About the role

Staff Engineer focusing on the Risk Platform who will own core risk services, design distributed real-time risk systems, and lead technical initiatives end-to-end while mentoring other engineers.

Responsibilities

  • Lead the technical direction of core risk services, including real-time detection, decision engines, and risk tooling, ensuring they’re reliable, scalable, and cost-efficient under high-throughput and low-latency constraints.
  • Design and evolve distributed, event-driven risk systems—including microservices, streaming pipelines, feature stores, and model-serving layers—that support global products and regulatory requirements.
  • Own complex initiatives end to end, from high-level design and technical specifications through implementation, rollout, and continuous improvement.
  • Stay hands-on in code and design, writing high-quality production software primarily in Java and Spring Boot, and leading design reviews, RFCs, and architecture discussions.
  • Partner with the Engineering Manager and Product Manager to shape the roadmap, define technical milestones, and translate business and risk objectives into robust engineering solutions.
  • Raise the engineering bar across the Risk Platform stack by setting standards for code quality, observability, reliability, security, and performance.
  • Improve detection effectiveness by integrating models, rules, and features into production systems, and by designing experimentation and evaluation capabilities with data and ML teams.
  • Drive operational excellence through stronger on-call readiness, incident response, postmortems, SLIs/SLOs, capacity planning, and resilience patterns such as graceful degradation, fallbacks, retries, timeouts, and backpressure.
  • Mentor and uplevel engineers, including senior individual contributors, through technical coaching, pair programming, design guidance, and feedback.
  • Collaborate with platform, data, SRE, security, and product engineering teams to define clear interfaces, SLAs, and ownership boundaries for shared services and infrastructure.
  • Identify and pay down technical debt deliberately, balancing short-term impact with long-term platform health.

Qualifications

  • 10+ years of back-end engineering experience, including substantial experience owning and operating complex distributed systems in production.
  • Deep experience in risk, fraud, fintech, payments, banking, trading, or another high-stakes domain where correctness and reliability are critical.
  • Strong proficiency in Java, including multithreading, high-concurrency patterns, performance tuning, and networked service design across I/O/NIO, HTTP/TCP, and REST.
  • Hands-on experience designing distributed systems, including event-driven architectures, partitioning and sharding, consistency models, caching strategies, and resilience patterns.
  • Proficiency with Spring or Spring Boot and build tools such as Gradle or Maven.
  • Practical production experience with Docker and Kubernetes.
  • Solid understanding of observability and operations, including logging, metrics, tracing, dashboards, and incident management for large-scale systems.
  • Experience leading complex technical initiatives end to end and influencing engineers and stakeholders without relying on formal management authority.
  • Strong communication skills, with the ability to explain complex technical topics clearly to engineers, product managers, and non-technical stakeholders.
  • A bachelor’s degree in Computer Science or a related field, or equivalent practical experience.
