Principal Software Engineer

About the role

We take play seriously. We’re looking for curious adventurers ready to find their party, fueled by imagination and drive to build what’s never been built before. At Hasbro and Wizards of the Coast, you’ll collaborate with passionate teams to reimagine our iconic brands and create experiences that spark joy, connection, and community through the magic of play. This is your chance to shape legendary play that lasts a lifetime.

Job Overview

The Digital Innovations Team (DigIT) is changing how Wizards develops, delivers, and manages the digital systems behind our games — for players, retailers, and the studios that develop our worlds. We are seeking a Principal Software Engineer who can guide product ideas through every stage with agentic AI — from defining the problem with business partners, to developing the system, to deploying it in production, and then improving it based on actual data.

This role is hands-on. We need a creator who builds and ships with agentic AI. Someone who has directly shipped product to production by agentic AI, can provide the code and performance assessments, and can discuss in detail what was successful, what did not succeed, and what they would do differently. If you have built and shipped with agentic AI and want to keep building, we'd love to hear from you.

You will be responsible for the technical direction of an initiative and the related product surface area, direct tech direction and product direction with or without Product Manager (PM) support. You are answerable for what the team delivers, how quickly it adapts, and the business outcomes that result.

You will build products with agentic AI as your default approach, using the harness engineering and guardrails the team has developed and helping evolve them alongside peers. Your primary focus is shipping product, and you bring production-based judgment about evaluations, guardrails, cost, latency, determinism, and delivering AI products responsibly at scale.

Location and Work Arrangement

This role is based at our Renton, Washington office and follows a hybrid schedule designed to support in-person collaboration. Employees are expected to work onsite on Tuesdays, Wednesdays, and Thursdays, with the flexibility to work remotely or onsite on Mondays and Fridays.

What You'll Do

- Guide product concepts through the entire process with agentic AI. Starting from outlining the problem alongside product and business collaborators, moving to prototype development, to a data-informed launch, and then refining based on actual usage data. You are responsible for the full journey, not only a segment of it.

- Build, hands-on with agentic AI. Keep close to the code. Deliver production-quality agent systems, analyses, prompts, and supporting services on your own. Set the standard for agentic AI development through delivered, working results rather than discussion.

- Direct the build process through data-driven insights. Lead product ideas as testable hypotheses. Start tracking early and confirm success criteria before coding begins, with or without PM support. Base decisions on actual data concerning what to prioritize, change, or remove. Ensure the feedback loop is as short as feasible.
