We're looking for a mid-level OutSystems Developer to join a support and evolutive development team, keeping a live platform running smoothly while continuously improving it. This isn't greenfield build work - it's about owning a production application, fixing what breaks fast, and shipping enhancements that make it better over time.
You'll work closely with business and IT teams, balancing incident response with planned development, and making sure both get the attention they deserve.
What you'll do
- Diagnose and resolve incidents and bugs in existing OutSystems applications, keeping downtime and business impact to a minimum
- Design and build new features and enhancements (evolutive development) based on business requirements
- Perform root-cause analysis on recurring issues and propose fixes that prevent them from coming back
- Monitor application performance and health, and act on issues before they become incidents
- Maintain and improve technical documentation, including architecture notes and support runbooks
- Participate in code reviews and apply OutSystems best practices for performance, security, and maintainability
- Manage integrations with external systems (REST/SOAP APIs, databases, third-party services)
- Work within SLA-driven support processes, prioritising tickets by severity and business impact
- Collaborate with product owners and the wider delivery team on sprint planning and backlog refinement
What you bring
- 2-4 years of hands-on OutSystems development experience (Reactive and/or Traditional Web apps)
- Solid understanding of the OutSystems platform: Service Studio, Integration Studio, Lifetime
- Experience supporting live applications: triaging incidents, debugging in production-like environments, and working under SLAs
- Working knowledge of REST/SOAP web services, SQL, and relational databases
- Understanding of OutSystems architecture principles and performance best practices (query optimisation, aggregate usage, screen performance)
- Familiarity with Agile/Scrum ways of working
- Good English communication skills, written and spoken
- A methodical, problem-solving mindset: comfortable moving between "fix it now" and "build it right"
Nice to have
- OutSystems certification (Associate or Professional level)
- Experience with CI/CD pipelines for OutSystems (e.g. OutSystems Pipelines, Azure DevOps)
- Exposure to ITIL-based support processes
- Experience in various industries
What the project looks like
- Mixed workload: reactive support (incidents, bug fixes) plus planned evolutive development (new features, improvements)
- Direct engagement with stakeholders, not just internal teams
- Clear SLAs and ticket prioritisation, so you always know what matters most
- Room to bring your own ideas on how to make the application better, not just keep it alive
