About the Job

zerohash's Applied AI team manages two fronts: an internal Intelligence Core (a system connectivity and control layer) and external agentic-commerce products. This role acts as the engineering backbone for both - building the access layer, audit logging, skills/agents, and system architecture. The Applied AI team builds the Intelligence Core itself. Engineering maintains platform accounts, event hooks, and retrieval layers; this role builds everything above them.

Core objective

Connect company systems securely, and produce records of agent action that a third party can verify.

Strategic importance: The internal build acts as a sandbox for agentic commerce products. Identity, authority, write permissions, and tamper-evident logging will be proven internally before powering multi-institutional agentic networks.

Key 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.

Qualifications & 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.

Preferred

Verifiable credentials, HTTP message signatures, or any of the emerging agent-payment mandate schemes (x402, AP2, MPP, Visa TAP, Mastercard Agent Pay).

Self-hosted LLM stacks; confidential computing / trusted execution environments.

A research habit and autonomy

this is a foundational seat on a new team, with wide scope and few hand-holds.

Perks & Compensation

Healthcare Insurance

zerohash covers roughly 100% of employee premiums as well as a portion of spouse/children (U.S. only)

Vision & Dental Insurance (U.S. only)

Chance to earn equity

Maternity & Paternity leave (after 6 months)

WeWork All Access Membership

WFH Yearly Stipend

L&D Yearly Stipend (after 6 months)
