Overview

Peraton is seeking a high-impact Senior Software Engineer (SWE) with proven experience designing, building, and sustaining front-end and full-stack capabilities for RF SIGINT collection, processing, and visualization systems. This is a senior technical contributor role supporting critical national-level operations. The ideal candidate brings deep technical mastery, understands mission operations, and can lead teams in delivering secure, high-reliability software for complex signal intelligence environments.

You will architect, develop, modernize, and sustain advanced UI/UX components and support services for SIGINT operations, integrating real-time RF data flows, analytics, and mission tools into intuitive operational interfaces. This role directly impacts operators and analysts working in time-sensitive mission environments.

Key Responsibilities

Mission-Focused Software Engineering

• Analyze, decompose, and translate mission/user requirements into scalable software architecture and performance-driven designs.
• Design and implement new UI features, visualizations, dashboards, and mission workflows supporting RF SIGINT operations.
• Integrate front-end applications with back-end services, signal processing pipelines, data repositories, and real-time mission environments.

System Integration & Optimization

• Integrate new and legacy software into diverse Linux, UNIX, and Windows operational baselines.
• Develop and optimize algorithms and interfaces supporting signal processing, system performance, and time-sensitive mission demands.
• Implement complex database and repository interfaces, ensuring high throughput and low latency.

Full Software Lifecycle Execution

• Develop, test, debug, and deploy mission-critical software under strict performance, timing, and resource constraints.
• Modify and modernize legacy software to adapt to new hardware, operating environments, and mission requirements.
• Create, review, and maintain technical documentation, system design artifacts, user guides, and interface specifications.

Leadership & Technical Ownership

• Lead or serve as senior technical advisor for multiple development teams, ensuring alignment with mission goals and software engineering best practices.
• Select or influence the software development processes (Agile, SAFe, Kanban, etc.) used for major efforts.
• Ensure quality control of all team deliverables and enforce rigorous engineering standards.
• Work closely with systems engineers, hardware engineers, and mission stakeholders to refine architectures and ensure operational readiness.

Operational Interface & Mission Support

• Support installation, configuration, and validation of deployed systems.
• Monitor mission system functionality to ensure operational performance metrics are met.
• Recommend emerging technologies, frameworks, and tools that enhance mission capabilities.
