Product Engineer / Builder

What you'll do

Ship product end-to-end. Build the analytics engine that finds saving potential across millions of rows. Turn AI advances into real production features - anomaly detection, opportunity scoring, agentic workflows. Build customer-facing flows in React/Next.js that feel more like a great CRM than a spreadsheet. Identify the right problem, align, and drive it to revenue. Don't wait for a PRD. ## Who we're looking for

Strong engineers or every seniority level, deeply AI-immersed, who care about the output more than the craft. - Shipped real production software in a modern product team (B2B SaaS, analytics, or data-heavy products a plus). - Live in AI tools daily. Cursor, Claude, Codex, agents - whatever ships fastest. You've already built something AI-leveraged that wouldn't have existed otherwise. - Depth in modern Python (FastAPI, async, SQL) or TypeScript/React/Next.js - and motivated to go up and down the stack. - Comfortable with data and SQL. ClickHouse a plus. - Think in domains, not endpoints. Suppliers, materials, contracts, indices. - Have built AI-backed product features, or are obsessively learning to. ## What We Offer

The people at Tacto are passionate about building the organization, growing themselves, and our product while having fun and being real. We have high expectations, great talent density, and a culture where your ambition, performance, and agency are what count - not where you come from or how big your ego is. You'll grow at the forefront of AI, have real ownership and impact, and be surrounded by the best people in their field who challenge you and make you better every day. That is demanding and rewarding, but that's where we thrive.
