Technical Evangelist (Boston or New York)

| Greater Boston Area
Boston, USA
Circle is a global internet finance company, built on blockchain technology, powered by crypto assets, and dedicated to helping people everywhere create and share value.
We’ve already made sending money around the world free and easy using blockchain technology with Circle Pay. With Circle Invest, we’re expanding our offerings with a cryptocurrency investment product, enabling anyone to buy and sell crypto assets. Through Circle Trade, we’re market makers for the top crypto coins and offer OTC trading services. In March 2018, Circle acquired Poloniex, one of the world's leading token marketplaces.
Circle is thrilled to announce this critical new opening on our fast-growing team. In this role, you will vet the quality of token projects with a specific focus on their implementation and evaluate the long term viability of the project including its choice of platform, stability, speed, cost, ability to scale to exchange-level transaction volume, documentation, level of development activity, quality of testing and openness to audits. You will also help devise qualitative and quantitative metrics for token assessment, including scalable methods for judging code quality (e.g. automated git reputation scoring or similarly themed methods) to judge a project’s future stability and promise. Given the evolving nature of the crypto ecosystem, the ideal candidate will also assist in the ongoing design and optimization of this role and how we, as a company, select tokens for our platforms

What you'll work on

  • Vet the quality of token projects, with a specific focus on their implementation
  • Evaluate the long term viability of the project, including its choice of platform, stability, speed, cost, ability to scale to exchange-level transaction volume, documentation, level of development activity, quality of testing and openness to audits
  • Assess the robustness of the team’s attention to detecting and preventing fraudulent activity
  • Gauge the quality of each project’s engineering team in terms of its background as well as accessibility and willingness to address issues and need for ongoing support
  • Help devise qualitative and quantitative metrics for token assessment, including scalable methods for judging code quality, e.g. automated git reputation scoring or similarly themed methods to judge a project’s future stability and promise
  • Present our internal engineering team with a thorough assessment of the quality of the project, its tech, the strength and scalability of its wallet architecture, vulnerability to fraud, and so on.
  • Contribute to non-digital asset business development work on an as-needed basis; for more conventional business development projects that require technical vetting, help evaluate quality of partner APIs, guide partners on the use of our API, evaluate technical robustness of partners’ platforms, and the like

What you'll bring to Circle

  • Experience coding or in business environments in which you have developed a keen and trusted ability to judge the quality of a project’s code
  • A strong reputation in the crypto developer ecosystem such that innovators will want to impress you with the idea behind, and quality of, their projects. The ideal candidate will possess such a reputation because of having been a creator of or contributor to existing or past projects.
  • A track record of speaking to a variety of audiences - both evangelizing in public and engaging internal technical teams
  • An innate desire to research and learn and an ongoing voracious curiosity to read token project white papers.
  • The ability to analyze and synthesize data to develop hypotheses about the viability of a given project and to help make decisions about Circle’s future relationship with that project
  • A history of maintaining a clear list of, and adhering to, priorities. This is essential given the volume of “noise” from inbound global interest of projects that wish to be listed on Circle platforms
  • An inherent desire to work and collaborate with others, both internally and externally
  • Can toggle between working with outside developers as well as institutional investors, as needed as this role evolves.


  • Undergraduate degree required, graduate degree preferred but not necessary
  • 5+ years of experience, at least 2 of which has been spent mediating between outside parties and internal constituents to get things done
  • Strong interpersonal skills
  • Ability to manage complex projects and multi-task with excellent organization skills
  • Comfort with a fast-paced environment and changing requirements
  • Ability to flourish with minimal guidance, be proactive, and handle uncertainty and ambiguity
  • Analogous experience that involved the kind of research this role will require with respect to reading and digesting project whitepapers 

Circle was founded in 2013 by internet entrepreneurs Jeremy Allaire and Sean Neville. We’re backed by $250 million from investors including Jim Breyer (Facebook), Goldman Sachs, IDG Capital (Baidu, Tencent), General Catalyst (AirBnB, Snapchat), Accel Partners, and Bitmain, with offices in Boston, New York, San Francisco, Dublin, London and Hong Kong.

Insider's spotlight

What’s the vibe like in the office?

We have a team-oriented, open concept, collaborative office. I love working with people who are incredibly passionate about what they do.


Office Experience Coordinator

How do you collaborate with other teams in the company?

If I can, I walk over to them, but I typically message them on Slack about an idea or contextualized piece of customer feedback. With that info, we can better understand how to enhance overall customer experience and how we can improve it.


Customer Experience Specialist

How has your career grown since starting at the company?

Coming to Circle from a law firm was a huge change for me, but I’ve learned so much in just a few months. From learning about cryptocurrency to employment law to stock options, I love that I get to work on something new every day. I’m excited to continue working for a company that gives me an opportunity to learn something new every day.



What's the biggest problem your team is solving?

Circle has been an ideal place for to gain technical knowledge from pros with deep expertise in their fields. Working alongside seasoned engineers and data scientists, a younger professional can learn the ins-and-outs of complex frameworks that would take years to master elsewhere. Circle has taken my technical skills to the next level.
