Signal processing software and hardware for spectrum analysis and signals intelligence
3dB Labs builds signal processing and analysis platforms combining proprietary Sceptre software with custom hardware, serving defense and intelligence sectors. The tech stack mixes low-level compute (C++, CUDA, x86) with modern web frontends (React, Node.js), and active hiring is concentrated in engineering (11 roles) with mid-to-senior seniority — a pattern typical of companies scaling technical delivery on classified or high-assurance contracts. Current project focus on documentation pipelines, infrastructure scaling, and customer onboarding suggests internal operational friction as the business grows.
3dB Labs is a software and hardware engineering company founded in 2004 and based in West Chester, Ohio. The company specializes in signal processing, spectrum analysis, and signals intelligence solutions, anchored by its proprietary Sceptre software platform. Their customer base appears to be U.S. government and defense organizations requiring real-time analysis capabilities in challenging RF environments. With 51–200 employees, 3dB operates as a private, vertically integrated shop — design, manufacturing, and field support — and is actively hiring across engineering and support functions to scale both lab capacity and production delivery.
Core compute: C++, Python, CUDA, Linux, x86. Frontend: React, Node.js, HTML5, CSS. Proprietary: Sceptre (signal processing). Hardware tools: SolidWorks. Infrastructure: VMware ESXi, Windows. Collaboration: GitLab, Mattermost, Jira.
Active projects: converting legacy Word documentation to markdown, establishing release and update pipelines, scaling lab and production infrastructure, VM migration, customer adoption programs, and technical onboarding.
