Job description

Product Engineer

ENGINEERING | San Francisco, New York City | On-site | Full-time

The Role

Full Stack Engineers at Rowspace are at the heart of building our product. You’ll shape the platform from the ground up. In a typical week, you might build a pipeline that turns 50-page investment memos into searchable knowledge in seconds, design a UI that helps analysts trace AI answers back to source documents, or ship a custom agent workflow based on feedback you heard from a customer that morning.

What You’ll Do

• Design and build intuitive user interfaces that become deeply embedded in investors’ daily workflows
• Build APIs that allow Rowspace to work seamlessly across chat tools, custom workflows, and external applications—such as ChatGPT, Claude, and Excel
• Build ingestion pipelines that turn messy, scattered data, such as PDFs, emails, spreadsheets, structured data, into a unified knowledge engine that underlies all of our products
• You’ll talk directly to customers, hear their pain points firsthand, and ship solutions within days
• You will be responsible for maintaining the highest standards of security, privacy, and system reliability as you work with sensitive investment data
• You will build comprehensive eval sets to ensure the reliability of our LLM systems

Who You Are

• You’ve shipped full-stack products before (React/Typescript + Python/Node or similar)
• You’ve designed data models and APIs at scale and enjoy the challenge of getting the schema right
• You’re excited about productionizing AI, not just using LLMs, but building reliable products to deliver value to customers
• Bonus if you’ve touched finance or fintech, but we’ll teach you the domain if you’re a fast learner who’s genuinely curious about how investors think and work
• You care deeply about engineering craft—continuously improving your workflows, sharing learnings with your team, and raising the bar for quality
• You want to be early. This is a chance to be among the first 20 engineers at a fast-growing Series‑A startup with high ownership, high impact, and high iteration speed

Perks & Benefits

• Health & Wellness: Comprehensive medical, dental, and vision insurance
• Future Planning: 401(k) plan including employer match on contributions made while employed by Rowspace
• Time Off: Unlimited PTO policy—we trust you to take the time you need to recharge
• Food & Fuel: Monthly commuter stipend, plus free daily lunch and a fully stocked snack bar in the office
• Team Culture: Regular team offsites to bond and strategize away from the desk
