Since 2011, the New York, Boston, and Philadelphia Scala meetups have hosted this community-driven Scala conference. Because the Northeast Scala Symposium (NEScala, to its friends) is community-driven, you help create it. The NEScala talks are proposed by the attendees , who then vote to select which will be given.

For the fourth year in row, NEScala coincides with the Typelevel Summit.

This year, we're back in Philadelphia, at the Science History Institute in Old City, April 1st through 3rd. (For the first time, all three days of the combined conference will occur on weekdays. Come early, and spend the weekend touring historic Philadelphia.)

  • Monday, April 1, is the Typelevel Summit.
  • Tuesday, April 2, is the Northeast Scala Symposium.
  • Wednesday, April 3, is the combined Unconference.


This year's event is at the Science History Institute  , 315 Chestnut Street, Philadelphia, PA 19106.

There are numerous hotels within walking distance of the venue. Use the Google Maps link, above, to locate nearby hotels.

The Science History Institute collects and shares the stories of innovators and of discoveries that shape our lives, preserving and interpreting the history of chemistry, chemical engineering, and the life sciences. Headquartered in Philadelphia, with offices in California and Europe, the Institute houses an archive and a library for historians and researchers, a fellowship program for visiting scholars from around the globe, a community of researchers who examine historical and contemporary issues, an acclaimed museum that is free and open to the public, and a state-of-the-art conference center.


Once we've finalized the talks, we'll update this page with the full schedule.


To secure your spot for both the Typelevel Summit and NEScala, you need to purchase just one $75 ticket. Get your tickets at Tito.

Diversity Conversation & Lunch

We're excited to announce the first-ever NEScala+Typelevel Diversity Lunch. The lunch is sponsored by and will be held at 12:30pm on Tuesday, April 2nd, at:

217-219 Chestnut Street
Philadelphia, PA 19106.

You can RSVP, below.

The lunch is a conversation that brings together a diverse group of people to discuss navigating traditionally homogenous industries like technology and finance. In particular, we'll discuss how to

  1. bring your full self to the workplace
  2. present different viewpoints effectively

We’ll have a few conversation starters on these topics, but we mostly want to create a safe space and promote authentic dialogue in a small group setting over great food. All are welcome to participate. The only requirement is you must act in accordance with our Code of Conduct. This means contributing to a respectful and safe environment that enables the group to discuss and problem solve potentially hard topics.  We welcome all voices to the table and are committed to creating an environment that allows them to be heard.

To reserve your place at the table, please RSVP at .

Code of Conduct

The Northeast Scala Symposium is committed to providing an environment that encourages and empowers its members to teach, learn, and collaborate. We welcome every skill level – from beginners to experts – to participate and advance the Scala community.

Importantly, our members represent multiple dimensions of difference – across gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, race, religion, and more – and we want everyone to feel comfortable bringing their full selves to the conference.

This means all members should apply a high degree of care and consideration to how they interact with others. We do not tolerate harassment in any form, but also want to go even further in actively creating an environment of belonging, inclusion, safety. Anyone acting contrary to the spirit of this mission will be asked to leave the conference at the discretion of the organizers.

The day of the conference, we will have a telephone hotline and a Slack channel (or similar mechanism) available for instant and anonymous feedback. The details on how to access those resources will be posted here. If at any point during the conference you experience an issue in this regard, we encourage you to use the hotline. If you have less urgent feedback, you are welcome to post it (again, anonymously) to the Slack channel.

The organizers have developed a formal set of procedures for handling complaints, including a chain of escalation.
