Senior Software Engineer

About The Position

We are building G-P’s permanent Horizon 3 (H3) Discovery Engine—an autonomous unit unconstrained by existing corporate assets, designed to explore big macroeconomic shifts, workforce evolutions, regulatory shocks, and AI-agent economies. This isn't an internal infrastructure team or a traditional engineering department; it is an agile builder pod that shifts code, breaks assumptions, and runs fast, low-fidelity experiments to find product market fit.

This is a co-founder-level engineering role working in a tight, single-threaded Pod alongside a Principal PM / Product Builder. You will have dedicated executive "air cover" to bypass traditional corporate roadblocks, legal procurement delays, and enterprise architectural overhead. This role demands extreme ownership, a relentless bias for shipping over talking, and a knack for building "sketchy V0s" that capture behavioral data rather than scale. If you want to spend months writing architecture design docs before typing a line of code, this isn't for you.

What You Will Do:

• Extreme Product Ownership: Drive the technical discovery, design, API contracts, and rapid discovery of net-new business concepts.
• Ship Weekly Behavioral Probes: Collaborate with your PM counterpart to build and launch weekly "sketchy V0s," fake-door landing pages, and concierge MV
