Descrição

• Own features and systems across the full stack, frontend, backend, and infrastructure, from problem definition through production. • Partner with product to break down ambiguous scope and ship in iterative, high-impact releases. • Make real architectural and design decisions in your area, and explain the reasoning so the team can build on it. • Take cutting-edge language models into enterprise customer workflows, where reliability and safety actually matter. • Solve hard engineering problems: API performance, microservices, scaling across channels and brands. • Maintain and improve our AWS infrastructure with a DevOps mindset. • Raise the bar around you. Share what you know, review thoughtfully, and help teammates level up.

🎯 Requisitos

• 5+ years of software engineering, with real ownership of systems you have shipped and run in production. • Strong full-stack engineer in our core stack: Node.js, React, TypeScript, Express. • Solid with AWS (Fargate, Lambda, EC2, SQS) and with PostgreSQL and Redis. • Comfortable with CI/CD pipelines (CodePipeline, GitHub Actions, or similar). • Experienced with microservices and scalable systems. • Product-focused. You think past the code to customer outcomes and business impact. • You have shipped LLM-powered features to production. This is a must, not a bonus. You know what breaks when models meet real users. • High-ownership and direct. You take initiative, fix problems without waiting to be told, and say openly when something is not working.

🏖️ Benefícios

• Real ownership. You will own problems, not tasks, with the autonomy to solve them your way and the trust to do it without a manager in your inbox. • Work that ships and matters. What you build reaches real consumer brands fast. • A category we are creating. The Agent of Record is new ground, with unsolved problems and cutting-edge models, not a crowded field to compete in. • A team that respects your judgment. Globally distributed, async-first, low bureaucracy. We hire adults and treat you like one. • Great salary plus equity or stock grants. Own a piece of what you build. • Learning budget. If you are growing, so are we. • AI-fluency by default. Few places will push your work with production AI further or faster.
