You will lead technically complex projects end to end in a high-stakes, 24/7 environment, mentor others, and define architecture with a strong emphasis on correctness, security, and scalability.

• Expertise in backend development with Go, Python, or Java, and deep familiarity with cloud-native architecture (Kafka, Postgres, Kubernetes, or equivalents)

• Demonstrated ownership of ambiguous, cross-functional projects, with the judgment to make tradeoffs and drive alignment
• Experience mentoring engineers and influencing technical direction beyond your own projects
• Working knowledge of blockchain fundamentals - EVM, smart contracts, wallets, on-chain settlement - or a strong appetite to go deep quickly

• Design, build, and operate the backend services that mint, custody, and settle tokenized equities across leading blockchains, with correctness and auditability as hard requirements
• Own large, technically complex projects end to end - design, implementation, rollout, and operating what you ship in a 24/7 system
• Build the connective tissue between traditional market infrastructure (brokerage, ledgers, corporate actions) and on-chain systems, including smart contract integrations, chain indexers, and DEX trade flows
• Partner with product, compliance, legal, and platform teams to turn regulatory constraints into workable system design
