Development Lead

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? 

We're continually challenging ourselves to build great solutions and develop new features to make our shopping experience more enjoyable. Right now we’re looking for Development Leads to be responsible for our newly started teams working with our Delivery Offering and Assortment Offering.

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 .Net Core 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: 

As a Development Lead at Mathem, you’ll lead and manage the developers in an agile cross-functional team of talented Engineers, dedicated to creating a world-class experience for our customers with our web, mobile apps, and supply chain. You’ll have the technical responsibility for the software developed by your team, as well as being the line manager.

Depending on your profile (and interest of course!), you'll either lead the Delivery Offering team, responsible for making sure that our customers can choose suitable delivery slots for when to get their groceries delivered to their doorstep by Mathem’s fleet of trucks - or the Assortment & Pricing team, who aims to understand what assortment we should offer our customers to become their one-stop grocery shop! 

You enjoy a fast-paced environment and put pride in working effectively and with high quality in all aspects of software development. The Dev Lead works closely with the Product Manager to assess, scope, and define the work for the group. As you’re a passionate developer, you are also expected to be an individual contributor to the team. You understand how to balance velocity versus good design and quality and think test automation is important to maintain quality over time.

Who we're looking for:

  • 5+ years of development experience crafting high-scalability, distributed systems in production environments, preferably in C#/.Net Core.
  • BSc or higher in a technology field
  • You enjoy developing and growing people
  • You have some experience in leading a group of people and understand the importance of building relationships 
  • Experience working with microservices and cloud computing (preferably AWS)
  • You understand agile software development and engineering best practices and are keen to advocate these
  • Experience working with CI/CD
  • Experience working with Git
  • Experience in unit testing and mocking
  • Good communication skills, written and orally
  • You have a Swedish work permit

What are some nice to haves?

  • Understanding of relational and non-relational databases
  • Experience taking ideas from concept to production
  • Experience or theoretical interest in Machine Learning
  • Experience working with A/B-testing
  • Experience working with E-commerce
  • Experience working with Observability
  • Experience working with Elasticsearch
  • Experience working with Event-driven systems

...and most importantly, you enjoy developing cool products that make people’s lives easier!

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

Excited about our journey? So are we!
