The posting

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Tech Lead FullStack based in Brazil.

This role offers the opportunity to lead the development and evolution of critical authentication, authorization, and observability capabilities within a modern multi-tenant platform. You will work across frontend and backend technologies while helping shape secure and scalable identity solutions. The position combines hands-on engineering with technical discovery, architecture, and integration work. You will contribute to OAuth2/OIDC-based authentication, enterprise federation, role management, and identity provider integrations. The role also involves supporting legacy services during a gradual modernization journey, ensuring continuity for existing customers. You will collaborate closely with infrastructure and product teams in a remote-first environment where AI-assisted development and engineering excellence are encouraged.

Accountabilities

  • Develop and evolve the Authentication & Authorization module using OAuth2, including centralized login, product-level role definitions, and enterprise OIDC federation within a multi-tenant architecture.
  • Maintain and support existing authentication flows and services, ensuring compatibility for customers who have not yet migrated to the new architecture.
  • Maintain user and role management services while ensuring stability during the transition to the new platform model.
  • Integrate users and roles from the selected identity provider, such as Keycloak or Auth0, into new services and support identity-data synchronization and migration between legacy and modern models.
  • Implement observability across the modules, including metrics, logging, dashboards, and monitoring capabilities.
  • Evaluate and prototype integrations with identity providers such as Auth0, Keycloak, Okta, Entra ID, and Azure B2C to support the selection of a centralized identity platform.
  • Integrate delivered modules with the central portal and identity platform in collaboration with infrastructure teams.
  • Participate in technical discovery, refinement, and planning for upcoming platform capabilities and improvements.
  • Document architectural and technical decisions while ensuring services remain aligned with a shared-ownership model across cloud infrastructure and individual products.
  • Demonstrated experience in full-stack development, with strong frontend skills in React, TypeScript, and Next.js and backend experience with Node.js, Java, or Kotlin.
  • Practical knowledge of authentication and authorization concepts, including OAuth2, OIDC, and RBAC.
  • Hands-on experience with identity providers such as Auth0, Keycloak, Okta, Entra ID, or Azure B2C.
  • Experience working with messaging and event-driven systems, particularly Kafka or an equivalent technology.
  • Comfortable working within codebases where legacy and modern versions coexist, supporting gradual migrations without disrupting existing customers.
  • Familiarity with observability technologies such as SigNoz, Prometheus, and Grafana.
  • Experience with at least one public cloud provider, such as AWS or Azure, as well as practical Docker experience.
  • Proficiency with Git and CI/CD pipelines, particularly GitHub Actions.
  • Comfortable using AI-powered development tools, such as Claude Code, custom skills, and agents, to support technical refinement, documentation, feature development, and coding.
  • Strong problem-solving, technical communication, collaboration, and documentation skills, with the ability to contribute to technical discovery and make informed engineering decisions.
  • Knowledge of Segregation of Duties (SoD) and/or OpenFGA for fine-grained authorization is considered an advantage.
  • Experience with Kubernetes, GitOps concepts, Anticorruption Layer patterns, and Factory/Strategy patterns for interchangeable identity providers is a plus.
  • If you reside in the Campinas Metropolitan Region, availability to work from the local offices is required in accordance with the applicable attendance policy.
  • Health and dental insurance.
  • Meal and food allowances.
  • Childcare assistance.
  • Extended parental leave.
  • Access to fitness, wellness, and healthcare professionals through Wellhub and TotalPass partnerships.
  • Profit Sharing and Results (PLR).
  • Life insurance.
  • Continuous learning opportunities through an internal learning platform.
  • Access to online courses and language-learning platforms.
  • Discounts through partner programs.
  • Online resources dedicated to physical health, mental health, and overall well-being.
  • Pregnancy and responsible-parenthood support and courses.
  • Opportunities to work with modern technologies, AI-assisted development, cloud platforms, identity management, and large-scale platform modernization.
  • Remote work environment, subject to the applicable office attendance requirements for employees in the Campinas Metropolitan Region.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
