Senior MultiCloud DevOps/ Platform Engineer with Harness

While Xebia is a global tech company, our journey in CEE started with two Polish companies – PGS Software, known for world-class cloud and software solutions, and GetInData, a pioneer in Big Data. Today, we’re a team of 1,000+ experts delivering top-notch work across cloud, data, and software. And we’re just getting started.

We work on projects that matter – and that make a difference. From fintech and e-commerce to aviation, logistics, media, and fashion, we help our clients build scalable platforms, data and AI solutions, and cutting-edge applications to shape the future of tech. Our clients include McLaren, Aviva, Deloitte, Spotify, Disney, ING, UPS, Tesco, Truecaller, AllSaints, Volotea, Schmitz Cargobull, Allegro, InPost, and many, many more.

We value smart tech, real ownership, and continuous growth. We use modern, open-source stacks, and we’re proud to be trusted partners of Databricks, dbt, Snowflake, Azure, GCP, and AWS. Fun fact: we were the first AWS Premier Partner in Poland!

What makes Xebia special? Our community. We support tech communities, organize meetups (Software Talks, Data Tech Talks), and have a culture that actively support your growth via Guilds, Labs, and personal development budgets — for both tech and soft skills. It’s not just a job. It’s a place to grow.

We are looking for a Senior DevOps / Platform Engineer with strong experience in modern CI/CD practices and cloud-native delivery. You will lead the design, implementation, and operation of delivery pipelines, infrastructure templates, and platform capabilities supporting applications across AWS/Azure/GCP environments. 
A core responsibility for this role is owning and operating the Harness platform (CI/CD, Feature Flags, Cost Management), and enabling engineering teams to deliver fast, safe, and reliable deployments. 

• designing, implementing, and maintaining Harness pipelines for Kubernetes, ECS, serverless, and VM deployments, including canary/blue‑green strategies and automated rollbacks, 

• operating CI pipelines and shared build infrastructure, improving build performance and developer feedback loops, 

• configuring and managing Feature Flags to support progressive delivery and experimentation, 

• integrating Harness SRM/Chaos (if applicable) to support deployment verification, resilience testing, and error budget policies, 

• partnering with FinOps to leverage cost dashboards, budgets, and guardrails for cloud spend optimization;

• creating reusable pipeline templates, governance controls, and “paved roads” for application teams, 

• implementing secrets management, artifact versioning, and environment promotion flows (dev → test → staging → prod), 

• standardizing infrastructure provisioning with Terraform, Helm/Kustomize, CloudFormation, and ARM/Bicep, 

• supporting Git-based workflows (GitHub, GitLab, Azure Repos, Bitbucket) and applying GitOps practices (Argo CD/Flux) where appropriate; 

• embedding automated tests, security scans (SAST, DAST, dependency/image scanning, SBOM), and quality gates into CI/CD pipelines, 

• enforcing RBAC, least privilege, SSO/SCIM, and audit readiness across platforms, 

• contributing incident response, post-incident reviews, and the continuous evolution of SLIs/SLOs, 

• integrating observability systems (Prometheus/Grafana, OpenTelemetry, Datadog, New Relic) into deployment verification and runtime dashboards, 

• optimizing reliability, building performance, caching, architecting storage, and runtime platform performance; 

• onboarding product and engineering teams onto the Harness platform,

• running enablement workshops, producing documentation, and maintaining self-service resources,

• measuring and reporting delivery metrics such as lead time, deployment frequency, change fail rate, and MTTR — and driving improvement initiatives based on these insights.
