About Us

We’re TWO-N, an award-winning boutique data visualization agency. We are small and nimble by design, allowing us to respond to unique and changing client needs. We get called upon by companies to design and build innovative user interfaces with visualizations that graphically present information functionally and beautifully. We build robust end to end solutions for clients in many industries. Our projects typically take the form of custom web applications, Our design sensibility is one of our main differentiators, and we equally embrace technical challenges.

By nature of being a boutique agency, no two projects are the same. We operate as a studio, which means we all contribute to the various components of completing a project, including brainstorming, design, and development. Our small team is flexible and collaborative.

Some examples of projects we’ve worked on include:

Designing and implementing financial tools for companies like WisdomTree, Franklin Templeton Investments, Fidelity, Northern Trust, Bloomberg

Making maps of data on many topics, from politics to the environment. (NBC Elections Map, NBC Plan Your Vaccine, LGBTQ Demographics, Ocean Plastics)

Communicating internal insights to executives within an organization or their clients. (MRP Tool, Live Nation Fan Journey)

Communicating results, products, or data collection to the public (The Trevor Project Mental Health Survey, Adolescent Data Hub)

Creating visual dashboards on subjects ranging from health to finance. (AMA Dashboard, Level ETF)

Job Description

We’re seeking someone who can help support our React projects as a front-end UI developer. We’re looking for developers who are excited to build user interfaces in a clean, scalable fashion in the browser.

In this role, you will be responsible for developing and implementing performant React + Typescript components, understanding and managing component state (locally or through Redux), and contributing to an entire web application architecture. You will not only be working on individual small components of the project, but should be comfortable learning and speaking to an entire application build.

Our primary goal is to inspire, delight, and inform others while continuously challenging ourselves. If that’s appealing to you, then do get in touch and include some links to what you’ve built.
