What you need to have:

• 8+ years' experience in a similar software engineering role.
• Strong hands-on experience with Angular.
• Proven expertise in TypeScript and JavaScript.
• Ability to operate independently and take ownership of delivery.
• Strong communication skills and the ability to work effectively with both technical and non-technical colleagues.
