Software Senior Principal Engineer / Autonomous AI Software Engineering

Software Senior Principal Engineer – Autonomous AI Software EngineeringSoftware engineering is being reshaped by autonomous AI agents that can plan, write, test, and review code with increasing independence. Our team works at the forefront of that shift, bringing agent-driven autonomy into the software development lifecycle so that engineers set direction and make key decisions while agents handle execution.Because the agent landscape evolves rapidly, we stay hands-on: exploring promising approaches, validating them through rigorous experimentation on real engineering workloads, and turning successful outcomes into enterprise-grade software development practices. We are a small, AI-native team operating with startup agility—emphasizing high autonomy, rapid iteration, and seamless human-AI collaboration.Join us to do the best work of your career and make a profound impact as a Software Senior Principal Engineer on our AI Governance Engineering team in Hopkinton, Massachusetts. This is an onsite role.What You'll AchieveYou will serve as the technical leader and architect for autonomous AI across our software development lifecycle. You will define the target architecture for agent-driven engineering, lead objective evaluations of commercial, open-source, and in-house technologies, and translate proof-of-concept results into actionable technical strategies for executive leadership.This is a hands-on architecture role: you will write code, build critical prototypes and integrations directly, and guide engineering teams by technical example from pilot stages to enterprise-scale deployment.
