About the role:

We are currently seeking a Senior iOS Developer for our client, a leader in the financial services industry. If you are passionate about high-quality software and motivated to make a significant impact on our mobile development within one our client’s flagship trading platforms, we are interested in creative, innovative, and problem-solving candidates who deliver robust software designs that are fully tailored to our users. To be a successful member of this team, you must prioritize quality and be self-motivated to achieve your goals.

Get ready to work on a challenging project in the innovative world of financial services. By working for a leading global company, you will be part of a team playing a vital role in building and maintaining a cutting-edge technology platform.

This is a contract position with Randstad Canada, working on behalf of our global financial services client.

Main Responsibilities:

• Contribute to the mobile application strategy

• Design and implement features for a suite of Mobile Applications

• Learn and apply new technologies, best design practices and usability patterns

• Contribute to end-to-end system architecture, working with back-end engineers

• Collaborate with product managers and other technical teams to create optimized and delightful user experiences.

• Maintain source code quality, provide code review feedback, and help create team coding principles.

• Mentor, train, and provide guidance to other team members and lead by example.



Main Qualifications:

• Bachelor's degree in Computer Science (or equivalent experience)

• 7 years of software development experience with Apple platforms

• Strong knowledge of iOS UI design principles, patterns, and best practices. iPadOS is a plus. The ability to cleanly integrate with both in one codebase is ideal.

• Strong fundamentals with XCTest, and hopefully you’ve heard of SwiftTest. You don’t aim for 100% coverage, but instead focus on what really matters.

• Excellent debugging and optimization skills, including use of Instruments for identifying issues as they arise, and utilizing performance testing to ensure they don’t happen in the first place.

Benefits:
