Position Summary...

What you'll do...
We are seeking a seasoned Distinguished, Software Engineer - Site Engineering Architect to lead the technical architecture and cross-functional delivery for our eCommerce site platforms. In this role you will own the architecture, operational model, and engineering standards that enable highly available, secure, performant, and extensible eCommerce experiences. You will partner closely with engineering, product, UX, operations and business stakeholders to define technical strategy, drive execution for large-scale initiatives (including next-generation eCommerce platform work), and continuously improve how we design, deliver and operate solutions.

This role combines deep hands-on architectural leadership with program-level influence: you will design and validate solutions, unblock engineering teams, and lead improvements to the processes and observability that govern site reliability, performance, and compliance.

What you'll do:

• Lead architecture and technical strategy for core eCommerce site platforms (catalog, search, checkout, cart, personalization, promotions, storefront, content delivery), ensuring scalability, availability, security and extensibility.

• Drive execution for some of the organization's largest eCommerce initiatives - own architecture decisions, tradeoffs, success criteria and delivery risks across multiple teams and stakeholders.

• Create and sustain strong, practical collaboration between engineering, product management, UX/design, SRE and business partners so that architecture and delivery are tightly aligned with product goals and customer experience.

• Define and evangelize target state architectures (microservices, event-driven/data-streaming, edge/ CDN strategies, serverless/K8s, API and data contracts) and migration approaches from legacy systems.

• Establish and enforce engineering standards and best practices (API design, CI/CD, automated testing, infrastructure as code, secure coding, data privacy/PCI compliance).

• Shape and improve program delivery processes: roadmaps, planning cadences, risk frameworks, release gating, change control and cross-team dependency management to increase predictability and throughput.

• Design and implement observability, monitoring and alerting patterns (metrics, tracing, logs, synthetic monitoring, SLIs/SLOs) to reliably measure site health and customer impact; create runbooks and operational playbooks.

• Partner with SRE/ops to lead capacity planning, performance tuning, cost optimization and incident response improvements for site reliability and customer experience.

• Mentor and coach technical leads and engineers on system design, performance engineering, and trade-off analysis.

• Evaluate new technologies and third-party suppliers (search providers, payment gateways, CDNs, personalization engines) and drive technical due diligence and proof-of-concepts.

• Ensure engineering work complies with regulatory/security standards (PCI-DSS, GDPR, internal security policies) and auditability requirements.

• Communicate architecture and program status clearly to senior leadership and influence roadmap and investment decisions.
