Job description

Overview

Using AI, you need to design, develop, debug and resolve software problems for Oracle database areas, esp. in the Scalability and performance areas. Strong database domain knowledge and programming background is a must. Customer escalation management experience should come naturally to the candidate for this job.

This role requires developer to have proven ability to utilize AI solutions and work collaboratively across global teams. As a member of the software engineering division, you will take an active role in the definition and evolution of standard practices and procedures. Are you interested in a dynamic working environment where you are constantly presented with new challenges where you need to devise smart solution keeping performance and functionality aspects intact? Do you enjoy fast-paced problem solving and working to improve product architecture and functionality? Would you like to see how customers use products in all sorts of unexpected ways? If so, this job could be for you!

The Database Sustaining Engineering organization is considered the go-to team for all aspects of product experience at Oracle both on Cloud and on-premises environments. We\'re best known for diagnosis and resolution of problems in just about all the Oracle Server Technologies product areas and doing the product enhancements related to improving resilience and diagnostics of the product. We are also in the forefront in adopting GenAI in the workflows and delivered solutions related GenAI based problem triage, summarization, monitoring, anomaly detection, etc. When the Oracle Support or Cloud Operations organizations need additional assistance in solving a Cloud or customer-reported product problem, they come to us to fix it at the source code level. Often the stakes can be high: a production system is down, an upgrade or new application roll-out is delayed.

Oracle software powers the engines of almost all the best-known companies, so millions of dollars can be at risk if it fails. Almost all the Fortune 500 companies and major Airline reservation systems, Banking and Financial systems, Telecommunication systems, Online shopping/E-commerce, Factories/plants operations, etc. run on Oracle software, and these complex systems depend on swift resolution of problems. Our developers, many of whom have been with us for ten years or more, are able to piece together clues from the failures and produce resolutions, thereby improving the product quality. For a member of this team, it can be exceedingly gratifying to see the immediate result of our solutions. Variety and fresh challenges are defining features of our work.

This is a Customer Focused Engineering work environment and it is technically challenging and rewarding: you need to understand complex code fairly quickly. You have to be able to conceptualize the interaction of software components and products together in a stack. You need to be prepared to expect the unexpected and have a strong focus on customer satisfaction. We\'re looking for people who are fast learners, highly motivated, and have great communications skills. If the opportunity to resolve real-world customer problems and rework architecture and functionality in the world\'s most important software products looks exciting to you, then come join us. You can be guaranteed never to be bored!
