Job description

Who are we?

At Vertiv, we’re on a mission to empower the people who will power the future. From a simple swipe to life-changing medicines, from push notifications to generative AI. We design, manufacture, and service the products and solutions that keep the world connected. With $6.9 billion in sales, a strong customer base and global reach spanning nearly 70 countries, we are uniquely positioned to deliver greater value to our customers and create new opportunities for our people.

Position Overview: We are looking for a Customer Portal Full-Stack Senior Developer to join our global Customer Portal team, which is responsible for continually adding new capabilities to a custom-built global portal that serves as the primary digital touchpoint between Vertiv and many of the largest companies in the world.

As the team’s senior developer, you will work closely with product managers, UX designers, and integration architects to ensure solutions meet business requirements, bridge technical gaps, and align with modern development best practices. You will utilize Oracle Visual Builder and Oracle Integration Cloud (OIC) to deploy new functionality for Vertiv’s global customers. You’ll work within a Oracle-based architecture that includes Oracle E-Business Suite (EBS), Oracle Autonomous Transaction Processing (ATP),and Snowflake.

Your day-to-day work will include hands-on technical design, coding, code reviews, prototyping, and maintaining clear technical documentation.

Conduct code reviews to ensure adherence to development best practices and alignment with team standards.

Collaborate closely with the QA lead by contributing to test coverage, unit testing, and debugging to ensure high-quality, stable releases.

Own and maintain technical documentation for developed features, including APIs, architecture decisions, and data models.

Proactively identify technical debt and advocate for continuous improvement within the codebase and development processes.

Stay current on updates to Oracle Visual Builder and Visual Builder Studio and related technologies and share this knowledge with others.
