Web3 TypeScript ZK Jobs

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.

• Design and implement IaC, CI/CD pipelines, and automation to minimize lead time across the stack
• Develop and enforce best practices for observability, monitoring, alerting, and incident response to minimize MTTR
• Architect and implement scalable, secure, and cost-efficient cloud infrastructure (GCP/AWS)
• Lead technical design discussions, post-mortems, and architecture reviews as they pertain to the systems described above
• Identify and proactively address performance bottlenecks, cost inefficiencies, and system vulnerabilities as they pertain to the systems described above
• Keep a cool head when on-call
• Do all the other good stuff that pragmatic, seasoned engineers do

Desired Skills and Experience:

• 7+ years of relevant industry experience

• Hands-on proficiency with *Infrastructure-as-Code (Terraform, etc.)*, container orchestration (Kubernetes), and CI/CD pipelines
• Experience with *observability stacks* (Prometheus, Grafana)
• Strong background in *automation, scripting, and tooling* (Bash; you will be writing lots of code in this role)
• Excellent ability to *diagnose and resolve complex system, scaling, or performance issues*
• Self-starter mindset with the ability to balance *technical depth, team leadership, and strategic impact*
• Experience in Web3 or high-growth startups, a plus
• Excellent written and verbal communication (we’re serious)
• Comfortable working autonomously and asynchronously within a distributed team.
• Located in or able to work within GMT to EST time zones.

*Our Stack:*

• Typescript and C++
• LMDB for persistence
• Discv5 and libp2p
• Ethereum as L1
• Terraform
• OpenTelemetry
• Grafana
• GCP
• AWS
• K8s

What We Offer:

• Flexible, remote-first culture with HQ in London.
• Competitive salary + equity/token options.
• 25 days annual leave + bank holidays.
• Health, dental, and retirement benefits (based on location).
• Regular offsites for team collaboration and bonding.
• Conference and learning budget for continual professional development.
