Top Tech Jobs & Startup Jobs

Build and maintain E2E automated tests using Playwright and JavaScript, expand coverage of critical B2B procurement flows, investigate failures and flakiness, log reproducible defects, collaborate with developers, and maintain CI/CD test pipelines while participating in test planning and QA process improvements.

Design and implement multi-tier offline-first synchronization for a global QSR POS: CRDT-based conflict resolution, event sourcing/CQRS/saga patterns, real-time pub/sub or WebSockets, and PostgreSQL-backed cloud data modeling and reconciliation with local and edge stores.

Design, build, and maintain backend integrations connecting a public-safety platform to third-party systems (911 centers, state databases). Develop Java/Spring Boot services, REST/SOAP/GraphQL integrations, write tests, debug production issues, document solutions, and collaborate on cloud-based, secure, scalable integration workflows.

Design and implement offline-first, multi-tier data synchronization for a global POS platform using CRDT-based frameworks (Automerge/Ditto). Apply event sourcing, CQRS, saga patterns, and pub/sub/WebSockets for real-time state. Model PostgreSQL cloud data and reconcile with local and edge stores.

Design, build, and maintain backend integrations connecting a public safety platform to third-party systems (911 centers, state DBs, external agencies). Develop Java/Spring Boot services, REST/SOAP/GraphQL integrations, write tests, debug production issues, improve reliability, and document systems while collaborating across teams.

Design, build, and maintain backend integrations connecting a public-safety platform to third-party systems using Java and Spring Boot. Develop REST, SOAP, and GraphQL integrations, improve RMS/CAD/Booking pipelines, write tests, debug production issues, document solutions, and collaborate across teams to deliver scalable, secure cloud-based integration workflows.

Backend-focused engineer building and scaling secure integrations between a public safety platform and third-party systems (911, state databases, agency systems). Design and implement Java/Spring Boot workflows, REST/SOAP/GraphQL integrations, write tests, debug production issues, and contribute to documentation and CI/CD to improve reliability.

Design and implement offline-first multi-tier data synchronization for a global QSR POS: CRDT-based conflict resolution, event sourcing, CQRS, sagas, real-time pub/sub, and PostgreSQL cloud modeling and reconciliation across device, edge, and cloud.

Design and implement multi-tier, offline-first synchronization for a global QSR POS: CRDT-based conflict resolution, event sourcing/CQRS/saga patterns, real-time pub/sub or WebSockets, and PostgreSQL-backed reconciliation between device, edge, and cloud.

Owner of offline-first data synchronization for a global QSR POS: design multi-tier sync across device, edge, and cloud; implement CRDT-based conflict resolution (Automerge/Ditto), vector clocks and merge policies; apply event sourcing, CQRS, and saga patterns across order/payment flows; use real-time pub/sub/WebSockets; model and reconcile PostgreSQL cloud data with local and edge stores.
