At CI&T, we help large enterprises transform the potential of AI into real business impact with AI Deployment, AI-native execution, and tech-integrated business solutions.
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.
We are looking for a Senior or Master Full Stack Developer who can take product requirements, design the technical solution, and build it.
You will own features end to end on a cloud enterprise platform: backend services, APIs, integrations, and React interfaces that support complex business workflows. You will also support the live project — investigating issues, fixing bugs, and keeping the platform running.
This role uses AI intensively in day-to-day work, with judgment: you decide when it helps, review the output, and remain accountable for the result.
What you will do:
- Work with product to understand requirements, then design and implement the solution;
- Build backend services in Python and frontend applications in React;
- Design and maintain REST APIs, data contracts, and integrations with external systems;
- Build resilient systems (async processing, retries, fault tolerance);
- Contribute to the design system, reusable components, and Storybook;
- Use PostgreSQL, Temporal, Docker, and AWS Bedrock;
- Write tests, follow accessibility standards, and keep the UI maintainable;
- Investigate and fix bugs in production and in development;
- Add observability with OpenTelemetry and Grafana;
- Work with Terraform and GitHub Actions for CI/CD;
- Contribute to architecture decisions and help raise engineering standards;
- Use AI tools heavily to speed up design, coding, and troubleshooting — always with review and sound engineering judgment.
Required Qualifications:
- Advanced English;
- Hands-on production experience with both backend and frontend technologies;
- Python (production), REST APIs, Docker, API Gateway, PostgreSQL;
- Event-driven / async processing, message queues, workflow orchestration (e.g. Temporal);
- GitHub Actions, observability (OpenTelemetry, Grafana, or similar);
- React, JavaScript or TypeScript, HTML/CSS, responsive UI, REST integration;
- Storybook, frontend testing with Playwright, Git;
- Knowledge of Terraform and design systems;
- Ability to turn product requirements into a technical design and working software;
- Distributed systems, resilience patterns, auth (OAuth, OIDC, SSO, RBAC);
- Production troubleshooting and bug fixing, accessibility, clear communication;
- Comfortable using AI as a core part of the workflow, with the judgment to validate, correct, and own the output.
Nice to Have:
- AI/LLM integrations, enterprise SaaS, Jest/Cypress, design systems at scale, cloud frontend deploys, mentoring.
