Senior Full-Stack Software Engineer

At Atonom.ai, we are defining the Autonomous Era by building the world’s first true "Cloud Employees", intelligent AI agents capable of executing complex work across Sales, Marketing, Support, and HR.

We believe that growth should be limited only by ambition, not headcount.

By moving beyond simple automation to genuine autonomy, we empower businesses to scale their workforce instantly and efficiently.

Join us as we build the infrastructure for the next generation of work, where human creativity pairs with limitless machine execution to achieve the impossible.

• Collaborate with AI and Product teams to turn business problems into robust software that integrates prompts, automations, and guardrails.
• Improve developer experience through testing strategies, build pipelines, documentation, and operational runbooks.
• Mentor early and mid-career engineers while raising the bar on code quality and engineering excellence.
• Partner with Customer Success during go-lives to ensure smooth deployments and capture learnings.
