Full-time
Appnovation Technologies
About us
Appnovation is a global, full-service digital partner that combines Strategy, Experience & Design, Engineering and Managed Services. We build digital solutions that deliver real impact today and serve as foundations for future growth. Bold ambition. Practical action. Endless possibilities.
About the Role
As a Senior OutSystems Developer, you will bridge the gap between complex business requirements and technical execution by rapidly transforming concepts into production-ready enterprise applications using OutSystems 11 (O11) and OutSystems Developer Cloud (ODC). You will play a key role throughout the development lifecycle, taking ideas from prototype to production with a strong focus on secure backend architecture, relational database integration, and seamless frontend execution. Leveraging the OutSystems platform, you will accelerate delivery workflows while ensuring every application meets rigorous enterprise standards for performance, security, and scalability. You will collaborate closely with UX Designers, Innovation Leads, and fellow developers, translating Figma design systems and connecting external SQL databases to deliver cohesive, high-quality solutions. This role is ideal for a pragmatic systems-thinker who thrives in a fast-paced environment, excels at procedural logic, and has a passion for building robust enterprise architecture within low-code platforms.
Key Responsibilities
- Build secure, scalable enterprise applications from prototype to production within OutSystems 11 (O11) and OutSystems Developer Cloud (ODC), emphasizing robust backend architecture, relational database design, and complex logic structures.
- Develop and translate UI prototypes into production-ready frontends based on client needs.
- Align all components with existing design systems, including tokens, color, typography, and brand guidelines
- Design and implement RESTful APIs and backend services, integrating external SQL databases (specifically PostgreSQL) via ODC Connections and O11 Integration Studio for efficient data management.
- Manage complex application state and multi-step business logic securely on the server side.
- Implement Role-Based Access Control (RBAC), server-side validation, and performance optimizations across the OutSystems stack.
- Collaborate with UX Designers, Innovation Leads, and other developers throughout the development lifecycle, participating in code reviews and sharing platform best practices.
- Assist with application lifecycles and release management, helping to handle deployments and code merges using LifeTime and the ODC Portal.
- Document technical decisions and implementations in Jira.
Qualification
- 5+ years of hands-on experience developing enterprise-grade applications specifically within the OutSystems platform.
- Experience working in ODC, alongside strong O11 foundational knowledge.
- Understanding of the OutSystems 3-Layer Canvas (O11) and App/Library containerization (ODC) to build modular, maintainable applications.
- Solid experience integrating and querying external relational databases (e.g., PostgreSQL) using ODC Connections and O11 Integration Studio, paired with strong raw SQL skills.
- Proficiency in consuming and exposing RESTful APIs within a low-code environment.
- Ability to design and manage application state without relying on modern JavaScript frontend frameworks.
- Familiarity with OutSystems release management tools and deployment processes, including LifeTime and the ODC Portal.
- Solid understanding of enterprise web security principles, including server-side validation and preventing vulnerabilities like Insecure Direct Object Reference (IDOR).
- Previous experience working in the Insurance or Financial Services sector is a bonus.
- Active OutSystems Certifications (e.g., Associate/Professional Reactive Developer, ODC Ready) are a plus.

- Challenging and rewarding work with real impact
- Growth opportunities for personal and professional development
- Exposure to exciting projects and high-profile clients
