About the role
Founding Engineer — Orange Slice (YC)
About Orange Slice
Orange Slice helps revenue teams prospect, enrich, qualify, and automate GTM work with AI. Customers use it to turn messy intent and company context into actionable lists, enriched records, and workflows—from firmographics and contact verification to web research, social signals, and outreach drafting. The product spans a polished web experience (including spreadsheet-like execution and an AI agent) and tooling for builders who want the same capabilities in code or in Claude Code via a single install path.
We sit at the intersection of B2B data, LLMs, and workflow automation—where reliability, cost control, and great UX matter as much as model quality.
The role
We’re hiring a Founding Engineer to own major slices of the product and infrastructure alongside the founders. This is a high-ownership, high-trust role: you’ll ship user-facing features, harden core systems, and help define how we scale—not just close tickets.
You might work on:
-
Core product: Next.js App Router surfaces (dashboard research tools, spreadsheet workflows, agent/chat UX), performance, and end-to-end flows from signup to paid usage.
-
Data + AI execution: orchestrating long-running enrichment and research jobs, streaming UX, provider integrations, and guardrails (cost, retries, observability).
