Senior Software Engineer - Rendering & Delivery, MediaOS

Job Description

We're seeking a Senior Staff Software Engineer to provide senior technical leadership for the design and implementation of Arc XP's next-generation rendering platform. This is a highly visible individual-contributor leadership role for an engineer who can operate at both the architectural and implementation levels. You'll partner with architects, engineering leaders, product managers, and senior engineers to translate Arc XP's Experience Composition strategy into scalable production systems.

You'll help lead technical direction across areas such as edge rendering and composition, render-on-update architectures, component and extension models, platform and compilation APIs, content delivery, performance, and AI-enabled experience creation. Just as importantly, you'll help define how we evolve from today's platform to that future state while continuing to reliably support customers operating at significant scale.

You want to help build the next generation of a large-scale rendering and digital experience platform. You're excited by difficult problems at the intersection of web rendering, distributed systems, edge computing, content delivery, and AI. You enjoy exploring where computation should happen: at build time, origin, edge, or client, and making those decisions based on performance, personalization, reliability, scalability, and cost.

You want to turn ambiguous product and architecture strategy into working production systems. You enjoy challenging existing architectures and evaluating emerging technologies when there is a better way forward. You lead through technical expertise and influence and enjoy helping other senior engineers succeed. You balance innovation with the realities of evolving a large production platform without disrupting existing customers. You want ownership from technical discovery and prototyping through implementation, rollout, observability, and production operations.

• Lead technical design and implementation of Arc XP's next-generation rendering and Experience Composition capabilities.
• Design edge-rendering and edge-composition architectures, including component-level and server-island patterns, and lead the shift from TTL-driven regeneration to event-driven render-on-update models.
• Design scalable platform, rendering, and compilation APIs, and evolve component and extension architectures that enable reuse and customization without unnecessary forks.
• Help design the platform capabilities and APIs that let AI systems and agents programmatically create, compose, and update pages, templates, and components.
• Define migration and interoperability strategies that evolve today's Rendering, Themes, and Page Builder capabilities toward the next-generation platform while maintaining customer continuity.
• Provide senior technical leadership across Rendering, Delivery, Themes, and Page Builder Editor, keeping decisions coherent across interconnected areas.
• Design, develop, and operate highly scalable services using Type Script, Node.js, React, Go, AWS, and modern edge technologies.
• Lead resolution of complex production and architectural issues, and drive improvements in reliability, observability, performance, security, and cost.
• Mentor engineers through architecture discussions, design reviews, and hands-on collaboration.
• Use AI-assisted engineering tools thoughtfully for prototyping, implementation, and troubleshooting, applying strong engineering judgment to generated output.

• 8+ years of experience designing, building, and operating highly scalable software systems.
• Significant experience providing technical leadership, setting technical direction, and designing architecture for complex initiatives spanning multiple systems or teams.
• Deep knowledge of modern web rendering architectures, distributed and event-driven systems, APIs, caching and content delivery, and cloud-native application design.
• Strong experience with JavaScript/Type Script and modern web frameworks such as React, Astro, Next.js, or comparable technologies.
• Experience designing and operating high-traffic systems where performance, scalability, availability, and reliability are critical.
• Demonstrated ability to translate ambiguous product and platform strategy into technical designs and executable engineering plans.
• Experience designing platform APIs, frameworks, or extensibility models.
• Experience leading architectural initiatives through hands-on implementation and production delivery.
• Experience mentoring engineers and influencing technical direction without formal management authority.
• A BA/BS in Computer Science, Engineering, or a related technical field, or equivalent practical experience, is preferred.

• Deep experience in modern rendering and content delivery architectures, including server-side rendering, static generation, dynamic rendering, hydration, caching and invalidation, and the…
