Staff / Senior Staff Software Engineer, Mobile Growth

As a Staff or Senior Staff Software Engineer on OKX's Mobile Growth team, you own the client-side architecture for new user acquisition, referral and virality mechanics, and the reward and conversion funnels that drive growth for millions of users. This is not a feature delivery role. You bring deep expertise in mobile attribution, from MMP design and evolution through anti-fraud, channel revenue sharing, and ROI evaluation, and you know how to turn attribution data into decisions. 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 do

• Own the client-side architecture for core growth conversion flows including new user acquisition, referral and virality loops, reward mechanics, and activity-driven engagement systems.
• Design and evolve the mobile attribution system, including MMP integration, attribution modelling, and the application of attribution data across anti-fraud, channel revenue sharing, and ROI evaluation scenarios.
• Build and optimise growth infrastructure including funnel instrumentation, experiment frameworks, and acquisition loops that directly serve the mobile user base.
• Collaborate closely with Product, Business Development, and local market teams to translate commercial goals into concrete, data-backed engineering proposals.
• Drive technical decision-making on growth infrastructure, articulating trade-offs clearly and defending or revising positions based on evidence.
• Apply AI coding tools actively in your workflow to build and maintain repeatable personal AI development workflows, not just for code generation.
• Mentor engineers on the team and help establish a culture where engineers bring solutions, not just responses.

What you bring

• 8+ years of software engineering experience with a track record of shipping production-quality systems at scale.
• Deep familiarity with new user growth, referral and virality mechanics, activity and reward systems, and the client-side architecture behind core business conversion flows.
• Strong expertise in mobile attribution design and evolution, with hands-on experience using attribution platforms and solutions, and proven ability to drive attribution data into anti-fraud, channel revenue sharing, and ROI evaluation applications.
• Proficiency in AI-assisted development, able to independently build and maintain personal AI engineering workflows, not just use AI tools ad hoc.
• Data instincts: you think in funnels, know how to instrument what matters, and use metrics to drive decisions.
• An outspoken and proposal-driven approach, coming to the table with a point of view, pushing back when you disagree, and bringing data and a counter-proposal rather than just flagging concerns.
• Strong cross-functional communication skills, comfortable working with Product, Business Development, and local markets to align on goals and hold the line on engineering quality.

Nice to have

• Mobile development experience in iOS (Swift or Objective-C) or Android (Kotlin or Java), or backend experience building growth systems that serve mobile apps directly.
• Depth in MMPs such as AppsFlyer, Adjust, or SKAdNetwork.
• Experience building referral systems, k-factor mechanics, or anti-fraud layers.
• A/B experiment framework ownership at meaningful scale.
• ASO operational experience with App Store Connect or Google Play Console.
• Background in fintech, crypto, or regulated consumer financial products.
• Experience operating across APAC, EEA, or US markets.

What we offer

• Competitive total compensation package
• L&D programs and education subsidy for your growth and development
• Various team building programs and company events
• Wellness and meal allowances
• Comprehensive healthcare schemes for employees and dependants
