Software Developer - ElasticSearch

Did you know that we at Mathem are working with pure cloud serverless architecture and modern microservices? Interested in working with a cool innovative product that blurs the line between online/offline and having a direct impact on the end-users by making their everyday lives more comfortable? 

Speaking about convenience, our search at our website increases our customer experience by facilitating finding the right products. In this role, you'll be our wizard in the Elasticsearch engine; leading, developing, and creating best practices. Thus, you're not only working towards the end goal of saving our customers’ time by not having to go to the grocery store but also directly shorten the time they have to spend placing the orders.  

This is why you should join us!

At Mathem we’re working with pure cloud serverless architecture and modern microservices. We develop new functions in C# or node.js on AWS Lambda, use DynamoDB table that triggers events on updates that other services can consume, and automatically deploy to our test and production environments using AWS CodePipeline. We strive to continuously nurture a curious and forward-leaning approach to software development, evaluating new technologies as well as open-source. We have a “you build it, you run it” way to develop and operate our software, which includes developers to develop test automation and deploy the code to production.

You’ll be part of a creative and helpful environment with a lot of heart. Our international environment consists of skilled yet humble people, who love to share their knowledge. When you want a break, there’s probably a colleague up for a game of table tennis or a coffee, or you could just fill your inspiration with the beautiful view of Skeppsholmen. We’ll believe in you and have a great openness to your thoughts and way of working, and we’ll always aim for you to be comfortable being yourself! 

What you’ll do: 

In this role, you'll be part of the team working with the products and recipes on the website. You'll be the expert and have a focus on the highly prioritized Elasticsearch. You'll set up Elasticsearch clusters from scratch as well as maintaining and managing them. As the expert on the subject, you'll also be the go-to person and educate others in the team on Elasticsearch. 

The role is mainly backend but if you have an interest in working frontend as well we're open to a full-stack role. 

What we're looking for:

  • Experience and preference in working in C#
  • Experience and good knowledge of Elasticsearch
  • Experience in one of the CI/CD tool, such as GitLab, GitHub, or similar
  • Experience in unit testing and mocking
  • Agile way of thinking based on Scrum/Kanban
  • A balanced way of thinking with respect to both technical excellence and business goals
  • Work permit in Sweden

We'd also prefer if you have:

  • Hands-on experience with AWS
  • Experience in working with distributed systems

At Mathem we generally use this tech stack: 


  • A 100% serverless microservice architecture built on AWS services including Lambda, DynamoDB, API Gateway and EventBridge
  • Bounded and pragmatic contexts 
  • Managed services if no serverless (e.g Elasticsearch) 
  • Infrastructure as Code (CloudFormation & SAM) 
  • Observability (Kibana & CloudWatch for logs and Datadog for dashboards, alerts, and metrics)


  • Analytics (BigQuery, Google Analytics, Google Optimize, GTM, and our own data from AWS) 
  • ML (we also use SageMaker in AWS) 
  • Datahem

Coding languages (agnostic mindset in general even though C# is the tool for this specific role)

  • .NET Core 
  • NodeJS 
  • Python
  • Angular 
  • React 
  • Swift 
  • Kotlin
