Design and implement integrations with enterprise systems through REST APIs and other interfaces, covering authentication, data mapping, error handling and operational logging.

Build proofs of concept to validate technical feasibility, integration approaches and platform capabilities.

Investigate issues across OutSystems applications, databases, integrations and hosting infrastructure using logs, configuration and reproducible tests; establish root causes and coordinate fixes.

Support on-premises platform configuration, deployment planning and production releases, working with infrastructure and DevOps teams to maintain service reliability.

Write maintainable, tested solutions, review code, and support integration testing, UAT, performance testing and remediation of security findings.

Provide practical technical advice to customers, explain solution options and trade-offs, and constructively challenge proposals when improvements are needed.

Produce clear architecture diagrams, API specifications and technical findings; provide technical guidance and share knowledge with developers and project stakeholders.

The ideal candidate has

An OutSystems 11 developer certification: Associate Developer (O11), an earlier Associate Reactive Developer (OutSystems 11) certification, or a higher-level O11 developer certification.

Practical experience developing, deploying and supporting applications in OutSystems 11 on-premises environments.

Experience with Service Studio, Service Center and LifeTime for development, troubleshooting and deployment.

Experience designing and consuming REST APIs, with a working understanding of OAuth 2.0, OpenID Connect, JWT and API gateway integration.

Working knowledge of cloud hosting and network connectivity, preferably AWS, together with familiarity with Windows Server, IIS, DNS, proxies, firewalls and load balancers.

Strong analytical and troubleshooting skills, with the ability to distinguish symptoms from root causes and support recommendations with evidence.

Strong consulting and communication skills, including active listening, stakeholder engagement and the ability to explain technical concepts to different audiences.

A proactive, adaptable approach, with the ability to work independently, learn unfamiliar systems and balance business priorities with technical constraints.
