• Serve as the company's primary technical authority • Work hands-on in the development of the platform • Define architecture, engineering standards, and technical direction • Lead decisions on scalability, integration, and system reliability • Partner with Product to define solutions and priorities • Work closely with the Data team to ensure consistency, availability, and data quality • Structure the technical roadmap and prioritize technical debt • Evolve development processes, quality practices, and engineering best practices • Ensure information security, governance, and compliance with LGPD • Actively participate in the company's strategic discussions

• Design, develop, and maintain scalable, reliable, and efficient full-stack applications using ReactJS, NodeJS, NestJS, MongoDB, and PostgreSQL; • Work with cloud platforms (AWS, GCP, or Azure); • Apply software engineering best practices (SOLID, Clean Code); • Collaborate with teams to implement SaaS solutions and digital platforms; • Write unit tests and implement monitoring and incident response;

• Integrate our existing systems with exciting new blockchains • Design and implement low-latency, high-availability, super secure applications and data protection systems • Write highly scalable, high volume services • Write reusable, testable, and efficient code • Design and optimize database schemas • Own, develop and maintain existing crypto services

• Own the architecture for the TC.NET product domain, including integrations, network interactions, and cross‑system communication patterns. • Evaluate current state tech stack and lead its modernization using forward‑looking, practical, incremental approaches (no “throw it all out” solutions). • Define and communicate architectural guardrails, design patterns, and technical direction. • Engage directly with code, prototypes, and deep-dive investigations to resolve complex technical problems. • Coach engineers by zooming into component‑level details when needed, while maintaining domain-level architectural ownership. • Demonstrate the technical rigor expected at this level—this role is not management‑focused; engineering leadership already exists on the team. • Work closely with product partners to ensure architectural designs align with strategic needs. • Communicate effectively with engineering teams, leadership, and stakeholders—must be articulate, clear, and able to simplify complex concepts. • Balance modernization of legacy systems with the evolution toward scalable, cloud native and event driven architectures. • Incorporate AI/ML awareness and AI‑assisted system evolution where applicable; candidates must demonstrate foundational understanding of current AI technologies. • Assess the feasibility of modernization options and create incremental upgrade paths.
