[Applied in Coupang.Jobs] Equal Opportunities for All

Coupang is an equal opportunity employer. Our unprecedented success could not be possible without the valuable inputs of our globally diverse team.

About Us

AXQ Capital is a global quantitative investment firm with offices in New York, Beijing, Shanghai, and Hong Kong. We pursue consistent alpha through rigorous scientific research and sustained investment in technology and data infrastructure. Our strategies are deployed across global markets, spanning multiple geographies, asset classes, and trading horizons.

Job Duties 

As an AI Engineer, you will build the next generation of agentic AI research infrastructure. Working closely with our quantitative research team, you will push the frontiers of modern AI — with the rare advantage of real financial market feedback as your ground truth.

• Design and build a multi-agent framework for quantitative finance research
• Develop tools and deep integrations with AXQ's proprietary research infrastructure
• Research frontier model capabilities and develop rigorous agentic evaluations
• Partner with quantitative researchers to create best-in-class system observability, well-grounded research pipelines, and novel research ideation methods
• High-performing candidates may also contribute directly to model work, including post-training

Qualifications

• 2+ years of experience in software engineering, machine learning, AI research, or a related role
• Bachelor's, Master's, or PhD from a top-tier university in a quantitative or technical discipline (mathematics, physics, statistics, computer science, or similar)
• Strong foundation in statistics and machine learning fundamentals
• Deep, practical knowledge of agentic systems, pre/post-training evaluations, or related AI engineering domains
• Prior experience in quantitative finance is not required
• Self-motivated and highly productive, with a strong sense of ownership and a bias toward action

This is a Next Generation PM Role. AI has fundamentally changed what it means to build software. The best product people no longer just write specs and hand them off—they prototype, ship, and iterate with AI-powered tools at a pace that was unimaginable two years ago. We're looking for someone who has already crossed that line: a product leader who builds, not just plans.

About Conviva Conviva is the intelligence layer for digital businesses, turning every consumer interaction into outcome-based intelligence—linking engagement patterns across AI agents, apps, websites, and streaming video to real results such as purchases, bookings, and resolved support requests. Powered by its patented Time-State Technology®, the Conviva® Operational Data Platform delivers real-time insights and automation that help leading enterprises grow, improve satisfaction, and build lasting trust.

The Opportunity AI agents are quickly becoming a new "digital surface" alongside mobile and web. But teams still struggle to answer basic questions: Are my agents working and achieving outcomes? What drives success? How do we optimize behavior, reliability, and user outcomes? How do I launch an agent and have it continuously adapting to the ever-changing world?

Conviva has an industry-leading answer to these questions. This role is a chance to define and lead a brand-new category: analytics and optimization for AI agent experiences, backed by strong platform foundations, real customer problems, and a track record of disruptive innovation.

You won't just manage this product—you'll build it. You'll use AI coding tools to prototype features, validate ideas with working software, and move from insight to artifact faster than any traditional product process allows. You'll work at the intersection of product strategy and hands-on creation, partnering with engineering, design, and go-to-market to ship quickly, learn constantly, and set the direction for where agent analytics goes next.

Why "Product Builder" and Not "Product Manager" The rise of AI-assisted development has created a new kind of product professional—one who can go from customer insight to working prototype in hours, not weeks. We call this role a Product Builder because:

• Build to think: Instead of writing a 20-page spec, you spin up a working prototype to test your hypothesis. Your artifacts are software, not slide decks.
• AI-native workflow: You use AI coding tools as a force multiplier—not to replace engineers, but to close the gap between "idea" and "something customers can react to."
• End-to-end ownership: You own the product from strategy through execution. You don't toss requirements over the wall; you're in the code, in the data, and in front of the customer.
• Still a product leader: This is a PM-first role with builder superpowers. You lead product strategy, customer discovery, and prioritization—and you also ship.

What Success Looks Like

Product Vision & Strategy

• Own product outcomes: defining vision, strategy, roadmap, and success metrics.
• Discover and define the category: talk to customers weekly, map workflows, validate problems, and translate insights into sharp product bets.
• Turn ambiguous, fast-moving market signals into clear product direction with strong conviction.

Build & Ship

• Use AI development tools (Cursor, Claude Code, Windsurf, Replit, v0, etc.) to rapidly prototype concepts, validate UX hypotheses, and create working demos that accelerate team alignment and customer feedback.
• Partner deeply with engineering, design, and data/ML to ship high-quality product experiences from concept to launch to iteration.
• Create internal tools, dashboards, and proof-of-concept applications that solve immediate team or customer needs.

Execution & Leadership

• Drive execution: prioritize ruthlessly, unblock teams, manage tradeoffs, and ensure timely delivery.
• Bridge the gap between product thinking and technical implementation—you should be equally comfortable in a customer interview and reviewing a system architecture.
• Contribute to a culture where building is the default mode of exploration, not just analysis and documentation.

Who You Are

Product DNA

• 5–10+ years in product management, with meaningful experience in analytics, data platforms, developer tools, or AI/ML products.
• Energized by 0→1 ambiguity and can turn fuzzy problems into crisp product direction.
• Customer-obsessed but practical—deep empathy plus strong prioritization.
• Communicate clearly in writing and in live discussions. Can zoom out (strategy) and zoom in (details) without getting stuck in either.
• Build alignment fast and keep teams moving.

Builder DNA

• Actively use AI-assisted development tools (e.g., Cursor, Claude Code, GitHub Copilot, Replit, v0) to build prototypes, internal tools, or production-adjacent artifacts. Show us what you've built.
• Comfortable reading and modifying code (Python, JavaScript/TypeScript, SQL, or similar). You don't need to be a senior engineer—but you can't be code-averse.
• Engineering background, CS degree, or equivalent hands-on technical experience is strongly preferred.
• Experience with or strong interest in: LLM application development, agentic systems, RAG architectures, prompt engineering, or AI evaluation frameworks.
• Have shipped something you personally built (side project, internal tool, prototype, open-source contribution)—not just managed the backlog for.

Bonus Points

• Experience in digital experience analytics, observability, or APM.
• Familiarity with conversation analytics, agent evaluation, or LLM-ops tooling.
• Published writing, talks, or open-source work demonstrating thought leadership at the intersection of product and AI.
• Experience building with AI agent frameworks (LangChain, CrewAI, AutoGen, etc.).

What We Offer

• A front-row seat to a category being created in real time—agent analytics is where web analytics was in 2005.
• A team that values builders: we don't just talk about AI, we use it every day to move faster.
• A hybrid role where you shape both the "what" and the "how"—strategy meets craft.
• Competitive compensation, equity, and benefits.

If you've ever thought "I wish I could just build this instead of writing another PRD"—this role is for you.
