Senior Developer

Senior Developer

Svitla Systems Inc. is looking for a Senior Developer to build enterprise applications on OutSystems, working in joint teams with OutSystems Professional Services.

In this role, you’ll develop features end to end, from data models and business logic to user interfaces and integrations. AI is at the core of this position: you’ll build AI features into applications, use AI coding tools in your daily work, and share practical AI engineering experience with the wider team.

Prior OutSystems experience is not required. You’ll receive structured training and certification on OutSystems 11 (O11) and OutSystems Developer Cloud (ODC) at the start of the engagement, followed by hands-on learning on live projects. You’ll work as one team with OutSystems Professional Services developers and consultants, learning their delivery practices and sharing your AI expertise with them in return.

Engagement: Full-time
