About The Team What You'll Be DoingWhat We Look For In YouNice-To-Haves
The Trading Strategies Mobile Team owns OKX's Trading Bot and Copy Trading experiences across iOS and Android. On the Trading Bot side we build the full suite of strategy bots (Spot & Futures Grid, Spot & Futures DCA, Recurring Buy, Smart Portfolio, Smart Arbitrage, Signal Bot, DCD, and AI-powered bots) that let millions of users automate their trading across spot and derivatives. On the Copy Trading side we let users discover top traders and automatically mirror their positions. It's a large, high-complexity mobile surface built on a shared Rust/UniFFI core, and we're actively moving performance-critical paths to Rust so the logic is shared across platforms. We care deeply about engineering quality. A big, fast-moving codebase demands high standards for architecture, stability, and performance, so we invest consistently in review rigor, knowledge-sharing, and technical training to keep raising the bar. We're also a growth team, working closely with Product and Design to ship new strategies, improve the automated trading experience, and most recently build AI-driven bot experiences. We're at an exciting inflection point, bringing AI into both our product and our engineering workflows. If you're energized by taming complexity at scale, driving technical excellence and business impact in equal measure, and shaping how automated crypto trading works for millions, this is the team to be on.
- Own the technical architecture and delivery of the Android/iOS Trading Bot codebase as your primary focus, while also contributing to Copy Trading as our second core surface, raising code quality, stability, and performance across both and across the flows that create, manage, copy, and follow strategies.
- Lead large-scale technical initiatives end to end, from the Kotlin/Swift-to-Rust/UniFFI migration to modularization and binary-compatibility discipline across the Trading Bot and shared-core repositories, and the work to cut crash, ANR, and startup hotspots.
- Join product requirement discussions, shape well-reasoned technical solutions, and protect product performance, stability, and user experience.
- Partner with product and business to drive the Trading Bot roadmap, from new strategy types to sharing, attribution, and growth features, to AI-powered bot experiences, turning technical leverage into business impact.
- Stay close to industry trends, keep refining the technical architecture, and grow the team's engineering capabilities through training and knowledge-sharing.
- Mentor engineers and lead by influence, lifting the whole team's technical proficiency.
- Lead the team in exploring the integration of AI into business scenarios, driving product and technology innovation.
- Staff/Principal level Android/iOS expertise. 8+ years building and shipping production Android/iOS apps, with deep Kotlin and a strong command of multi-module architecture, dependency and binary-compatibility constraints, and platform performance (ANR, crash, startup, memory).
- A track record of leading mid to large projects end to end. You hold a high bar for architecture and engineering quality, and you've raised that bar on a large, legacy-heavy codebase with results to show for it.
- Technical strategy paired with business sense. You can set technical direction and work with product to turn it into roadmap and revenue. You own outcomes, not just code.
- A trading or fintech background. Client-side experience at a crypto exchange, brokerage, or fintech app, with familiarity in core domains like order placement, market data, and asset management. Automated or algorithmic trading is a strong plus.
- Influence and mentorship. You make the engineers around you better through review, design guidance, and knowledge-sharing, and you build alignment across teams without leaning on authority.
- Cross-language or Rust experience. Rust, UniFFI/FFI, or iOS Swift/Obj-C, and comfort owning a shared cross-platform core.
- Automated-trading domain depth. Hands-on with trading bots, grid or DCA strategies, perpetuals and derivatives, copy or social trading, or market-making and arbitrage, or trading in general.
- AI engineering experience. LLM fundamentals, prompt engineering, RAG, or agent workflows, and an eye for bringing AI into both the product and the engineering workflow.
- Performance and reliability tooling. APM, tracing, and crash or ANR triage at scale.
- Scaled CI/CD. Experience with large monorepo or multi-module release systems, such as MMR-style merge pipelines.
- Client-side team leadership. You've mentored or led a client-side team and can drive cross-team collaboration and technical review.
