Senior Software Engineer, AI Product

New Yesterday

At Magical, we empower organizations to automate the complex, manual workflows that are essential to their operations. We're building a brand new product, and this is your chance to join as a founding engineer. In just a few months, we've already hit product-market fit and closed six-figure deals with a clear path to much bigger contracts. We're not starting from scratch either: our existing product has generated millions in revenue. Now, we're evolving that user base toward our agentic future while consistently bringing in new customers.
You'll work in a small, nimble team tackling challenging, ambiguous problems at the cutting edge of technology and learn something new every day. We believe the effort and raw hours you put in directly shapes the outcome. Speed matters, and we move with focus and intent.
