Job summary

Darwoft is seeking a Senior Software Engineer to lead a critical observability migration. You will transition telemetry from New Relic to OpenTelemetry across a high-scale fintech infrastructure, updating instrumentation, manifests, and validation processes.

You will validate telemetry outputs, contribute to dashboards and runbooks, and ensure uninterrupted monitoring coverage while coordinating with global teams.

Qualifications

• Proven experience in software engineering with proficiency in at least one modern language (Java, Python, Go, or JavaScript/TypeScript).
• Hands-on experience with OpenTelemetry (OTel) concepts, including distributed tracing, metrics, logs, and OTel Collector configurations.
• Deep experience with cloud observability paradigms and transitioning off legacy platforms like New Relic.
• Solid understanding of HTTP, APIs, environment-based configurations, and reading/modifying complex YAML/JSON manifests.
• Strong background in software testing, debugging, log analysis, and validating high-cardinality telemetry data.
• Familiarity with modern software delivery workflows (Git, PRs, CI/CD pipelines).
• Experience operating or configuring OTel Collectors in Kubernetes is a plus.
• Knowledge of FinOps and cost-optimization strategies related to telemetry ingestion rates is a plus.

Responsibilities

• Migrate existing application instrumentation, tracing, and telemetry configurations from New Relic to OpenTelemetry.
• Update YAML configuration files, environment variables, and deployment manifests according to established architecture standards.
• Execute unit tests and validation suites to verify that telemetry is accurately generated, transformed, and exported to target backends.
• Perform telemetry gap analysis, comparing existing New Relic data against OTel outputs to identify missing traces, metrics, logs, or resource attributes.
• Assist in updating dashboards, monitoring documentation, and troubleshooting guides to reflect the OTel architecture.
• Investigate telemetry collection and export errors, identifying root causes and collaborating with core platform engineers on complex edge cases.
• Maintain clear tracking and reporting of implementation progress, edge cases, and potential migration risks.
