Software Engineer (Scala)

Job description


What we are doing


Kaizo aims to actively guide employees towards achieving their goals and making an impact at their companies.

We are building a performance development platform for customer support teams that leverages gamification and AI to improve operational efficiency, elevate teams' performance and retention with actionable goals. We are a product-led, fast-growing SaaS company with a diverse team and a globally active customer base.


  • Kaizo is leveraging gamification and machine learning to make the daily work experience for customer support agents more engaging, fun and productive.
  • We run a microservice-based stream processing platform which processes 200+ million events every day using Akka Streams and Kafka.
  • Those services are deployed to Kubernetes on Google Cloud and feed data into Elasticsearch and Mongodb.
  • Our systems are designed to be reactive, e.g. responsive, resilient, elastic, and message-driven.
  • We are building a realtime Machine Learning engine to continuously adjust the gamification parameters that keep our users motivated and productive.
  • We are always scaling up to handle more data with lower latencies.


Your role in our team


As a Software Engineer, you will be responsible for designing and implementing backend services on existing or new microservices, integrate with third-party APIs, and help run all of this in production. You will work tightly with our frontend developers as well as with our AI Engineers.


You will also be focused on:

  • Developing features in a fast paced startup environment without compromising automated tests or neglecting software craftsmanship
  • Working on our distributed, real-time engine that handles millions of events per day
  • Getting our system ready to scale by one order of magnitude
  • Help the AI team implement distributed machine learning algorithms
