Parity Technologies builds core infrastructure to power a better internet—one that respects the freedom and data of individuals—and to empower developers to create better services through decentralized tech. Parity’s technologies include Substrate, a flexible framework for quickly building blockchains, and  Polkadot, a protocol for connecting and securing blockchains. We are looking for a Security Operations Engineer to have a vigilant eye on our architecture, tooling and infrastructure with the goal of making our operations as secure and reliable as possible. The goal of the Staking Ops team is to ensure security, reliability, and health of the Polkadot network from a foundation level with the operation of node infrastructure to validate all activity across Polkadot and other substrate based networks.  Responsibilities

  • Design and implement secure cloud and on-premise infrastructure to validate on substrate based networks.
  • Work within systems that secure millions of dollars of cryptocurrency from motivated attackers.
  • Instrument high-signal alerts from production infrastructure events to provide early indicators of network attacks and compromises. Create playbooks of what to do in the case of such events.
  • Model and evaluate risks of slashing for validator nodes from an operational perspective and prioritize security efforts based on these risk assessments.
  • Monitor for unsafe and uncertain conditions and design fallback systems to support the stability of the network.
  • Work with infrastructure and core runtime engineers to design and implement hardened, layered systems.
  • Work with security engineers around securing digital assets in a production environment
  • Respond to security alerts and triage incident response management.

  • Experience engineering and operating 24/7 public-facing infrastructure.
  • Ability to debug complex systems running in uncertain environments.
  • Experience evaluating risk and implementing security detections and protections.
  • Experience instrumenting infrastructure with a variety of detections that provide high-signal, early indicators of intrusion and dangerous misconfiguration.
