- 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.
