• Code review and mentorship of associates, intermediates, and other senior members on the team
• Work with business partners outside of you team to explain and champion high-level technology approaches

Location: 

This is a hybrid role based in our Warsaw office.

Required Qualifications:

• Strong understanding of software architecture, design patterns, and UI best practices

• Proven ability to lead frontend initiatives — from architectural planning to implementation and rollout
• Solid experience working with RESTful and/or GraphQL APIs
• Familiarity with frontend performance optimization and accessibility principles
• Excellent communication skills and a collaborative mindset

Preferred Qualifications: 

• Experience with AngularJS (we have legacy part that will be migrated to React)
• Experience with federated modules
