Software Engineer, Peer-to-Peer Networks

We seek an experienced software engineer to build the next generation of peer-to-peer networks. 
Engineering at Protocol Labs
Engineering at Protocol Labs is not just about writing world-class code. We create software systems that tackle significant challenges. We aim to solve those challenges with new technology breakthroughs and great user experience design.  We believe in an open-source approach to creation. We strike a balance between pragmatism (put it on a ship ⛴), deeply informed protocol design, and strict application of strong engineering principles. All of this happens in an environment defined by curiosity, passion, and a love for open source.

As a Peer-to-Peer Networking Engineer at Protocol Labs you might…

    • Build the next generation of peer-to-peer software, working on projects like libp2p, IPFS and Filecoin
    • Participate in the design and implementation of performant and resilient distributed applications
    • Create or maintain software libraries and programs depended on by other systems and applications
    • Integrate research results into real programs
    • Work alongside a cross-functional team including engineering, design, community, product, and business
    • Engage and educate the community, from users to contributors
    • Work on public open source repositories with broader communities

You may be a fit for this role if you have…

    • BA/BS degree in Computer Science, Computer Engineering, related field or equivalent practical experience 
    • Experience programming in one or more of the following: Go, Javascript, Rust, C, C++, Haskell, Ocaml, Python
    • Leadership experience building and maintaining large-scale distributed systems in production 
    • Significant experience building peer-to-peer applications 
    • Deep understanding of network protocols 
    • Excellent written and verbal communication skills 

Bonus Points

    • Experience leading and guiding Open Source projects 
    • Experience working with libp2p and/or IPFS 
What’s it like to work at Protocol Labs?
Protocol Labs mission is to improve humanity’s most important technology, the Internet. We build protocols, systems, and tools to improve how it works. Today, we are focused on how we store, locate, and move information. Our projects include IPFS, Filecoin, libp2p, and more.
As a distributed team, we hire anywhere in the world, and at various levels of experience (entry, senior, staff). We look for people with unique perspectives and diverse backgrounds.
We have a great benefits package, including parental leave, contributions to your retirement, competitive pay, and unlimited time off. For U.S.-based employees, we also provide platinum-level health, dental, and vision coverage for you and your family.

Back-End Engineer (Junior)

We are currently looking for a junior back-end engineer to add to our team. An ideal candidate would bring 1-5 years’ full-stack experience with a focus on back-end systems development — and a track record of employment, internship and/or open source contribution that demonstrates elite talent. You will work across our tech stack, contributing to everything from architecture to testing frameworks. You’ll be an integral member of our early engineering team, translating our roadmap into product features and open source contributions. 

We face many unique technical and design challenges as we build a new payment network. To that end, we have a pragmatic approach to the blockchain development environment: extend where falling short, fix where broken, and build where missing. Successful adoption for our product demands that we approach all aspects of development with a fundamental focus on security, reliability, upgradability and usability. We need engineers that are both disciplined and imaginative, who are driven by our vision and refuse to accept that any technical problem is impossible at first impression. We hope this is you!

Why this matters:

Our everyday payment systems are dependent upon financial infrastructure design decades ago. Consumers benefit from rewards programs and new checkout experiences, but in the background money moves the same as ever: through insecure networks that impose unnecessary costs on all of us as they strain to meet the needs of modern commerce.

 because we know that with the right product strategy, serving the right use cases, cryptocurrency and blockchain finally present a solution for many of our most persistent payment problems. It’s possible to rethink our current payment systems from the ground up. In doing that, we confront several difficult, challenging and impactful problems which will demand solutions in order to build a trusted and ubiquitous payment system to enable commerce for everyone. To achieve our mission and realize our vision, we’ve put together an incredible team and are selectively adding to it.

What you’ll do (outcomes)

  1. Write, test and audit applications and APIs to contribute to the Eco cryptocurrency implementation, manage blockchain settlement and support our launch partners.
  2. Compose existing and new solutions into a comprehensive tooling chain: build, packaging, unit testing, security fuzzing, coverage reporting, continuous deployment. We will publish and maintain this meta-package.
  3. Contribute to open-source community where existing productivity tools fall short. Maintain strong relationships with the relevant communities and projects.
  4. Work with platform and product engineers to understand deficiencies in tools and opportunities to improve them.
  5. Contribute to blog posts, meetups and workshop presentations promoting Eco’s contributions to the community.

What you’ll bring (core competencies)

  1. You’re comfortable working anywhere in the technology stack. You can develop back end applications, user interfaces, APIs, and smart contracts.
  2. You prioritize tests. You test your code as a matter of practice, and automate tests as part of getting the job done. You don’t consider code complete until there are automated tests demonstrating that it works.
  3. You thrive in a problem solving environment. You bring a pragmatic approach to solving problems; solving issues to unblock other developers without creating future maintenance problems. You’re persistent and not easily flustered when working with broken/buggy toolchains.
  4. You have an open source mindset. You have experience and presence in the open-source community; you have contributed to distributed projects. 
  5. You have strong CS fundamentals. You’re familiar with common algorithms and data structures, comfortable implementing new data structures where no suitable implementation already exists.
  6. You understand basic cryptography and security fundamentals. You have strong understanding of security and privacy.

Nice to Have

  1. 2+ years of full-stack experience as an engineer, with a provable track record of deploying code into production and contributing to the open source community.
  2. 1+ years of blockchain development experience.
  3. Familiarity with a variety of languages, particularly some combination of of:  Node.js, Go, C++, Python, Java, Solidity
  4. You understand the use cases of common cryptographic primitives and can design secure systems using them.
