Sr. Full Stack Engineer (Backend)

VibeIQ Inc.•Boston, MA

21h•Hybrid

About The Position

At VibeIQ, we pioneer the future of digital collaboration with our innovative suite of apps built specifically for product teams. Our mission is helping companies that design, manufacture, or sell products work more effectively, enable a better work-life balance, and reduce their environmental impact. We're looking for a Sr. Full Stack Engineer to join the Core Apps team. Core Apps builds the products our customers use every day: the collaboration board, the planning grid, and the showcases they share with partners and buyers. We also own the services and shared libraries behind them, covering line planning, item search, assortments, documents, presentations and previews, projects, custom entities, and AI-assisted line and item generation. This is a true full stack team, and this role leans backend. You'll own API services across the domain, from the data model and service architecture through the AWS infrastructure they run on. You'll also work in the Angular apps that consume those services. This is a hybrid role based in Boston with 2 days per week in office.

Requirements

5+ years building and running production backend services, TypeScript and Node.js preferred.
Hands-on AWS depth across Lambda, API Gateway, DynamoDB, S3, IAM, and event-driven services such as SQS and SNS. You've operated what you built.
A track record of API design and data modeling in reliable, high-traffic systems.
Working proficiency in a modern frontend framework, Angular preferred or React.
Strong debugging skills in distributed systems. You can research a problem, weigh the options, and design a fix that spans the stack.
Clear technical writing: design docs, runbooks, and decisions others can act on without follow-up.
Proactive communication. You care about learning, growing, and helping others do the same.
Startup mentality: comfort with ownership, fast iteration, and wearing multiple hats

Nice To Haves

Domain experience in retail, apparel, or consumer products: line planning, assortments, merchandising, or PLM.
Experience shipping LLM-backed product features, including prompt design, evaluation, and cost and latency tradeoffs.
Familiarity with SaaS integrations such as PLM, DAM, PIM, or ERP systems.
Experience with real-time sync, WebSockets, or collaborative editing.
Depth in Angular, NgRx/RxJS, or browser performance work.
Experience with OpenSearch or Elasticsearch at scale.
Experience with automated testing and testable system design.

Responsibilities

Design, build, and maintain the backend services behind our core apps.
Run those services on AWS and stay accountable for their reliability, performance, observability, and cost.
Build AI-assisted generation features, such as generating lines and items from customer data, along with the services that support them.
Own features end to end, from technical design through deployment and monitoring, including the Angular work when the feature calls for it.
Model data for large customer catalogs and multi-tenant workloads, and keep it fast as those catalogs grow.
Work with product managers, designers, and other engineers to define what we build, and bring your own ideas to that conversation.
Diagnose and fix production issues across distributed systems.
Improve how we work: code quality, code review, continuous integration, and testing.
Mentor other engineers, lead design reviews, and raise the technical bar on the team.
Collaborate with teams across VibeIQ to improve our product, architecture, and engineering practices.
