    Job Description

    Large aerospace and defense company is looking to hire a Junior Systems / Support Engineer for their Pasadena, CA location to work on exciting projects with their space research customer. The successful candidate will be part of a larger team supporting Ground Data System Operations at various levels and will be an integral part of the team’s success.

    This position is ideal for an energetic and savvy engineer who loves technology and problem solving, but also has teamwork, communication and people skills as part of their DNA. This is a position for someone who is customer-focused, reacts well to changes, can work independently or with teams and is able to multi-task on multiple products and projects.

    Responsibilities include, but are not limited to: 

    • Starting, monitoring, and debugging the operations of the OPERA SDS data production cluster, which will execute tens of thousands of jobs per day to generate hundreds of thousands or products daily, delivered to the archives.
    • Analyzing the performance of the cluster, identifying bottlenecks, propose possible solutions.
    • Writing and executing scripts to execute data accountability, identifying gaps in data production, and product distribution to verify latency requirements.
    • Testing new software releases on development and I&T cloud environments before they are deployed into production.
    • Executing data processing requests for other OPERA teams, such as ADT (Algorithm Development Team) and PST (Project Science Team), to enable validation at scale of the science algorithms before the start of operations.
    • Identifying potential issues and problems before they arise, determining the root cause and developing solutions.
    • Developing scripts to automate tasks when possible.
    • The candidate will participate in the project’s weekly meetings for task assignment, prioritization, progress report, and team collaboration, and work with the rest of the team to meet the project deadlines and milestones.
