About The Role

What You'll Do
• Learn and contribute to our Salesforce platform: data model, automation logic, and backend features with Apex
• Participate in the design and implementation of integrations between Salesforce and internal/external services
• Contribute to backend services (TypeScript/Node.js) with guidance from your squad
• Work with Product and Design to understand user needs and translate them into working software
• Write clean, tested code and take part in code reviews
• Explore AI-assisted development tools (Cursor, Claude Code, GitHub Copilot) to accelerate your learning and output Profil Required 🔎 What We're Looking For
