About the Role
zerohash's Applied AI team manages an internal Intelligence Core and external agentic-commerce products. This role serves as the engineering backbone, building the access layer, audit logging, skills/agents, and system architecture. The core objective is to securely connect company systems and produce verifiable records of agent actions. This role is strategically important as the internal build acts as a sandbox for agentic commerce products, proving identity, authority, write permissions, and tamper-evident logging before powering multi-institutional agentic networks.
Responsibilities
- Own the access layer (native connectors, MCP servers, Databricks US/EU) using short-lived tokens, least-privilege read-only access, and zero raw PII while enforcing data residency.
- Define a versioned schema for two signed record types of credentials and action records, in one namespace so each can be checked against the other.
- Establish build discipline early: deployment pipelines, authority policy as code, skill merge gates, and signed builds with SBOMs.
- Build the authority lease service with integrated kill switches.
- Capture events into append-only, hash-chained logs for tamper-evident and independently verifiable auditing.
- Migrate the team’s existing agents onto the Core, launch new per-department agents and lead security reviews for continuous read access.
- Extend the Core from read to bounded write: logged actions, idempotency keys, compensating actions, and multi-approver time-locks for anything that moves money.
- Design core primitives for cross-institution interoperability, wrapping actions in signed mandates, scoped authority, and attestation receipts compatible with standards like x402, AP2, and MPP.
- Design self-hosted, zero-egress private stacks when required by classification evidence.
- Evaluate and integrate state-of-the-art developments in agent frameworks, confidential inference, and zero-knowledge attestations.
- Maintain a security-first posture by threat-modeling prompt injection, credential exfiltration, and confused-deputy risks upfront.
Requirements
- Senior, Python-first backend engineering with production experience in event-driven systems, API integration, and CI/CD.
- Agent-system experience — composing LLM agents (Claude, GPT, or comparable; Bedrock or comparable platforms) into standing systems — with the judgment to keep the models at the edges and the control plane deterministic.
- Demonstrate security-first habits in a regulated environment (MSB/VASP, bank, or comparable): least privilege and read-only as reflexes, not requirements to be reminded of.
- Working familiarity with capability-based authorization: attenuable tokens, workload identity, policy-as-code.
