Job Summary
The Information Systems and Cyber Division (ISCD) integrates modern software technologies—including elastic compute clouds, containerization, microservices, real-time operating systems, and visualization frameworks—with expertise in cyber security, software architecture, software engineering, data science, artificial intelligence, process improvement, and software development to deliver resilient, high‑performance software systems for Intelligence Community, DoD, and civilian customers.
The Software Tools & Assurance Department advances modern software engineering and digital engineering practices to deliver responsive and reliable mission software, with a focus on cloud platforms, microservices, workflow automation, and system modernization.
Work Model
This is a full-time position based in El Segundo, CA.
What You’ll Be Doing
Providing software systems engineering skills to space, ground, and launch systems in the national security, civil, and commercial domains.
Designing and developing backend services and REST APIs that integrate with enterprise systems, cloud platforms, and data sources to deliver reliable, scalable solutions.
Building and maintaining data ingestion pipelines — including metadata extraction, content indexing, change detection, and automated job monitoring — that enable enterprise-wide search and data access.
Extending and enhancing workflow automation systems, including process definitions, business validation logic, audit logging, and notification services, to replace manual processes across the organization.
Identifying opportunities to adopt emerging technologies — including AI/ML and large language model applications — to solve existing organizational challenges and predict future needs.
Leveraging cloud platforms and modern tooling to replace brittle legacy systems with maintainable, automated solutions that reduce cross-system dependencies.
Collaborating with teams across the corporation to develop cross-domain solutions and engaging with customers to deliver software that addresses their most challenging problems.
What You Need to be Successful – Senior Member of Technical Staff – Software Architecture Engineering & Cloud Computing Architecture
Minimum Requirements:
Bachelor's degree in computer science, computer engineering, electrical engineering, or a related field.
4 or more years of experience with increasing responsibility in software engineering or software architecture.
Proven ability to manage multiple concurrent tasks and to quickly learn and adapt to new software technologies and languages.
Experience in software engineering, full lifecycle development, and advanced problem solving.
Experience in at least one of the following areas:
Modernizing legacy or multi-system pipelines into unified, maintainable, automated software applications
Designing and maintaining backend services and REST APIs using modern frameworks (e.g., Spring Boot) with integrations across enterprise services, workflow systems, and cloud environments
AI/ML applications, including large language models (LLM), retrieval-augmented generation (RAG), or NLP
Building or extending data ingestion pipelines — including large-scale content ingestion, metadata extraction, change detection, indexing, and automated job monitoring
Cloud and microservices architecture, including managed services for compute, storage, and monitoring
Experience integrating systems across on-prem, cloud, and hybrid environments, including Linux-based deployments and enterprise search ecosystems
Agile methodologies, DevOps, and CI/CD practices to deliver maintainable and reliable software solutions
Willingness to travel occasionally to other domestic work locations or customer sites.
This position requires the ability to obtain and maintain a security clearance, which is issued by the U.S. government. U.S. citizenship is required to obtain a security clearance.
How You Can Stand Out
It would be impressive if you have one or more of these:
Master’s degree from an accredited program in computer science, computer engineering, electrical engineering, or related field.
six or more years of industry experience developing and maintaining enterprise software systems, with a demonstrated track record of delivering production backend services.
In-depth knowledge and experience in two or more of the following areas, with the ability to independently lead associated tasks:
A track record of leading modernization efforts that consolidate multi-step manual processes, legacy scripts, or fragile data pipelines into reliable, automated applications — reducing operational burden, technical debt, and cross-system dependencies
Experience architecting or scaling enterprise data ingestion systems, including high-volume document or media ingestion, metadata extraction, indexing pipelines, or cross-platform content integration
AI/ML applications, including LLM-based tools, RAG architectures, or NLP
Backend service development using modern frameworks (e.g., Spring Boot), with REST API design, systems integration, and database interaction (relational and cloud-hosted)
Workflow automation platforms and BPM tooling (e.g., Camunda, BPMN process definitions), including audit instrumentation and notification services
Cloud platforms (AWS, Azure) for storage, compute, monitoring, and certificate management
Agile workflows, CI/CD pipelines (e.g., Jenkins), and rapid prototyping of internal software tools
Excellent written and verbal communication skills, with the ability to clearly convey complex technical information to a wide range of audiences.
Experience consolidating fragile, multi-step manual processes or legacy scripts into unified, automated software applications.
Demonstrated ability to bring industry knowledge of modern software practices to drive innovation within established teams.
