Job description

Job Overview

We are seeking a Senior Full Stack Engineer II to join our Digital Innovations team and help bring our most beloved brands to digital channels. In this role, you will own user‑facing features end‑to‑end across frontend, GraphQL/APIs, services, and data, improving performance, reliability, security, and accessibility. You’ll lead technical design and delivery for complex cross‑stack initiatives, partnering with Product, UX, and Engineering to align on tradeoffs and execution, in a collaborative environment where mentoring and shared learning are part of everyday work. As a senior technical leader, you’ll set the bar through hands‑on building and reviews, drive consistent client/server architecture patterns, and mentor a team of engineers.

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

• Lead cross‑functional initiatives (Product + Design + Engineering) delivering user‑facing features end‑to‑end
• Define frontend standards for Vue 3/React with TypeScript, including component and build system APIs. Promote state and GraphQL data patterns, performance budgets, and accessibility aligned with WCAG.
• Design and evolve GraphQL schemas and APIs that match product workflows.
• Build and ship backend changes in C#/.NET and/or Node.js, and make data model changes in Postgres/MongoDB driven by real usage and frontend needs.
• Mentor a team of engineers via pairing and code/design reviews to drive adoption of domain standards.
• Participate in on‑call and incident response for your domain; drive root‑cause fixes and embed security‑by‑default in features and APIs.
• Guide engineers in using AI agents effectively: model effective agent workflows for software development, share patterns for instructing and validating agents, and help fellow engineers get up to speed.

What You’ll Bring

• 7+ years building and shipping web products across frontend and backend.
• Strong frontend experience with Vue 3 and/or React + TypeScript, including large-codebase maintainability and accessible UI development (WCAG‑aligned).
• Experience defining or evolving state management, component architecture, and design systems.
• Backend and data experience designing GraphQL/REST APIs and implementing services in C#/.NET and/or Node.js, with Postgres/SQL + MongoDB.
• Experience operating production services in AWS (deployments, debugging, scaling/observability basics).
• Proven track record to lead cross‑team execution through clear design docs, technical discussions, partner alignment, and mentoring.
• Hands‑on experience using AI agents for production delivery including validating and correcting AI-generated code.

What Sets You Apart

• Event‑driven patterns (queues/pub‑sub).
• Prior experience breaking down monolithic framework architectures, built using .NET and C#, into smaller distributed services.
• Experience working with both relational (e.g., SQL Server, MySQL, Postgres) and non‑relational databases (e.g., DynamoDB, MongoDB).
• Curiosity about or knowledge of Wizards brands (e.g., Magic: The Gathering).

Who We Are

We’re a team of creators, storytellers, and innovators united under the Hasbro family and home to beloved brands, AAA digital games studios and immersive experiences that spark imagination across generations. Together, we’re committed to a culture rooted in creativity, excellence, curiosity, and inclusion, and where every employee is empowered to think boldly, act with integrity, and spark joy for all.
