– Contribute to high-quality engineering practices through thoughtful technical
decisions, clear pull requests, and constructive code reviews.
– Refactor and modernize legacy code and support the transition toward a modular
application architecture.
– 5+ years of iOS development experience, ideally in product-driven or high-scale
environments.
– Strong problem-solving skills and the ability to turn complex challenges into actionable
steps.
– Focus on scalability, maintainability, and long-term platform health.
– Experience working in Agile teams with planning, estimation, and iterative delivery.
– Highly self-managed, dependable, and able to operate effectively with minimal
supervision.
– Clear communicator who asks clarifying questions, keeps stakeholders informed, and
follows through on commitments.
– Comfortable navigating ambiguity, prioritizing effectively, and proposing practical
solutions in a fast-moving environment.
– Strong expertise in Swift, MVVM, Clean Architecture, and modular app architecture.
– Experienced with Combine, UIKit (mandatory), SwiftUI, Cocoapods, SPM, and
dependency injection.
– Solid experience integrating RESTful APIs, data processing, and error management.
– Able to analyze and improve app performance, memory usage, stability, and
responsiveness.
– Proven ability to deliver polished, intuitive, user-focused mobile interfaces.
– Confident with standard engineering workflows including Git, branching strategies, pull
requests, code reviews, CI/CD, and release processes.
– Experience working in mature Agile product teams, including backlog refinement,
sprint planning, QA collaboration, and iterative delivery.
– Excellent communication skills in English.
– Participation in interesting and demanding projects.
– Flexible working hours.
