Principal Software Engineer

About this role

Insurance touches people during some of the most challenging moments in their lives. Hi Marley is on a mission to transform how the P&C industry communicates, making those moments faster, easier, and more empathetic for carriers and the customers they serve. We build AI-powered software that keeps everyone in the claims conversation informed and connected. If you believe insurance can combine operational excellence and automation with a human touch, we’d love to meet you.

We're looking for a Principal Software Engineer, a person trusted with our hardest, highest-leverage technical problems. This is a dual-mandate role: you are both a multiplier for the team who raises the ceiling for engineers across the org, and a high-leverage builder who still Ships.

You'll go wherever the most important work is, from complex re-architectures of existing systems, to building ambitious new capabilities, to strengthening the foundations the whole team builds on. A lot of that is AI right now: the agent-driven experiences at the core of what we build, in a regulated insurance environment where carrier trust and compliance shape every decision. Teamwork and shared enthusiasm are a core part of our culture, which is why this role involves joining us in the Boston office 2–3 days each week.

What You'll Do:

• Set technical direction across domains. Define the patterns and architecture for multiple systems, make high-stakes trade-off decisions, and communicate them clearly to engineers, product, and executives.

• Work at the right altitude. Move flexibly between embedding deeply with a single team when an initiative needs your hands and operating horizontally across teams to set direction and unblock, exercising judgment and advocating for what the moment calls for.

• Technically lead complex initiatives end
