About Status

Status is building the tools and infrastructure for the advancement of a secure, private, and open web3.

With the high level goals of preserving the right to privacy, mitigating the risk of censorship, and promoting economic trade in a transparent, open manner, Status is building a community where anyone is welcome to join and contribute.

As an organization, Status seeks to push the web3 ecosystem forward through research, creation of developer tools, and support of the open source community.

As a product, Status is an open source, Ethereum-based app that gives users the power to chat, transact, and access a revolutionary world of DApps on the decentralized web. But Status is also building foundational infrastructure for the whole Ethereum ecosystem, including the Nimbus ETH 1.0 and 2.0 clients, the Keycard hardware wallet, and the Waku messaging protocol; the p2p communication layer for Web3.

As a team, Status has been completely distributed since inception. Our team is currently 200+ core contributors strong, and welcomes a growing number of community members from all walks of life, scattered all around the globe.

We care deeply about open source, and our organizational structure has minimal hierarchy and no fixed work hours. We believe in working with a high degree of autonomy while supporting the organization's priorities.

About Waku

We are building Waku as a public good infrastructure. Waku is uncompromising Web3 communication at scale. It is a decentralized, censorship-resistant, privacy-preserving communication network that enables anyone to send and receive messages without worrying about surveillance or deplatforming.

We are enabling Ethereum builders to create new projects with a fully decentralized architecture, think dApp to Wallet notifications, NFT marketplaces, censorship-resistant chat, layer-2 and more.

Waku enables a variety of complex use cases and applications. To facilitate the adoption of Waku, you will design and implement application protocols to provide to dapp developers as off-the-shelf SDKs.

https://waku.org/

Key responsibilities:

  • Design and implement network simulation tools and solutions to validate the functionality and performance of distributed systems.
  • Run, analyze, and report on small-scale simulations to test the behavior of a specific protocol change or software implementation, or to simulate a type of attack on the Waku clients.
  • Own, maintain and improve the waku-simulator framework to enable running local simulations of the Waku network.
  • Work closely with Waku engineers and researchers to help design and analyze simulations needed to validate assumptions.
  • Assist engineers by conducting ad-hoc regression testing, reproducing bugs, and testing bug fixes.
  • Be the point of contact within the Waku team for the the Vac/DST (Distributed System Test) Team who is in charge of large scale simulations and QA activities.
  • Pre-empt and plan small scale simulations to study the behaviour of Waku clients, identify potential bottlenecks and performance optimization, then handover to DST for large scale simulation to confirm findings.
  • Foresee, and help plan and execute any other testing activities that helps ensure the production readiness of Waku, including secure scaling.
  • Help provide visibility on testing and simulation output, to ensure that the wider Waku ecosystem is informed of the expected performance of the Waku protocol and software.

You ideally will have:

  • A passion for blockchain technology, privacy-preserving technology and decentralization.
  • Solid experience with scripting languages (Python, Shell) and a systems language like Rust, C++, Nim, Go.
  • Strong foundation in networks and system programming.
  • Working knowledge of Docker and POSIX-like systems.
  • Algorithm design skills.
  • Have a strong alignment to our principles: https://status.app/manifesto

Hiring process:

  • Call with Talent.
  • Interview with Waku Research team member or lead.
  • Take home task (paid).
  • Interview with another Waku Research team member or Lead to present home task and discuss further.
  • Interview with Waku lead.

Compensation:

We are happy to pay in any mix of fiat/crypto.

What is the meaning of Layer 2?

Layer 2 in the context of cryptocurrency and blockchain technology refers to a secondary framework or protocol that is built on top of an existing blockchain system (the main chain or Layer 1)

The primary purpose of Layer 2 solutions is to solve the scalability and speed issues that many blockchains face, especially those that have become popular and heavily used, like Ethereum

Here are the key aspects of Layer 2 solutions:

  1. Scalability Enhancement: They help in scaling the main blockchain by handling transactions off the main chain. This reduces the burden on the main chain, allowing for faster and cheaper transactions.
  2. Types of Layer 2 Solutions: There are various forms of Layer 2 solutions, including state channels, sidechains, plasma chains, and rollups. Each has its own mechanism for interacting with the main chain and handling transactions.
  3. State Channels: These involve two parties engaging in numerous transactions outside of the main chain, which are then consolidated into a single transaction. This is especially useful for situations where multiple transactions occur between the same parties.
  4. Sidechains: These are separate blockchains that are connected to the main chain via a two-way peg. They operate independently and can have their own consensus mechanisms but are secured by the main chain.
  5. Plasma Chains: Plasma chains are similar to sidechains but with a more hierarchical structure. They report back to the main chain regularly and are optimized for mass transaction handling.
  6. Rollups: Rollups process and store transaction data on a sidechain but post transaction data to the main chain. They come in two varieties: optimistic rollups and zk-rollups, each with its own method of transaction verification.
  7. Security Considerations: While Layer 2 solutions are generally secure, they can have different security models compared to the main chain. This is an important consideration for users and developers.
  8. Impact on User Experience: For end-users, Layer 2 solutions can greatly improve the experience by reducing transaction fees and increasing transaction speeds.
  9. Adoption and Development: Many blockchain projects are actively developing Layer 2 solutions to enhance their networks. This is an ongoing area of innovation in the blockchain space.
