Job Description

Our “Devices team” is responsible for the command and control of our IoT fleet. This includes monitoring and interacting with devices, securing communications and preprocessing sensor data. You will work closely with firmware and hardware engineers to develop interfaces between the embedded systems and our data processing architecture. Your focus will be squarely set on the development and operation of software services, taking ownership across the full SDLC.


  • Process and enrich incoming IoT sensor data, to make it readily usable for downstream services.
  • Automate systems to monitor and adapt behaviour of IoT devices.
  • Investigate cases of anomalous behaviour of devices in the field (3rd level support).
  • Conduct technical requirements analysis, including functional and non-functional requirements (e.g. security, availability, scalability, cost-optimization, ...) and incorporate this in the implementation.
  • Help maintain and operate existing systems: implementing features, bug fixes, refactoring and version upgrades.
  • Act as an onboarding buddy for new team members.


  • 3 years’ of experience developing backend applications - ideally in JVM languages (we use Kotlin!).
  • Demonstrable experience in distributed system design, with a focus on architecture and APIs (REST/gRPC).
  • Although a University degree in Computer Science/Electrical Engineering or any related technical field isn’t a requirement, it certainly is an advantage.
  • Willingness to take ownership of projects throughout the design, implementation, testing and operation phases.
  • The ability to work independently in a dynamic environment.


  • Experience in writing JVM based software (we use Kotlin & Java).
  • Familiar with concepts, patterns and technologies like SQL (PostgreSQL), NoSQL (DynamoDB), Message Queuing (SQS), Publish & Subscribe (SNS & Apache Kafka), Twelve-Factor App, Serverless (AWS Lambda) and Containerized (Docker) workloads.
  • Well acquainted with the Git version management system (Gitlab) and CI/CD best practices (Gitlab pipelines).
  • Experience in writing and operating containerized software services.
  • Prior experience working with Kubernetes, AWS ECS, AWS Fargate or Docker is a great plus.
  • In addition to the above skills, Python, PHP and Linux/Unix shell know-how is “great to have” but not a necessity.
