At Rollstack, we are revolutionizing the way businesses share and communicate data and insights. Organizations worldwide rely on slide decks and documents to make informed decisions, whether for leadership, clients, or partners. Yet, preparing these materials often consumes countless hours. Rollstack fully automates that.

We help some of the world's leading organizations—from mid-sized to public companies like SoFi, Zillow and Whirlpool—in automating their slide decks and documents. Headquartered in New York, we offer a remote-friendly workplace and are backed by Insight Partners and Y Combinator, the most successful startup incubator in the world that produced the likes of Airbnb, Twitch, Instacart, Dropbox, Reddit, Doordash, Stripe, Coinbase, etc.

Our team operates with speed and focus to deliver outsized impacts for our customers. We approach every challenge with first principles, never assuming things have to be done a certain way. We are a diverse team that believes intelligence and kindness go hand in hand, welcoming individuals from all backgrounds. Our persistence and rapid execution define us as a category leader and a future generational company.

As a Software Engineer, you will
  • Build and maintain PowerPoint, Word, and Excel add-ins using .NET and C#.
  • Develop robust integrations with Microsoft Office APIs (VSTO, Office.js, or COM) to automate document creation and updates.
  • Ship high-impact features like auto-generated slides, AI-powered insights, and real-time data sync into Office documents.
  • Collaborate with highly technical engineers who care about building great software
Who Should Apply

  • 2-6 years of professional software engineering experience.
  • At least 1 year working with .NET (C#), especially building add-ins or integrations with Microsoft Office.

  • If you don’t want to talk to customers or iterate on feedback.
Why Join Us
