WALTER: Senior Software Engineer

Senior Software Engineers at Stamped are hands-on builders responsible for designing, developing, and delivering high-quality software that powers our products. This role combines technical depth with product intuition — engineers are expected to think like product partners, not just implementers.

They work closely with Product and the Director of Engineering to rapidly prototype, validate, and scale solutions that drive measurable user value. Senior Engineers bring curiosity, empathy, and a bias for action, leveraging AI tools and modern practices to deliver with speed, reliability, and craftsmanship.

This role has a strong emphasis on user-facing development — building intuitive, performant interfaces and components that merchants interact with daily. While full-stack capability is valued, you'll spend significant time on front-end architecture, UI implementation, and ensuring excellent user experiences across our product suite.

Our current systems include a large .NET/C# foundation on the backend, so familiarity with these technologies is helpful for full-stack collaboration, but your primary focus will be o modern front-end development and the user experience layer.

This group sits at the center of Stamped's shift toward an AI-native, iterative engineering culture — emphasizing autonomy, accountability, and shared ownership across the team.

Responsibilities

• Product Engineering: Design, build, test, and ship user-facing features with a focus on polish, performance, and usability.
• Front-End Development: Build and maintain responsive, accessible UI components and interfaces using modern frameworks and tooling.
• Prototyping & Validation: Rapidly prototype new user experiences to validate value before scaling.
• AI-Enabled Development: Use AI tools (e.g., Copilot, Claude, or similar) to accelerate development, reduce repetitive work, and improve code quality.
• Technical Judgment: Participate in front-end architecture decisions, component design patterns, and client-side performance optimization. Contribute to discussions on full-stack integration and API design.
• Execution & Ownership: Deliver against roadmap commitments with a focus on quality, maintainability, and iteration — especially on user-facing surfaces.
• Collaboration: Partner closely with Product and the Director of Engineering to align technical work with customer and business needs. Work alongside designers to ensure high-fidelity implementation of user experiences.
• Knowledge Sharing: Document, mentor, and contribute to a culture of learning and openness.
• Continuous Improvement: Stay curious and experimental with new tools, frameworks, and AI workflows that can improve speed, quality, or developer experience.

• 5+ years of professional software engineering experience, with significant time spent on front-end or full-stack development
• Strong proficiency with modern JavaScript/TypeScript and front-end framework (React, Vue, or similar) — experience building scalable, maintainable component architectures
• Experience with responsive design, accessibility standards, and client-side performance optimization
• Familiarity with backend technologies and APIs — experience with C#/.NET, Node.js, Python, or similar is a plus for full-stack collaboration
• Experience with cloud infrastructure (AWS preferred)
• Demonstrated use of AI tools or automation in the development workflow
• Product mindset: comfort wi
