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.

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.

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.

• Design, build, and maintain the core platform services and infrastructure that power VibeIQ - search, file management, identity, authentication, work spaces, 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.

• 5+ years of experience in backend, platform, or infrastructure engineering
• Deep, hands-on experience with AWS - you should be comfortable across Lambda, API Gateway, DynamoDB, S3, Open Search, IAM, and related services
• Experience designing and maintaining scalable, distributed backend systems (Node.jsand Type Script preferred)
• Strong understanding of security and authentication patterns in cloud-native environments
• Experience with monitoring, observability, and operational tooling for production systems
• Demonstrated ability to own ambiguous technical problems, define requirements, and drive solutions independently
• Comfort working across a broad surface area - platform engineers at VibeIQ touch everything from core infrastructure and identity systems to search, file services, and AI tooling
• Strong debugging and problem-solving skills across distributed systems
• Clear, effective technical writing - design docs, runbooks, and documentation that others can act on without follow-up
• Excellent cross-functional communication skills - you can explain technical tradeoffs to engineers, product managers, and leadership alike
• Startup…
