Overview

• We're seeking an experienced Lead Engineer to design, build, and deliver core Retail Store systems that power retail client in-store and omnichannel experiences.
• This role will be hands-on and technical, owning the design and delivery of store-facing applications including POS, OMNI order fulfillment by stores, and inventory receiving.
• International store expansion will be a key responsibility, alongside ongoing enhancements and reliability of domestic and global store systems.
• Work closely with Product, Retail Operations, ERP, and external partners to deliver scalable, reliable, and pragmatic solutions for real-world store environments.
• Requires deep technical expertise, strong system design skills, and ownership mindset for store-critical platforms.

Responsibilities

• Lead the technical design and implementation of store systems including POS, OMNI fulfillment (ship-from-store, BOPIS, cancellations, returns), and inventory receiving.
• Act as a hands-on technical lead, setting architecture, coding standards, and best practices across the team.
• Translate business and operational requirements into scalable, resilient, and maintainable technical solutions.
• Contribute directly to development using Java, Python, NodeJS, and React across backend and frontend systems.
• Design and build integrations with Shopify, ERP, OMS, loyalty platforms, and third-party vendors.
• Support international store expansion by deep diving into localization, regional compliance, taxation, and operational requirements for new countries.
• Ensure systems work effectively in physical retail environments, including POS hardware, peripherals, and unreliable network conditions.
• Collaborate closely with store managers and store teams to understand operational pain points and deliver pragmatic, easy-to-adopt solutions.
• Partner with Retail Operations and Product on rollout planning, training support, and adoption of new store-facing features.
• Design and operate event-driven and distributed systems using Kafka, ensuring idempotency, retries, and eventual consistency.
• Own service reliability for store systems by defining SLOs, improving error rates, and reducing MTTR.
• Build and maintain monitoring, alerting, and observability using tools such as Splunk and New Relic.
• Participate in on-call rotations, incident response, root-cause analysis, and post-incident improvements.
• Plan and execute for peak retail events (promotions, holidays, store launches) and support change discipline during critical windows.
• Drive best practices for testing, CI/CD, release management, and infrastructure-as-code.
• Ensure data accuracy, auditability, and reconciliation across inventory, order, and financial systems.
• Maintain strong security, access controls, and compliance standards for systems used in physically accessible store environments.
• Mentor junior engineers through technical guidance, code reviews, and design discussions.

Qualifications

• 7+ years of software engineering experience, with experience leading technical design and delivery for complex systems.
• Strong domain experience in Retail systems, store operations, and omnichannel commerce.
• Experience delivering store-facing systems such as POS, inventory receiving, and order fulfillment.
• Proficiency in Java, Python, and NodeJS; experience building backend services using Spring.
• Experience with frontend development using React.
• Hands-on experience integrating with Shopify and other retail platforms.
• Strong experience with relational and NoSQL databases including Oracle DB, MySQL, and DynamoDB.
• Experience designing and operating event-driven architectures using Kafka.
• Strong understanding of distributed systems concepts including retries, idempotency, eventual consistency, and transactional patterns.
• Experience with monitoring, logging, and alerting using tools such as Splunk and New Relic.
• Experience owning production reliability, incident response, and operational metrics.
• Proficiency with build and configuration tools such as Maven, Ant, and YAML.
• Experience with source control and collaboration using GitHub.
• Hands-on experience with containerization and orchestration using Docker and Kubernetes.
• Experience deploying and operating systems in AWS, including SAM and Terraform.
• Understanding of payment processing, settlement, taxation, and country-specific compliance considerations.
• Experience with omnichannel retail workflows including store fulfillment, ship-from-store, BOPIS, split shipments, cancellations, and returns.
• Strong ownership mindset with accountability for technical quality and business outcomes.
• Data-driven problem solver with pragmatic engineering judgment.
• Excellent cross-functional collaboration and communication skills.
• Comfortable operating in fast-paced, imperfect retail environments where store impact is critical.
