We are seeking a Senior Full-Stack Engineer who can independently design, build, test, and operate complex capabilities across our web application, backend services, data integrations, and video creation platform. This is a hands-on individual-contributor role for an engineer who can take ownership of significant product capabilities from technical discovery through production deployment. The ideal candidate combines strong frontend and backend expertise with sound architectural judgment, product thinking, and the ability to raise the technical performance of the broader team. This person should be able to work from product requirements and design concepts, identify technical gaps and edge cases, propose an implementation approach, and deliver production-quality software with limited oversight.

Experience with video, audio, media processing, creative tooling, animation, rendering, or digital asset management.

Experience with browser-based motion graphics using React, JavaScript, CSS animations, Canvas, WebGL, or related technologies.

Experience with AI platforms, large language models, retrieval-augmented generation, prompt orchestration, or AI-generated media.

Experience building configurable enterprise platforms with permissions, approval workflows, auditability, and governance controls.

Experience with message queues, event buses, serverless services, or distributed job-processing systems.

Experience with infrastructure as code and production observability platforms.

Experience in a multi-tenant SaaS environment.

Experience improving or modernizing an established software platform while continuing to deliver new product capabilities.

Own a complex capability with limited technical supervision.

Make sound technical tradeoffs and clearly explain the reasoning behind them.

Identify missing requirements, edge cases, dependencies, and operational concerns.

Produce implementation plans that other engineers can execute.

Deliver maintainable solutions rather than narrowly solving the immediate ticket.

Debug issues that span multiple services or application layers.

Improve the quality and productivity of engineers around them.

Communicate risks early and propose practical alternatives.

Balance speed, quality, scalability, and technical debt.

Demonstrate accountability for the production behavior of the software they build.
