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.
What You’ll Do
We’re looking for entrepreneurial, impact-driven engineers who thrive in fast-paced environments and want to be at the forefront of privacy-first decentralized applications. You’ll be part of a highly collaborative team working on the client-side stack that powers Aztec's zero-knowledge execution environment.
You Will

  • Design and build tools & SDKs that enable developers to build powerful, privacy-preserving dApps on Aztec.
  • Develop a secure client-side execution environment, used by wallets and applications to produce and handle encrypted transactions.
  • Architect reusable patterns and libraries for writing auditable and verifiable Aztec smart contracts.
  • Collaborate cross-functionally with protocol, cryptography, and product teams to build end-to-end privacy-preserving applications.
  • Refactor, document, and test existing code for maintainability, performance, and correctness.
  • Identify and reduce technical debt, while continuously improving architecture and developer ergonomics.
What We’re Looking For
  • 3+ years of professional software engineering experience, ideally in blockchain or cryptography-related systems.
  • Deep proficiency in TypeScript, with strong software architecture and API design skills.
  • Working knowledge of system-level concerns such as performance tuning, memory management, and secure data handling.
  • Able to provide thoughtful code reviews and mentor other engineers.
  • Comfortable working autonomously and asynchronously within a distributed team.
  • Located in or able to work within GMT to EST time zones.
Bonus Points
  • Experience with Rust, Solidity, or other smart contract languages.
  • Contributions to open source projects, especially in the Web3 or cryptography space.
  • Familiarity with zk systems like ZCash or other privacy-preserving protocols.
  • Exposure to modern web development frameworks and tooling.
  • Passion for zero-knowledge cryptography and its role in reshaping the internet.
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).
  • Quarterly offsites for team collaboration and bonding.
  • Conference and learning budget for continual professional development.
  • A chance to work on truly cutting-edge zero-knowledge infrastructure with some of the best minds in the field.
Aztec Labs is an equal opportunity employer and we value creativity, diversity, and intellectual curiosity. If you're passionate about leveraging your creative talents to make a real-world impact, and if you want to be part of a team that's shaping the future of digital privacy, then we would love to hear from you.

Ready to be pushed beyond what you think you’re capable of?

At Coinbase, our mission is to increase economic freedom in the world. It’s a massive, ambitious opportunity that demands the best of us, every day, as we build the emerging onchain platform — and with it, the future global financial system.

To achieve our mission, we’re seeking a very specific candidate. We want someone who is passionate about our mission and who believes in the power of crypto and blockchain technology to update the financial system. We want someone who is eager to leave their mark on the world, who relishes the pressure and privilege of working with high caliber colleagues, and who actively seeks feedback to keep leveling up.

Our work culture is intense and isn’t for everyone. But if you want to build the future alongside others who excel in their disciplines and expect the same from you, there’s no better place to be.

While many roles at Coinbase are remote-first, we are not remote-only. In-person participation is required throughout the year. Team and company-wide offsites are held multiple times annually to foster collaboration, connection, and alignment. Attendance is expected and fully supported.

The Coinbase Developer Platform APIs are the easiest way for developers to get started with building crypto applications. Conceived by Coinbase CEO Brian Armstrong, these APIs enable those with no prior knowledge of crypto to begin sending and receiving crypto in as little as 30 seconds. A top priority of the Coinbase Developer Platform (CDP), the CDP APIs encapsulate some of the most cutting-edge technologies in crypto by externalizing Coinbase’s internal services, built over more than a decade of experience. The CDP APIs combine custodial and non-custodial wallets into one clean abstraction, making interactions with the blockchain simple and painless.

The CDP API team owns both server-side APIs and client-side libraries across different languages. The team seeks a full-stack engineer who is passionate about all aspects of excellent developer experiences: authoring clear and informative documentation, building compelling sample applications, interacting directly with customers to incorporate feedback, architecting delightfully simple SDKs, etc. The engineer must be comfortable operating in both frontend and backend codebases, fluent across a variety of programming languages, and demonstrate both high code velocity and quality simultaneously. The CDP API team consists of some of the most prolific and tenured software engineers at Coinbase, and is excited to ship a game-changing set of APIs and SDKs at breakneck speed.

What you’ll be doing:

  • Design, develop, and maintain scalable, secure, and high-performance backend systems for the CDP APIs using Go and Javascript
  • Define and maintain clean and conformant HTTP REST API definitions using OpenAPI specifications
  • Design, develop, and maintain ergonomic, open-source SDKs to interact with the CDP APIs using Ruby, Typescript, Go, Python, and Java
  • Author, publish, and maintain clear and concise documentation, including quickstart and how-to guides, to increase adoption of the Platform APIs and SDKs
  • Develop secure and scalable key management systems, packaged as Docker images, to enable crypto wallet functionality across a range of custodial configurations (e.g. self-custodial MPC)
  • Work closely with many different teams at Coinbase to externalize their backend services through the Platform APIs, ensuring consistency of concepts, >
  • Interface directly with customers to collect their feedback and iteratively improve the CDP APIs and SDKs
  • Build compelling sample applications end-to-end using the CDP APIs and SDKs to demonstrate their value and pressure-test the developer experience
  • Troubleshoot and debug complex fullstack issues, ensuring stability, reliability, and security
  • Participate in code reviews and provide constructive feedback to maintain high code quality standards

What we look for in you:

  • 5+ years of experience in both backend and frontend software development
  • Mastery of Go and JavaScript; experience with Ruby, TypeScript, Python, and Java is a plus
  • Excellent verbal and written communication skills, with an eye for detail and a passion for clear, comprehensive developer documentation
  • Strong understanding of crypto wallets, including key management, cryptography, and blockchain protocols (e.g. EVM)
  • Proven track record of designing, developing, and shipping high-quality, ergonomic client-side libraries and SDKs
  • Strong understanding of distributed systems, microservices architecture, and event-driven architectures
  • Experience with databases (PostgreSQL, MySQL, MongoDB) and caching systems (Redis, Memcached)
  • Solid knowledge of RESTful API design principles and experience with API development and integration
  • Familiarity with AWS and containerization technologies like Kubernetes
  • Understanding of security best practices and experience with implementing secure coding practices for financial systems
  • Crypto-forward experience, including familiarity with onchain activity such as interacting with Ethereum addresses, using ENS, and engaging with dApps or blockchain-based services.
