Senior Software Engineer (Platform)

ABOUT US VibeIQ is transforming the way brands bring products to market. We are the first and only Assortment Lifecycle Platform built for today’s retail, fashion, footwear, and apparel brands. VibeIQ is where merchandising, design, and B2B sales teams unite to create, evolve and launch high-performing assortments–with speed, clarity, and confidence. As a fast-growing Series A company, we’re looking for product-obsessed, proactive thinkers who thrive in ambiguity and want to shape the future of our Product and Engineering function. POSITION SUMMARY We're looking for a Senior Software Engineer to join our Platform team. This role sits at the center of our engineering ecosystem - you'll work across the full development lifecycle, building and maintaining the shared infrastructure, core services, and tooling that our product teams depend on every day. The Platform team at VibeIQ owns three critical pillars of the product. Engineering Foundation - the infrastructure, security and authentication, monitoring, identity systems, service patterns, and SDK stewardship that everything else is built on. Platform Services - the core services that power the product, including search, file management, change history, user and group management, workspaces, and the type and policy system. AI Infrastructure - the patterns, infrastructure, and deployment guidelines for MCP and agent systems, including token management and throttling. You'll operate with significant autonomy, own ambiguous technical problems end-to-end, and make decisions that affect the trajectory of the entire engineering organization. This is not a role where you execute against a narrowly scoped backlog. You'll identify what matters, define how to solve it, and drive the work from design through production - often across team boundaries. ESSENTIAL FUNCTIONS Design, build, and maintain the core platform services and infrastructure that power VibeIQ - search, file management, identity, authentication, workspaces, and more. Own major components and multi-month initiatives end-to-end - from technical design through deployment and monitoring. Build and maintain AWS infrastructure, ensuring reliability, scalability, and cost efficiency across the platform. Define and enforce service patterns, best practices, and engineering standards that product teams build on. Own and evolve security and authentication systems, monitoring tools, and observability across the stack. Steward platform SDKs - ensuring they are well-designed, documented, and maintainable. Design and build AI infrastructure - including MCP patterns, agent systems, and token management and throttling. Partner across teams to identify platform needs, reduce friction, and close gaps in shared capabilities. Contribute to technical strategy, including evaluating new technologies and making build-vs-buy recommendations. Debug and resolve critical production issues across distributed systems. Mentor junior engineers, lead design reviews, and raise the technical bar for the team.
