About The Position

Cronos Labs is building the consumer trading app for the next generation of retail traders. We are not building another crypto product. We are building the one-stop-shop for trading: stocks, crypto, sports outcomes, and prediction markets, all in one mobile-first app, backed and powered by the trust and infrastructure of Crypto.com. This is not an ecosystem play. This is not a general-purpose blockchain story. This is a consumer product with a clear value prop: One balance. Every market. More buying power. We are looking for a CTO who has built this movie before. Someone who understands the full technical stack required to build a high-performance trading venue: from blockchain infrastructure and smart contract architecture, to matching engines and mobile apps, to the regulatory and integration complexities of tokenized real-world assets. Someone who can lead a globally distributed engineering team through a major pivot and ship at velocity. Someone who will be in the trenches with us. The CTO will be the architect of how we build. You will own the entire engineering organization: blockchain infrastructure, smart contract development, mobile (iOS/Android), web, and backend systems. You will shape the technical strategy, drive engineering culture, and be accountable for shipping a world-class trading platform.

Requirements

12+ years in engineering with at least 5 years in VP/CTO/Head of Engineering roles at high-growth companies.
Trading systems background. You have built or led engineering teams that shipped perpetuals, spot trading, order matching, or derivatives infrastructure. You understand the mechanics of a trading venue: order books, margin systems, liquidations, risk engines.
Blockchain/DeFi depth. You have hands-on experience with EVM-based smart contracts (Solidity), DeFi protocols, and onchain infrastructure. You understand protocol design tradeoffs, bridge security, and the nuances of token standards.
Mobile-first consumer product experience. You have shipped mobile apps at scale, ideally in fintech, trading, or gaming contexts. You understand the realities of Android-dominant emerging markets.
Cross-functional engineering leadership. You have managed teams spanning blockchain, backend, and mobile. You know how to align disparate technical disciplines around a unified product vision.
Sports betting or prediction markets familiarity. You understand how sportsbooks operate (vig, odds, early exit), or have built prediction market infrastructure. You get the mental model of "exit anytime" vs. traditional binary outcomes.
