With 30 years of experience in technological transformation, we accelerate innovation with expertise in agentic SDLC, application modernization, Data & AI, martech, and business strategy.
We are 8,000 CI&Ters across more than 25 countries, collaborating to build solutions with real impact. AI is already part of how we work, evolve, and innovate every day.
**Important**: If you reside in the Campinas Metropolitan Region, your presence at our city offices is mandatory, per our current attendance policy.
The Challenge
You will join an established, production-ready connected vehicle ecosystem featuring a native mobile app (iOS/Android), a Java/Spring Boot backend, and cloud infrastructure on AWS/Kubernetes. The product has real users,
integrates with external partners and legacy systems, and maintains an active roadmap of new features. This environment offers the best of both worlds for mid-level professionals: real technical challenges supported by the structure of a senior team to foster growth.
You will work side-by-side with the Tech Lead and Senior Developer, responsible for incremental features, bug fixes, preventive maintenance, and expanding test coverage. The current context is one of transition toward technical maturity — meaning engineering best practices are not suggestions, but expectations. There is room to learn, but also real responsibility from the first sprint.
What You’ll Do
* Implement medium-complexity features in REST/GraphQL APIs using Java/Spring Boot, following team technical standards
* Develop and maintain functionality in native mobile apps (Android/Kotlin)
* Fix production and staging bugs with documented diagnostics and root-cause-oriented solutions
* Write unit and integration tests as part of the development workflow
* Perform preventive maintenance on existing modules, identifying areas for improvement
* Participate in technical refinement rituals, contributing questions, suggestions, and estimates
* Support the senior team in integrations with external partners
What We Need
* Experience in native mobile development: iOS
* Familiarity with cloud environments — AWS preferred — and basic container concepts
* Experience with Git and collaborative workflows (pull requests, code reviews, branches)
* Practice with automated testing: unit tests and, ideally, integration tests
* Ability to work with legacy code: read, understand, and evolve it without breaking existing functionality
What Will Set You Apart
* Experience with Java and Spring Boot in REST API development
* Knowledge of GraphQL (consumption and creation of queries/mutations)
* Prior exposure to projects involving third-party integrations (payments, partner APIs, ERPs)
* Knowledge of observability tools: logs, basic metrics, alerts
* Experience with CI/CD pipelines and build/deploy automation
* Familiarity with Kubernetes or Docker in local development and staging contexts
* Interest in vehicle connectivity, IoT, or mobility products
Soft Skills That Make a Difference
* Genuine desire to learn: proactively and consistently seek knowledge
* Honest communication: ask for help at the right time — a sign of maturity
* Attention to detail: know when the code is good enough to ship
* Active collaboration: team results matter more than individual brilliance
* Ownership of deliverables: test, validate, monitor in production
* Technical curiosity: want to understand how the system works as a whole
