• Serve as a senior team member contributing to and helping guide the delivery of high quality software products. • Assume ownership and responsibility of all work, and drive it to completion. • Collaborate with technical and non-technical team members to ensure rapid delivery of software products. • Provide contributions to architecture and design decisions that have a major impact on the overall system scalability and performance. • Champion software engineering best practices, including code reviews, testing, documentation, and code quality standards. • Lead by example, demonstrating a commitment to excellence, professionalism, and collaboration in all aspects of software development and team interactions.

• Build and maintain a full stack web application using React • Develop and integrate REST APIs, webhooks, and third party services such as Stripe • Design and manage PostgreSQL databases • Implement secure authentication and authorization systems • Ensure high performance for live, transaction based applications • Sync data seamlessly between web and mobile platforms • Maintain strong security practices around financial and sensitive user data • Collaborate in a startup environment with a small, fast moving team

• Projetar e implementar **produtos e sistemas fullstack** voltados à alavancagem de crescimento (ex: landing pages dinâmicas, automações de aquisição, ferramentas para vendas internas e CRM, experimentos A/B). • Trabalhar **lado a lado com stakeholders internos** (Growth, Data, Marketing, CX, Produto) para identificar oportunidades técnicas com impacto direto no funil de vendas. • Construir e manter **sistemas distribuídos**, integrando serviços internos e APIs externas com confiabilidade e performance. • Ser **referência técnica para o time**: tomar decisões de arquitetura, revisar PRs, compartilhar boas práticas e manter um código limpo e sustentável. • Conduzir iniciativas do zero com autonomia, priorizando problemas de maior impacto e mensurando resultados com clareza. • Manter alto padrão de engenharia: **testes automatizados, observabilidade, documentação, performance, segurança e resiliência**. • **Construir monitoramento e alertas**, participar de escalas de **on-call** e atuar na resposta a incidentes, com foco em aprendizado e melhoria contínua.

• Design & Build AI-Powered Features: Architect, implement, and ship data-driven product features, always starting with the customer problem first. From prototyping through production, you’ll apply the right level of technology (whether simple heuristics or advanced AI) to deliver impact. • Build for Production: Build maintainable and scalable systems, including writing clean, testable code, integrating with new and existing data pipelines, and deploying solutions and services into cloud environments. • End to End Solution Delivery: Operate as an end-to-end developer in a fast paced startup. This involves identifying opportunities, prototyping solutions, securing stakeholder support, and productionalizing features that deliver measurable business value. • Applied AI Innovation: Research and apply modern methods (AI agents, LLMs, RAG, embeddings, supervised/unsupervised learning) to power new product capabilities, prioritizing impact and speed over perfection. • Enhance User Experience Through AI: Translate business problems into AI solutions that improve user workflows, accelerate insights, and drive measurable value. • Collaborate Cross-Functionally: Work with business stakeholders and other engineers to turn customer problems into technical requirements and impactful features. • Promote Best Practices: Establish and evangelize standards for AI/ML engineering and data quality across the team.
