OKX is part of OKG, a group that brings the value of Blockchain to users around the world, through our leading products OKX, OKX Wallet, OKLink and more. About The Opportunity We are looking for a Senior Staff Software Engineer to join the 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 sit upstream of requirements, shape initiatives alongside product and business stakeholders, and own the engineering end-to-end on growth bets that move real metrics for millions of users. The ideal profile combines a solid engineering foundation, hands-on growth experience serving mobile users, and the conviction to bring proposals, not just execute them. What You'll Be Doing Own the full engineering lifecycle of mobile growth initiatives - from shaping the brief with product and business through to production launch and iteration. Build and optimise growth systems - including funnel instrumentation, referral mechanics, acquisition loops, and experiment frameworks — directly serving the mobile user base. Collaborate closely with Product Manager, Business Development, and local market teams across multiple regions to translate commercial goals into concrete, data-backed engineering proposals. Apply AI coding tools actively in your workflow to accelerate development, improve code quality, and bridge across tech stacks where needed. Drive technical decision-making on growth infrastructure, articulating trade-offs clearly and defending or revising your positions based on evidence. Mentor engineers on the team and help establish a culture where engineers bring solutions, not just responses. What We Look For In You 8+ years of software engineering experience with a track record of shipping production-quality systems at scale. Hands-on growth engineering experience — funnel optimisation, experiment frameworks, acquisition or referral systems — in a consumer-facing (ToC) product context. Understanding of mobile users: how they behave, what drives retention and conversion, and how mobile-native growth mechanics differ from web. Actively uses AI tools as a core part of your engineering workflow — not just for code generation, but for building repeatable workflows and bridging across stacks. 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 Manager, Business Development, and local markets to align on goals and hold the line on engineering quality. Data instincts: you think in funnels, know how to instrument what matters, and use metrics to drive decisions. Nice-To-Haves Mobile development experience in iOS (Swift/Objective-C) or Android (Kotlin/Java) — or backend experience building growth systems that serve mobile apps directly (e.g. growth APIs, attribution pipelines, notification infrastructure). Experience with Rust or other systems languages — especially candidates who have recently migrated from mobile-native stacks and are building fluency in backend tooling. Depth in mobile attribution and MMPs (AppsFlyer, Adjust, SKAdNetwork). ASO operational experience (App Store Connect, Google Play Console). Experience building referral systems, k-factor mechanics, or anti-fraud layers. Background in fintech, crypto, or regulated consumer financial products. Experience operating across US, EEA, and APAC markets. A/B experiment framework ownership at meaningful scale.

How we're different We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills. The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences. Come work with us! Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.
