Responsibilities:
- Architect, design, and implement enterprise-grade OutSystems 11 (O11) applications across multi-environment landscapes (DEV/UAT/PROD), ensuring scalability, maintainability, and performance
- Translate complex functional and non-functional requirements into technical solution designs, architecture decisions, and implementation blueprints.
- Develop and optimize Reactive Web and Mobile applications using OutSystems best practices and performance-oriented design patterns.
- Design and implement integration architectures leveraging REST, SOAP, OData, and event-driven/middleware-based communication patterns.
- Build and maintain custom OutSystems extensions via Integration Studio for advanced system interoperability.
- Implement and enforce application lifecycle management (ALM) using LifeTime, including deployment strategies, versioning control, and environment synchronization.
- Conduct performance tuning and root cause analysis (RCA) for production issues across application, database, and integration layers.
- Design and implement database schemas, SQL queries, and optimization strategies to support high-volume transactional systems.
- Develop reusable framework components, Forge assets, and reusable UI/logic modules to enforce standardization across applications.
- Implement enterprise-grade authentication and authorization mechanisms (SAML, OAuth2.0, OpenID Connect, LDAP/AD integration).
- Ensure applications adhere to secure coding standards aligned with OWASP Top 10, including vulnerability mitigation and security hardening.
- Participate in technical design authority reviews, architecture governance sessions, and peer code reviews.
- Support full testing lifecycle including unit testing, SIT, UAT, regression testing, and production validation.
- Design and support CI/CD pipelines, automated deployment processes, and DevOps workflows.
- Collaborate with infrastructure teams on cloud deployments (AWS/Azure), including environment configuration, monitoring, and operational readiness.
- Maintain detailed technical documentation covering architecture, integrations, configurations, and deployment processes.
