Lead System Architect

Company Description

At the Data Vault Project, we’re building a secure data vault and permissioned sharing layer designed to put individuals and organizations in control of their information. Through privacy-first architecture and flexible access controls, users choose what data is shared, with whom, and for how long — with the ability to revoke access at any time. Our goal is to create infrastructure that enables secure, transparent, and user-governed data exchange in an increasingly AI-driven world.

About the role

We're looking for a Tech Lead / System Architect to own the overall system design for a sensitive-data product. You'll define the blueprint, set technical standards, keep work aligned across components, and guide implementation through reviews.

What you'll do

• Own the end-to-end system design so components work together safely
• Define clear interfaces between components and keep them consistent over time
• Make key technical decisions and document tradeoffs, risks, and scope
• Guide engineering execution through design/PR reviews (part-time weekly review is OK)

Required (must-have)

• Led system design for a product handling sensitive data (health/finance/identity)
• Can define and maintain clear APIs/interfaces across components
• Can make decisions and document them clearly (what's in/out, risks, tradeoffs)
• Experience guiding other engineers through reviews and unblocking work

Nice-to-have

• Experience with audit logging or compliance-style record keeping
• Experience with permission-based sharing systems

Compensation

Commensurate with experience and scope of responsibility
