About The Position

We're building an AI-native platform that helps marketing and creative teams at top e-commerce brands understand which ads are working and ship more winning creative across the major ad platforms. We're a Series B remote-first team. We've been growing 2.5x year over year, led by second-time founders (currently just under 100 headcount). AI isn't a feature here: it's the foundation of our product and of how we build. This role sits on our platform team: designing, building, and maintaining the backend APIs and services the rest of engineering builds on, as our AI workflow platform scales to many times its current surface. Sample projects include building a unified API for our insights data and storing metrics from our data providers at scale.

Requirements

Node.js and TypeScript experience (strong engineers from similar stacks transfer well).
Experience architecting backend systems that other teams build on, owning the service boundaries, data models, and API contracts in production.
Experience leading complex, multi-engineer backend projects from design through production, and being the technical decision-maker when trade-offs were contested.
AI-native development habits: directing AI coding tools (Claude Code, Cursor, Copilot, or similar) through much of your output, and rigorously reviewing and owning what ships.
Experience designing asynchronous, event-driven systems (queues, background jobs, messaging) that run under real production load, not just consumed them.
Experience owning hard third-party integrations end to end, including auth, rate limits, retries, and failure modes.
Experience simplifying data architecture at scale: schema design, ETL pipelines, and storage choices (PostgreSQL, MongoDB, or other document stores) that held up as data volume grew.
6+ years building and maintaining large-scale software applications, with recent years operating at a Staff or Lead IC level: setting technical direction, not just executing it.
A track record of taking products from 0 to 1, ideally at Series A to C startups.
Comfort with a fast pace: short project cycles, evolving requirements, high ownership.
Exceptional written and verbal communication, including translating technical issues into business impact.
Experience building or integrating LLM-powered product features or agent systems.
Able to work with significant overlap to Eastern Time.
