Founding Engineer
About the role
Founding Engineer role at Orange Slice (YC-backed) focusing on owning major slices of the product and infrastructure, shipping user-facing features, hardening core systems, and helping define how to scale.
Responsibilities
- 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: ship improvements to multi-step agentic research workflow and take primary ownership of Inngest pipeline with event design, step boundaries, retries, observability hooks, and safe rollout patterns.
- 60 days: own a measurable slice of production reliability; reduce a class of failures and instrument for observability.
- 90 days: lead a multi-sprint initiative with before/after production metrics.
Qualifications
- Strong TypeScript and comfort owning features full-stack (React/Next patterns, server routes, database design).
- Bias to ship: milestone-driven, simple designs, iteration with real users.
- Systems thinking: focus on idempotency, failure modes, operational clarity.
- Product sense: understanding user needs and data quality/AI outputs.

About Orange Slice
AI agents that find you customers who already want to buy
Orange Slice uses AI agents to crawl the internet for temporal signals/firmographic data that help sales teams find high-intent prospects by continuously monitoring the internet for buying signals and firmographic changes. Our agents scan millions of data sources - including company websites, news articles, job postings, press releases, and social media - to detect meaningful events such as leadership changes, product launches, funding rounds, hiring trends, and more. These insights are transformed into actionable sales signals that indicate a company’s likelihood to purchase your product. With Orange Slice, revenue teams can prioritize outreach, personalize messaging, and dramatically improve conversion rates by engaging the right accounts at the right time - based on what’s actually happening, not just static firmographics.
