APM Full-Stack Engineer (Java, .NET, & Frontend)

Open 54d

Core Job Responsibilities

A. APM Agent Development & Maintenance (Backend Focus)

Platform Expertise: Design, develop, and maintain APM agents and instrumentation for both Java (JVM-based) and .NET (Core and Framework) applications.

Performance Engineering: Instrument core application code to capture metrics, traces, and logs with minimal overhead, focusing on deep-dive component monitoring (DDCM), transaction profiling, and database query tracing.

Cross-Language Support: Troubleshoot and resolve complex performance issues in mixed-technology environments where Java and .NET services interact.

Deployment and Service Management: Configure and manage the deployment of agents as system services (e.g., using NSSM, WinSW, or systemd) and troubleshoot installation issues, including security protocols like TLS/SSL.

B. Frontend Development & Visualization (User Focus)

Data Presentation: Develop and enhance the user interface (UI) and user experience (UX) for the APM platform's dashboards and data visualization tools.

Real User Monitoring (RUM): Implement and optimize Real User Monitoring (RUM) agents to capture client-side performance metrics, including page load times, AJAX calls, and JavaScript errors.

Full-Stack Tracing: Ensure seamless correlation between frontend RUM data and backend Java/.NET transaction traces to provide end-to-end visibility.

Web Performance Optimization: Optimize the frontend application for maximum speed, scalability, and cross-browser compatibility, often dealing with large data sets and complex charts.

C. Monitoring, Alerting, & Operations

Pipeline Management: Work with data pipelines (e.g., Kafka, Elasticsearch) to ensure the efficient ingestion, processing, and storage of high-volume telemetry data (metrics, logs, traces).

Alerting and Triage: Develop and maintain alert rules, thresholds, and anomaly detection models based on critical business and technical metrics (e.g., latency, error rate, throughput).

Collaboration: Act as the subject matter expert (SME) for APM, collaborating with DevOps, SRE, and development teams to diagnose production incidents and define service level objectives (SLOs).



Requirements

Required Skills and Qualifications

A. Core Programming & Frameworks

Java APM: Deep experience with Java, Golang, and JVM internals, along with frameworks such as Spring Boot or Quarkus. Knowledge of Java Agent specifications (e.g., Byte Buddy) is a strong advantage.

.NET APM: Proficiency in C#, .NET Core, ASP.NET, and the .NET CLR, with additional exposure to Golang. Familiarity with Reflection and dynamic code generation for instrumentation.

Frontend: Advanced skills in HTML5, CSS3, and JavaScript (ES6+), with strong expertise in at least one modern frontend framework, preferably React.

Databases: Strong command of SQL (MSSQL, PostgreSQL, Oracle) and a solid understanding of NoSQL concepts for data tracing and querying.

B. APM & Observability Tools

Hands-on experience with leading APM platforms, including New Relic, Dynatrace, AppDynamics, and Datadog.

Familiarity with open-source observability standards, particularly OpenTelemetry (OTEL) and distributed tracing.

Experience working with log aggregation and analysis platforms such as Elastic Stack (ELK) or Splunk.

In-depth understanding of HTTP protocols, TLS/SSL security, and network traffic analysis for troubleshooting and optimization.

C. Development & Operational Skills

Version Control: Advanced use of Git and collaboration via GitHub, GitLab, or Bitbucket.

CI/CD & DevOps: Skilled in building and maintaining continuous integration and delivery pipelines using Jenkins, GitLab CI, or Azure DevOps. Proficient with cloud platforms such as AWS, Azure, or GCP.

Troubleshooting: Exceptional analytical and problem-solving skills for identifying and resolving complex inter-service performance issues.

Soft Skills: Excellent written and verbal communication, with the ability to explain technical issues clearly to both technical teams and business stakeholders.
