Job description

London | 3 days per week in the office

I'm working with a high-growth consumer beauty and wellness business that's using technology to build a genuinely differentiated e-commerce experience for its growing member base. They're now looking for a Senior iOS Engineer to help shape the next stage of their mobile product.

The app launched around 18 months ago and is now at an exciting point in its development. Rather than joining a large mobile team and owning a small part of the roadmap, you'll be the senior iOS specialist within a lean team, working closely with Engineering, Product and UX to influence both what gets built and how it's built.

The Opportunity

You’ll have genuine ownership over the iOS application, helping evolve it from its existing e-commerce foundations into a broader mobile experience for customers.

You’ll be involved in:

• Building and evolving the iOS application using Swift
• Developing new shopping and customer experiences
• Integrating APIs and services across the wider technology platform
• Working closely with Product, UX and other engineering teams
• Improving app quality through automated testing, observability and performance
• Contributing to the mobile technology roadmap
• Mentoring and sharing best practice across the wider engineering team

What They're Looking For

They’re looking for a strong Senior iOS Engineer who is comfortable operating autonomously and making decisions without needing a large team around them.

You’ll ideally have:

• Strong commercial experience with Swift
• Experience with SwiftUI and/or UIKit
• Strong API integration and backend service experience
• Good engineering fundamentals around architecture, testing and application quality
• Experience working closely with Product and Design
• A genuine interest in understanding customers and using data to improve the product

Experience with consumer apps, e-commerce or membership/subscription products would be a bonus, but isn't essential.

Why This Role?

Real ownership: You’ll be the senior iOS specialist and have meaningful influence over the direction of the app.

Product influence: You’ll work closely with Product, UX and Engineering leadership rather than simply implementing predefined tickets.

Consumer impact: You’ll be building an app that directly influences how customers discover, engage with and purchase products.

Hands‑on: This is a genuine IC role where you’ll combine strategic input with plenty of hands‑on engineering.

Benefits: Private medical insurance, 25 days holiday plus your birthday, flexible bank holidays, enhanced parental leave and a generous employee product/membership package.

If you’re a Senior iOS Engineer looking for more ownership over both the technology and the product, I’d be keen to tell you more.

Please note: this role requires 3 days per week in the London office.
