Cloud Infrastructure Engineer

Description du poste:

Job Description:
Merkle powers the experience economy. For more than 35 years, we've put people at the heart of digital business transformation. As the world's only integrated experience consultancy with a strong heritage in data, technology, and business performance, we deliver end-to-end customer experiences that drive growth, engagement, and loyalty.
With more than 16,000 employees across 30+ countries, Merkle supports global brands at scale. In Bulgaria, we work on complex international commerce platforms, acting as a central delivery hub for technology, engineering excellence, and operational support.
Our Commerce practice has a proven track record of delivering and evolving large-scale, multi-market e-commerce ecosystems for leading global brands and retailers. We are now expanding this capability further and are looking for a Cloud Infrastructure Engineer to join our team in Sofia.

Role Overview
The Cloud Infrastructure Engineer is the senior technical owner of Merkle's cloud platform architecture. The role focuses on designing, building, and evolving the cloud foundations, guardrails, and platform capabilities that underpin client operations - ensuring environments are reliable, secure, and well-governed.
The role is a hands-on specialist position. It sets the direction for how cloud infrastructure is designed, built, and hardened across client accounts, and provides deep technical input on complex incidents, major changes, and architecture-impacting decisions. People leadership, resource allocation, and day-to-day team direction sit with the Engineering Director.

Responsibilities

Cloud Infrastructure Engineering
* Architect and build cloud foundations and platform capabilities across client environments.
* Define secure-by-design patterns, guardrails, and platform standards for Cloud Operations to operate within.
* Design resilience and continuity architecture, including backup/restore strategy and disaster recovery.
* Own and evolve infrastructure-as-code (IaC) practices and tooling standards.
* Drive continuous improvement of the platform approach, ensuring it evolves with client needs and industry practice.
* Provide specialist guidance to Cloud Operations Engineers during complex incident investigations, major changes, and architecture-impacting decisions.
* Assess and respond to critical CVEs and security advisory items, coordinating with dentsu EMEA security where required.

Operational Governance
* Define platform-level patterns that support incident management, change management, SLA governance, and on-call practice.
* Provide senior technical input on P1/critical incidents and client-impacting situations where infrastructure or platform expertise is needed.
* Ensure platform ownership responsibilities are clearly defined and applied - Cloud Ops owns production stability; Cloud Infrastructure owns design and evolution.
* Maintain platform design standards that support audit-readiness, NIS2, and client contractual obligations.
* Contribute to operational reporting quality, including platform health signals and SLA-relevant metrics.

Client & Stakeholder Engagement
* Act as senior technical point of contact for client escalations requiring infrastructure or platform expertise.
* Collaborate with Project Managers and delivery teams on change planning, release readiness, and deployment governance.
* Contribute to account-level technical conversations, including architecture reviews and SLA design.
* Support pre-sales and proposal work where infrastructure architecture or managed operations expertise is required.

Scope Boundaries

This role does not own day-to-day operational ticket triage, routine monitoring, or first-line incident response - those are owned by Cloud Operations Engineers and Support Engineers. People management, resource allocation, performance, and development of the Infrastructure & Operations team sit with the Engineering Director. The Cloud Infrastructure Engineer focuses on platform architecture, guardrails, IaC standards, and critical-path technical input.

Required Experience & Competencies
* Proven experience architecting and running cloud infrastructure in a professional services or managed operations context (Azure/AWS/GCP).
* Strong IaC proficiency (Terraform, Bicep, or equivalent) and understanding of secure-by-design cloud patterns.
* Deep understanding of ITIL/ITSM practices: incident management, change management, problem management, and SLA governance.
* Experience handling critical escalations and acting as a senior technical interface with clients.
* Ability to work across both strategic platform design and hands-on technical input when required.
* Comfortable operating in a multi-client, commercially governed environment with contractual obligations (SLAs, NIS2, data processing).
* Strong written and verbal communication skills in English; Danish is an advantage.

What We Offer
* Work on complex, international commerce platforms for well-known global brands.
* A collaborative, engineering-driven culture with strong technical leadership.
* Flexible working arrangements and modern office environment in Sofia.
* Access to continuous learning, certifications, and career development within dentsu / Merkle.
* Competitive compensation and benefits package.
