• Experience implementing data mapping, transformation, orchestration, and error recovery mechanisms.
• Knowledge of API authentication and security standards, particularly OAuth 2.0 and JWT.
• Strong SQL skills and experience working with relational databases, preferably SQL Server.
• Familiarity with automated testing, API testing, version control, and CI/CD practices.
• Demonstrated ability to troubleshoot complex integration issues involving multiple applications and services.
• Experience supporting production systems, conducting root cause analysis, and implementing long-term fixes.
• Strong analytical thinking, structured problem‑solving abilities, and attention to detail.
• Ability to work independently, manage competing priorities, and take ownership of technical deliverables from conception to completion.
• Excellent communication skills, particularly when explaining technical concepts, issues, and solutions to customers.
• Confidence participating in customer‑facing technical meetings and collaborating with stakeholders from different business and technical backgrounds.
• A collaborative and proactive mindset, with the flexibility to work across engineering, implementation, QA, and business teams.
• Location requirement: Must be physically based in Brazil.

Nice to have:

• Experience with Workato or other enterprise Integration Platform as a Service (iPaaS) solutions.
• Knowledge of Kafka or similar event-streaming and messaging technologies.
• Experience with AWS services, particularly API Gateway, Lambda, and IAM.
• Familiarity with enterprise ERP platforms such as SAP and Oracle.
• Experience with ETL processes, data integration pipelines, and enterprise data management.
• Familiarity with development and collaboration tools such as GitLab, Postman, pytest, and Jira.
• Previous exposure to construction technology, capital project management, or project controls software.
• Experience working with OpenAPI specifications and enterprise API documentation.

Previous experience with Workato is not mandatory. Strong integration engineering fundamentals, C# expertise, and the ability to learn new technologies are the key priorities. Benefits:

• Competitive technical environment: Work on challenging enterprise integration projects involving complex systems and modern technologies.
• Technical ownership: Take responsibility for integration solutions throughout their entire lifecycle, from architecture and development to production deployment.
• Professional autonomy: Enjoy the opportunity to independently solve complex engineering challenges and influence technical decisions.
• Technology exposure: Work with C#, .NET, REST APIs, SOAP, Kafka, Workato, AWS, SQL Server, OAuth 2.0, and modern integration architectures.
• Continuous learning: Expand your expertise across enterprise platforms, cloud technologies, middleware, and event-driven systems.
• Customer interaction: Collaborate directly with customers and gain exposure to different enterprise environments and business processes.
• Career development: Contribute to reusable integration frameworks, architectural improvements, and long‑term platform evolution.
• Meaningful impact: Build reliable solutions that improve data exchange, automate business processes, and enhance customer operations.
• Location: Brazil, with the position based in São Paulo.
• Employment arrangement: Specific contract type, compensation, benefits, and working arrangements were not disclosed in the original job description and will need to be confirmed during the recruitment process.
