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
Splunk is our established, widely-adopted log management and SIEM platform. Your focus here is on sustaining reliability, controlling costs, and improving security — not building from scratch.
- 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
New Relic is in active rollout across Tesco's engineering teams. You will be a key driver of adoption, new capability delivery, and platform governance.
- 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
Runscope is already rolled out to teams for API monitoring. Your focus is on maintaining reliability, improving security, and ensuring SLOs are met.
- 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
A key growth area for the team is helping infrastructure teams adopt observability by deploying and managing the OpenTelemetry (OTel) Collector as the standard telemetry pipeline.
- 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
