Job Description: L2 Application Support Engineer
Position Count: 3 Roles
Location: Dallas, TX (Hybrid 3 Days)
Visa: not opt (H1B, H4 Ead, USC, GC and TN)
Role Overview
We are seeking experienced L2 Application Support Engineers to support business-critical production applications in a 24x7 operational environment. This is a hands-on L2 support role with strong emphasis on incident management, deep troubleshooting, observability, SQL, and cloud-based applications.
While the role has exposure to SRE/DevOps concepts, it is not a pure SRE or DevOps engineering position. The primary responsibility is application support, issue diagnosis, and operational stability.
Key Responsibilities
· Provide L2 production application support for mission-critical systems, ensuring high availability and rapid incident resolution.
· Own incident, problem, change, and BCP management activities in line with ITIL processes, including root cause analysis and post-incident reporting.
· Troubleshoot application issues using logs, metrics, dashboards, alerts, and SQL queries.
· Actively monitor production environments, proactively identifying performance, stability, and availability issues.
· Use Splunk extensively to analyze logs, create dashboards, configure alerts, and investigate production incidents.
· Interpret system and application metrics using Grafana, identifying trends, anomalies, and performance bottlenecks.
· Write and optimize medium-complex SQL queries to support troubleshooting, identify slow queries, and assist with performance tuning.
· Support applications hosted on cloud platforms (AWS, Azure, or GCP), including troubleshooting cloud-native components and services.
· Collaborate closely with development, SRE, platform, and infrastructure teams to resolve issues and improve operational reliability.
· Participate in on-call rotations and support activities aligned with business-critical production environments.
