About Aztec At Aztec, our goal is to add privacy to Ethereum. In the current public blockchain paradigm, users and entities unknowingly broadcast data in the public, compromising privacy and security to get trustlessness. Not only are unencrypted blockchains inherently privacy-exposing, they require significant redundancy to compute and verify the legitimacy of transactions. Implementing scalable encryption in a public blockchain paradigm requires cutting-edge math and engineering. Thankfully, our team of scientists and engineers invented Plonk, the industry-standard zkSNARK, and Noir, the universal language of zero knowledge. Now, we’re building a first of its kind Layer 2 with private smart contracts. This requires new cryptographic primitives, a zero-knowledge DSL for writing contracts, a privacy-friendly execution environment, a carefully designed set of circuits that prove the validity of the chain to L1, a decentralized block-building and proving mechanism, and a top-tier user and developer experience. And it’s now time to bring it to market. We’ve raised $125 million from industry-leading investors including a16z crypto, Paradigm, Variant, Consensys, and a_capital, and we’re growing quickly.Role focus: We're looking for an experienced full stack engineer with a passion for the devops side of the engineering process. You'll want to dig into all areas of our codebase, to develop an understanding of how each part builds, fits together, and deploys. Key Responsibilities

Evolving code across the stack to improve compile and test times. Our CI system. The product behind the product. You'll help maintain it, and keep engineers engineering. Our deployments. You'll make sure that what we build can easily and reliably be deployed, and that it stays running. Our metrics. You'll help ensure we're getting useful data and benchmarks from our code, and use appropriate tools to visualise. To be effective in the role: You'll need a deep understanding of the tools that we use and how best to use them. You'll have the ability to identify areas of improvement, whilst prioritising simplicity and ease of maintenance for all engineers. You'll have an attention to detail, noticing inefficiencies and inconsistencies and digging in to resolve them. You'll pro-actively speak to team leads, identifying areas of weakness within their devops flow, and working with them to improve. You can take direction when needed, but likewise can self start when given the freedom. The current responsibilities are currently handled ad-hoc as needed by engineers. While there will continue to be support, we need someone with bandwidth to continuously focus on and improve these areas.
