Roles & Responsibilities

• Own the end-to-end technical architecture and engineering delivery for the POS platform, from discovery and solution definition through build, pilot, enterprise store rollout, and stabilization.
• Remain hands-on: create reference implementations, review critical code, diagnose complex defects, validate performance, and lead resolution of production incidents and edge cases.
• Translate business capabilities and nonfunctional requirements into scalable microservices, integration, data, security, deployment, and observability designs.
• Define architecture decisions, interface contracts, technical standards, guardrails, quality gates, and engineering practices; ensure traceability and compliance through delivery.
• Lead design reviews, technical spikes, proofs of concept, capacity planning, threat modeling, failure-mode analysis, and go-live readiness assessments.
• Partner with product, store operations, security, infrastructure, integration, QA, release, and support teams to manage dependencies, risks, and technical trade-offs.
• Present options and recommendations to senior stakeholders with clear rationale, business impact, delivery risk, and measurable success criteria. Mentor engineers, raise code and design quality, address capability gaps, and establish reusable patterns that improve delivery speed, reliability, and maintainability.
• Track and improve engineering outcomes such as defect leakage, service availability, response time, deployment quality, incident recovery, and rollout readiness.
