John Pennington is a seasoned technology executive with 11 years in senior engineering leadership and two decades of hands-on product and architecture experience, now leading Amplifier Security as Head of Engineering. He has a strong track record scaling SaaS businesses through technical rigor, M&A diligence and post-acquisition integration, having run global R&D organizations and P&L-backed teams at Bullhorn and TRUX. John blends product-focused innovation—creating AI research groups, Data-as-a-Service initiatives and platform re‑architectures—with operational discipline in DevOps, FinOps and security maturity programs. He mentors and builds high-performing teams across distributed sites, turning early prototypes into MVPs and multi-million-dollar ARR product lines. A designer by training, he brings a practiced eye for UX and system composability, evidenced by earlier work on dynamic application composition and rule engines that materially increased product value through acquisition. Based in Missouri, he combines pragmatism and empathy to drive user-focused, automatable solutions in complex enterprise environments.
