About us

Start-up

We are looking for a Senior DevOps Engineer with at least 10 years of experience in building secure, scalable, and fully automated infrastructure environments. You will play a key role in designing and operating our PAAS and data infrastructure, supporting a fast-moving, AI-driven engineering organization.

Your role

As a Senior DevOps Engineer, you will architect, implement, and maintain modern cloud-native infrastructure. You will build scalable and secure environments, optimize CI/CD pipelines, and drive automation across all layers of the platform. You will collaborate closely with backend, data, and product teams to deliver high-throughput and data-intensive systems, while shaping our big data and observability landscape. You will also be a key driver of a strong DevOps culture, emphasizing automation, ownership, and continuous improvement.

Key Responsibilities

  • Architect, implement, and maintain scalable, secure, and highly available infrastructure.
  • Manage cloud-native and PAAS deployments using Kubernetes, PostgreSQL, Redis and similar technologies.
  • Define and implement Infrastructure as Code (Terraform, Pulumi, Crossplane).
  • Build and optimize CI/CD pipelines supporting TDD and AI-assisted development workflows.
  • Monitor, automate, and scale systems for performance, reliability, and cost efficiency.
  • Lead infrastructure security, compliance, and vulnerability management.
  • Work closely with backend, data, and product teams on high-throughput and data-driven systems.
  • Design and operate Big Data infrastructure (batch/streaming, analytics, ML workflows).
  • Establish observability best practices (metrics, tracing, logging).
  • Lead incident response and post-mortems with a continuous improvement mindset.
  • Drive DevOps culture across the organization.

Your profile

  • 10+ years of experience in DevOps or infrastructure engineering.
  • Proven experience building cloud-native infrastructure from scratch (AWS, GCP, or DigitalOcean).
  • Strong background in security engineering, zero-trust principles, and compliance.
  • Expertise with Kubernetes, containerization, and distributed systems.
  • Deep knowledge of Infrastructure as Code (Terraform, Pulumi, AWS CDK, etc.).
  • Experience building and managing CI/CD pipelines (GitHub Actions, GitLab CI, etc.).
  • Hands-on experience with PAAS platforms and multi-environment deployments.
  • Strong understanding of performance optimization for data-heavy workloads.
  • Familiarity with Big Data ecosystems (Kafka, Spark, Flink, NATS, ClickHouse, etc.).
  • Experience with observability stacks (Prometheus, Grafana, OpenTelemetry).
  • Strong understanding of TDD, DevSecOps, and integration into CI/CD pipelines.

What we offer

  • Competitive salary aligned with seniority.
  • Flexible remote or hybrid working arrangement.
  • Opportunities for innovation, experimentation, and technical leadership.
  • Annual training and certification budget.
  • Strong pension and paid leave package.
  • Work with cutting-edge AI-driven technologies and modern tooling.

About us

You will join an innovative, AI-driven engineering organization focused on building reliable, scalable, and future-proof platforms. The company emphasizes security, performance, and automation. You will work with experienced engineers and contribute directly to the foundations of a modern PAAS and data infrastructure.
