About Us;

We’re big believers in autonomous teams and iterative development. We’re crazy about continuous improvement and knowledge sharing, and we want people who share our enthusiasm.

We strive to always build the right thing and build the thing right, so we place great emphasis on code quality and testability, test driving, continuously integrating and pairing as we go. We think functional programming and event sourcing are a great fit for Foundry, and use them as best we can, but we’re not dogmatic about it.

We make designing the product everyone’s business - what we are going to do and how we do it are team decisions. And we focus on meeting exactly what the customer needs now, always aiming to build the minimum lovable product.

We strongly believe that you grow a system, rather than build it, so our architecture and infrastructure is designed to allow us to roll small bits of code to production really fast. And really often.

We build our platform with tech like:

- Scala & the Typelevel ecosystem - cats, http4s, Cats-effect & tagless final 

- Event-sourced microservices

- Cloud deployments - GCP, Docker, Kubernetes, Concourse

- High-performance data & messaging - Postgres & Kafka

- Observability - Grafana, Jaeger & Prometheus 

About you;

We are looking for skilled Scala engineers to help build Foundry.  You’ll be a key player in our team, building out new products and features of the platform. 

Building high performance, scalable, available, fault tolerant systems is a team game and so we want to know that you play well with others. Lone geniuses are brilliant - just not for us. 

As a Senior Backend Engineer your role will include:

- Developing high quality, tested services

- Knowledge sharing with other team members

- Collaborating in the design of new features

- Making strategic architectural improvements to the Platform

- Cross-functional working with platform and frontend engineers

- Proactively monitoring and support production deployments
