- We are looking for a DevOps / Cloud Infrastructure Engineer for service agreement collaboration (B2B contract) to cooperate with a team that connects Flix's cloud platform with the new train fleet.

About Flix
90 – 119 PLN/hour (B2B)
Responsibilities
- Scope of Services
- You will help shape an architecture from the start, make sure it is secure and reliable, and take it all the way to production.
About the Engagement
- Design, build and operate the cloud infrastructure that connects onboard train systems with Flix's backend services, covering telemetry ingestion, alerting, video streams and remote content delivery
- Build and maintain the infrastructure-as-code foundation of the platform, keeping the Terraform/Terragrunt codebase clean, scalable and easy for others to work with
- Steer technical proposals and topics across backend and infrastructure, from the first idea and design discussion to a working solution in production
- Take part in system design and architecture discussions and constructively challenge architectural decisions when you see a better path
- Define and implement secure communication between the trains and the cloud, including mTLS, certificate management and network design
- Work closely with train manufacturers’ engineers to agree on interfaces, protocols and responsibilities on both sides of the integration
- Collaborate with backend developers and other Flix teams so that new services are deployed reliably and are easy to run and monitor
- Make sure the platform is reliable, observable and secure, so that we know what is happening in our systems before our users do

- Experience with AWS (preferred). Experience with any other major cloud platform is also welcome
- Strong knowledge of Terraform/Terragrunt for infrastructure provisioning and automation
- A solid understanding of systems architecture and system design, and the confidence to challenge architectural decisions with clear arguments
Good knowledge of networking, including mTLS and SSL/TLS
- Foundational knowledge of security and the ability to apply it in everyday infrastructure decisions
- Proven ability to lead technical proposals and topics across backend and infrastructure, and to bring your stakeholders along with you
- Strong critical thinking, including the ability to analyze a problem, weigh trade-offs and explain your reasoning clearly
