We are looking for driven, talented Junior Software Engineers to help us build our SaaS-based anti-money laundering solutions, which help organizations fight financial crime! We are building solutions that help reveal the truth for a safer world and stop money from ending up in the hands of criminals.
As a Junior Software Engineer, you will
- Be working alongside other software engineers within the Tribe.
- Write new features that enable our platform to understand articles in the media, extract information about individuals, apply ML models to categorize their actions, and merge all this with existing data we hold. Your work will allow our customers to find out who has done something bad, what they did, and when.
- Help us deliver new features and maintain our platform as we apply new technologies and scale our systems.
- Learn quickly and be able to adopt the technologies we use to develop code and deploy it to Kubernetes.

- Be responsible for the quality of your code and will be expected to write tests and take ownership of systems that ensure the quality of our code.
- Adopt best practices (and be able to suggest improvements to them), to get code from initial requirements to deployed services in production.
Our Tech Stack:
- Our technology stack is designed to run on public cloud architectures, notably AWS and GCP.
- Development is organized around Kotlin and Python for our backend languages and TypeScript with React for our frontend stack.
- We make substantial use of relational database technologies, notably Postgres, and also use of a distributed SQL database as Yugabyte
- We also use an event-sourced model powered by Kafka for our communication bus and gRPC for our intra-service communication protocol.
- For our data and AI teams, experience in machine learning development and very large-scale columnar data stores (e.g. Apache HBase, Databricks) is key, as well as experience with large-scale data streaming technologies such as Apache Spark, graph databases (e.g. Neo4j, AWS Neptune, TigerGraph)
- We use modern observability solutions built on Grafana Cloud, and deploy our code using ArgoCD
We have a strong emphasis on engineering excellence and strive to ship the best possible code and the best possible solutions to our customers.
About you:

- Motivated in writing production-grade applications and in writing unit tests and understand the importance of testing
- Interested in working with large scalable systems having been exposed to Python as main language
