LEAD MOBILE DEVELOPER (iOS)

SWIFT 

Department:  Engineering

Reports to:  Technical Lead / Line Manager 

WHO PLATFORM45 IS

We are responsible for code changing the lives of people around the world, every day. We solve complex problems and build big ideas. And we don’t stop. We believe in the ability of technology to make the world a better place; we’re driven to rip through conformity and create new solutions, and smarter habits. We know why we’re here: To unleash the potential of people through the power of technology. We are people multiplied by the power of tech and together we are changing the world.

CONTEXT | THE ROLE

Being a developer is not just about the ‘code’. At Platform45, our developers are all-rounders who can write exceptional, well-designed, and testable code but also collaborate effectively within their team and with others. Over and above the technical know-how, you’ll need strong verbal and written skills as you build up relationships with our clients. At Platform45, we treat our clients like partners — they’re an important part of the team and we strive to work together to build something beautiful.

As the Lead Mobile Developer (iOS), you set the technical direction and quality bar for iOS across the engagement. You own the architecture of the iOS application(s), lead and mentor a team of iOS engineers, and are accountable for the delivery of the iOS workstream. Continuous learning is central to the role — whether that means new language features, keeping ahead of industry trends and methodologies, or evolving the tech stack — so that together we build the best products to solve our client’s needs.

ROLE RESPONSIBILITIES | THE WHAT & THE HOW

The Essentials

Software Development

Lead the design, development, implementation, and maintenance of scalable and robust iOS applications that meet client requirements and industry standards.

Technical Leadership

Set the technical direction and standards for iOS development across the team and engagement, ensuring adherence to best practices, coding standards, and architectural principles. Take full accountability for the iOS workstream, problem-solving and self-correcting where needed, and ensure the scalability, performance, and maintainability of iOS applications through sound design patterns (MVVM, VIPER, etc.).

Team Leadership

Lead, mentor, and grow a team of iOS engineers — setting objectives, supporting professional development, giving regular feedback, and helping to shape the iOS hiring bar through interviewing and technical assessment.

Solution Architecture

Own the architecture of the iOS application(s). Collaborate with stakeholders to define system architecture, identify technical requirements, and design innovative solutions that address complex business challenges.

Delivery Ownership

Own estimation, planning, and delivery of the iOS workstream, ensuring high-quality releases are shipped within scope and timelines, and reporting progress, risks, and dependencies to the Technical Lead and stakeholders.

Collaboration

Collaborate with product managers, UX/UI designers, backend developers, and the Android lead to define and implement new features, enhance existing ones, and ensure a consistent cross-platform experience.

Code Review and Quality Assurance

Establish and enforce code review, testing, and quality assurance processes to ensure the reliability, performance, and security of the iOS application. Champion unit and integration testing, and optimise performance across different devices and iOS versions.

Requirement Analysis

Work closely with clients to understand their needs, gather requirements, and propose technical solutions that align with their objectives and budget constraints.

Continuous Improvement

Stay updated on emerging technologies, industry trends, and best practices in software development, and leverage this knowledge to enhance our development standards, processes, and capabilities.

Mentoring

Provide mentorship to junior / less-experienced developers, assisting them in growing their technical expertise and guiding them on best practices, coding standards, and architectural principles.

TECHNICAL REQUIREMENTS

• Bachelor’s degree in Computer Science, Software Engineering, or a related field, or provable, self-taught development skills with a good understanding of how systems work.

• 7+ years of Native iOS (Swift) development, including demonstrable experience leading or mentoring a team of iOS engineers, with a proven track record of delivering successful apps to the App Store.

• Expertise in Swift and Objective-C, with deep knowledge of the iOS SDK and Apple’s Human Interface Guidelines.

• Proficiency with modern iOS development, including SwiftUI, Combine, and Swift Concurrency (async/await).

• Strong experience with mobile architecture patterns (MVC, MVVM, VIPER) and design principles (SOLID, DRY, etc.).

• Experience with advanced iOS frameworks such as Core Data, Core Animation, and Core Location.

• Expertise in integrating RESTful APIs and managing third-party libraries.

• Proven experience in performance optimisation, memory management, and debugging iOS applications.

• Experience defining and owning version control (Git), CI/CD, and automated testing practices for a mobile team.

• Experience owning delivery of a mobile workstream — estimation, planning, and stakeholder communication.

• Having experience working within a high-growth tech startup would be an advantage.

• Have brilliant problem-solving abilities that take product design, process, and technical aspects into account.

• Have the ability to clearly articulate solutions for a technical and non-technical audience.

CRITICAL COMPETENCIES

• Proven people-leadership skills — able to grow, motivate, and hold a team to a high standard while keeping them engaged.

• You have an entrepreneurial mindset and can understand the business value of a project.

• You have the ability to research and develop new products and modifications to existing software when needed.

• You are someone who is motivated, energetic, and always focused on the task at hand.

• A strategic thinker who can work under pressure, independently problem-solve, and draw knowledge from a broad range of experiences.

• A proactive, continuous, and quick learner who is genuinely excited about industry trends and has a passion for technology and knowledge.

• A resourceful, ‘big-picture’ thinker who considers how the code that is written will have an impact later on.

• Good communication and teamwork are critical — you’ll be dealing not only with developers but also designers, product owners, clients, and other key stakeholders.

• Play a mentorship role to our interns, juniors, and other less-experienced engineers.
