We are hiring for a USA company:
Senior Database Engineer / Lead DBA (DB2 LUW & Cloud Migration) – Bilingual (EN/PT)
About the Role:
We are seeking a highly skilled Senior Database Administrator (DBA) to join our Global Mainframe DB2 LUW team. This is not a typical application development role;
we are looking for a \"under-the-hood\ " expert who understands database internals, performance optimization, and the complexities of migrating data between NoSQL and Relational environments.
As a technical lead, you will manage high-stakes backend operations, automate audit compliance, and guide the team through complex data mapping and environment refreshes.
What You Will Do
* Core Administration: Perform deep-dive backend management of DB2 LUW (Linux, Unix, Windows) environments.
* Environment Management: Execute test environment refreshes and manage data flow from Archive (AR) environments into active test streams.
* Modernization & Migration: Lead the charge in migrating data from NoSQL to Relational databases, focusing on complex data mapping, relationship building, and schema design.
* Cloud & NoSQL: Manage tasks related to AWS RDS and NoSQL platforms, ensuring high availability and performance.
* Automation & Compliance: Develop automation scripts for audit compliance and security protocols.
* Performance Tuning: Act as the subject matter expert for advanced SQL tuning and database optimization.
* Mentorship: Provide technical guidance and leadership to junior and mid-level engineers.
Required Qualifications
* Language: Native or professional fluency in both English and Portuguese is mandatory.
* Mainframe DB2 LUW
* Expertise in DB2 LUW: Extensive experience in backend DB2 LUW administration (not just interfacing via apps).
* Migration Experience: Proven track record of migrating data between different architectures (Relational vs. NoSQL).
* Cloud Infrastructure: Hands-on experience with Amazon RDS and NoSQL databases.
* Advanced Tuning: Expert-level ability to diagnose and resolve complex SQL performance issues.
* Location: Remote friendly—we value your skillset over your physical location.
