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. ESSENTIAL FUNCTIONS * 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. ## Related Videos - [How to Create New RxJS Operators](https://www.wearedevelopers.com/videos/683-how-to-create-new-rxjs-operators) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Build and Deploy a Fullstack App with Open Source Tooling](https://www.wearedevelopers.com/videos/775-build-and-deploy-a-fullstack-app-with-open-source-tooling) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Lessons for Vibe Coders and Developers](https://www.wearedevelopers.com/magazine/614-lessons-for-vibe-coders-and-developers)
