Platform EngineerPrincipal1 position

Why This Role is Different

Frontier Development Role

Architect and build the trust ledger that turns abstract reputation metrics into immutable, verifiable records. This role blends deep cryptography with distributed systems to deliver a production‑grade blockchain that satisfies regulators and incentivizes honest participation.

The Frontier Element

You will pioneer recursive zero‑knowledge proof integration in a real‑time federated learning ledger, enabling end‑to‑end privacy guarantees without exposing sensitive data, a first in the industry.

Project Context

Research Area

Blockchain‑Enabled Trust Ledger (BLTL) and Recursive ZKP Audit

From: Trust‑Aware Federated Aggregation in Multi‑Agent Settings

Why This Role is Critical

The BLTL provides the immutable audit trail and token‑based governance that make TAFA regulatory‑compliant and tamper‑resistant. A dedicated platform engineer is essential to weave together lightweight smart contracts, recursive ZKPs, and sharded ledger architecture into a seamless, low‑overhead system.

What You Will Build

A sharded, permissioned blockchain that records reputation scores, ZKP commitments, and governance token balances; recursive ZKP generation/verification pipelines; and a developer‑friendly SDK for clients to submit ZKPs and stake tokens.

🛠

Key Responsibilities

  • Design and implement a lightweight, sharded smart‑contract chain that records reputation scores, ZKP commitments, and token balances.
  • Develop recursive ZKP generators and verifiers that prove DP compliance and reputation weighting without revealing private parameters.
  • Create a token‑staking contract that enforces economic deterrence against malicious clients.
  • Build an SDK and CLI for edge clients to submit ZKPs, stake tokens, and query ledger state.
  • Collaborate with the QRAC and ADPL teams to embed ledger interactions into the aggregation workflow.
