Founding Architect & All-Around Engineer

About Vibranium Labs

Join us on an exhilarating mission at Vibranium Labs, a VC-backed startup funded by leading investors including Calibrate Ventures, Mirae Asset, Plug and Play, Gaingels, and others. You'll work directly with Tim Hwang (Founder and Chairman of FiscalNote (NYSE: NOTE)), alongside our co-founders who bring deep AI and engineering experience from Google, Amazon, Workday, and Instacart. We’re building Vibe, an Agentic AI platform that autonomously manages and resolves incidents, redefining the future of on-call engineering.

We’re a fast-paced, mission-driven team focused on turning convoluted reliability workflows into intelligent, proactive systems. If you're obsessed with AI, fluent in the latest LLM advancements, and energized by the challenge of building deeply technical products from scratch, we want to hear from you.

We’re in the earliest stages—already partnering with Fortune 500 companies—and now we’re looking for a Founding Architect & All-Around Engineer to help us scale from a functional MVP to a robust, production-ready platform.

About the Role

We’re hiring an exceptional, deeply technical generalist to work as the CTO’s right hand: driving architectural decisions, shipping core features, and diving into any layer of the stack. This is a founding team role with significant ownership and responsibility.

We’re not looking for specialists. We’re looking for someone who can think broadly and execute deeply; someone who’s excited to build across backend infrastructure, frontend systems, and AI-powered workflows. You should thrive in ambiguity, take pride in owning problems end-to-end, and have the scars and wisdom to design both scalable systems and scrappy solutions, depending on the moment.

Why Now? Why Vibranium Labs?

- Zero-to-one impact. Shape not just the product, but the company itself
- Work with top-tier team. Work with top-tier engineers, advisors, and AI-native operators
- Meaningful equity upside. Plus full ownership of your work
- Enterprise traction + early validation. Customers include Fortune 500s

What We’re Looking For

- You care about the why. You’re user-obsessed, love talking to customers, and enjoy translating fuzzy requirements into sharp product thinking.
- You have grit. You’re energized by tough problems, unfazed by ambiguity, and willing to do whatever it takes—long hours, unfamiliar code, or last-minute pivots—to push the product and company forward.
- You live and breathe AI. You actively follow LLM trends, experiment with new tools (OpenAI, Claude, LangChain, etc.), and have strong opinions on prompting, context windows, embeddings, and RAG strategies.
- You ship fast and smart. You’ve built full-stack products end-to-end, ideally in startups or high-ownership roles.
- You know how to scale. You’ve architected and delivered full-stack applications that are robust, scalable, and ready for production, balancing speed with sound engineering principles.

Other Information

- Salary range: $160,000 – $200,000
- Equity: Founding-level equity grants
- Experience: 5+ years of professional engineering experience preferred
