We Dream. We Do. We Deliver.

At Merkle, a dentsu company, we power the experience economy. Whether we’re building the next great app, running CRM at scale for global brands, delivering technology architectures that support millions of users, or providing world-class data, identity, and insights solutions, it’s all in the name of crafting experiences that set brands apart from the competition. Backed by dentsu's legacy of innovation and creativity originating in Japan, we’ve spent over 35 years helping brands build loyalty, drive growth, and connect meaningfully with their audiences.

We’ve been named a global “Leader” by top industry analyst firms in categories as wide-ranging as digital transformation and commerce, experience design, engineering and technology integration, digital marketing, data science, CRM and loyalty, and customer data management.

You’ll define integration patterns, platform selection, API strategies, and reference architectures, guide delivery teams, and ensure standards for security, scalability, performance, and governance. You’ll partner closely with cross functional teams (solution architects, data engineers, automation engineers, platform SMEs, project managers) and play a visible role in presales, estimation, and Road mapping.

• Strong knowledge of security (OAuth2), observability (logging, tracing, metrics), and nonfunctional requirements (scalability, performance). 
   

• Proficiency in API design (REST/GraphQL), specs (RAML/OpenAPI), and data transformations (DataWeave/JSON/CSV/XML). 
   

• Excellent communication skills—able to present architectures, facilitate decisions, and lead cross functional teams. 

Preferred Qualifications 

• Certifications: MuleSoft (Architecture/Developer), Azure Integration Architect, Workato Enterprise Automation, Boomi Architect.
