About Reflex

Reflex is the operating system for building mission-critical enterprise applications.

Today’s enterprise stack is fragmented. Shipping an app requires stitching together multiple tools and coordinating across multiple roles. Reflex replaces that complexity with a single, unified platform to build, deploy, and manage production applications end-to-end.

We empower teams to own the entire lifecycle of their apps — from idea to production — without needing specialized infrastructure, DevOps, or platform teams. We do this by providing solid, reusable abstra at both the framework and infrastructure layers. Because we own the underlying open-source framework and the platform it runs on, we can manage the full lifecycle of the application seamlessly.

With Reflex, teams securely connect to company data, use AI to build standardized applications on top of our open-source framework, and deploy with a single click to share across their organization.

We’re replacing the fragmented enterprise stack — and the organizational bottlenecks that come with it.

Why join Reflex now?

• Growth: Reflex has powered over 1 million applications, earned 28,000+ GitHub stars, and is used by 30% of Fortune 500 companies for internal tools and data‑driven applications.
• Team: Work with people who are genuinely passionate about improving the web. Our founding team consists of open source maintainers, top‑ranked competitive programmers/IOI medalists, and founding team members from dev‑tool unicorns.
• Future: We are growing extremely quickly and have just raised another round of funding.

About the interview

• Once you've submitted your application, the team will review your submission and may reach out for an intro call.
• After the intro call, there will be a technical take‑home test and then an on‑site with 2–3 technical interviews, each around 45 minutes.
• Once the interviews are over, the team will meet to discuss several roles and candidates, and may be asked one or two follow‑up questions over email, a quick call, or go directly to make an offer.
