Job Title: Lead Backend Engineer (Java, Digital Assets & Distributed Systems)
Location: New York City (On-site Day 1)
Employment Type: W-2
Role Overview
We are looking for a seasoned backend engineering leader to build and scale high-throughput, resilient platforms at the intersection of traditional financial systems and digital assets. This role demands deep technical expertise, hands-on leadership, and a strong focus on performance, security, and compliance.
Key Responsibilities
  • Build high-throughput, resilient platforms integrating settlement, custody, and digital asset systems with strong focus on performance, reliability, and compliance.
  • Lead and mentor a team of engineers, driving Agile delivery, code quality, and modern SDLC practices.
  • Design and deliver Java (17+) Spring Boot microservices on Kubernetes with resilience patterns (circuit breakers, retries, bulkheads).
  • Develop low-latency APIs (REST/GraphQL/gRPC) with secure auth (OAuth2/OIDC/mTLS) and robust versioning & validation.
  • Implement event-driven architecture using Kafka, applying CQRS/event sourcing and ensuring idempotency.
  • Integrate Web3/Ethereum services, including wallet orchestration and secure key management (MPC/HSM).
  • Enforce security best practices: secrets management, rate limiting, PII protection, and AML/KYC compliance flows.
  • Optimize Oracle databases with strong focus on performance, partitioning, and transactional integrity.
  • Drive CI/CD pipelines (Jenkins/GitHub Actions) with quality gates (SonarQube) and comprehensive automated testing.
  • Establish observability (logs, metrics, tracing) and own SLO/SLA performance targets.
  • Contribute to secure frontend/mobile experiences (React/TypeScript) with device and transaction security controls.
Required Qualifications
  • 8-13 years of software engineering experience with strong backend focus.
  • Proven expertise in Java, Spring Boot, and microservices architecture.
  • Experience building high-volume, low-latency distributed systems.
  • Strong knowledge of API design, event-driven systems, and cloud-native architecture (Kubernetes).
  • Hands-on experience with Kafka, Oracle DB, and performance optimization.
  • Familiarity with security, compliance, and financial systems.
  • Excellent problem-solving, communication, and leadership skills.
Nice to Have
  • Experience in securities/post-trade systems.
  • Exposure to Ethereum, Solidity, or Web3 ecosystems.
  • Experience with MPC, HSM, or digital asset custody platforms.
