Senior SiteCore Developer

About the role

Arcsen, a global technology consulting firm serving clients across EMEA, is looking for Senior SiteCore Developers to build the headless Sitecore solution powering a large multi-market website, a member portal and the content layer behind native mobile apps. You will build components, templates and integration handlers that connect Sitecore to the enterprise CRM, and set the patterns the wider build team follows.

Key responsibilities

• Develop Sitecore XM Cloud components, renderings, templates and serialized items, including up to about 200 page templates and variants.
• Build and consume Experience / Edge APIs that expose personalisation tokens (tier, segment, next-best-offer, active campaign) to the front end and to mobile.
• Implement inbound and outbound integration handlers: lead and subscription capture, behavioural events to the customer data platform, self-service case submission and member-action events.
• Implement Sitecore-native search and personalisation surfaces (homepage hero, offers, content blocks).
• Build a source-controlled solution with Sitecore CLI serialization and contribute to the CI/CD pipeline.
• Write fully commented, documented code, take part in code review and uphold security and performance standards.
• Support content migration and integration testing through go-live and hypercare.

Required profile

• Bachelor's degree in Computer Science, Information Technology or a related field.
• 3 to 5 years of professional Sitecore development.
• Hands-on experience with Sitecore XM Cloud or Sitecore Headless (JSS) in production, not proof-of-concept.

Required skills

• Strong C# / .NET and REST API integration skills.
• Sitecore serialization (Sitecore CLI / Sitecore Content Serialization) and CI/CD pipelines.
• Solid understanding of Sitecore content modelling, templates, renderings and workflows.
• Nice to have: GraphQL / Sitecore Edge, Next.js / React and TypeScript, MuleSoft or event-driven integration, multi-language and Arabic (right-to-left) experience, content migration tools, Sitecore certification (10.x or XM Cloud).

What we offer

• Hands-on experience with real-world projects and clients.
• A collaborative and supportive work environment.
• Career growth opportunities.
