The Role

We are looking for an experienced and versatile Platform Engineer to take a central role in building and operating our infrastructure, CI/CD pipelines, and backend services. In this role, you will be the backbone of our platform, ensuring our services are scalable, reliable, and secure on our European cloud infrastructure.

This is a high‑impact role where you will have significant autonomy. You will be responsible for both building new features and keeping the lights on. We value a "you build it, you run it" philosophy, and you'll have the opportunity to work across the stack, from our Kubernetes clusters to our Python backend.

What You'll Do

Design, build, and operate our cloud infrastructure on a European cloud provider, with a focus on Kubernetes.

Take ownership of the services you build, with hands‑on operational responsibility for the entire platform. This includes monitoring, incident response, and performance tuning—we are a small team without a separate ops department.

Develop and manage our Infrastructure as Code (IaC) using Terraform and Helm .

Automate, manage, and optimize our CI/CD pipelines for all services.

Contribute to the development of our backend services written in Python (FastAPI, Django) .

Actively contribute to key Open‑source projects that our platform relies on.

Our Tech Stack & What We're Looking For

We're looking for someone with strong hands‑on experience, particularly in the following areas:

Kubernetes: Deep, hands‑on experience managing and operating production workloads.

Infrastructure as Code: Proficiency with Terraform and Helm is a must.

CI/CD: Proven experience building and maintaining automated pipelines (e.g., GitHub Actions, Circle CI).

Python: Strong proficiency, with professional experience in web frameworks like FastAPI or Django .

Containerization: Expertise with Docker for building and deploying applications.

Cloud Platforms: Experience with a major cloud provider (e.g., AWS, GCP, Azure) and a strong interest in working with European alternatives.

Ideal Experience (Nice‑to‑Have):

• Experience with systems design and software architecture for scalable services.
• Open Source Contribution: A track record of contributing to Open‑source projects is highly valued.
• Databases: Experience with PostgreSQL .
• Observability: Experience with monitoring/logging tools like Prometheus, Grafana, Loki, or the ELK stack, SIEM Tools.
• Security: A strong understanding of cloud and application security principles (our platform uses RBAC and token‑based auth).

About You

You are a proactive self‑starter who thrives in a dynamic startup environment.

You have a "you build it, you run it" mindset and are comfortable with the hands‑on operational tasks that come with owning a platform.

You are passionate about learning and are not afraid to dive into new technologies.

You have a genuine interest in data privacy, anonymization technologies, and the sovereign cloud ecosystem.
