Role
Who you are
- 8+ years of experience in iOS development
- 2+ years of experience as a Technical Lead
- Strong expertise in Swift, with hands-on experience in app development using either UIKit or SwiftUI, with a preference for SwiftUI
- Skilled in working closely with various stakeholders including Product, Design, and fellow engineers to align objectives and drive successful outcomes
- Strong experience with leading, developing and delivering complex projects
- Worked in a high growth start-up environment or product focused environment
- Experience mentoring and guiding more engineers with a range of experience
What the job involves
- Lead engineers in a product team enabling a smooth app experience for tens of thousands of policies, ensuring that we provide customers with affordable, instant, and inclusive insurance
- Manage and execute ambiguous technical solutions with appropriate sense of urgency to deliver impact to the business
- Create and promote efficiency and speed within the team by improving existing solutions and developing new ones
- Partner with stakeholders to understand requirements, constructively challenge assumptions, suggest alternatives, and deliver functionality iteratively
- Mentor engineers from Junior to Senior levels of experience, supporting their development through feedback and sharing opportunities
- Work closely with the EM to champion and roadmap technical debt investment
- Ensure alignment between iOS and Android platforms by overseeing project delivery, identifying cross-platform blockers early, and facilitating consistent implementation across both platforms
- Our Tech Stack:
- SwiftUI for new features (approx. 90% of the app)
- Modular architecture using local Swift packages
- Automated testing: unit tests, snapshot tests, and UI tests
- Bitrise for continuous integration
- Fastlane for TestFlight and App Store deployments
- SwiftLint, SwiftFormat, and Danger for automated code styling and checks
- We use Tuist to help us manage our modular architecture and speed up our builds
Application process
- Initial call with Tech Talent Acquisition team via Zoom (30-45 mins)
- A take-home assessment (several days at your discretion) which will be reviewed by our Engineers
- Follow up technical interview with our Engineers to walk us through your take-home task and questions around your past experience and projects via Zoom (90 mins)
- A culture & past experience interview with one of our Engineering Managers to check that your ways of working aligns with our processes, mission and values (1 hour)
- We’ll let you know if you’re invited to an interview or not. But, as a small team with a lot of applications to consider, we can’t give individual feedback on each application

Our take
For many ordinary people, insurance can be inaccessibly expensive. Marshmallow solves this problem by using data and technology to offer fairer access to products like insurance and financial support, starting with coverage for car and van owners.
Traditional providers often rely on broad population averages, meaning individuals are frequently overcharged based on age, nationality, or background. Marshmallow takes a different approach, leveraging proprietary tech to deliver personalise, more accurate quotes in minutes. This has led to better rates for customers and a surge of positive reviews and recognition since the company's launch.
Now operating as a fintech scale-up, Marshmallow is expanding its reach beyond just vehicle insurance. The company is also exploring areas like home insurance and wider financial services, with the aim of supporting those who are often left out of traditional systems. Having achieved unicorn status and doubled its profit since 2023, Marshmallow is well-positioned for this next chapter.
