We’re looking for a sharp, hyper-organized Executive Assistant to work directly with Keshav. Keshav is juggling multiple high-velocity projects and needs a proactive, sharp Executive Assistant to help him stay focused, organized, and operating at his best. This role sits at the heart of everything — part Chief of Staff, part life ops, part confidant. What you’ll be doing: Own and manage Keshav’s calendar — protect his time like a bodyguard. Prioritize incoming requests, emails, and to-dos on his behalf. Coordinate with designers, engineers, and other high-leverage collaborators. Handle logistics: travel, events, and personal errands. Research, summarize, and present information to help him make fast, informed decisions. Act as a force multiplier — anticipate what’s needed before he even asks. You might be a good fit if you: Are incredibly detail-oriented, organized, and obsessed with efficiency. Have excellent communication and writing skills. Know how to move fast without breaking things (and can clean up when needed). Are curious about the startup/design/tech world and hungry to learn more. Are discreet, trustworthy, and comfortable handling sensitive information. Have 1–3 years of relevant experience (though mindset > resume). Bonus points if you: Have worked directly with founders, execs, or early-stage teams before. Have exposure to design, product, or tech — even informally. Why this is cool: You’ll get a front-row seat into the world of startups, design, and tech. You’ll work directly with someone who values autonomy and craft. You’ll never be bored — this role evolves as fast as Keshav’s projects. It could be a springboard into ops, product, or creative roles down the line.

Read Before Applying Not a Fit If: You’re optimizing for work–life balance above all else right now. You treat engineering as just ticking boxes rather than mastering a craft. You spend a week just trying to figure out what’s next instead of diving in quickly. You’re not comfortable working at a fast pace, including sorting out bugs right away, even if that means working seven days a week sometimes. You're a Fit If: You have 3–5 years of hands-on product engineering experience. You’re comfortable with our stack: React Native for front end, Node.js for back end, and Swift for iOS. You thrive on shipping quickly, iterating often, and handling issues as they come, no matter the day of the week. What You’ll Do Build and ship robust, motion-rich interfaces using React Native. Work closely with product, engineering, and AI teams. Own the end-to-end flow of features, from concept to deployment, and fix issues promptly. Must-Haves 3–5 years in leading consumer or web app development. A portfolio or track record you’re proud of. A relentless drive to keep leveling up your engineering game. Sound like you? Apply here →
