12d•$90,000 - $158,400

About The Position

We are seeking an experienced Oracle Database Developer to design, optimize, and scale our core systems. In this role, you will embed critical application business logic directly into the Oracle database layer by writing high-performance PL/SQL code and tuning complex queries. While your primary expertise lies in database engineering, a strong foundational knowledge of modern Java backend development will allow you to seamlessly bridge the gap between our data and application tiers.

Requirements

Deep, hands-on experience with Oracle Database versions (e.g., 19c / 21c).
Mastery of advanced PL/SQL concepts including collections, bulk binds (FORALL, BULK COLLECT), ref cursors, and analytical functions.
Proven track record of resolving database bottlenecks, optimizing indexes, partitioning tables, and rewriting inefficient queries.
Strong understanding of database internals, locking mechanisms, concurrency, and session management.
Proficiency with database management tools such as Oracle SQL Developer, PL/SQL Developer, or Toad.
Must currently possess valid and unrestricted U.S. work authorization to be considered for this role. Individuals with temporary visas including, but not limited to, F‑1 (OPT, CPT, STEM), H‑1B, H‑2, or TN, or any candidate requiring sponsorship, now or in the future, will not be considered.

Nice To Haves

Familiarity with core Java development and modern enterprise frameworks.
Experience or exposure to Spring Boot, Spring Data, and dependency injection patterns.
Understanding of DDD principles (aggregates, bounded contexts, domain events) to help bridge application design with data models.
Knowledge of Hibernate or JPA, specifically regarding how application queries translate to the database layer.

Responsibilities

Design, write, and maintain robust, high-performance Oracle PL/SQL stored procedures, packages, functions, and triggers.
Architect and implement complex application business logic directly within the database layer for data integrity and speed.
Diagnose, troubleshoot, and optimize slow-running SQL queries, execution plans, and PL/SQL blocks using tools like TKPROF, EXPLAIN PLAN, and AWR reports.
Collaborate with software engineering teams to design efficient relational database schemas, tables, views, and indexes.
Partner closely with backend developers to align database-level business logic with application-level APIs and services.
Review database code generated by application developers to ensure adherence to performance standards and best practices.
