This role builds and evolves the engineering systems that protect reliability across the software lifecycle. The engineer in this position designs automated testing infrastructure, release validation safeguards, and production observability systems that ensure software can be delivered safely and operated reliably at scale.

Engineers in this role strengthen delivery quality by building durable validation systems, improving production diagnostics, and enabling teams to release software with confidence while maintaining operational continuity for active stores.

RESPONSIBILITIESDesign andoperatethe automated testing platform used across engineering teams, including unit, integration, and end-to-end testing infrastructureDefine testing strategies that protect critical retail and transactional workflows through reliable regression coverageBuild realistic test environments and scenarios that simulate real store operations and transaction behaviorImplement automated release validation within CI/CD pipelines to prevent unstable code from reaching productionDesign deployment safeguards including release checks, rollback mechanisms, and validation gatesDefine and implement observability standards including structured logging, metrics, and distributed tracingBuild monitoring dashboards and alerting systems that provide clear operational visibility into production systemsImprove production diagnostics so engineers can quicklyidentify, debug, and resolve system failuresDrive reliability practices across engineering through architecture guidance, design reviews, and tooling improvementsEnsure new services and features meet reliability, testability, and observability standards before reaching production

VALUABLE

EXPERIENCEExperience supporting transactional platforms involving payments, inventory, or financial recordsExperience operating observability platforms for monitoring applications or cloud infrastructureExperience working with distributed or service-orientedarchitectureExperience supporting legacy systems during modernization effortsExperience working in retail or multi-location franchise platforms where operational continuity is criticalHOW WE OPERATEEngineers at Winmark are accountable for technical direction, implementation quality, operational stability, and measurable business outcomes.

Wedesign fordurability and operational continuity.

We prioritize data integrity and reliability over short-term speed.

We modernize legacy systems without destabilizing store operations.

We own production health: performance, uptime, incident response, and correction.

We make deliberate tradeoffs grounded in business impact.

WHY THIS ROLE

MATTERSOur franchisees are local small business owners who rely on our systems to manage inventory, serve customers, and run profitable stores.

These stores keep goods in circulation within their communities. Families can buy and sell clothing and equipment locally, making everyday items more affordable while reducing waste and extending the life of products that would otherwise be discarded.

The reliability of our platform directly affects the entrepreneurs running these businesses and the communities they serve.
