Growth Engineer at Reflex | Y Combinator

You will own Reflex's go-to-market motion end-to-end, strategy through execution. We have strong product-market signals (1M+ apps built, 28k+ GitHub stars, Fortune 500 adoption) but no formalized GTM engine. We need someone who has built this before, taken an early-stage startup from unstructured inbound and founder-led sales to a repeatable, scalable pipeline, and can bring that playbook to Reflex.

You will:

- Engineer Systems to Assist with GTM and Growth

- Define and execute Reflex's GTM strategy: segmentation, positioning, channel mix, and pipeline architecture from the ground up

- Build the top-of-funnel engine, turning open-source adoption, product usage signals, and community engagement into qualified pipeline

- Stand up the systems and processes to support the motion (CRM, enrichment, outbound, lead scoring, routing) and decide what to build vs buy

- Partner directly with founders to translate product and community momentum into revenue

- Own the metrics: define what we measure, build the reporting, and drive weekly/quarterly forecasting

Qualifications

- You have experience in Software engineering, Machine Learning, Data Science, or some form of coding.

- You have some experience or heavy interested GTM motion at a startup.

- You've personally owned top-of-funnel strategy and pipeline creation, not just managed a team doing it

- Comfortable operating across strategy and execution. You can set the plan on Monday and get your hands dirty in HubSpot on Tuesday.

- Experience selling to or building GTM for a developer-facing or open-source product is a strong plus

- Technical fluency. You don't need to write production code, but you should be comfortable with data, product signals, and working directly with engineers.

- Bonus: experience with PLG motions, community-led growth, or open-source go-to-market

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 abstractions 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.
