Senior Software Engineer

Founded in 2024, AZX delivers AI transformation for critical industries, such as energy, real estate, and infrastructure. We believe success means removing barriers between ideation and execution, prioritizing code over PowerPoint, and focusing on challenging client problems. As a result, our strategy, execution, and acceleration solutions apply start-up principles that challenge conventional thinking, implement quickly, and deliver results.

We don’t build bloated slide decks—we build systems that matter. We’re profitable, growing, and committed to solving meaningful problems through humility, innovation, and excellence.
