Principal Software Engineer

Job title: Prinicpal Frontend Engineer 💻🎨⚛️

Location: San Francisco Bay Area 🇺🇸 🌁

Compensation: $350,000 base salary plus bonus 💸

Harrison Clarke Ventures is currently partnered with multiple tier 1 VC-backed AI/ML startups across HealthTech, Fintech, Greentech and AI within the US. We're on the hunt for Staff Frontend Engineers who know how to build 0-1 customer-facing AI-native products and have seen those products scale to Hundreds of thousands of users

What you'll be doing

You'll be embedded with a high-growth AI startup, owning the frontend from the ground up. That means shaping product architecture decisions early, working closely with founders and product teams, and building interfaces that make complex AI capabilities feel simple and intuitive to end users.

What we're looking for.

• 6+ years of front end engineering experience, with at least one 0-1 product build under your belt.
• Deep proficiency in React and modern TypeScript
• Experience scaling frontend infrastructure to support large, concurrent user bases
• A strong eye for UI/UX you care about what you ship, not just that it ships
• Comfort working in fast-moving, ambiguous environments where priorities shift
• Bonus: experience integrating LLM APIs, streaming interfaces, or real-time data pipelines

What's on offer

• Equity in a company on an early growth trajectory
• The chance to work on products that are genuinely defining a new category

Who this is for

This is not a maintain-and-iterate role. If you're energised by greenfield builds, want your fingerprints on a product from day one, and are drawn to the AI space, we want to hear from you.

Interested?

We move quickly and keep the process tight, typically three to four conversations from first call to offer.
