Role: Senior Java/Scala Developer

Location: NYC, NY | Chicago, IL | Houston, TX (40 miles from PS office)

Experience required: 10+ years

Brief/Additional Information:

We are seeking a seasoned Senior Java/Scala Developer with a deep specialization in high-throughput trading platforms. You will be responsible for designing and scaling microservices that power our real-time execution algorithms, ensuring ultra-low latency, high availability, and strict adherence to risk and regulatory controls.

Domain Requirements:

  • Trading Lifecycle: Deep understanding of the full trade lifecycle (Order Management, Execution, Clearing, and Settlement).
  • Execution Algorithms: Proven track record of building or maintaining algorithmic engines and SOR (Smart Order Routing) systems.
  • Market Dynamics: Understanding of market data structures (L1/L2/L3 books) and regulatory requirements (MiFID II, SEC Rule 606).
  • Java Expertise: Expert-level proficiency in Core Java (v17+ preferred), including advanced multi-threading, concurrency patterns, and the Java Memory Model.
  • Scala Expertise: Hands-on production experience with Scala, including functional programming patterns, immutability, and use of Scala within JVM-based trading systems (e.g., Akka, Play, or hybrid Java/Scala microservices).
  • Microservices Architecture: Extensive experience with Spring Boot, Spring Cloud, and containerization (Docker/Kubernetes). Familiarity with Service Mesh (Istio/Linkerd) is a plus.
  • Messaging & Integration: Hands-on experience with high-performance messaging middleware like Apache Kafka, Solace, or Aeron.
  • Data Systems: Proficiency in low-latency data stores (Redis, Hazelcast) and SQL/NoSQL databases for trade persistence and auditing.
  • Testing & CI/CD: Commitment to TDD/BDD practices and automated pipeline integration (Jenkins, GitLab CI).
