About the Role
We are seeking a Senior Software Engineer to support and execute a critical observability migration.
In this role, you will lead the transition of our application and infrastructure telemetry from New Relic to a modern, OpenTelemetry (OTel) Collector‐based architecture.
You will be responsible for re‐instrumenting applications, updating infrastructure manifests, validating telemetry outputs, and ensuring seamless monitoring coverage across our high‐scale ecosystem without compromising operational visibility.
Key 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.
Requirements
Must‐Have
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).
Nice‐to‐Have
Experience operating or configuring OTel Collectors in Kubernetes or containerized environments.
Knowledge of FinOps and cost‐optimization strategies related to telemetry ingestion rates.
Key Deliverables & Success Criteria
Execution:
Successfully updated application instrumentation, validated OTel Collector configs, and verified end‐to‐end telemetry delivery to designated backends.
Documentation:
Updated technical documentation, migration checklists, and runbooks.
Quality & Continuity:
Zero removal of critical monitoring coverage during the migration window, with all pull requests passing automated tests and code reviews.
What We Offer (Contractor)
Contractor agreement with payment in USD.
100% remote work in an international setting.
Access to Argentine public holidays.
Direct involvement in modernizing core platform observability for a high‐growth fintech ecosystem.
Professional development, learning platforms, and referral programs.
