Database Application Developer

Position Summary 

OPEX Corporation is currently looking for a junior or mid-level software developer to join our Cortex database team. Cortex equipment management and order fulfillment software controls OPEX's robotic automation equipment and acts as the brains of a fulfillment operation. Database interaction plays a central role in this application suite. Proficiency in this area is a core requirement for this role. This position will be responsible for designing new schemas and PL/PGSQL functions to ensure data consistency while allowing for deeply customizable business logic to meet each customer's unique requirements. We subscribe to the philosophy of "smart database, thin clients" which places a significant portion of the application logic in the database. This is a coding position, not a DBA role. The candidate will require strong software development skills to pair with their database knowledge.  This position is based in Moorestown, NJ.

The Company

OPEX is a global leader in robotic warehouse automation system design, development, manufacturing, production, installation, and service. Our warehouse automation systems incorporate the latest mechanical, electrical, robotic and software technologies. We specialize in next generation goods-to-person (G2P), sortation, and warehouse control software & consulting.  OPEX's customers are among the largest e-commerce, consumer retail, cosmetic, pharmaceutical, and package delivery companies in the world. We offer a vibrant, collaborative, and entrepreneurial work environment with team members who care about producing quality products.

Responsibilities

This role requires a team-oriented software developer who is a hands-on coder, but also able to provide a fresh perspective and new ideas to a growing team. This person will be expected to:

  • Develop well-crafted and thoroughly tested software. Our customers have unique demands which require creative testing solutions.
  • Initiate and participate in code-reviews as reviewer and reviewee.
  • Analyze, plan, and break down projects into smaller tasks. 
  • Hold themselves and the entire team accountable to the highest standards.  Code is merged with no warnings and all tests passing.
  • Ensure team is using contemporary software development methods and tools.
  • Empower individuals and the team to be successful.
  • Embrace culture of continuous learning and improvement. Take what you learn and challenge status quo.
  • Participate in agile ceremonies as a member of the database scrum team.
  • Improve quality and efficiency, in part by expanding use of automated testing.
  • Deliver large, complex projects with quality.
  • Coordinate multiple high priority tasks.

Skills & Qualifications:

  • Bachelor's degree in computer engineering, computer science, related field, or relevant experience. 
  • Technical/Engineering experience in a software development organization 0-10 yrs. 
  • Experience developing new products is strongly preferred.
  • Experience developing, coding, and interfacing with relational databases.
  • PostgreSQL and PL/PGSQL preferred. Familiarity with other database environments is welcome as well.
  • Domain knowledge in Material Handling, Warehouse Automation or Industrial segment is strongly preferred.
  • Exceptional listening, verbal, presentation, interpersonal, and written communication skills. 
  • Ability to travel when necessary (typically less than 20%).

Salary range of $70,000 - $120,000 based on experience.
