What will you bring to the team.

Toshiba Global Commerce Solutions is seeking a Sr. Platform Performance Support Engineer that plays a key role in engineering performance, resilience, and observability across a three‑tier distributed architecture spanning edge devices, in‑store servers, and cloud services. This role uses AI‑enabled automation to validate and enforce production‑grade reliability, with the ultimate goal of delivering measurable system stability at retail scale. The position operates at the intersection of distributed systems architecture, performance engineering, reliability validation, and intelligent automation.

What will you be doing:

• Design and implement platform mechanisms that ensure transaction integrity and availability across POS
• terminals, store middleware, and cloud services.
• Define and validate failure‑mode strategies for intermittent connectivity, tier isolation, data replay, and
• synchronization conflicts.
• Engineer patterns that prevent cascading failures and support graceful degradation under real‑world load.
• Define latency budgets and performance envelopes across all tiers.
• Build systems that measure and validate throughput, concurrency limits, and resource saturation.
• Collaborate with development teams to eliminate bottlenecks before production.
• Develop AI‑enabled systems that automatically generate and execute performance and resilience validation.
• Integrate non‑functional quality gates into CI/CD workflows.
• Continuously evaluate timeout, retry, circuit breaker, and backoff strategies under stress.
• Architect structured telemetry across edge, store, and cloud tiers.
