***About Us*** Magalu is one of Brazil's largest retail companies, recognized for its innovation and digital presence. Magalu's technology team comprises innovative professionals passionate about transforming digital retail. Focused on agile and scalable solutions, they develop projects that impact millions of customers. In a collaborative environment, they continuously pursue excellence in technology and innovation. **Job Description** We are the architects of the technological intelligence driving our nationwide logistics operations, orchestrating connections among stores, distribution centers, and delivery personnel to deliver products across the entire country. Our mission spans from developing intuitive applications empowering drivers and robust systems ensuring the efficiency of *fulfillment* warehouses, to route optimization engines and agile digital solutions built to solve day-to-day operational challenges. **What You’ll Do** As the team’s technical anchor, you will assume end-to-end responsibility: * **Specification:** Translate business problems and complex inventory concurrency/synchronization rules into clear, complete, and executable specifications. * **Architecture & Orchestration:** Design scalable technical solutions and create/evolve specialized agents for architecture, implementation, testing, and quality. * **Agent Governance:** Define technical and functional *guardrails* to ensure security and systemic consistency of deliveries made by the agent ecosystem. * **Validation:** Build rigorous validation *harnesses* to test behaviors, inventory movement rules, and quality criteria. * **Continuous Quality:** Apply TDD practices, orchestrate AI-assisted development workflows, and continuously evaluate delivery quality. * **Troubleshooting:** Investigate critical production incidents by analyzing complex flows and writing optimized queries to identify root causes in synchronization bottlenecks. **What We Expect From You (Requirements)** **Our Tech Stack & Software Development** * **Solid Full-Stack Experience:** Autonomy to work with **ReactJs** (Front-end), and proficiency in **PHP (Laravel and Hyperf), Node.js, and NextJS** (Back-end). * **Architecture & Data:** Expertise in distributed architectures, microservices, APIs, and high-volume messaging. Modeling in relational databases (**MySQL**) and NoSQL (**Mongo**). * **Infrastructure:** Solid hands-on experience with Cloud platforms (**AWS and Google Cloud**) and CI/CD pipelines (**GitLab, Argo CD**). **Engineering Thinking & Behavior** * **Ownership & Long-Term Focus:** An engaged profile that embraces problems (even those not seemingly “yours”) and focuses on building durable products. * **Availability & Collaboration:** Being accessible, having ease in mentoring and supporting less experienced developers and the Product team. * Strong ability to decompose complex problems, abstract, and reason systemically. **Quality & Reliability** * Deep-rooted culture of TDD, automated testing (integration, regression, *contract testing*), and creation of validation *harnesses*. Best practices in observability. **AI Applied to Engineering** * Active experience and orchestration of tools such as **GitHub Copilot** or similar. * Solid understanding of *Prompt Engineering*, *Context Engineering*, and *Agentic Workflows*. **Nice-to-Haves (What Will Make You Shine)** * **Exceptional PHP Proficiency:** As PHP is foundational in our current ecosystem, mastery of high-performance PHP (Hyperf/Laravel) is a significant advantage. * Experience with **Specification-Driven Development (SDD)**, agent construction, and use of **MCPs (Model Context Protocol)**. * Prior technical background in logistics systems, WMS (Warehouse Management System), rigorous inventory control, or large-scale e-commerce. * Platform engineering and evaluation of LLMs in multi-agent systems. **How We Measure Your Success** Your performance will be assessed less by the volume of code produced and more by your ability to: * Create *specs* of the highest quality. * Build robust *guardrails* and reliable *harnesses*. * Increase the autonomy of AI agents within our pipeline. * Reduce rework and improve delivery speed/quality. * Scale Magalog’s engineering through intelligent automation. **The Mindset We Seek** **We’re not looking for people just to write more code.** We seek developers capable of designing systems, specifications, and validation mechanisms that enable AI agents to produce software with quality, security, and scale. This role represents the evolution of the traditional developer into an *AI-Native Engineer*, acting as architect, orchestrator, and guardian of the integrity of our systems via an agentic development ecosystem. **Work Model** We adopt a 100% remote model, providing flexibility while maintaining virtual interaction with the team to ensure effective collaboration and a continuous growth environment. ‘’If you seek a growth-oriented and challenging environment, come be happy!’’ Our values unite us, and our differences empower us as a group. More than equality, we seek equity: Here, there is space to be authentic, regardless of gender, ethnicity, race, sexual orientation, creed, or disability.
