It is at $3M ARR with 200+ consumer brand customers, is venture backed, and has a team of about 13, fully in person in New York.

The role

You would be the 4th product engineer. You will own large parts of the quarterly goals set by the founders and decide for yourself what to build to get there, from improving the current product to launching new ones from 0 to 1.

What you'll do

• Own large parts of the founders' quarterly goals, such as getting every customer to use the agent from Slack, and decide what to build to hit them.

• Take ownership of product outcomes from start to finish, building out the current product and launching new products from 0 to 1.

• Work directly with customers to understand their problems, ship quickly, gather feedback and iterate.

• Build production agents that do real, high-stakes work managing million-dollar ad budgets, including the harness, memory, learning loops, tools and user-facing interface.

• Ship features end to end across React, Python, Postgres and ClickHouse: design the systems, build them and polish the UX.

• Use coding agents and AI to automate your own work and keep raising product quality and speed.

What we're looking for

• 2 to 10 years of experience as a full-stack engineer (up to about 12 for exceptional profiles). Candidates with under 3 years need standout signals, such as fast growth or strong side projects.

• Real full-stack depth: you have built large features end to end across both front end and back end. Engineers who have only lightly touched one side are not a fit.

• A history of owning products, such as taking something from 0 to 1 or working directly with customers to shape and ship features, for example at a seed to Series A startup or on a small new-launch team.

• Product taste: you enjoy studying other products, critiquing UI and UX, and choosing the right problems to solve.

• A high-ownership, high-intensity mindset for a demanding, in-person culture.

Bonus points

• Experience building production AI agents.

• Experience with data-intensive products or ClickHouse.

• Big tech experience where you clearly took on outsized ownership and worked full stack.

Tech stack: React, Python, Postgres, ClickHouse, AI agents and LLMs.

Compensation and benefits

• Base salary: $180K-$240K

• Competitive equity

• Medical, dental and vision insurance

• 401(k) contributions

• Hotel accommodation for the first 2 to 3 weeks for candidates moving to New York

Location and work model

• Tribeca, New York, NY

• 100% on-site, 5 days a week, with in-person onboarding

• An intense culture: at least about 50 hours a week, aiming closer to 60, with weekends generally off

• Open to visa transfers (for example OPT and H-1B transfers)

• Full-time
