About the Team

You will join an operations and development team.

Deployment for our CRM is currently handled by a dedicated DevOps team using GoCD pipelines, Ansible, and virtual machines across multiple data centers. We are currently using Docker, Docker Swarm, and Portainer for our test environments.

Deployment for our ai platform is GitOps-driven via ArgoCD and Kustomize on Kubernetes, with Jenkins/Harbor for CI and HashiCorp Vault (External Secrets Operator) for secrets. Cilium CNI with BGP Control Plane handles networking across prelive and live clusters. Local environments use Docker Compose, elastic search, ClickHouse, MinIO, and Redis; Langfuse runs across all environments with ClickHouse as its backend.

We want to move toward a more dynamic infrastructure model, potentially based on Kubernetes for all our systems where possible. Our goal is to gain speed in spinning up environments for testing purposes but also more flexibility in a potential hybrid production environment.

You will work alongside our existing DevOps team and experienced engineers, who will support you as you grow into the more advanced parts of our stack.

Role Overview

We are looking for a DevOps Engineer with around 3–5 years of experience who will work directly with the development teams and take an active part in the next stage of our infrastructure.

This role combines hands-on Linux administration, container orchestration, networking knowledge, and modern DevOps practices. You will help us move from VM-based deployments toward a more scalable, orchestrated platform.

Responsibilities

  • Build, maintain, and improve CI/CD pipelines in collaboration with development teams
  • Contribute to the gradual move of our infrastructure toward container orchestration, potentially based on Kubernetes
  • Maintain and optimize Debian-based Linux systems
  • Help ensure high availability and monitoring across multiple data centers
  • Support telephony and real-time AI integrations from an infrastructure perspective
  • Contribute to observability, logging, and incident response practices
  • Automate infrastructure provisioning and configuration
  • Take part in the team's on-call rotation
  • Help maintain security across the infrastructure: ISO security standards, vulnerability handling, and dependency tracking
  • Work closely with developers to optimize deployment workflows and runtime environments
  • Use AI tooling effectively (Claude, ChatGPT, internal MCP tools) to improve productivity and automation

Required Skills and Experience

  • Solid Linux administration experience, preferably Debian-based systems
  • Hands-on experience with Docker in production environments
  • Working knowledge of Kubernetes fundamentals and deployment mechanisms
  • Good understanding of networking fundamentals (TCP/IP, DNS, routing)
  • Experience with CI/CD systems and infrastructure automation tools
  • Good scripting skills (Bash, Python or similar)
  • Good Ansible skills
  • Structured approach to troubleshooting across multiple services

Nice to Have

  • Experience migrating from VM-based infrastructure to container orchestration
  • Experience with cloud native architectures (design, build, operations)
  • Exposure to GitOps tooling such as ArgoCD and Kustomize
  • Exposure to HashiCorp Vault or other secrets management tools
  • Knowledge of BGP or Cilium networking
  • Experience operating systems across multiple data centers
  • Exposure to AI-driven development workflows

What We Offer (as a team)

  • Direct involvement in building AI-powered customer interaction systems
  • The opportunity to contribute to our infrastructure architecture
  • Hands-on experience with a modern Kubernetes and GitOps stack, with support from experienced colleagues
  • A technically mature environment with strong availability requirements
  • Close collaboration with development teams

If you are comfortable working close to developers, enjoy building resilient systems and want to help build a stable infrastructure, this role will give you space to grow and make a measurable impact.

What we offer (as a company)

  • Access to local/international trainings, development and growth opportunities, including access to e-learning platforms, covering both technical and soft skills areas;
  • Modern technologies, product responsibility;
  • Flexible work schedule;
  • Hybrid work option;
  • Medical services package from one of two private providers;
  • 25 vacation days per year;
  • Substitute days off for public holidays that occur on the weekend;
  • Meal tickets;
  • Internal referral program;
  • Team events, networking events organized to promote a passionate, creative and diverse culture;
  • Summerfest and Winterfest parties;
  • Of course, coffee, soft drinks and fresh fruits are on us in the office.

Diversity enriches:

Different cultures, nationalities, genders, age groups, sexual orientations, and religions as well as people with disabilities - we encourage diversity. Because only teams that reflect all facets of society offer the best framework conditions for creativity and make a company productive and distinctive. We value diversity and welcome all applications.

Application Note

We value diversity and welcome all applications – regardless of, for example, gender, nationality, ethnic or social origin, religion, disability, age as well as sexual orientation and identity, physical characteristics, marital status or any other irrelevant factor subject to applicable law.
