CodeSignal welcomes Chris Kibarian to its board of directors.

CodeSignal welcomes Chris Kibarian to its board of directors. SAN FRANCISCO, July 23, 2026 /PRNewswire/ - CodeSignal, the leading AI-native skills intelligence platform, today announced that Chris Kibarian has joined its board of directors. Kibarian brings deep experience across the human capital management space, from labor market intelligence to talent acquisition and workforce development. He currently serves as CEO of International SOS, a leader in health and security risk services. Before that, he spent years as CEO of Lightcast, a labor market intelligence platform used by enterprises, educators, and public institutions. Earlier in his career, he led digital ventures at Randstad, overseeing platforms including Monster and RiseSmart. "Most companies are still measuring performance the same way they did a decade ago, even as the skills that matter keep shifting," said Kibarian. "Without a rigorous way to measure and validate what people can do, everything else - how you hire, develop, and retain people - is guesswork. CodeSignal understood from day one that skills assessments have to be the foundation." "Chris has spent much of his career making sense of how skills and labor markets move," said Tigran Sloyan, CEO and co-founder of CodeSignal. "That perspective is exactly what we need right now as we build new ways to help leaders re-evaluate, measure, and grow the in-demand skills of their teams in the AI era." Kibarian's appointment reflects CodeSignal's continued growth across enterprise hiring and workforce development, with customers spanning industries from tech and financial services to retail, healthcare, and more.

CodeSignal expands AI literacy assessments to measure workforce AI skills across business and technical roles

CodeSignal has expanded its AI literacy assessment library to help organisations measure workforce AI capabilities across business and technical roles. The AI-native skills intelligence platform offers assessments spanning sales, finance, product design, and engineering through realistic workplace scenarios. The assessments evaluate how employees apply AI tools to actual job tasks, rather than testing theoretical knowledge. They measure applied fluency, appropriate tool selection, critical evaluation of AI outputs, and recognising when human judgment is required instead of AI. Nearly two-thirds of global businesses have already delivered AI training to employees, whilst jobs requiring AI skills are growing nearly eight times faster than the overall market. CodeSignal's assessments are validated by industrial-organisational psychologists and audited for bias. The company's platform is used by Capital One, Meta, and Dropbox, with millions of skills assessments completed.

CodeSignal launches agentic coding assessments as 91% of engineers now use AI tools

CodeSignal has launched agentic coding assessments, designed to evaluate engineers' ability to work with AI coding tools. The move reflects a significant shift in software development, according to a March 2026 survey of 450 US software engineers. The survey found that 91% of engineers now use agentic AI coding tools like Claude Code and Cursor in their work, whilst 75% have shipped production code partially or primarily AI-generated in the past six months. Additionally, 73% believe engineers who don't adopt these tools risk becoming less competitive. The new assessments require candidates to extract requirements, use agentic AI tools to build solutions, and explain their technical decisions. Over the past six months, tens of thousands of candidates have completed CodeSignal's AI-assisted coding assessments, with roughly one-third of customers adopting the format during 2025.
