[Hiring] Master Full Stack Developer @CI&T

Role Description

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.

• 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

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)

• 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

Requirements

• AI/LLM integrations
• Enterprise SaaS
• Jest/Cypress
• Design systems at scale
• Cloud frontend deploys
• Mentoring
