15+ years (including 5+ years in observability/SRE architecture)
Employment Type:
Full-time
Role Overview
We are looking for a highly experienced
Technical Architect

design, strategy, and implementation
of
Observability and SRE frameworks
for enterprise-scale, microservices-based applications.
The ideal candidate will bring deep technical knowledge of both
Splunk Observability Stack
and
Open Source tools
(like OpenTelemetry, Prometheus, Grafana, Jaeger), and be capable of defining and executing architecture strategies for complex distributed systems.
This role requires hands-on ability to
create architecture blueprints
, lead technical teams, and work directly with stakeholders and platform owners to embed observability and reliability practices across the SDLC.
Key Responsibilities
Design and deliver
end-to-end observability architecture
(Metrics, Logs, Traces, Events) for cloud-native and hybrid environments.
Create
technical architecture diagrams
, data flow maps, and integration blueprints using tools like Lucidchart, Draw.io, or Visio.
Lead the definition of
SLIs, SLOs, and Error Budgets
aligned with business KPIs and DORA metrics.
Architect telemetry pipelines using OpenTelemetry Collector and Splunk Observability Cloud (SignalFx, APM, RUM, Log Observer).
Define tool adoption strategy and integration roadmap for OSS tools (Prometheus, Loki, Grafana, Jaeger) and Splunk-based stacks.
Reliability Engineering Enablement
Lead adoption of SRE principles including incident management frameworks, resiliency testing, and runbook automation.
Collaborate with DevOps to integrate observability into CI/CD pipelines (e.g., Jenkins, ArgoCD, GitHub Actions).
Define health checks, golden signals, and SPoG (Single Pane of Glass) dashboards.
Exposure to
AIOps
, ML-based anomaly detection, or business observability.
Stakeholder Management & Governance
Serve as a technical liaison between client leadership, SREs, developers, and infrastructure teams.
Run workshops, assessments, and evangelize observability-first culture across teams.
Provide guidance on data retention, access control, cost optimization, and compliance (especially with Splunk ingestion policies).
Performance & Optimization
Continuously monitor and fine-tune observability data flows to prevent alert fatigue and ensure actionability.
Implement root cause analysis practices using telemetry correlation across metrics, logs, and traces.
Lead efforts to build self-healing systems using automated playbooks and AIOps integrations (where applicable).
Required Skills & Qualifications
15+ years in IT, with
5 years in Observability/SRE architecture roles
Proven experience designing architecture for
microservices, containers (Docker, Kubernetes), and distributed systems

(AWS, Azure, GCP) and container orchestration (K8s/OpenShift)
Familiarity with
SRE and DevOps best practices
(error budgets, release engineering, chaos testing)
Nice to Have
Splunk certifications:
Core Consultant, Observability Specialist, Admin
Knowledge of ITIL and modern incident management frameworks (PagerDuty, OpsGenie)
Experience in
banking or regulated enterprise environments
Soft Skills
Strong leadership and
cross-functional collaboration
Ability to work in ambiguous, fast-paced environments
