Full-stack Engineer

• Define and evolve the architecture of highly complex solutions, ensuring scalability, resilience, security, and maintainability.
• Establish and communicate the long-term architectural vision aligned with business strategy and the platform’s capabilities.
• Define architectural patterns, frameworks, and software engineering best practices adopted across the organization.
• Lead Proofs of Concept (PoC) and evaluations of new technologies, providing recommendations based on trade-offs.
• Produce Architectural Decision Records (ADRs) and document significant technical decisions for traceability and governance.
• Define the architecture of modern web applications, setting standards for componentization, state management, performance, and accessibility (React, Angular, or Vue.js).
• Architect cross-platform and native mobile solutions, defining navigation patterns, state management, API communication, and offline experience (React Native, Flutter, or Swift/Kotlin).
• Ensure consistency of design systems and user experience (UX) between web and mobile platforms, collaborating with product and design teams.
• Define performance and optimization strategies for web and mobile applications.
• Establish frontend- and mobile-specific security standards: secure storage, API communication, authentication (OAuth2/OIDC), and protection against OWASP Mobile Top 10 threats.
• Guide the team in defining testing strategies for frontend and mobile layers: unit, integration, and end-to-end (Cypress, Detox, Appium) and accessibility testing.
• Technically lead multidisciplinary squads, mentoring mid-level architects and senior developers across backend, web, and mobile layers.
• Conduct code reviews and architectural reviews with focus on quality, security, performance, and adherence to defined standards.
• Act as a mentor to professionals in the area, fostering the team’s technical growth and a culture of engineering excellence.
• Serve as an escalation point for critical technical decisions, resolution of complex problems, and production incident situations.
• Define and evolve the strategy of the internal development platform (IDP), ensuring that tools, standards, and workflows serve the entire engineering organization.

Software Architect III

• Define and structure legacy components, microservices and APIs, ensuring cohesion, low coupling and sustainable evolution of systems.
• Establish development standards, design patterns (SOLID, Clean Architecture, DDD) and practices to continuously reduce technical debt.
• Translate business requirements into scalable, secure and cost-effective technical solutions.
• Conduct technical and architectural reviews, identifying risks and opportunities for improvement.
• Implement and evolve internal developer portals (IDP) such as Backstage (Spotify/CNCF), centralizing the service catalog, technical documentation (TechDocs) and scaffolding templates.
• Define and maintain the IDP Software Catalog, ensuring visibility and governance over all services, APIs and platform components.
• Create and maintain Software Templates (golden paths) to standardize the creation of new services, environments and pipelines with best practices embedded.
• Develop and integrate custom plugins for Backstage to connect internal tools (CI/CD, observability, cloud, ticketing, security).
• Promote a self-service culture, reducing squads' cognitive load and accelerating onboarding of new developers.
• Evaluate and recommend complementary or alternative IDP solutions (Port, Cortex, Roadie, OpsLevel) according to platform maturity.
• Design, implement and maintain continuous integration and delivery pipelines (CI/CD) with a focus on quality, traceability and speed.
• Integrate automated tests (unit, integration and security) into CI/CD pipelines.
• Design and govern advanced deployment strategies: Blue/Green, Canary and Feature Flags.
• Integrate security tools (SAST/DAST) continuously into the development lifecycle, ensuring security without operational friction.
• Ensure adherence to security best practices: authentication, authorization and OWASP Top 10.
• Implement and automate observability strategies: logs, metrics and distributed tracing (New Relic, ELK stack, Prometheus, Grafana).
• Support the definition of IaC strategies and infrastructure automation.
• Mentor and guide developers on architectural and software engineering best practices.
• Act as the technical reference within the squad, collaborating with product, business and infrastructure teams.
• Actively participate in agile ceremonies, contributing technical and architectural perspectives.
