Senior Software Engineer

Greylock has a history of creating and investing in groundbreaking consumer companies like Discord, Facebook, Instagram, and TikTok (formerly Musical.ly).

We’ve recently backed a fast-growing mission driven product in the self-directed health space. The app is gaining substantial traction as more people seek genuine control over their wellness routines, moving beyond the noise of trends and misinformation. The founding team brings deep experience from successful exits in social platforms, music tech, and health e-commerce. It’s a massive market, currently valued at 177 billion dollars and growing at a rate of 9 percent annually.

This role is a rare opportunity to join a consumer-focused team as an early engineer. The ideal person combines technical strength, entrepreneurial energy, and adaptability. If you hope to start your own company one day but are still searching for the right idea, this role offers a front row seat to shaping the product, culture, and long-term success of a growing startup.

We’re looking for someone with at least 5 years of industry experience who enjoys crafting user experiences, building core features, and helping maintain a strong design system. You should have a product mindset and value working in a lean, AI-accelerated environment. You’ll collaborate closely with product, design, and backend teams.

A few things you’ll work on:

• Develop new features and UI components using SvelteKit (Svelte 5) and Tailwind CSS
• Support our migration to Svelte 5 and adopt modern frontend best practices
• Build AI-powered experiences such as our chatbot, supplement stack analysis, and personalized health plans

Bonus if you’ve worked with Svelte before or are excited to dive into it.
