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 Senior Scala 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 focus on

• Playing an integral part in the design and architecture of our gamification platform
• 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
