Job summary

EPAM Systems is seeking a Senior Engineer to join the team building the Real-Time platform by aggregating telemetry data across services and instruments. You will design and implement end-to-end observability, latency-sensitive data paths, and synthetic monitoring across global sites.

Responsibilities include building data-pipeline components, developing aggregation algorithms, and extending telemetry pipelines. Strong knowledge of C++, Go, or Rust, plus Python/Java/TypeScript, is required.

Qualifications

• 7+ years of hands-on software engineering experience building data-pipeline applications, including metrics aggregation, distributed tracing, or real-time streaming.
• Background in latency-sensitive or market data systems.
• Proficiency in at least one systems-level language (C++, Go, or Rust) and one scripting/application language (Python, Java, or TypeScript).
• Understanding of C++ to comprehend existing applications.
• Background in building and operating custom synthetic monitoring solutions at scale, including lightweight agents distributed across geographically diverse sites.
• Familiarity with OpenTelemetry SDKs, collectors, and schema conventions for instrumentation and telemetry export.
• Skills in cloud-native, containerized, and Kubernetes environments, including deploying and operating services at scale.
• Proficiency with API- & GitOps-based workflows, config-as-code, and CI/CD pipelines for infrastructure.
• Showcase of a strong analytical mindset for modeling complex distributed-system behaviors and understanding customer impact.
• Capability to communicate effectively across squads and simplify system performance concepts for broader stakeholders.
• Proficiency in English at a B2+ level.

Responsibilities

• Build and maintain the application components that aggregate, correlate, and present observability data from individual services into unified, end-to-end views of the Real-Time platform.
• Implement customer-centric aggregation and hotspot detection algorithms that reflect timeliness, completeness, accuracy, and stability of market data across the Real-Time estate.
• Develop and extend telemetry pipelines that ingest, transform, and route metrics, traces, and logs from distributed services into a coherent observability layer.
• Design and build custom synthetic monitoring agents deployed across hundreds of global sites to continuously measure customer experience of Real-Time data from the edge.
• Implement GitOps/API-driven workflows for observability assets to ensure consistent deployment, versioning, and promotion through build pipelines.
• Collaborate with squads to integrate observability instrumentation into applications throughout Dev, Test, PPE, and Prod environments.
