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.
