Blitzy is a Cambridge, MA based AI software development platform on a mission to revolutionize the software development life cycle by autonomously building custom software to unlock the next industrial revolution. We're transforming how enterprises build software, turning enterprise requirements into production-ready code with an agentic software development platform that can autonomously execute 80% of the quantum of software development work. We're backed by multiple tier 1 investors, and have proven success as founders of previous start-ups.
About the Role
We're looking for a Senior Back-End Engineer to take real ownership across our stack. You'll work directly alongside our CTO on current product and future development, and partner with the founding team to shape product, technology, and strategy. You'll help build not just our software, but our culture, our processes, and our engineering practices.
There are hard, interesting problems to solve here. We want someone who finds that genuinely exciting. If your colleagues describe you as curious, driven, kind, and creative — you'll fit right in.

Blitzy, the emerging leader in System 2 AI, enables development teams to transform six-month software projects into six-day turnarounds using Blitzy, an agentic platform that enables thousands of AI Agents to ‘think’ and cooperate for hours to bulk build software with precision. The platform builds everything AI can deliver in a precise manner, around 80% of any roadmap or new product, supplemented with a human engineering guide to complete the remaining 20% needed for production. With over 27 patents and counting, Blitzy is actively hiring PhDs and senior developers in Cambridge, MA who have a passion for building AI that leverages ‘System 2 Thinking’ to solve problems at inference.
Blitzy was co-founded by Brian Elliott, a serial entrepreneur, and Sid Pardeshi, an ex-NVIDIA software architect with 27 Generative AI patents to his name.
