• Develop and maintain components for the Cycloid and n8n platforms (APIs,integrations, automation scripts)
• Build CI/CD pipelines to support automated delivery of platform components
• Develop new solutions to replace or reinforce existing tools in the PAT portfolio
• Collaborate closely with Domain Architects, the Lead Developer, and the Lead Architect to deliver robust, maintainable solutions
• Develop and maintain the CJ API (Go/Python) that serves dynamic form data and handles request lifecycle
• Build and maintain n8n workflows and sub-workflows (transversal building blocks)
• Develop Cycloid Stack Forms (.forms.yml) and associated handlers (Python)
• Implement integrations between platforms (Cycloid ↔ GitLab, n8n ↔ CMS, n8n ↔ ServiceNow, n8n ↔ CMS)
• Write and maintain automated tests for platform components CI/CD & Automation
• Design, build, and maintain CI/CD pipelines (GitLab CI, Concourse)
• Automate build, test, and deployment processes for platform components
• Manage container image builds and promotion across environments (Dev → Acceptance → Production)
• Implement GitOps practices for platform deployments (ArgoCD, Helm)
• Analyse existing tools to identify replacement or improvement opportunities
• Develop new solutions (APIs, scripts, integrations) to replace legacy tools or extend platform capabilities
• Ensure backward compatibility during migration from legacy to new solutions
• Document all developed solutions (architecture, usage, operational procedures)
• Participate in code reviews and enforce coding standards
• Write clear technical documentation for developed components
• Support Domain Architects in developing their Cycloid stacks and n8n workflows
• Contribute to the definition of development best practices and reusable patterns
