Who We Are
About The Opportunity
We are looking for a Senior Staff Mobile Engineer to join our P2P & Fiat team, where you will own the mobile engineering for OKX’s peer-to-peer trading and fiat payment experiences across multiple markets. This is a high-ownership role sitting at the intersection of mobile engineering and cross-border payments—you will work closely with compliance, legal, and regional business teams to build localised, regulation-aware payment flows for users across Southeast Asia, LATAM, MENA, and beyond.
You bring deep familiarity with P2P trading mechanics, cross-regional fiat payment integrations, and the compliance considerations that govern them. You are also fluent in AI-assisted development and bring the discipline to build, maintain, and continuously improve your own AI engineering workflows.
What You'll Be Doing
- Own the mobile engineering for P2P trading flows, including trading channel mechanics, payment methods, and end-to-end buy and sell transaction journeys.
-
Build and maintain cross-regional fiat payment integrations, including local bank transfers, e-wallets, and third-party PSP integrations across markets such as Southeast Asia, LATAM, and MENA.
-
Ensure mobile payment flows and user data handling comply with local and international regulatory requirements, including KYC tiers, transaction limits, and regional compliance constraints.
-
Collaborate closely with compliance, legal, product, and regional market teams to translate local regulatory requirements into reliable, user-friendly mobile experiences.
-
Drive technical decision-making on payment architecture, clearly articulating trade-offs across delivery speed, maintainability, and compliance.
-
Apply AI coding tools actively in your workflow—not only for code generation, but also to build and maintain repeatable personal AI development workflows.
-
Mentor engineers on the team and contribute to a culture of ownership, technical rigour, and high engineering standards.
What We Look For In You
-
5+ years of professional software engineering experience, including hands-on experience building and maintaining production mobile applications. Level will be calibrated based on technical depth, scope, and demonstrated impact.
-
Proficiency in either iOS development using Swift or Objective-C, or Android development using Kotlin or Java.
-
Solid software engineering fundamentals, including data structures, algorithms, API design, testing, debugging, and system design.
-
Experience delivering reliable mobile features and addressing practical challenges in areas such as performance, stability, architecture, or user experience.
-
Ability to take ownership of engineering work, collaborate effectively with others, and drive solutions from design through production.
-
Good judgment when balancing delivery speed, product requirements, technical quality, and maintainability.
Nice-To-Haves
-
Experience in crypto, fintech, digital payments, or another regulated product environment.
-
Experience building large-scale or multi-market consumer mobile applications.
-
Experience in one or more areas such as mobile architecture, infrastructure, performance, security, or cross-platform development.
-
Practical experience using AI-assisted development tools and validating AI-generated output.
Perks & Benefits
-
Competitive total compensation package
-
L&D programs and Education subsidy for employees' growth and development
-
Various team building programs and company events
-
Wellness and meal allowances
-
Comprehensive healthcare schemes for employees and dependants
