Full Stack Senior Engineer

Luzern, Switzerland

Overview

EF is investing in new software innovation products for the next generation of education experiences. We are modernising our tech stack and our development processes; and building a strong team of engineers to completely own code and infrastructure for our B2B products. We’re
looking for individuals who love to grow and solve new and interesting problems.

We’re not overly obsessive about tech stacks that you may have used - but value any experience with building modern, dynamic and complex applications.


The Team and Our Stack

We are responsible for the development, maintenance & deployment of the EF B2B Online School.

We are mostly based in the UK and Switzerland.

We run our system on top of AWS - we use EKS (Kubernetes cluster), RDS, MSK, Elasticache and Elasticsearch.

Our backend services are mostly implemented in Java (Vert.x) and Node.js (NestJS).

Our frontend is mostly implemented in Elm and React.

For mobile development we use Swift/Objective-C for iOS, Kotlin/Java for Android, and we’re starting to look into React Native.

We use Github both for source control and CI/CD (Github Actions).

We deploy using Terraform & Helm.

We do data processing using Kafka and Storm.


The Role

We are looking for a talented engineer to help build & maintain applications across the board, from single-responsibility backend services (microservices), to smooth user-facing UIs. You will be a part of a team which values quality, code coverage and good code design.

You will contribute to our backend services, frontend apps and architectural decisions regarding the system. We understand nobody is an expert in everything and everyone has their own area of expertise. This role is defined as full stack but it’s fine if you feel more comfortable in just one part of the stack; as long as you’re willing to learn and participate in other parts of it (see list of technologies below).

  • Work with other engineers to implement features.
  • Triage issues, debug the system and fix bugs.
  • Break down complex problems, into simple solutions.
  • Drive yourself to understand the context and the system in which your code operates.

  • Work with existing code bases and learn the mechanics of existing applications and data flows.
