Jobs at STR

Design, develop, and deploy advanced software systems using systems engineering and MBSE. Derive and document requirements from incomplete software implementations, create SysML models in Cameo, perform capability gap analyses, and maintain traceability across the systems lifecycle. Collaborate with domain experts and software teams on mission planning, ISR management, and decision-support applications. The role requires an active DoD Top Secret clearance with SCI eligibility and supports a hybrid work environment.

Lead and scale a classified test and evaluation organization, including specialized R&D teams, customer relationships, proposal capture, multi-million-dollar P&L management, program execution, security compliance, and employee development. The role requires extensive classified testing experience, technical credibility in an advanced engineering domain, successful defense contract capture, experience across Western Test Ranges, an active Top Secret clearance, and DoD test-school training.

Lead and direct multidisciplinary teams to research, develop, test, integrate, and demonstrate advanced signal processing, optimization, and machine learning algorithms for radar, electronic warfare, and sensor systems. Oversee modeling/simulation, algorithm T&E, customer engagement, and technical briefings for defense and intelligence applications.

Lead technical teams in developing and demonstrating novel signal processing and machine learning algorithms for electronic warfare and sensor applications, ensuring performance and integration into RF-based systems.

Lead full life‑cycle federal contract management for DoD and Intelligence Community programs: develop proposal and negotiation strategy, ensure FAR/DFARS and export control compliance, advise senior leadership, maintain contract records, negotiate agreements, drive process improvements, mentor junior staff, and collaborate cross‑functionally while using AI tools to improve efficiency.

The Senior Software Engineer will lead technical discussions, develop innovative software solutions, mentor junior engineers, and enhance data communications systems. They require 5+ years of experience and programming skills in Python, C, and C++.

Lead development of real-time C/C++ software for RF sensor systems, including CUDA-accelerated signal processing, embedded and distributed computing, multi-core CPU/GPU optimization, open architecture compliance, testing, documentation, technical reviews, customer briefings, proposal support, and cross-functional integration. The role requires Secret clearance eligibility, substantial software engineering experience, and approximately 20% travel for integration and field demonstrations.

Lead a 10+ person accounting team to manage financial accounting, technical and cost accounting, tax, SOX controls, monthly/quarterly close, POC/EAC for government contracts, audit readiness, and build SEC-ready reporting.

Lead small multidisciplinary teams to design, integrate, and test RF and sensing systems (radar, EW, signal processing). Define requirements, perform trade studies, develop test plans, conduct over-the-air demonstrations, validate performance via simulation and measurement, and prepare design and test documentation while coordinating with mechanical, firmware, software, and systems engineers.

Manage end-to-end federal procurement lifecycle for defense and government programs in compliance with FAR/DFARS. Lead supplier qualification, source selection, negotiations, and vendor relationships. Use ERP and purchasing systems, apply export control knowledge, mentor staff, drive process improvements, and leverage AI-enabled tools to improve efficiency, cost, schedule, and performance.

Lead multidisciplinary teams to design, develop, test, and analyze biotechnology solutions for health and national security; perform experimental and statistical characterization; drive technical marketing and proposal development; serve as primary technical contact for customers and partners.

Design, simulate, integrate, and test RF hardware systems for space-based sensing and electronic warfare. Perform trade studies, bench/unit tests, over-the-air demonstrations, system integration and verification, collaborate with signal processing teams, and produce specifications, test plans, and performance reports.

Lead development and application of advanced signal processing, detection, classification, and machine learning algorithms for radar and RF sensing/electronic warfare. Engage customers, lead multidisciplinary teams, translate capabilities into requirements, develop prototypes and demonstrations, and support business development and proposals.

Lead design and implement real-time digital signal processing software for multi-function radar/EW systems. Architect embedded solutions, perform simulation and field testing, optimize performance, produce design/test documentation, and lead/mentor cross-functional teams through development and deployment.

As a Senior Data Scientist, you will develop technologies for signals exploitation, perform data analysis, and implement algorithms while collaborating with project teams.

Seeking a Senior Systems Integration and Test Engineer to oversee integration/test of advanced RF systems, working with teams to ensure software/hardware functionality, developing test plans, and providing test metrics with a focus on DoD systems.

The Senior IT Support Specialist resolves complex hardware, software, and network issues, manages IT resources, and provides exceptional support to users.

Researches, develops, evaluates, and integrates AI and machine learning models for national security applications. Analyzes multimodal datasets, including text, imagery, geospatial, time series, and social media data, to identify patterns and generate intelligence insights. Collaborates with researchers, engineers, domain experts, customers, and end users; communicates findings, defines requirements, responds to feedback, and mentors teammates. Work primarily occurs onsite in Woburn, Massachusetts, or Arlington, Virginia.

The Senior DevOps Engineer will establish CI/CD infrastructure for embedded systems, manage deployment environments, and support software development teams with automation and testing frameworks.

The Senior RF Hardware Engineer will design and implement RF hardware systems, collaborate on multi-disciplinary teams, and support testing and deployment of advanced RF systems.
