90 – 119 PLN/hour (B2B)

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.

This is a contractor engagement for a DevOps / Cloud Infrastructure professional who wants to work on impactful, hands-on challenges with real technical depth and a lot of cross-company collaboration.

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

About You

Solid hands-on experience in infrastructure engineering and in designing and running cloud environments
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

Nice to have:

Experience with IoT, automotive, or other remote device integrations
Experience as a backend engineer or full-stack developer, ideally in the JVM ecosystem
Familiarity with Linux and virtual machines

Collaboration Model

Contract type: Cooperation based on a service agreement (B2B/freelance contract), not an employment contract
Working model: Independent contractor responsible for delivering agreed services and submitting invoices
