Senior Software Engineer at Greylock Partners San Francisco, CA

Job Description Senior Software Engineer position at Greylock Partners, San Francisco, CA. Greylock has a proven track record of investing in groundbreaking consumer companies such as Discord, Facebook, Instagram, and TikTok (formerly Musical.ly). We're excited to support a new startup led by seasoned entrepreneurs who previously built and scaled a billion-dollar consumer company with over 10 million users. This role offers a unique opportunity to join a consumer-focused team as a founding engineer—an ideal position for someone who combines technical excellence, entrepreneurial drive, and adaptability. If you aspire to eventually start your own company but are still searching for the right idea, this role provides a front‑row seat to shape technology, culture, and long‑term success. We’re looking for a candidate with at least 5 years of industry experience, ideally in developing large‑scale back‑end systems. Although our product is early‑stage, it has gained significant traction, and we need someone passionate about scaling our back‑end infrastructure. The ideal candidate thrives in fast‑paced, entrepreneurial environments, has a strong track record, and is eager to help build and scale a product from the ground up. Since the company is currently in stealth, additional details will be provided to qualified candidates.
