Senior Product Engineer - US

Coefficient is a VC-backed startup building the next generation of data software. The founders, Navneet & Tommy, are serial entrepreneurs whose last startup, Shopular, was backed by Y Combinator and Sequoia and acquired by Rakuten Ebates.

We started by turning spreadsheets into a live, connected layer on top of company data—bringing systems like Salesforce, HubSpot, and Snowflake directly into Google Sheets and Excel. Today, thousands of teams rely on Coefficient to access real-time data without IT.

Now, we’re taking the next step.

Coefficient is evolving into an agentic data intelligence platform — where AI doesn’t just retrieve data, but understands it, reasons about it, and takes action.

At the core is a shared data world model: a unified, continuously updated understanding of a company’s data, business logic, and context. This allows our autonomous agents to operate with far more context than traditional tools—unlocking a fundamentally new way to work with data.

Instead of dashboards and one-off queries, we’re building AI agents that:

• Develop context over time (memory + business rules)
• Explore data and surface insights proactively
• Execute workflows and make decisions
• Generate complete, high-quality outputs (reports, dashboards, spreadsheets, scripts)

All powered by the real-time, production-grade data pipelines we’ve already built.

The shift is simple: from tools that show you data → to autonomous agents that do work with it.

We’re looking for experienced Product Engineers who operate with high agency, strong ownership, and deep curiosity.

This is not a scoped, ticket-driven role. You’ll work directly with the founders to define product direction, build core systems, and ship end-to-end experiences.

You might be a fit if you:

• Take full ownership of problems—from idea to production
• Are relentlessly curious and think from first principles
• Move quickly, make decisions, and iterate without perfect specs
• Care deeply about product quality, UX, and craft
• Thrive in ambiguity and low-structure environments

Technical expectations:

• 6+ years of experience building production web applications
• Experience with modern web stacks (e.g. TypeScript, React, Next.js, or similar)
• Experience with backend systems and APIs (e.g. Node, Python, Flask, or similar)
• Comfortable working with data-intensive applications and distributed systems
• Ability to pick up new technologies quickly and move across the stack as needed
• Solid understanding of performance, system design, and scalability
• Experience building and shipping production systems

This is a hybrid in-office role in San Mateo, CA. We are looking for this person to be in-office three days a week with our team.

We’re building toward a future where autonomous agents, powered by a shared data world model, can understand a business and execute work on its behalf. If you’re the kind of engineer who wants to build systems like that—and take real ownership in the process—you’ll do well here.

• Medical, Dental and Vision Insurance
• Unlimited PTO
• Parental Leave
• 401K Plan
