Preferred * Experience with real-time delivery systems - WebSocket fan-out, server-sent events, or pub/sub at scale. * Familiarity with financial platforms, real-time trading systems, or prediction markets. * Experience in a high-growth startup environment where ownership is broad and the technical landscape evolves quickly. Depending on the role, your interview and onboarding experience may include in-person components, such as onsite interviews or Launching into Better: LIVE-a multi-day cultural immersion in New York City for full-time, non-seasonal hires. These sessions are designed to build connection and bring our culture to life, though specific travel and participation requirements will be confirmed based on your role and location. Your recruiter will provide clear guidance at each stage of the process. ## Description * Design, build, and scale distributed systems using Kotlin, Java, and Spring Boot, architecting for the traffic spikes and concurrency demands of a live real-money trading platform. * Own the development and optimization of high-throughput event pipelines using Kafka, including partition strategy, consumer group design, and exactly-once processing guarantees. * Build and tune low-latency data layers across Postgres, Redis, and Redis PubSub - ensuring data integrity, cache coherence, and sub-millisecond read paths under peak load. * Implement and enforce resilience patterns across services - backpressure handling, circuit breaking, idempotent retry logic, and graceful degradation under failure conditions. * Contribute to real-time user-facing systems, solving the fan-out problem for live market updates across tens of thousands of concurrent sessions. * Partner with product and engineering leadership to align technical execution with business priorities - contributing to build vs. buy decisions and long-term platform strategy. * Set and uphold engineering standards for observability, schema evolution, testing practices, and deployment patterns across the team - through code reviews, RFCs, and technical documentation. * Mentor and actively develop junior and mid-level engineers, raising the technical floor of the team through pairing, design reviews, and direct feedback. ## Related Videos - [Microservices architecture as a key element in building trading systems for global finance markets](https://www.wearedevelopers.com/videos/1196-microservices-architecture-as-a-key-element-in-building-trading-systems-for-global-finance-markets) - [Boosting OpenSearch Performance: gRPC Search in Action](https://www.wearedevelopers.com/videos/1935-boosting-opensearch-performance-grpc-search-in-action) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [Building the platform for providing ML predictions based on real-time player activity](https://www.wearedevelopers.com/videos/944-building-the-platform-for-providing-ml-predictions-based-on-real-time-player-activity) - [gRPC Load Balancing Deep Dive](https://www.wearedevelopers.com/videos/1576-grpc-load-balancing-deep-dive) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [How Much FAANG Companies Actually Pay Software Engineers in 2025](https://www.wearedevelopers.com/magazine/230-how-much-faang-companies-actually-pay-software-engineers-in-2025) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs)
