AI Engineer (Engenheiro de IA) São Paulo (Remote)

Ready to accelerate your career

CLARAs Innovation Team is looking for a pragmatic fast-moving AIEngineer who thrives on shipping AI-powered features quickly. This team operates in ultra-fast mode identifying opportunities building prototypes and delivering production-ready AI solutions that create immediate business value. Youll work at the intersection of product engineering and AIturning ideas into deployed features in weeks not months.

Responsibilities

Your main focus will be to rapidly build and ship AI features that solve real customer and internal problems. Youll own projects end-to-end: from scoping and architecture to implementation and production deployment. Speed and pragmatism are core to this roleyoull make smart tradeoffs to deliver quick wins while maintaining production quality standards.

Core Responsibilities:

Rapid AI Product Development

• Design build and deploy AI-powered features and applications from 0 to 1 in production
• Integrate LLMs and AI models into existing products and workflows handling the full stack from API integration to user-facing features
• Build intelligent automation tools that improve internal operations customer experience or business processes
• Create MVPs and prototypes quickly to validate ideas then iterate based on real usage and feedback
• Own the entire lifecycle: scoping technical design implementation deployment and monitoring

Production Engineering & Infrastructure

• Build robust APIs and backend services that power AI features with proper authentication rate limiting and error handling
• Design and implement data pipelines that support AI applications: document processing embedding generation vector search
• Deploy and maintain containerized applications on AWS infrastructure (ECS Lambda S3 RDS)
• Implement monitoring logging and observability for AI features in production
• Ensure AI applications meet security privacy and compliance requirements for financial services

Cross-Functional Collaboration & Innovation

• Work closely with product teams data scientists and business stakeholders to identify high-impact AI opportunities
• Translate business problems into technical solutions making pragmatic decisions about build vs. buy vs. API
• Share knowledge and evangelize successful patterns across engineering teams
• Balance speed with sustainabilityship fast without creating technical debt that blocks future iteration
• Contribute to the broader engineering organization by bringing innovation team learnings back to core teams

Continuous Learning & Experimentation

• Stay current with rapidly evolving AI tools frameworks and best practices
• Experiment with new AI capabilities and evaluate their potential for Claras use cases
• Share findings demos and insights with the broader team to inspire innovation

Requirements

Technical Skills:

• Strong proficiency in Python; working knowledge of or Java
• Hands-on experience integrating LLMs into production applications (not just prompt engineering)youve built real features with OpenAI Anthropic or similar APIs
• Database expertise: PostgreSQL vector databases (Pinecone Weaviate Chroma pgvector) or data modeling
• Cloud infrastructure: AWS services (ECS S3 Lambda RDS API Gateway SQS etc.)
• API development: RESTful services authentication rate limiting error handling

Experience:

• Built and deployed at least 2 AI/ML features or products to production that real users interact with
• Experience with containerization (Docker) and orchestration (ECS EKS or similar)
• Comfortable with git workflows and CI/CD practices (GitHub Actions GitLab CI automated deployments)
• Experience working across the full stack: backend APIs data processing and basic frontend integration

Mindset:

• Problem-solver first technology evangelist secondyou choose the right tool for the job not the newest one
• Comfortable with ambiguity and rapid iterationyou thrive when requirements are fuzzy and priorities shift
• Self-directed with ability to scope and execute projects independentlyyou can take a problem and run with it
• Bias toward actionyou ship working solutions and iterate based on feedback rather than pursuing perfection

Nice to Have

• Experience with LangChain LlamaIndex or similar LLM frameworks for building RAG applications
• Familiarity with embedding models and semantic search implementations
• Experience with streaming APIs and real-time AI applications (WebSockets Server-Sent Events)
• Frontend experience (React ) to build full-stack AI features
• Knowledge of ML model deployment (model serving inference optimization A/B testing)
• Experience in fintech or highly regulated industries understanding compliance and security requirements
• Background in data engineering or analytics to understand data pipelines and infrastructure
• Experience with prompt engineering best practices and LLM evaluation frameworks
• Contributions to open-source AI/ML projects or technical writing/blogging

What Makes You Stand Out

Execution & Velocity

• You have a track record of shipping fastyour GitHub/portfolio shows completed projects not abandoned experiments
• Youre comfortable making technical tradeoffs to hit timelines without sacrificing quality
• You know when to build custom solutions vs. when to use managed services or third-party APIs
• You can scope projects realistically and communicate progress transparently

Technical Depth & Pragmatism

• You understand the full lifecycle of AI features: prompt engineering API integration error handling cost optimization monitoring
• Youve debugged production issues with LLM-powered applications and know the common pitfalls
• Youre proficient with modern development tools and AI assistants (GitHub Copilot Cursor Claude ChatGPT) to accelerate your work
• You write clean maintainable code that others can understand and extend

Innovation & Business Sense

• You think about business impact not just cool technologyyou ask will this move the needle before building
• Youre curious and stay current with AI developments but youre skeptical about hype
• You enjoy working directly with stakeholders to understand problems and validate solutions
• Youre energized by ambiguity and the challenge of building something new

Collaboration & Communication

• Excellent at working in distributed teams with strong communication skills
• You can explain technical concepts to non-technical stakeholders clearly
• You take ownership of outcomes not just codeyou care about whether users get value from what you build
• Youre humble eager to learn and willing to help others succeed

Claras Hybrid Policy

Claridians in a hybrid mode split their time between working from the office talking to or visiting customers or working from home. This hits a balance between bringing people together for in-person collaboration and learning from each other while supporting flexibility about how to do this in a way that makes sense for each individual and team.

We dont enforce a minimum number of days for most roles but youre expected to spend time at the office organically and be at the office most days during your ramp-up or when required by your leader.
