Validate transaction performance under varying conditions, including peak checkout periods, offline mode, and degraded network scenarios.

• Test cloud‑connected POS services, including pricing, promotions, tax calculation, loyalty, and payment gateway integrations.
• Lead migration testing for POS software upgrades, device replacements, OS updates, and backend service transitions.

Leverage AI to build automation scripts for repeatable non‑functional testing across CI/CD pipelines supporting rapid retail deployments. Analysis & Reporting

• Analyze system behavior under high‑volume transaction loads and store‑level stress conditions.
• Provide detailed reports on POS performance metrics, reliability KPIs, and hardware‑specific bottlenecks.
• Collaborate with engineering, store operations, and infrastructure teams to diagnose performance issues and recommend improvements.

Collaboration & Technical Leadership Partner with store operations teams to replicate real‑world store scenarios, including multi‑lane checkout, network failover, and device interoperability.

• Work with cloud and DevOps teams to simulate production‑like environments for POS‑backend services.

Advocate for non‑functional quality standards across POS and store‑technology initiatives.

• Mentor junior engineers on performance engineering, hardware testing, and reliability best practices.
