Cloud Software Engineer 3 (TS/SCI with Full Scope Polygraph)

Location

Annapolis Junction, MD (on-site)

Type: Full-time, permanent

Clearance: Active TS/SCI with current polygraph required

Salary: $199,000 – $238,000, depending on experience

The role

You’ll build, maintain and improve large, complex big-data cloud systems for a mission-focused federal program. You’ll work across the full back end, covering data processing, analytics and indexing, as a hands-on engineer and technical expert in Hadoop, distributed computing and information retrieval.

You’ll work on your own and as part of a team, and help shape system design decisions from system level down to individual software components.

What you’ll do

• Design, develop and test cloud-based information retrieval and big-data processing systems, mainly in Java.
• Build and manage complex MapReduce analytics workflows.
• Write code that works with distributed file systems, BigTable-style data stores and distributed coordination frameworks.
• Architect solutions for processing and retrieving very large volumes of data efficiently.
• Debug and tune distributed computing frameworks, and install and manage multi-node cloud environments.
• Review and test software against design requirements, document results and resolve software problem reports.
• Advise on hardware/software trade-offs, software reuse, and when to use commercial or government off-the-shelf products (COTS/GOTS) instead of building new.
• Lead one or more development tasks: delegate work, monitor performance and ensure quality control of all software.
• Act as the team’s subject matter expert on Hadoop and cloud computing.

Recommend new technologies, process improvements and documentation standards.
