Software Engineer (IOS) Technology & Data · Poland remote ·

We're growing our team in Poland and want to be upfront about how this role is structured. As we don't yet have a legal entity in Poland, we work with an Employer of Record (EOR) or umbrella company to onboard talent in the region. This means the role is offered on a fixed term basis via an international contractor agreement — and is fully remote.

Purpose of the job: Senior IOS Developer at Collinson's Travel Experience Division will be at the forefront of bringing our visionary roadmap to life, focusing on delivering globally appealing, customer centric solutions. Acknowledging the importance of regional nuances, the chosen candidate will guarantee that our digital offerings strike a chord at both the universal and localized levels. This role is pivotal in architecting and developing iOS applications that offer a smooth, user-friendly travel experience for our global clientele.

Key Responsibilities:

• Design and build advanced applications for the iOS platform.
• Collaborate with cross-functional teams to define, design, and ship new features.
• Maintain and improve existing codebase, focusing on continuous integration and deployment strategies.
• Work on bug fixing and improving application performance.
• Ensure the best possible performance, quality, and responsiveness of the application.
• Integrate with third-party libraries and APIs, ensuring seamless functionality.
• Continuously discover, evaluate, and implement new technologies to maximize development efficiency.
• Coordinate with the design team to ensure UI/UX best practices are followed.
• Address any security vulnerabilities and work to ensure a secure app environment.
• Stay updated with the latest mobile trends, architectures, and emerging technologies.

Knowledge, skills and experience required:

• 4-8 years of strong design/development experience overall, with 4+ years of mobile development experience.
• You have hands‑on experience building mobile applications using Swift, and solid understanding of iOS app design principles, patterns, and best practices.
• You care about user interaction, usability, and of course, making the interface beautiful.
• Good knowledge of architectural design patterns such as MVVM and MVP, and proven experience ensuring modularized and scalable app architecture.
• Proven experience integrating AI‑assisted development tools and techniques into everyday workflows (e.g. code generation, testing, debugging, performance analysis, or automation).
• You have experience with Cocoapods dependency management in iOS apps.
• You strive for clean code and know how to write flexible tests that won’t break and have experience with different test strategies, such as unit, snapshot etc.
• Good knowledge of design patterns mostly used in mobile development (dependency injection, observers etc).
• You love coding and take the time to reflect on all aspects of your implementation, be it the frameworks, languages or processes.
• Ability to take ownership and drive the development of exciting and impactful new features and products.
• A genuine passion for writing well‑structured, readable, and maintainable code.
• You thrive in a team where you can learn and try new tech, collaborate on technical challenges and grow as a team.

Interview Process:

• Stage 1 - We'll do a short call with one of our Engineering Managers for around 30 minutes, who will tell you more about the team, our products, technology and ask questions about your career history and suitability for the role.
• Stage 2 - You will do a technical test (at home) and we'll review your solution and approach to it.
