Jobs at Factual

Hard problems. Diverse technology. Amazing culture.

Solve Hard Problems

Working at Factual means working together with fellow puzzle-addicts on projects that excite, deconstruct, explode, and reshape our thinking. We're here to solve real problems that take serious applied and theoretical skills because the data we deal with is noisy, contradictory, and there are petabytes of it.

Here are a few thought experiments to give you an idea of the types of problems that come with keeping up the world’s best place data...

Work with Diverse Technology

At Factual, we pride ourselves on applying the right tools to the right tasks. Consequently, we use a wide variety of technologies ranging from those that are well established to some that are new and cutting edge.

Web Stack

  • Node.js
  • Redis
  • MySQL
  • React
  • Rails


  • Mesos
  • Docker
  • Marathon
  • Chronos
  • AWS

Data Stack

  • Hadoop
  • Spark
  • HBase
  • Parquet
  • Parkour
  • Impala
  • Yarn
  • Solr
  • Lucene
  • PostgreSQL

Data Science & Machine Learning

  • Drake
  • Ensemble Methods
  • Neural Networks
  • Random Forests

Open Source Projects from Factual


Drake is a simple-to-use, extensible, text-based data workflow tool that organizes command execution around data and its dependencies.


Durable Queue

This library implements a disk-backed task queue, allowing for queues that can survive processes dying, and whose size is bounded by available disk rather than memory. It is a small, purely-Clojure implementation focused entirely on the in-process use case, meaning that it is both simpler and more easily embedded than network-aware queue implementations such as Kafka and ActiveMQ.



Clojure programmers can answer questions about coordinates, distances, and polygon intersections.



Riffle is a read-only key/value storage format, strongly influenced by the cdb and sorted-string table formats. Like cdb, it has a fixed memory cost per key (12 bytes per key), rather than having to keep the entire keyspace in memory. Like sorted-string tables, it allows for block compression of the values, and allows for files to be merged in linear time. Like both formats, a typical lookup requires a single disk read.



This library allows an ordered stream of entries to be uploaded to Amazon's S3 datastore.



Brought to you by Factual Engineer Spencer Tipping, nfu is a text data hub and transformation tool with a large set of composable functions and source/sink adapters.


Common Crawl

Brought to you by Factual Engineer Ahad Rana, Common Crawl builds and maintains an open repository of web crawl data that can be accessed and analyzed by anyone.

Our Mission

Our mission is to make data accessible to every developer, entrepreneur, business, or organization - anyone who needs data to build a better app, provide a better search result, make smarter software - anyone who needs data to make a better decision or help others make better decisions.

Our Values

We are constantly searching for unique ways to improve the health and happiness of our team. Our hope is that we become better people by working here.
