We built something a bit novel that is focused on composable integration testing in Clojure. We've used this for many years and found it quite useful for keeping a large testing codebase sane.

Amperity | Seattle / NY / Zoomverse | Remote | Full-time

Amperity is hiring a variety of technical roles: Engineering Manager, Applied Data Scientist (Lead), Senior Software Engineer.

Interesting problems: - Ingesting and cleaning massive amounts of data daily and blending it with real-time events - Automatically stitching data together across disparate systems by training machine-learning models to build a probabilistic knowledge graph - Taking research algorithms and productionizing them for high-scale usage - Allowing users to perform complex, real-time queries across an aggregated view of their data - Publishing query result data to a diverse set of systems for client usage.

Tech stack: - Clojure/ClojureScript - React/Reframe - Mesos/K8S - Spark - Kafka - SaltStack/Terraform - Riemann/InfluxDB/Grafana
