- Work on improving our infrastructure setup in AWS (S3, Dynamo, RDS, ECS, IAM, CloudWatch, Lambda, etc.) using IaC tools like Terraform or Serverless
- Help improve observability, monitoring, and alerting for our services to ensure reliability and quick response to incidents (Sentry, CloudWatch)
- Collaborate with senior engineers to implement best practices for software development, infrastructure, and deployment processes. Participate in code reviews and provide constructive feedback to peers while learning from more experienced engineers

Our take
Rarely does a construction site run smoothly, with countless obstacles appearing unexpectedly. koppla prepares workers for these surprises. A large construction site sees many different companies operating, which can become difficult for construction management and lead to higher costs due to longer construction times. By offering a digital and automate solution, koppla’s software helps management create faster, cheaper and more sustainable construction sites.
There are certainly other players in the construction site optimisation field, such as Munich’s Capmo and Berlin’s Cosuno. Though koppla is unique in its application of the lean methodology in the construction industry. Lean construction management has a reliable history, known for enabling more efficient planning and organisation and better on-site communication.
With funding under its belt, koppla is expanding the technical aspects of its model, as well as making new hires in the tech and sales department as it continues to ambitiously target the top 1,000 construction companies and real estate developers in DACH countries.
