Core Architect & Integration Lead — Applied AI; Fully Remote

• Act as the engineering backbone for the Applied AI team, building the access layer, audit logging, and system architecture.
• Connect company systems securely and produce verifiable records of agent actions.
• Extend the core from read to bounded write with signed mandates and attestation receipts.

Key Responsibilities:

• Own the access layer with short-lived tokens, least-privilege access, and zero raw PII.
• Define versioned schemas and build the authority lease service with integrated kill switches.
• Capture events into append-only, hash-chained logs for tamper-evident auditing.

Requirements:

• Senior Python-first backend engineering experience with event-driven systems and CI/CD.
• Experience composing LLM agents into standing systems with deterministic control planes.
• Security-first habits in regulated environments (MSB/VASP, bank, or comparable).
• Healthcare, vision, and dental insurance with premiums largely covered.
• Equity, maternity and paternity leave, WeWork access, and WFH/L&D stipends.
