Founding Engineer

AI has made it almost free to send cold emails that sound personal, and inboxes are drowning in them. Companies spend money on ads, data, and outreach tools to get someone's attention; we think more of that money should go to the person they want to reach. Instant Expert lets you pay customers, candidates, and experts for a call or reply, with payment only when they respond. Our ambition is to make paying for someone's time a normal part of doing business.

You'll build across the product, with an initial focus on the supply side: finding the right people, reaching them, and turning requests into completed calls and replies.

• Help customers find people they couldn't reach before by improving search and enrichment across Exa, Crustdata, and Apollo.

• Find more accurate contact details at lower cost through providers like Findymail, ContactOut, and OpenMart.

• Scale email sending across Gmail API, Resend, and SMTP, improving deliverability and reliability as volume grows.

• Automate research, follow-ups, reply handling, and booking so more requests succeed with less manual work.

You're a strong, product-minded engineer who's owned consequential systems in production, with depth in large-scale email, people-data integrations, or workflow automation. You can move from API and data problems to a polished customer experience. Experience as a founder or very early startup hire is a strong plus.

You're ambitious, resourceful, and fast. You want broad ownership, make good calls with incomplete information, and follow through until customers see the improvement.
