Principal Front-End Engineer [Growth]

3Play Media · Remote — US · $200,000 – $250,000 The Role We are looking for a Principal-level engineer to join our Growth team with significant front-end and platform experience. This role sits at the intersection of platform engineering, product craft, and modern marketing — you'd build and manage infrastructure for both our Remix product and our Astro marketing site, deliver features alongside the rest of the team, and help build the agentic development platform that lets the whole company — engineers, marketers, designers — ship more, faster, and with higher quality. You won't be inheriting a playbook. You'll be helping write one. You'd be a great fit if you believe the product is the brand, have good taste in design and dependencies, have already been pushing the frontier on AI-assisted development, and want to ensure we build a performant and accessible experience across all projects. What You'll Do Build up our agent tools and workflows — custom Claude skills, MCP servers, agent loops, and the developer-experience scaffolding around them — so every engineer is meaningfully faster, and so non-technical team members can safely ship content changes and agent-coded pages using Claude Code. Do real product work in our Remix and Astro applications alongside the rest of the Growth team — building product pages, managing our design systems, and improving marketing page layouts. D
