• Liderar tecnicamente as squads, promovendo boas práticas de engenharia de software e cultura DevOps. • Acompanhar e orientar o time de desenvolvimento no uso de padrões arquiteturais, testes, versionamento e revisão de código. • Ser referência técnica para resolução de problemas complexos e para validação de decisões técnicas e tecnológicas. • Apoiar a escrita e validação de estórias em BDD, contribuindo para um desenvolvimento orientado ao comportamento e mais próximo das necessidades reais. • Participar ativamente das dinâmicas de inception e discovery, garantindo que os requisitos técnicos estejam claros e bem definidos desde o início. • Promover a integração entre desenvolvimento, DevOps, QA e arquitetura, assegurando entregas contínuas e de qualidade. • Garantir que as soluções estejam alinhadas com práticas modernas de segurança, escalabilidade e performance. • Facilitar a comunicação entre áreas técnicas e não técnicas, traduzindo necessidades de negócio em soluções viáveis e eficientes.

• You will build a best-in-class web experience for sophisticated retail traders on a new, AI-native active trading platform • You will ship core active trading workflows: order entry, positions/holdings, blotter/activity, watchlists, alerts, and high-information-density views • You will build AI-native UI patterns that earn trust: streaming answers, grounded citations/context, uncertainty signaling, pre-trade confirmations, and safe “undo/rollback” experiences where applicable • You will work closely with users and stakeholders to define features, iterate quickly, and drive projects to completion • You will collaborate deeply with backend engineers to design clean contracts for low-latency trading interactions and AI tool integration • You will develop a deep understanding of the markets/trading domain and how to translate it into intuitive, powerful UX

• You will develop a high-performance backend in Rust that supports streaming responses, low-latency tool execution, caching, and reliable orchestration of model + tools • You will build the core AI platform that powers a copilot inside a new, AI-native trading experience • You will design robust APIs and runtime components for AI capabilities: authentication/authorization, rate limits, auditing, tracing, retries, and fallbacks • You will build safe action infrastructure for trading workflows: deterministic order previews, confirmation flows, idempotent tool calls, and comprehensive audit logs • You will partner with product and frontend to enable great AI-native UX patterns (streaming, citations/grounding, "why" explanations, reversible actions) • You will develop a deep understanding of the business domain and help translate it into secure, resilient platform primitives

• Work closely with research engineers to develop productionized ML workflows • Develop and iterate on platform infrastructure for training, validating, and deploying neural networks • Deploy cloud infrastructure and build distributed data-processing pipelines • Develop on an in-house multi-tenant data lake ecosystem supporting the entire lifecycle of machine learning operations • Build internal APIs to serve data, trigger workflows, enforce business logic, etc. • Build CI/CD process and other internal tools to enhance developer productivity
