Job description

About the role

The team in Bengaluru owns the Observability platform that underpins Tesco's engineering organisation. We are responsible for three production-grade tools — Splunk, New Relic, and Runscope — and act as the platform team that enables hundreds of engineering and infrastructure teams to adopt observability best practices at scale.

As an SE3 in this team, you will be a senior technical owner across all three tools. You will not just operate the platform — you will evolve it: driving cost efficiency, improving security posture, rolling out new capabilities (including AI-powered features in New Relic), and enabling infrastructure teams to onboard via OpenTelemetry. You will work closely with the Security team, set SLI/SLO standards for the platform, and mentor junior engineers.

This role suits someone who is equally comfortable with deep technical work and cross-team collaboration, and who takes ownership of outcomes, not just tasks.

You will be responsible for

Splunk — Platform Operations & Cost Governance

• Partner with the Security team to onboard new data sources — validating log formats, agreeing ingestion scope, and ensuring data pipeline stability throughout the onboarding process
• Own data ingestion cost governance: analyse ingestion volumes by team and source, identify waste or noise, and implement controls (event filtering, aggregation, summary indexing) to keep costs within budget
• Define and enforce ingestion standards — teams should ingest only what is needed for their alerting, compliance, and debugging use cases
• Monitor and maintain platform SLIs/SLOs: indexing throughput, search latency, forwarder health, and data availability
• Drive Splunk security improvements: access control reviews, index-level permissions, audit log monitoring, credential hygiene, and alignment with Tesco security policies
• Respond to and resolve platform incidents; maintain runbooks and capacity forecasts

New Relic — Rollout, AI Features & Cost Control

• Lead the rollout of New Relic Anomaly Detection to engineering teams — running discovery workshops, configuring baselines and sensitivity settings, and validating signal quality before handover
• Explore, pilot, and implement New Relic AI features — including AI-assisted alerting, applied intelligence, and MCP (Model Context Protocol) integrations — and build a roadmap for wider adoption
• Manage data ingestion within contracted limits: identify high-volume sources, work with teams to tune instrumentation, and implement ingest drop rules or sampling strategies as needed
• Monitor and maintain New Relic platform SLIs/SLOs: agent coverage, ingest pipeline health, alert reliability, and dashboard availability
• Drive New Relic security improvements: user access governance, API key lifecycle management, SAML/SSO configuration, and audit log review
• Act as the primary escalation point for teams consuming New Relic — supporting onboarding, troubleshooting instrumentation gaps, and advising on NRQL-based alerting and dashboarding

Runscope — Ongoing Operations & Security

• Ensure Runscope API monitoring operates within defined SLIs/SLOs: test pass rates, alert latency, and integration uptime
• Work with teams to review and improve existing test suites — coverage gaps, flaky tests, and alerting thresholds
• Drive Runscope security improvements: access control reviews, token rotation, integration security, and alignment with Tesco security standards
• Support teams in extending API monitoring coverage as new services are onboarded

OpenTelemetry — Infrastructure Onboarding Enablement

• Design and maintain OTel Collector configurations for infrastructure teams — covering metrics, traces, and logs across on-prem, cloud, and hybrid environments
• Build deployment patterns (Helm charts, configuration templates, automation scripts) that make it easy for infra teams to onboard self-sufficiently
• Manage OTel pipelines routing telemetry to Splunk, New Relic, or both — implementing processors, filters, and exporters as needed
• Document onboarding guides and runbooks; run enablement sessions with infrastructure teams
• Troubleshoot telemetry gaps, data quality issues, and collector performance problems

Platform Governance & Mentorship

• Maintain SLI/SLO definitions and dashboards for all three observability tools; report platform health to the Engineering Manager
• Contribute to security reviews across Splunk, New Relic, and Runscope — proactively identifying gaps and owning remediation
• Mentor SE1 and SE2 engineers: code and configuration reviews, pair debugging, structured feedback aligned to their development plans
• Represent the Observability team in architecture forums, vendor conversations, and cross-functional planning
• Assist the Engineering Manager with hiring: technical screen design and participation in interview panels

You will need

• 8+ years in a DevOps/SRE
• Expertise in Node JS Development
• 5+ years hands-on with Splunk: SPL query development, forwarder/indexer management, data inputs, and cost/volume management
• Demonstrable experience with New Relic: APM, infrastructure monitoring, NRQL, alerting policies, and agent deployment at scale
• Solid understanding of API monitoring principles; experience with Runscope or comparable tools (Postman Monitors, Checkly, APIMetrics)
• Hands‑on experience deploying and configuring the OpenTelemetry Collector — pipelines, exporters, processors
• Strong scripting ability in Python and/or Bash for automation, configuration management, and data transformation
• Experience with log parsing and structured/unstructured data ingestion including regex field extraction
• Ability to manage and optimise observability costs — ingestion controls, data tiering, noise reduction
• Clear communicator: able to document technical decisions, run enablement sessions, and influence teams you don't directly manage

Preferred

• Splunk Certified Power User, Admin, or Architect certification
• New Relic Certified Performance Pro or equivalent
• Familiarity with New Relic AI features: Applied Intelligence, anomaly detection, NR MCP integration
• Experience with Kubernetes/container observability — OTel sidecar/daemonset patterns, Prometheus‑to‑OTel pipelines
• Background with mainframe or legacy infrastructure log forwarding (IBM z/OS, MQ)
• Experience in retail, e‑commerce, or other large‑scale, high‑availability consumer technology environments
