Profile Overview
 

We are looking for a Senior DevOps Engineer to join us on a part-time basis to provide expert-level direction and execution for our infrastructure. This is not a "maintenance" role; we need a seasoned professional who can jump into a complex, high-scale environment and immediately begin streamlining it.

We are looking for a specialist who can work autonomously, define "golden paths" and execute high-impact architectural changes (like our cloud consolidation) with confidence.
 

Our Stack: ArgoCD, GitHub Actions, Kubernetes (AWS & Hetzner), Terraform, Ansible, RabbitMQ, Redis, Kafka connect, Debezium (MariaDB → ClickHouse), Infisical.

Your immediate impact in the first 3–6 months will be:
 

• Design and begin the execution of a pragmatic roadmap to move us from a scattered landscape toward a unified single-cloud setup
• Establishing "Infrastructure-as-Code" patterns that allow the rest of the engineering team to move safely without needing constant DevOps intervention
• Improving GitOps + CI/CD reliability so that deployments are boring, predictable, and fast

Your responsibilities:
 

• Platform Leadership: Take lead on the technical direction of our Kubernetes and cloud infrastructure, ensuring we are building for scalability and long-term reliability
• Cloud Migration Strategy: Define the milestones for our cloud consolidation and execute the high-risk migrations safely
• Developer Empowerment: Build "golden paths" (templates, tooling, and docs) that enable full-time developers to self-serve while maintaining high infrastructure standards
• IaC Excellence: Maintain and modularize our Terraform and Ansible codebases to eliminate manual steps and reduce configuration drift.
• Reliability Engineering: Level up our observability (alerts/dashboards) so that the system is easier to monitor even when you are offline.

What you bring to the table:
 

• Strong hands-on experience running production Kubernetes, including real troubleshooting and operational ownership (managed and/or self-hosted)
• Proven experience with GitOps (ArgoCD or similar) and modern CI/CD (GitHub Actions or similar)
• Deep knowledge of Terraform (modules, state management, safe rollouts) and a practical automation mindset (Ansible, scripting)
• Solid understanding of cloud primitives (networking, IAM/security, storage, compute) and distributed system failure modes
• Experience improving reliability for high-scale systems (data-heavy workloads, large storage footprints, worker fleets, microservices)
• You’re proactive and collaborative — you like being close to developers and the business, and you translate platform work into real product impact

• Excellent written and verbal English communication (we collaborate async via Slack/GitHub)

   

Nice to have:
 

• Experience leading a cloud migration / consolidation (multi-cloud → single-cloud, or on-prem → cloud)
• Strong security posture experience (least privilege, secret handling, cluster hardening)

Note on the use of AI:
 

We’re AI enthusiasts and use it daily (Claude Team Premium, ChatGPT Enterprise, Gemini Enterprise). But we’re not “vibe coders”. We use AI thoughtfully — and we take everything that lands in our repositories seriously. Regardless of where code comes from, the engineer is responsible for it.
 

What’s in it for you:

• Ultimate flexibility: We’re remote-first
• Freedom and autonomy: High trust, high ownership, and the space to do your best work
• Real impact: You’ll own a mission-critical area and directly shape the product’s future
• Small, senior team: Work closely with developers and stakeholders; move quickly and ship meaningful improvements
