Head of Blockchain Infrastructure

You have experience being responsible for the operation high stake infrastructure systems and are familiar with all that this entails, such as hardware and software infrastructure management, security, resource planning, communications with the wider team and working in a highly independent and self-directed fashion. You can thrive in a fast-paced and innovative startup environment, and you are not deterred by unknowns or unfamiliar concepts.

You are currently running validator nodes for a proof-of-stake blockchain, commercially or personally. You understand the implications of protocol changes, e.g. in the context of forks and have been immersed in the blockchain world for some time.

You communicate clearly in writing and in discussions, and you are always on the lookout for ways to improve the performance, profitability, and usefulness of the nodes you are running. You love implementing efficient and highly secure systems, and have a deep rooted appreciation for how implementation details affect the big picture, and vice versa.

RESPONSIBILITIES

• Manage the company’s validator node operations across several testnets and mainnets using Autonity, a new dPoS BFT L1 protocol, and in this context be responsible for internal SLAs and committed to KPIs;

• Design and implement processes around validator node operations, such as incident response, key management, change management;
• Work closely with the Clearmatics Autonity development team;
• Create and define processes to extract maximum value from validator operations (including staking/bonding of stake; reaping of validator rewards) and reduce loss risks;
• Provide training and guidance for other members of the infrastructure team, or your own direct reports, to ensure 24/7 node operation;
• Communicate technical details via open source documentation;
• Work with various teams and the wider community to engage with new trends and opportunities revealed by internal data, blockchain research and the wider blockchain industry.

REQUIREMENTS

• Experience running validator nodes for a proof-of-stake blockchain, commercially or as a tinkerer;
• Ability to demonstrate a deep understanding of the implications of protocol changes, e.g. in the context of forks;
• Experience managing and running high stake infrastructure
• Experience with cryptographic key management on production systems;
• Familiarity with deploying and testing production software in various cloud environments;
• A deep and detailed understanding of accountability, consensus algorithms, and real-world risks, with a particular focus on financial and reputational implications;
• The ability to work closely and in detail with technical and research teams for the practical exploration of scenarios; testing; and continuous improvement.
• Ability to reason about the economics and incentive structures of a blockchain system confidently

NICE TO HAVE

• Experience managing validator nodes for a delegated-proof-of-stake Byzantine Fault Tolerant blockchain mainnet;
