Photon Group is hiring a Site Reliability Engineer to ensure the availability, reliability, scalability, and performance of our most critical, customer-facing eCommerce microservices. You will apply Google-inspired SRE principles to balance feature velocity and system reliability using Service Level Objectives, Service Level Indicators, and error budgets.

What You'll Do

Define, implement, and own SLIs, SLOs, and error budgets for critical microservices in collaboration with product and engineering teams.
Use error budgets to influence release decisions, prioritize reliability work, and manage operational risk.
Design and maintain observability platforms including metrics, logs, traces, and real-time telemetry.
Track, manage, and reduce operational toil by converting repetitive work into actionable Jira stories and epics.
Design, implement, and validate resiliency mechanisms such as graceful degradation, redundancy, automated failover, and disaster recovery.
Lead incident response, act as an escalation point for high-severity incidents, and drive blameless postmortems.
Capture incident action items and reliability improvements in Jira, ensuring closure, accountability, and continuous improvement.
Partner with scrum teams to improve reliability through release readiness reviews, production change validation, and testing strategies.
Perform deep root cause analysis, debugging, and performance tuning across distributed systems.
Promote shift-left reliability by embedding operability, monitoring, and failure testing early in the software development lifecycle.
Drive continuous improvement through automation, self-healing systems, chaos engineering, and capacity planning.
Maintain runbooks, playbooks, and knowledge repositories, linking documentation to Jira tasks to reduce Mean Time to Resolution.
Provide technical leadership and mentoring to junior SREs and engineers.
Collaborate with global, distributed teams, leveraging Jira for transparent planning, dependency tracking, and execution.

What We're Looking For

4+ years of experience in SRE, software engineering, or production operations supporting large-scale eCommerce platforms.
Hands-on experience with Java/J2EE-based distributed systems.
Proven ability to design and operate systems using SLO-driven reliability models.
Experience defining and measuring SLIs (availability, latency, error rates, throughput, saturation).
Good understanding with NoSQL technologies and RDBMS, including the ability to write queries.
Experience deploying and operating services on cloud platforms (AWS, Azure, or Google Cloud).
Expertise with observability, APM, and caching tools (Dynatrace, Splunk, ELK, Akamai, QuantumMetric/Tealeaf, etc.).
Strong experience using Jira for backlog management, incident follow-ups, toil reduction tracking, and cross-team coordination.
Ability to independently own services and drive reliability initiatives end-to-end.
Strong communication skills and ability to influence engineering and product teams.
Experience being on an On-Call rotation and handling critical or high-severity incidents.

Nice to Have

React experience is a plus.
Experience building and operating microservices architectures using Spring Boot, Groovy, React, or similar.
Strong understanding of CI/CD pipelines, release automation, and progressive delivery.
Experience with eCommerce domains such as Catalog, Customer Data, and Order Management.
Familiarity with search platforms (Endeca, Solr, Lucene, Elasticsearch).
Proficiency in scripting and automation (Python, Bash, Ruby, Perl, PowerShell).
Experience with ITSM tools integrated with Jira workflows.
Exposure to capacity planning, load testing, and chaos engineering.
