We are looking for a Senior Staff Mobile Engineer to join our OEX Mobile Growth team — a pure mobile team sitting at the intersection of engineering rigour, consumer growth craft, and product instinct. This is not a feature delivery role. You will 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.
You bring deep expertise in mobile attribution — from MMP design and evolution through to 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.
- Own the client-side architecture for core growth conversion flows — 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 — not just for code generation, but to build and maintain repeatable personal AI development workflows.
- Mentor engineers on the team and help establish a culture where engineers bring solutions, not just responses.
- 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 — hands-on experience with attribution platforms and solutions, and proven ability to drive attribution data into anti-fraud, channel revenue sharing, and ROI evaluation applications.
- Proficient 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.
- Outspoken and proposal-driven — you come to the table with a point of view, push back when you disagree, and bring data and a counter-proposal rather than just flagging concerns.
- Strong cross-functional communication — comfortable working with Product, Business Development, and local markets to align on goals and hold the line on engineering quality.
- Mobile development experience in iOS (Swift/Objective-C) or Android (Kotlin/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 (App Store Connect, Google Play Console).
- Background in fintech, crypto, or regulated consumer financial products.
- Experience operating across APAC, EEA, or US markets.
- 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
- More that we love to tell you along the process!
