## Description

The team designs and integrates ground- and platform-based collection systems built on model-based systems engineering (MBSE), open architectures, and open standards This position is for a **Lead Cyber Software Engineer** position on Neptune Phoenix to lead a team of software engineers implementing **cloud-based, full-stack software applications** that incorporate advanced algorithms, decision support processing, and data fusion.
The Lead Software Engineer serves as the authority for software architecture and design, and owns responsibility to create, evolve, and maintain the architecture of the software to meet operational needs across the full stack (front-end, back-end, data, and cloud infrastructure).
The **cloud-native solution** will include: + Decision support system processing and orchestration + Algorithm development and integration (e.g., optimization, analytics, and automated reasoning) + Producing knowledge from **disparate data sources** and sensors via scalable data services and APIs + Implementation of user-facing components and services that expose these capabilities to operators and analytic users The position requires strong **full-stack software engineering** skills and solid understanding of modern cloud architectures.
Desired knowledge includes computer networking and optimization, modern software development environments, cloud integration, and virtualized/containerized computing environments such as Docker or VMware.
Experience developing solutions using SysML/UML is a plus. **What You'll Get to Do** + Lead a team building **cloud-based, full-stack mission applications** that directly impact national security + Own the **architecture and design** of advanced decision support systems and analytic services + Build and integrate **microservices, APIs, and data pipelines** that turn disparate data into actionable insight + Work with modern tech (cloud services, containers, CI/CD) in a **real-world, operational environment** **Essential function of the role is leading a team conducting:** + **Full-stack Software Engineering** , to include design, development, integration, testing, deployment, and operations of cloud-based mission applications and services + Design and implementation of **cloud-hosted microservices, APIs, and data pipelines** to support decision support and analytic workflows + Evaluation of commercial solutions as part of make/buy analyses, including
cloud services and COTS/GOTS components + Development of custom algorithms and analytic services for decision making and situational awareness + Integration of custom analytic tools and decision support capabilities into an overall system and enterprise architecture + Development of **data products and knowledge services** for automated and manual consumers of generated data (dashboards, UIs, external systems, and APIs) **Basic Qualifications for Sr.
