Senior Frontend Engineer

Senior Frontend Engineer Our client is a Latvian-born supplements-on-demand platform built on a print-on-demand model and operating in the US market. Founded in 2021, the company is preparing for a Series A funding round (targeting ~$10M, September 2026) and is scaling rapidly toward a goal of growing revenue from $10M to $250M. With a lean team of 56 across Latvia, they are building the technology foundation to support that growth — and they need a senior frontend engineer to bring structure to a fast-moving, design-heavy engineering culture. About the role The core mission here is leading the platform's migration from Webflow to Astro and Sanity CMS, while building a robust design system that works as a standalone package — usable by platform engineers, by designers building landing pages, and by anyone else creating presentations. The groundwork exists; your job is to make it production-grade. You will work in a 7-person IT team (CTO, engineers, 1 DevOps) where radical autonomy and bottom-up ownership are the default. A key part of this role is bridging the gap between vibe-coding designers — who work with AI tools and move fast — and the engineering team, without slowing either side down.
