React Native Engineer (Contract)

What’s Yonder?

“It's as if Time Out, Amex and Monzo had a baby” - Will T, Yonder Member

We’re building the financial membership of the future. One that works for how you live now. Not how your parents banked in the ‘90s.

Yonder combines credit and debit in one membership, designed to be fair, flexible, and actually enjoyable to use. No confusing terms. No dusty points system. Just rewards that actually feel rewarding - from bao to beer to a boarding pass.

We raised £23.4M in September 2024 to grow the team, launch even better rewards, and expand beyond the UK. If that sounds good to you, you’ll probably like it here. 🎉

Sounds cool. What’s my part in this?

Over the last year we've added a debit card, a free membership tier, hundreds of new independent partners around the country, countless product improvements and our personal favourite, Yonder Flights, a new way to use Yonder points on any flight with any airline globally. We've maintained a 4.5 TrustPilot rating and our customers really love us (and we love them back... hi!).

We’re looking for a React Native Engineer to join our growing team of frontend engineers on a 3 month contract. The frontend team build our beautifully designed Android and iOS applications in React Native and our web-app in Next.js. We’re seeking someone passionate about executing the minute-design details that make every experience wonderful.

You’ll get to work with the wider engineering team on influencing how we build the financial membership of the future, you’ll be deeply involved in crafting the direction of the product roadmap and invest heavily in creating delightful customer experiences .

You'll be joining a small engineering team with deep end-to-end ownership over their own development work and the technical direction of our product. As a small team, the work you do has a huge impact and you’ll get to shape the future of engineering at Yonder.

What you’ll do

• Develop our iOS and Android mobile apps: You’ll be responsible for delivering on our product and design vision into our iOS and Android mobile apps. Using React Native you’ll be adding our latest features, iterating on our existing ones and ensuring a magical experience for all our members.
• Build out our web-app in Next.js : With a freshly launched web app in Next.js, you’ll be building on the foundations the team has in place, and bringing the latest technologies to ensure we can deliver an experience on the web that rivals our mobile apps.
• Closely collaborating in cross-functional squads : Work incredibly closely with our product and design teams to create magical moments across all our frontend clients that elevate us above a typical credit card.
• Full lifecycle ownership : Own the development lifecycle from the ground up—defining stories, overseeing testing, and orchestrating deployments to ensure our products get into our members hands as quickly as possible.
• Leading technical discussions : Lead the charge in pivotal technical discussions, influencing decisions on architecture, tool selection, and methodologies that push the boundaries of what's possible.
• Mentorship and team leadership : Provide mentorship to the rest of the frontend team, building their technical abilities and knowledge in our various frontend technologies.
• Spotting and driving improvements : Proactively identify inefficiencies, bottlenecks, or opportunities to improve our tools, workflows, and processes. Take ownership of seeing these improvements through from idea to implementation, ensuring they deliver lasting value for the team and the product.

You're a great fit if you

✅ Know React Native inside-out: You’ve used React Native to build high-grade apps that have been shipped into users hands. You can push the boundaries of what is possible with technologies like Reanimated to create magical moments for everyone.

✅ Skilled in Next.js with Server-Side Rendering: Experienced in building robust web applications using Next.js, particularly with server-side rendering techniques.

✅ You sweat the small stuff: Attention to detail of the tiny things matter to you. You go above and beyond to execute on all the small design details that add to an incredible experience. You are a partner to the design team and strive to make every interaction special.

✅ Cross-platform expertise: Making it work on one platform isn’t good enough. You strive for a delightful experience that works across iOS and Android and accounts for each platforms nuances.

✅ Familiarity with design systems: You’ve used a design system in the past, you know when it makes sense, but also know when to throw it out the window and build something truly special.

✅ Think like a product engineer: You don’t just write code — you solve problems. You understand the user requirements and the “why” behind your work, delivering solutions that meet the need in the most effective, elegant way. The job isn’t done when the code ships, but when the problem is truly solved for the user.

✅ Thrive in ambiguity: Thrives in uncertain environments, effectively setting directions and navigating challenges with confidence when there are so many unknowns.

✅ Own quality through automated testing: You take full responsibility for ensuring your code is reliable by writing thorough automated tests. You see testing as part of building, not an afterthought, and actively involve the wider squad when collaboration or shared test coverage is needed to guarantee a rock-solid experience.

You won’t be a great fit if you

👎 Prefer working in large, structured teams with well-defined processes over fast-moving, evolving environments.

👎 Focus solely on technical perfection without balancing customer impact and business needs.

👎 Struggle with taking ownership or making decisions in situations where the path forward isn’t fully defined.

👎 Are uncomfortable diving into areas outside your core expertise (e.g., infrastructure, DevOps, or unfamiliar parts of the stack).

👎 Seeking a Strict 9–5: Our pace and priorities often require flexibility beyond standard hours, especially when shipping on tight deadlines.

What’s it like working at Yonder?

🏢 We’re office-first, but remote-friendly in the Frontend squad

While the rest of the company is office-first, our Frontend team is remote-friendly. We’re open to both hybrid and fully remote setups (UK-based), with hybrid team members coming into our Hoxton office — complete with a terrace, breakfast, coffee (from a barista), dogs, beer taps, and plenty of comfortable space — at least 3 days a week, with everyone in on Mondays.

🤍 We take a values-led approach

Our principles are incredibly important to us, so we recommend you check them out here: Our DNA

📚 We take development really seriously

We have a pretty structured process for progression, with fortnightly one-on-ones and quarterly peer perspectives. We also take some time at the end of each week to reflect and celebrate what we’ve learned and achieved.

What’s the interview process like?

We take the candidate experience really seriously, so we’ve made the process as transparent as possible. We also promise to be super responsive, and will never leave you wondering where you stand for weeks on end.

Here’s how it works:

Stage 1: Intro call (30 mins)

You will have an initial call with Jas Hayer to find out more about you and to tell you more about us.

Stage 3: System design task (90 mins)

You’ll be given a task to create a high-level system design for a responsive web application, detailing how the frontend will interact with backend services. We'll deep dive into your technical experience through designing a system on a whiteboard.

Stage 4: Values interview (30 mins)

We want to learn more about how you work - we’ll ask you questions related to our principles ( Our DNA ). This stage you'll meet with Harry Jell (CTO & Co-founder).

Stage 5: We’ll also do a reference check - ideally with a previous manager on the phone

Stage 6: Offer If everyone’s happy, we’ll make you an offer to join us - YAY! 🎉 We hope to always give you a decision between each stage within 24 hours (where possible).

Other things to know:

• We love closing the feedback loop at Yonder. You can expect specific feedback on our decision from Stage 2 onwards, and you can always ask for more.
• We must complete right to work & criminal, politically exposed persons, and default to credit notice background checks for every new Yonder-er for compliance purposes because we handle sensitive customer data.
• We also do reference checks, ideally with your most recent manager on the phone.
• We like to move quickly at Yonder, so we will be ready to onboard you once the above checks are complete - the entire process can take between 2 - 6 weeks.

🌈 We know that diverse teams build better products. If you’re from an under-represented community, we’d especially love to hear from you.

👉 Even if you don’t feel 100% qualified, please do apply anyway. Your attitude and desire to grow are just as important as your experience.
