About this role

Backend Software Engineers at Dealfront work mainly on building APIs, background data processing flows, and integrations. Being a very data-intensive application, much of the work on the backend involves optimising and effectively using various databases - AWS RDS & Aurora, AWS DynamoDB, Elasticsearch and Redis, to name a few.

Our backend consists of multiple small-to-medium sized Ruby and Ruby on Rails apps combined with Serverless components (AWS Lambda, API Gateway, Kinesis, SQS) on the side. We pride ourselves on keeping apps working smoothly, and the codebase tidy and well-tested. We dedicate time for upgrades, refactoring, and overall improvements for developer productivity and happiness.

For people with skills and interest, we offer possibilities to work on our Ember.js frontend too, enabling people to grow into a fullstack role. Equally, there are opportunities to learn and be involved in the infrastructure, DevOps and serverless development.

Role description

Being part of the Backend development team involves working with a broad series of components and technologies. These include (but are not limited to): data pipelines and systems built with serverless and streaming technologies, or the internal data services used across the platform.

Curiosity and passion to constantly learn new things is also a key part of this role. We are always looking to improve how we work and what tools we use. We dedicate time to research and test new technologies in order to improve our systems and make them work more efficiently and reliably.

What you’ll work on:

• Work with streaming and serverless components supporting the data collection pipelines such as AWS Kinesis and AWS Lambda.
• Work optimising and storing effectively all the data we collect, using various databases such as DynamoDB, AWS RDS & Aurora, OpenSearch/Elasticsearch or Redis.
• Build internal applications mainly in Ruby, running in Kubernetes or AWS and communicating with gRPC, event-based and streaming technologies.
• Provide code reviews to your peers

• Expertise with Ruby and willingness to learn our stack. 
• Interest in building scalable Serverless systems using AWS technologies such as Lambda, Kinesis and API Gateway.
• Understanding how to model and build applications using microservices architecture patterns. If you have experience with Kubernetes and gRPC, even better!
• Strong software architecture & data modeling skills to base engineering decisions on product vision
• Experience in DevOps and Infrastructure is a plus, especially in AWS, Terraform, Docker, and Kubernetes
• Ability to help and improve the work of your colleagues through your teamwork and communication skills
• Experience managing, monitoring and troubleshooting production-grade web applications
• Be physically located within European timezones
