Senior Backend Engineer (Remote)

What You Will Do

We currently have a marketplace that connects buyers and sellers of AdTech data, and we are building on this success to make it possible to transact any other kind of data.

Here are the kinds of projects you will likely work on:

  • Add capabilities to our query execution and data classification engines to make it possible to answer any buyer query.
  • Iterate on our forecasting system so that buyers get faster, more accurate insights into the volume and quality of data they are purchasing.
  • Build out additional connectors to make it effortless to get data into and out of our marketplace.
  • Design a framework for metering resource usage by partner (e.g. storage, server hours, API calls) and integrate it into billing.
  • Improve query planning, optimization, and batching to make sure our transaction jobs are running efficiently.
  • Help buyers and sellers build data workflows on the platform. E.g. enabling buyers to use the output of one of their purchases as an input filter to another.
  • Automate table maintenance tasks like file compaction, data retention, choosing partitioning and sort strategies based on statistics gathered about a dataset and historical query patterns, etc.
  • Architect service interfaces and composable subsystems as we scale the team and decompose our monolith.
  • Improve the monitoring and reliability of our systems with the ever-increasing amount of data being handled: currently we're ingesting > 10 TB of data from sellers every day.
  • Extract abstractions, modularize the code, and improve tests.

Technical Stack

In a nutshell, our technical stack looks like:

  • Frontend: Vuejs, Sass, Pug, and Functional JavaScript
  • Backend: scala, AWS, spark, Iceberg, cats, cats-effect, http4s, and doobie

The Ideal Candidate

We are not looking for a 100% fit on all the technology buzzwords, but we are looking for someone with strong personal and technical skills who is eager to pick up new technologies as necessary.

The ideal candidate should:

  • Have experience in a typed functional language such as Scala, F#, or Haskell, or significant experience in their non-functional equivalents (Java, C#) with an interest in Scala and Functional Programming.
  • Have experience working with non-trivial quantities of data. Prior experience with Spark would be ideal, but experience with any distributed query engine (Trino, Dremio, etc.) would also be helpful.
  • Have experience operating in a cloud environment like Amazon Web Services, Google Compute Engine, or similar.
  • Be able to work across all aspects of backend systems, from application code to SQL to systems administration.
  • Not be afraid of contributing to the entire stack (from the UI to Devops) when the need arises.
  • Have the ability to lead the creation of architectural and design documents, collect requirements as well as feedback from the development and product teams and evalute new technologies as needed.
  • Drive success in a flat organization with minimal process, interfacing with technical and non-technical team members as necessary.
  • Communicate potential technical issues to relevant teams and adapt to changing requirements.
  • Be mindful of the compromises that need to be done to be reactive on the business side while keeping the systems manageable in the long run.
  • Live/work within +/- 3 hours of EST

The Team

We are a small, early stage, remote-first team looking for great developers who want to jump in and take major systems and user-facing features from design to launch.
