Position Summary
Five Below is seeking a Solutions Architect II to lead the design and implementation of our enterprise omnichannel initiatives, with a primary focus on Manhattan Active Omni (MAO) and the broader omnichannel order lifecycle. This role defines and drives end-to-end architecture for order capture, distributed order management (DOM), fulfillment orchestration, inventory visibility, and post-purchase experiences - ensuring all solutions are scalable, resilient, and aligned with our retail and customer-experience strategies.
You will serve as the bridge between business strategy and technical execution, translating complex omnichannel opportunities into actionable architectural blueprints that deliver measurable business value. This is a hands-on technical role: you will both design architectures and dive into configurations, integrations, and systems - partnering with teams across technology, merchandising, supply chain, stores, and e-commerce to bring production-ready omnichannel capabilities to life.
The role demands deep, application-level fluency that goes well beyond general OMS familiarity - owning integration design, tracing data flows end-to-end, and tuning system configurations hand-in-hand with engineering, product, and operations partners.
This role mandates active use of AI productivity tools - including Cursor, Claude, Glean, and equivalent platforms - to accelerate delivery and model best practices for the broader engineering organization.
Key Responsibilities
1. Omnichannel Architecture & Strategy
- Define and own the enterprise omnichannel architecture, aligning with Five Below's business priorities and multi-year technology roadmap.
- Develop reference architectures, integration patterns, and design standards for order management, fulfillment orchestration, and inventory availability.
- Translate retail business problems - spanning stores, e-commerce, digital, supply chain, and customer experience - into scalable omnichannel solution blueprints.
- Partner with business, product, and engineering leaders to identify and prioritize high-impact omnichannel capabilities such as BOPIS, BORIS, Same-day fulfillment, Ship-from-store, and endless aisle.
- Champion API-first, event-driven, and microservices design principles as the default approach before evaluating packaged commercial alternatives.
2. Manhattan Active Omni Design & Implementation
- Lead the architecture, configuration, and implementation of Manhattan Active Omni - including Order Management, Store Fulfillment, and Inventory & Order Visibility - across all fulfillment channels.
- Design order routing, sourcing rules, fulfillment workflows, and exception management within Manhattan Active Omni to optimize cost-to-serve and customer promise accuracy.
- Establish configuration and extension standards for Manhattan Active Omni, including orchestration process flows, service mappings, fulfillment strategies, and business rule frameworks.
- Define upgrade, patch, and release management standards for Manhattan Active Omni environments to ensure production stability and continuous improvement.
- Evaluate and advise on adjacent platform expansions - including commerce, merchandising, and warehouse management systems - and their integration with the OMS.
3. System Integration & API Design
- Architect end-to-end integration patterns connecting OMS to all upstream and downstream retail systems: e-commerce platforms, POS, WMS, ERP, CRM, carrier/logistics providers, and customer-facing touchpoints.
- Define API standards (REST, GraphQL, event-driven via Kafka or equivalent) for order, inventory, fulfillment, and return data flows.
- Design real-time inventory visibility solutions - bridging store, DC, and in-transit inventory - to power accurate available-to-promise (ATP) and omnichannel order routing decisions.
- Lead integration design for carrier management, last-mile delivery, and third-party logistics (3PL) partners.
- Establish integration governance including API versioning, schema standards, error handling, retry logic, and dead-letter management.
4. Fulfillment & Store Operations Architecture
- Architect fulfillment capabilities - BOPIS, curbside pickup, ship-from-store, ship-to-store, and endless aisle - on Manhattan Active Omni Store Fulfillment, ensuring store associate experience and operational feasibility are first-class design inputs.
- Design the distributed order management (DOM) logic to dynamically route orders across DCs, stores, and drop-ship vendors based on inventory proximity, capacity, and cost rules.
- Define returns and reverse logistics architectures - including in-store returns of online orders, carrier returns, and vendor returns - aligned to customer experience and operational efficiency goals.
- Partner with Store Technology and Operations to ensure Manhattan Active Omni Store Fulfillment workflows - pick, pack, stage, customer handoff, and in-store returns - integrate seamlessly with POS (Aptos or equivalent) and store associate tooling.
- Drive fraud management and payment capture architecture within the order lifecycle, partnering with Finance and Risk teams.
5. Performance, Scalability & Observability
- Define non-functional requirements (NFRs) for all OMS and omnichannel systems: throughput, latency SLOs, availability targets, and disaster recovery posture.
- Establish an observability framework for omnichannel systems covering real-time monitoring, SLO/SLA alerting, order pipeline health, and integration fault detection.
- Design load testing, capacity planning, and peak readiness (holiday, back-to-school) strategies for OMS and fulfillment infrastructure.
- Partner with Platform Engineering to embed observability, logging, and distributed tracing as first-class requirements in every omnichannel system.
- Establish runbooks and automated alerting for critical failure scenarios - including order routing failures, inventory sync outages, and fulfillment SLA breaches.
6. Data Architecture & Reporting
- Define the omnichannel data model - covering orders, shipments, returns, inventory events, and customer interactions - to support real-time operational reporting and strategic analytics.
- Architect data pipelines that feed omnichannel operational metrics into enterprise data platforms (Snowflake, Databricks, or equivalent) for reporting and advanced analytics.
- Partner with Data Engineering to ensure order and fulfillment data is available for customer-facing use cases - including order status, tracking, and self-service returns - and internal KPI dashboards.
- Define data governance standards for omnichannel datasets including ownership, retention, access controls, and PII handling.
7. Technology Evaluation, Governance & Vendor Management
- Lead build-vs-buy-vs-configure decisions for omnichannel capabilities, weighing Manhattan Active Omni extensibility against SaaS alternatives and custom microservices.
- Evaluate and recommend platform investments - including e-commerce platforms (Salesforce Commerce Cloud, commercetools, or equivalent), OMS add-ons, and carrier/logistics APIs.
- Define vendor selection criteria and lead RFP/POC processes for omnichannel technology investments.
- Establish technology governance: architecture review boards (ARBs), decision records (ADRs), and standards documentation for the omnichannel platform.
- Partner with Security, Legal, and Enterprise Architecture to align omnichannel solutions with data privacy, PCI compliance, and corporate risk standards.
8. Technical Leadership & Delivery
- Work closely with Software Engineers, Integration Engineers, QA, and platform teams to ensure architectures are production-ready and executable within agile delivery cycles.
- Provide hands-on guidance during implementation phases - including reference configurations, API contracts, data schemas, and infrastructure patterns.
- Lead architectural reviews and design sessions, ensuring solutions meet performance, scalability, security, cost, and maintainability requirements before build begins.
- Mentor and upskill engineering teams on omnichannel patterns, Manhattan Active Omni best practices, and integration design principles.
- Align delivery roadmaps with business program timelines, proactively surfacing technical risks and trade-off decisions to product and program leadership.
