Role summary

Seeking a Founding Platform Engineer to build and scale the data platform for Converge. This individual contributor role involves deep technical work on infrastructure and systems problems, focusing on building services that handle massive data volumes and real-time processing. Responsibilities include performance tuning, data ingestion, system design, and potentially developing a custom SQL dialect. The role requires strong coding skills, a deep understanding of databases (OLTP & OLAP), and experience with large-scale data-heavy systems. This is an in-person role in NYC, emphasizing hands-on implementation over high-level architecture.

We’re looking for a **founding engineer** to own and build out the **data platform** powering Converge.

Right now we are **just 3 product engineers** and already **operate systems most companies don’t touch until much later**. You’ll be the first engineer to fully own and scale the platform layer:

* Handling **$4 billion** in annual revenue
* Ingesting **20 TB** every month
* Processing **5 billion jobs** every month
* **6000 jobs / s** at peak
* Queries join, window, and aggregate up to **100M rows** (100GB) in **seconds**, fully **real-time**.

This is **not a typical SRE, systems, or backend engineering role**. You will:

* **Drive your own roadmap**
* Go super **deep** on the **hardest** infra and systems problems
* Work with product engineers to **ship product that scales** to the **world’s largest** consumer brands.

Some examples of what you’ll be working on:

* **Build out services** that can ingest up to a **trillion** **jobs / month**
* Stare at **esoteric Clickhouse CPU and memory flamegraphs**
* Figure out how to **materialize our attribution dataset** to scale to join, window, and aggregate **billions of rows** in realtime
* **Build a SQL dialect** for our customers (or agents) to directly query the data in Converge

### This role is NOT for you if

* You **prefer to architect systems over building** them. You will implement everything you design. **Expect to be coding, a lot**.
* You want to **own "big tech" style, multi-quarter** migrations. We work with daily and weekly timelines.
* You **prefer working remote over in-person**. We all love working from our NYC office.

### What we’re looking for

* **Very strong coding** skills (we mostly work with Python, you should be familiar with more performant languages)
* **Deep understanding of databases** (OLTP & OLAP) (we work with Postgres & Clickhouse)
* **Experience at scale** (you’ve seen first hand where things fall over in data-heavy systems)
* You’re **pragmatic** and **customer-minded**. The best solutions involve a deep understanding of what customers need and of what’s _not needed_.
