Does this inspire you and feel like a fit? Then we would love to have you join us

At Genmab, we're building something transformative, and like any lasting structure, it starts with a strong foundation.

We are looking for a Senior Infrastructure Architect to be the crucial link between business needs, technical infrastructure, and cloud security. Someone who understands the full journey from laptop to cloud.

The Role 

As our Senior Infrastructure Architect, you won't just design IT systems, you will build the roadmap that brings together people, processes, and technology. This role combines hands-on expertise, strategic oversight, architectural design, and stakeholder engagement to guide how we deliver secure and scalable infrastructure, both on-premises and in the cloud (Azure, AWS, SaaS). 

You will work closely with engineering, business teams, and external partners, helping translate business needs into solid, secure, and future-proof architecture. Think of it as building a house: you will ensure the structure is sound, the plumbing secure, and the tech stack aligned, whether we are expanding an office, moving to the cloud, or enabling a new lab setup. 

The role is approximately 20% hands-on (as outlined in responsibilities below) and 80% focused on architectural work, translating evolving business needs into resilient and scalable infrastructure solutions.

Responsibilities 

• Design and lead infrastructure solutions across cloud, lab, and corporate systems. 

• Build secure and scalable architectures in Azure, AWS, and hybrid environments. 

• Translate business and security needs into technical architecture. 

• Be a day-to-day consultant: meet with internal stakeholders (engineers, business, vendors) and guide project decisions. 

• Engage with a fixed list of ongoing projects and support office expansions from an IT infrastructure standpoint. 

• Set cloud governance and security best practices, you will be the one ensuring our structure is sound. 

• Participate in CAB (Change Advisory Board) meetings to present architecture decisions. 

• Mentor and guide the team, which includes 12 direct colleagues and around 150 consultants. 

• Speak up, whether it's making a case for a solution or explaining how things connect, we value someone who can communicate clearly and compellingly. 

Who You Are 

• A true consultative architect, someone who sees the big picture and knows how to bring people together around it.

• Comfortable in meetings, confident in presenting, and curious enough to ask "why?". 

• Not afraid to challenge assumptions with thoughtful technical arguments. 

• Strong in stakeholder communication – from engineers to vendors to leadership. 

• Well-versed in IT, security, and modern infrastructure topics including SSO, IAM, Zero Trust, IaC (e.g., Terraform), networking, Windows, Azure AD, and SaaS platforms. 

 Requirements 

• Minimum 8 years of technical infrastructure experience, with a proven track into architecture. 

• Hands-on background, not just PowerPoint-level architecture. 

• Located in the US or Denmark and able to work onsite at our office. 

• Strong experience with cloud (Azure, AWS), SaaS, Microsoft systems, and security architecture. 

• Comfortable bridging technical knowledge with business objectives. 

• Certifications such as Azure Solutions Architect Expert, AWS Certified Architect, or ITIL are a bonus. 

• Please note that relocation support is not available for this position.
