## **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).
* **Billing and usage**: subscriptions, credits/ledger, org vs. personal accounts—systems that must be correct under load and easy to reason about.
* **Platform**: Supabase-backed Postgres (including RLS-aware patterns), background jobs (e.g. Inngest), and services that fan out heavy work reliably.\
\
**30 days**\
You’ll **ship improvements to our multi-step agentic research workflow** (tool orchestration, reliability, and UX at the boundary between LLM reasoning and real data execution) and **take primary ownership of our Inngest pipeline**—event design, step boundaries, retries, observability hooks, and safe rollout patterns—working closely with whoever owns the batch service and API routes today.
**60 days**\
You’ll **own a measurable slice of production reliability**: cut a class of failures (timeouts, stuck runs, duplicate side effects, or stream resume issues), and **instrument it** so regressions are obvious (logs/traces/metrics—bonus if you’ve used LLM observability tools).
**90 days**\
You’ll **lead a multi-sprint initiative** that compounds—examples: faster/cheaper agent execution, a major schema/migration win, a billing/credits hardening project, or a step-change in streaming UX quality under load—documented with **before/after metrics** from production.
### **What we’re looking for**
* **Strong TypeScript** and comfort owning features **full-stack** (React/Next patterns, server routes, database design).
* **Bias to ship**: you break work into milestones, default to simple designs, and iterate with real users.
* **Systems thinking**: you care about idempotency, failure modes, and operational clarity—not only happy paths.
* **Product sense**: you ask _who is this for and what must be true for them to trust it?_ especially around data quality and AI outputs.
* **Bonus** (not required): experience with **Postgres at scale**, **Stripe billing**, **queue/workflow systems**, **LLM app patterns**, or **B2B data / GTM tools**.
### **Stack (for transparency)**
Next.js (App Router), React, TypeScript, Tailwind/shadcn, Supabase Auth, Postgres with Drizzle, Inngest, Stripe, PostHog, and a growing set of AI and data providers—plus dedicated paths for scraping and batch execution where latency and throughput matter.
Visa sponsorship is not available for this role.
