Senior OutSystems Developer

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. The balance we aim for is roughly seventy percent innovation — new applications, new integrations, new capabilities — and thirty percent maintaining and evolving what is already running.

Responsibilities

Solution design and delivery; Features and integrations that ship to production; Integrations with external systems; Your share of the existing portfolio; Quality before it merges; Shared context that makes the team faster

Requirements

At least 4 years of software development experience, with a minimum of 2 years building on OutSystems; Hands-on OutSystems experience, ODC and/or O11; Strong backend and integration fundamentals: REST APIs, JSON, authentication patterns, and error handling under real conditions; Solid grasp of solution architecture and application performance, with the ability to estimate and prioritise your own delivery; Experience with unit and integration testing and the bug fixing that follows; 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; Fluency in English, written and spoken; Degree in Computer Science or Engineering

Nice to have

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
