, evaluate, deploy, and operate AI applications and agents at scale. You will also help turn these capabilities into customer-facing experiences used across Flutter Brazil’s products.
This role is for an experienced engineer who has already taken GenAI systems beyond prototypes and understands the challenges of operating them in production: evaluation, reliability, latency, cost, safety, observability, and continuous improvement.You will work across Product, Engineering, Platform, Data, and Security, leading complex technical initiatives and shaping the foundations of our AI ecosystem.
What you’ll do:
- Define and evolve the architecture of our GenAI Platform and its core platform capabilities.
- Build and operate production-grade GenAI applications, agents, and customer-facing experiences.
- Design model-agnostic systems using commercial and open-source models from multiple providers.
- Build capabilities for model routing, tool use, retrieval, memory, evaluation, guardrails, and observability.
- Design reliable agentic workflows that combine LLMs, deterministic systems, business rules, and human oversight.
- Solve complex production challenges involving quality, latency, availability, scalability, and cost.
- Establish evaluation frameworks and use production data and experimentation to continuously improve AI systems.
- Develop reusable services, APIs, and engineering patterns that accelerate AI adoption across teams.
- Lead architecture discussions, influence technical strategy, and mentor senior engineers.
- Partner with Product teams to translate AI capabilities into measurable customer and business outcomes.
What you’ll bring:
- Deep software engineering experience, with a strong track record of designing and operating complex production systems.
- Proven experience taking GenAI applications from concept to production at meaningful scale.
- Strong understanding of LLMs, agentic systems, tool use, structured outputs, context management, and common failure modes.
- Experience designing evaluation strategies for non-deterministic systems.
- Experience with retrieval systems, including RAG, semantic search, embeddings, and hybrid retrieval.
- Strong system design fundamentals, including distributed systems, APIs, backend services, and resilient architectures.
- Proficiency with Python and modern software engineering practices.
- Experience with cloud infrastructure, preferably AWS.
- Ability to make pragmatic trade-offs between model quality, latency, reliability, safety, and cost.
- Ability to lead through technical influence while remaining deeply hands-on.
- Strong communication skills and the ability to work effectively across engineering, product, and business teams.
- Intermediate English proficiency and fluency in Portuguese.
Nice to have:
- Experience building AI assistants, copilots, agents, or conversational products used by external customers.
- Experience with MCP, agent orchestration frameworks, or multi-agent architectures.
- Experience building model gateways, model-routing systems, or multi-provider AI platforms.
- Experience with automated LLM evaluation, online experimentation, and human-in-the-loop systems.
- Experience building AI products in regulated, high-scale, or consumer-facing environments.
- Experience working with both proprietary and open-source models.
- Contributions to open-source AI projects or active participation in the AI Engineering community.
This is an opportunity to become a foundational member of Flutter Brazil’s AI Core Team.You will not be building isolated prototypes. You will help define the architecture, platform, and engineering standards that enable AI-powered experiences to reach millions of customers. 🚀
Benefits:
- Competitive compensation
- Access to TotalPass
- Paid time off
- Remote environment
- Individual development allowance
- Allowance allocated for language courses or classes
- Growth and learning opportunities through the Flutter Edge global network and more.
