Senior OutSystems Developer

Role Description You will join an existing team and take ownership of features and integrations across a portfolio of live, mission-critical OutSystems products and SaaS, while dedicating most of your focus to building new capabilities that did not exist before. Solution design and delivery — you take responsibility for the architecture of your own work, execute it, and support it in production, within the guidelines the Tech Lead sets for the team. Features and integrations that ship to production — real users, real consequences, and your name on them; from build through unit and integration testing to the bug fixing that makes them solid. Integrations with external systems — connecting OutSystems applications to the wider ecosystem according to the defined architecture guidelines, with attention to correctness and error handling under real conditions. Your share of the existing portfolio — understanding the applications the team maintains well enough to extend them without accumulating hidden debt, and knowing when something needs escalating. Quality before it merges — you develop and apply the instinct to distinguish code that is correct from code that merely looks plausible, before anything reaches production. Shared context that makes the team faster — documenting decisions and patterns, and helping the more junior developers grow through review and example. Qualifications At least 4 years of software development experience, with a minimum of 2 years building on OutSystems (required) Hands-on OutSystems experience, ODC and/or O11. Deep platform expertise is welcome — but so is a strong engineer from an adjacent stack who ramps fast. (required) Strong backend and integration fundamentals: REST APIs, JSON, authentication patterns, and error handling under real conditions (required) Solid grasp of solution architecture and application performance, with the ability to estimate and prioritise your own delivery (required) Experience with unit and integration testing and the bug fixing that follows (required) Active use of AI-augmented development — Claude Code, Cursor, Copilot, Mentor, or similar — as a core part of how you build, not an occasional shortcut (required) Fluency in English, written and spoken (required) Degree in Computer Science or Engineering Requirements Experience integrating LLMs via API into enterprise applications Experience programming with databases — SQL Server, Oracle, or MySQL — and knowledge of database modeling Integration knowledge using AWS or Azure-based services OutSystems certifications Prior experience in small, high-autonomy teams where every person's output is visible and tested daily Benefits Real growth opportunities through structured programs designed to scale your expertise. A global collective of world-class talent, collaborating with enterprise software legends and sought-after thought leaders. An inclusive culture where talented individuals from all backgrounds are empowered to learn, experiment, and make an impact.
