Job Description

3Play Media is the leading provider of superior quality captions and interactive transcripts for publishers of digital media, including educational institutions, online media and eLearning providers, government agencies and the entertainment industry. Our unique process begins with automatic transcription and natural language processing to produce a draft transcript. Human experts then edit the draft, using our proprietary platform, which is optimized for cleaning up the machine output. Our large and growing database of audio and time-coded transcription provides a fertile basis for continually improving our product.

3Play seeks a dedicated, creative, adaptable, hands-on R&D engineer who will contribute to all aspects of product development, with special focus on applying machine learning and natural language processing technologies to large databases to improve our automated transcriptions, our operations, and our end-user products. In addition to familiarity with modeling and algorithms, this individual will need to employ rigorous scientific methodology to improve machine performance on real-world data, and will use clear and timely written communication to specify development plans and report on progress. Further, this job requires the coding and development skills to deploy these improvements in production, working with a small, collegial, agile, and results-oriented team.

While we emphasize ability – not credentials – the following attributes would likely benefit someone in this role:

  • Bachelor’s degree in a STEM field
  • Web software development experience
  • A record of contribution in NLP, machine learning, DSP or related areas
  • Knowledge of – or eagerness to learn – Ruby on Rails
  • Excellent written and oral communication skills

About the Company

3Play Media is a rapidly growing, profitable start-up making a genuine impact on the way people consume online media. We help make video and audio accessible to everyone, and are focused on continually improving our customers’ experience. Since we got our start in 2007 out of MIT Sloan, we have been simplifying the typical transcription workflow through flexible APIs, a secure online account system, and integrations with players, platforms, and lecture capture systems. Our operational infrastructure is designed to maximize transcription throughput and quality at a fair price. We are constantly looking to incorporate new technologies into our system to improve these capabilities.

Work Environment

We love our company culture! We are currently a small team of seven developers working closely with each other and with others in the office, with no interest in drama or office politics. We have a spacious office with lots of natural light, a game room with beer and kombucha on tap, and a friendly dog named Bo who shares our views and ambitions (but not our interest in math jokes or riddles — no one’s perfect!). We’ve all made good friends within 3Play, and also enjoy 3Play hosted events including Summer retreats and game nights.


Boston, MA – Fort Point on the Red Line near South Station, in the heart of Boston’s thriving Innovation District at the Boston Seaport. Surrounded by Boston’s buzzing tech scene, we are minutes from food truck hotspots, Chinatown, and Downtown Crossing, and new restaurants and bars are popping up regularly next to older favorites.

Insider's spotlight

What are some social events your company does?

I collaborate with my colleague Lily on a wide range of social events for 3Play Media. Our goal is to create a diverse amount of social gatherings, month-to-month, that every employee can enjoy. Recently we held a murder mystery night where everybody was assigned a role and our task was to find the "murderer." We have also enjoyed bowling, a Red Sox game, scavenger hunts around the Seaport District, and game nights in the office. Beyond formal social events, everyone in the office is always open to going out after work for appetizers or casual drinks. It's a great environment to grow and have fun as a team!


Account Manager

How do you collaborate with other teams in the company?

There is an open and collaborative philosophy that is instilled in each employee from the executive team, even before a person is hired. The executive team fosters a true "open door" policy by always being available in person to field questions or hear ideas.

The sales, marketing, account management, research, development, and support teams meet twice a month to discuss any blockers or support trends, as well as current customer-facing development and new product development and research.


Account Executive

How has your career grown since starting at the company?

My experience at 3Play has been a whirlwind! I was hired to produce and manage content 3.5 years ago; after about a year, I was managing more marketing programs, and another year later, I became the Director of Marketing.

I think my experience is a testament to how the exec team feels about promoting internally, and I am so grateful. I feel respected and valued every day. 3Play has fostered my growth and my work, and now I have the privilege of leading a team and strategizing ways to help grow a company and product that I'm truly passionate about.


Director of Marketing

We are at the forefront of making video the ultimate tool for learning, communication, and entertainment. One day, every video (created by an established organization) will be transcribed, captioned, and/or described. It may be for accessibility requirements; it may be because people start to recognize the many additional benefits because of search and navigation, or because they want to watch videos on social networks while standing in line. Whatever the reason, there is a massive amount of content that will have a text equivalent to enhance the user experience. This presents exciting and daunting operational challenges; challenges that we are taking on with full steam to be the unequivocal leader in the space and to offer the ultimate solution for accessible and consumable video.
