Recruitment process:

HR Interview (15 min)
A technical interview with an Engineering Manager or the CTO
A code challenge to build a simple API or a SPA. This is used as the basis of discussion for the next step. You can find our challenge on https://github.com/didomi/challenges/tree/master/frontend. We also accept suitable open-source projects in place of the challenge.
A 1h code review session and architecture discussion with 3-4 Didomi engineers
A set of 1:1 30-minute calls with the CTO, engineers, and a product manager

How we build our products:

For the frontend, we have adopted the micro-frontends architecture with single-spa for building our user interface. Each team has the freedom to pick their own framework (Angular/React) for the frontend they need to build. All SPAs we build get plugged into our shell. We also build a multitude of SDKs from Web and Mobile (iOS, Android) to CTV and Unity.
For the backend, we have multiple services (APIs and Lambdas) written in Javascript and Typescript. We leverage PostgreSQL and DynamoDB as our main databases and manage our infrastructure with Terraform and Cloudformation. The principles of infrastructure-as-code are very important to us and we commit everything including KMS-encrypted secrets. Our most important services have 100% code coverage and we deploy our pipeline runners on GCP on a Kubernetes cluster.
We process hundreds of millions of requests per day and are building our analytics platform on Kinesis Firehose, AWS S3 and EMR jobs to provide performant analytics for our clients. Internally we use Athena and Redash
We rely on a multitude of AWS/GCP services for building, deploying, serving, monitoring, and scaling our services. We use Gitlab for our code and CI/CD. To manage our issues we use Jira.

Our vision as a team:

We are building a product and engineering team that is strongly committed to a high level of quality in our products and code. We believe that automation is the key to consistently achieving that along with velocity of development, joy and pride in what we deliver.
At Didomi we are organized into feature teams and work with 2-week sprints. We do our best to avoid pointless meetings. The majority of the engineering team works remotely from all over the world, the only hard requirement is a 4-hour overlap with CET working hours.
We rely on automated tests of all sorts (unit, integration, linters, you-name-it!) and continuous integration/delivery to build flexible applications that are able to evolve without breaking. We trust that it enables engineers to focus on the quality of their code and iterate fast without fears of breaking stuff. And when we break stuff, we fix it and learn from our mistakes.
