Mobile UI Designer
BJAKBJAK is looking for a Mobile UI Designer to shape the next wave of money apps. The company started in 2019 with a mobile-first online insurance platform and has grown to become a leading online insurer in Southeast Asia. Now BJAK is expanding into more finance-focused experiences like spending, saving, investing, exchanging and traveling, with a clear aim: help people get more from their money every day. Teams are spread across the globe with more than 20 nationalities, and they value designers who bring passion and high-quality outcomes. The role is remote, with a preference for candidates based in the Netherlands as the company hires specifically for that market.
As a Mobile UI Designer, you’ll craft elegant, intuitive and high-performing mobile experiences for BJAK’s AI Neobank and related financial products. This is for someone who loves building interfaces that feel effortless, responsive and refined. You’ll partner with engineers and product managers to deliver experiences that are used daily by millions of people.
If you enjoy turning complex financial workflows into clean, approachable interfaces and you thrive in a team that collaborates across time zones, this could be the right next step for you.
Daily craft in the mobile UI studio
In this role, you’ll design interfaces for both iOS and Android, shaping the visual language and interaction patterns that users touch every day. You’ll create wireframes, user flows and prototypes, then translate them into production-ready UI that keeps a crisp, consistent look across the product suite. The work spans insurance, payments, claims, investments and other financial services, so you’ll be expected to uphold a high standard of usability while aligning with platform guidelines. A key part of the job is building and maintaining a mobile design system with reusable components, and partnering closely with developers to ensure what’s built matches the design with pixel-perfect accuracy. You’ll continuously improve interfaces by applying findings from analytics, usability tests and product feedback, making sure experiences stay usable and accessible across devices, screen sizes and operating systems.

Comfort using design tools and processes around design systems, including Auto Layout for responsive layouts.
Experience creating and testing interactive prototypes to demonstrate flows end-to-end.
Knowledge of both iOS Human Interface Guidelines and Material Design conventions.
A mobile-first mindset with a track record of delivering polished interfaces and refined interactions.
Ability to spot and fix small UI inconsistencies before users notice them, with a focus on accessibility, responsiveness and performance.

Tips to stand out for this role
Lead your resume with your strongest mobile UI work and place your portfolio front and centre. Make sure it showcases mobile screens that reflect fintech or financial services, and that the projects demonstrate the full spectrum from concept to pixel-perfect detail. Highlight specific outcomes or metrics where you can, especially any examples where your design improved usability or engagement on a mobile banking or payments app.
When you discuss your must-haves, point to concrete work in Figma and interactive prototypes. Include a short case study from your portfolio that walked through a financial flow you redesigned, the decisions you made around typography and spacing, and how you aligned the UI with iOS or Android guidelines. Explain why those choices improved usability and how accessibility considerations were baked in.
For interviews, be prepared to talk through how you translate complex financial workflows into simple, intuitive screens. Describe your approach to building and using a design system, and how you validate designs with analytics or usability findings. You may be asked to reflect on a design task or present a component from your design system, so rehearse a clear rationale for your decisions and trade-offs.
Ask a smart question about how the team ensures consistency across devices and platforms, how the design system is governed and evolved, and how remote collaboration with engineers is organised to keep delivery smooth and predictable.
