Behind every system we build, there are people who answer for it.
01THE FOUNDERS
Different disciplines. Shared conviction.
The engineering that makes AI accountable. The medicine that asks what accountability should mean for a person.

03THE NEXT CHAPTER HAS AN OPENING
01 OPEN ROLE / ENGINEERING LEADERSHIP
CTOChief Technology Officer
A building job with a CTO’s title.
Write production code daily. Own implementation architecture and delivery. Build the engineering team behind you.
This is a daily production coding role. You will own the implementation and the team that delivers it.
—
Write production code alongside the team, using TypeScript, Next.js, and Firebase/GCP.
—
Own implementation architecture, delivery, release, and production operations.
—
Take DeBrah through App Store and Play Store submission, review, and lifecycle.
—
Set code quality, code review, and CI/CD standards.
—
Hire and lead the engineering team, beginning with a Founding Engineer; you recommend, the CEO decides.
—
Own production operations for a product used by people who may be in distress, and serve as the internal technical owner for SOC 2 Type II evidence.
02 / 04
Clear ownership from day one.
The CEO built the codebase, serves as CISO, and owns product direction. The division of responsibility is explicit.
—
CTO: implementation architecture, technical design, delivery, releases, production operations, code quality, review standards, CI/CD, and app store lifecycle.
—
CTO: hiring and engineering leadership. You recommend; the CEO makes the hiring decision.
—
CEO: product direction and roadmap priorities; the security and compliance program.
—
CEO: final decisions on trust posture, regulatory position, and the patent; investor, enterprise, and federal technical representation; company technical narrative and external materials.
—
How something gets built resolves with the CTO. What gets built, or anything reaching a regulator, auditor, or investor, resolves with the CEO. Both parties sign this scope agreement.
03 / 04
Bring work we can talk about.
You still ship code. You can point to something you built in the last twelve months and explain the decisions behind it.
—
Production TypeScript on Firebase or GCP at real load, with direct operating experience.
—
Real work under regulated scrutiny: healthcare, financial services, federal, or another environment with an auditor, assessor, or ATO.
—
The ability to improve a large, working codebase without proposing a rewrite.
—
App Store delivery experience, including a rejection you personally resolved.
—
Experience hiring engineers and explaining how those hires developed.
—
Comfort working directly with a technical founder who built the product.
