Summary
What you’ll impact
The Senior Backend Engineer is responsible for designing, building, and operating the core services that mint, custody, and settle tokenized equities on blockchain platforms. The role uses Go, Python or Java with Kubernetes, Kafka, and PostgreSQL to build scalable distributed systems. Key deliverables include implementing end-to-end tokenization workflows, integrating smart contracts and on-chain settlement with traditional brokerage and ledger systems, and ensuring idempotent, audit-ready processing of financial transactions. The engineer collaborates with product, compliance, legal, and platform teams, leads design reviews, and mentors engineers to raise the technical bar.
Responsibilities
What you'll do
- 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
- Raise the technical bar through design reviews, code reviews, and hands‑on mentorship
Requirements
What you’ll bring
- 5+ years of professional software engineering experience, including a track record of delivering large-scale distributed systems in production
- Expertise in backend development with Go, Python, or Java, and deep familiarity with cloud-native architecture (Kafka, Postgres, Kubernetes, or equivalents)
- Strong instincts for correctness-critical systems - idempotency, reconciliation, and reasoning carefully about failure modes when money is at stake
- 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
- Based in either Menlo Park, Toronto or New York City offices, with in‑person attendance expected at least 3 days per week
