Senior iOS Engineer - SEO Product

We’re looking for a Senior iOS Engineer to help build mobile products that enable more people to discover Wise organically.

This is a hands-on product engineering role in our SEO Product team. We own mobile products that support organic growth, starting with the Wise Currency Converter app developing it into a best in-class travel money companion.

You’ll work closely with product, design, analytics, marketing and engineering from the earliest stages of an idea. We want someone who is comfortable shaping what we build, making technical decisions, and taking ownership from concept through to launch and iteration.

The SEO Product team is working towards an ambitious goal: making customer acquisition eventually free. We’re building products that help millions of potential customers discover Wise organically and make better decisions about their money.

What will you be working on?

Leading the rebuild and modernisation of the Wise Currency Converter app

Architecting and building new mobile products from the ground up

Working closely with Android engineers to build products across both platforms, maintaining a high bar for quality and keeping core features and customer experience aligned

Working closely with product managers, designers, analysts, and other engineers to shape ideas, define requirements, and turn them into simple, high-quality customer experiences

Owning iOS development end-to-end, from technical design through implementation, release, and iteration

Own the observability and reliability of the app, including incident management and working hours support

Making architecture decisions and helping define APIs where needed to support product development

Providing technical guidance through thoughtful code review and collaboration

Contributing to a strong engineering culture through knowledge sharing and high standards for quality, delivery, and maintainability

Mentoring engineers in the team and contributing to our engineering hiring process

What do you need?

Strong experience building and shipping iOS applications in Swift and Swift UI

Experience owning technical decisions and designing architecture for mobile products

Ability to take ambiguous product ideas and turn them into clear technical plans and incremental milestones

Strong product judgment, with the ability to use customer insight and data to inform decisions and challenge assumptions

Experience working closely with cross-functional partners such as product, design, analytics, and backend engineering

Commitment to writing testable, maintainable code and holding a high bar for engineering quality

Experience with software architecture patterns commonly used in iOS development

Understanding of REST API design, including the ability to help shape API contracts where needed

Confidence working autonomously and taking ownership of delivery end-to-end

Strong communication skills, including the ability to explain technical concepts clearly to non-technical audiences

Ability to produce clear technical documentation and diagrams

It would be a bonus if you also have:

Experience with CI/CD tooling such as GitHub Actions

Experience with observability tooling and practices

Experience working with experimentation and using product signals to guide iteration

Experience building accessible, high-quality mobile experiences

Interest in AI-assisted coding tools such as Cursor or Claude Code

Experience collaborating closely with Android engineers on parallel mobile product development

We don’t expect you to tick every box. If this role excites you, we’d still love to hear from you.

What the first six months in this role will look like:

You’ve onboarded successfully and built a strong understanding of your team, squad, guild, and how you can contribute

You’ve developed a good understanding of Wise, the fintech space, and how our product and engineering culture works

You’ve made strong progress on the rebuild and modernisation of the Currency Converter app, with a clear path towards launch

You’ve started owning technical decisions and delivery for iOS work in the team

You’ve gone through two quarterly planning cycles and contributed ideas that help shape the future of the product area

You’ve contributed to hiring interviews

Why this role is exciting

This is a rare opportunity to own an area from the ground up.

You won’t just be implementing tickets in an established mobile surface. You’ll help rebuild an existing product, shape new app ideas, influence what gets built, and take real ownership of iOS development in a team that sees mobile products as a meaningful lever for organic growth.
