Descrição

• Full ownership of features: take responsibility from concept and architecture to production deployment. • Collaborate with the architect and make independent architectural decisions within your domain. • Work autonomously on complex, distributed systems ensuring scalability, reliability, and performance. • Backend development with Ruby on Rails 8: performance tuning, background jobs (Sidekiq), custom gem development, REST and GraphQL APIs, versioning, rate limiting, secure auth patterns. • Implement microservices and event-driven architectures with inter-service communication patterns. • Database design and optimization for PostgreSQL: query optimization, indexing, partitioning; implement caching with Redis or Memcached. • Frontend development: build performant UIs with JavaScript/TypeScript and frameworks (React, Vue, Angular); optimize bundlers (Webpack, Vite, esbuild); use Hotwire and Tailwind CSS. • Design and maintain CI/CD pipelines; containerize via Docker and Kubernetes; ensure observability (monitoring, logging, Grafana). • Integrate LLMs and agent frameworks (LangChain, CrewAI); implement MCP connectors, vector DBs for RAG, and real-time agent interfaces (WebSockets, SSE, streaming APIs). • Product-focused engineering: implement business logic, optimize for conversion and retention, support A/B testing and feature flags. • Apply security best practices (OWASP), OAuth/JWT flows, encryption at rest and in transit. • Follow TDD with high automated test coverage; perform integration and end-to-end testing; lead code reviews and documentation.

🎯 Requisitos

• 8–12 years of experience as a full stack developer in complex, distributed systems. • Advanced Ruby on Rails (v8) expertise, including performance tuning, Sidekiq, and custom gem development. • Strong knowledge of PostgreSQL with query optimization, indexing, and partitioning. • Advanced JavaScript/TypeScript (ES6+) skills with deep experience in frameworks such as React, Vue, or Angular. • Proficiency in REST and GraphQL API design and implementation. • Experience with microservices, event-driven architecture, and inter-service communication. • Strong understanding of caching strategies (Redis, Memcached) and database design for high load systems. • Solid DevOps skills, including CI/CD pipelines, Docker, Kubernetes, monitoring, and observability. • Hands-on experience with TDD and achieving high levels of automated testing. • Proven product-oriented mindset with experience implementing feature flags, analytics, and A/B testing. • Familiarity with LLM integrations, vector databases, RAG patterns, and agent frameworks (LangChain, CrewAI). • Knowledge of MCP (Model Context Protocol) for connectors and agent context management. • Strong background in security best practices, including encryption at rest and in motion. • Ability to work with Linux-based environments and infrastructure automation. • Experience with Slack, Telegram, WhatsApp, Teams integrations and WebSocket-based communications. • Fluent English (B2 or higher) and Spanish, with excellent communication skills. • Preferred: Experience with Python (AI/ML), Node.js, and interest in emerging languages like Mojo, Crystal, or Hexcute. • Preferred: Deep understanding of DDD and advanced design patterns (SOLID). • Preferred: Prior experience in startups or scale-ups, balancing speed and quality while scaling technical platforms.
