Our History

In November 2011, Callisto CEO Jess Ladd founded Sexual Health Innovations (SHI) while she was a graduate student at Johns Hopkins University. SHI was founded with the goal of creating technology to advance sexual health and wellbeing in the United States.

In 2014, SHI announced an initiative called Callisto at The White House Data Jam on Campus Sexual Assault.

A year-long pilot of Callisto launched in August 2015 at the University of San Francisco and Pomona College. Callisto’s successful pilot, growing demand for the system both within and outside of the college setting, and a growing national dialogue on campus sexual violence led SHI to decide in the summer of 2016 to reorganize and rebrand as Callisto. Today, Callisto is available at a growing number of colleges nationwide.

Back-end Engineering Contractor

About Callisto:

Callisto is a nonprofit dedicated to creating technology to combat sexual assault, empower survivors, and advance justice. We build an online sexual assault documentation and reporting system, and we partner with college campuses to provide school-customized Callisto websites for their students. We're launched on 8 campuses (the latest is Stanford) and will be in 12-15 in the fall. The most unique aspect of Callisto is our matching system that detects repeat offenders - allowing victims of the same perpetrator to "match" and report simultaneously. Here's a TED talk about how it works.

About the Tech:

Callisto’s stack is Python / Django / Postgres / Heroku. Significant portions of Callisto’s functionality are contained within its open source repos (callisto-core, django-wizard-builder). The Callisto codebase is two and a half years old, and in the last few months we’ve been transitioning to a new dev team to maintain it.

About the Gig:

In the next 3 months, we’ll be maintaining Callisto at our current 8 campuses, launch at 4-7 additional campuses, complete a security audit (we work with an external firm - NCC Group) and fix any issues they flag, and implement a new design (mostly front-end work but a little bit of moving around the user flow).
We're looking for an Python / Django contractor experienced in DevOps and SQL databases to help out for 2-4 months, likely at 20-40 hours per week. We're looking for you to start immediately. Ideally, you'd be located in Portland (alongside our full-stack engineer), although we’re also interested in speaking with candidates who could work remote from somewhere else in the U.S. You should have some background working with secure systems (the data in Callisto is very sensitive, as you might imagine). Compensation is competitive and commensurate with experience.

To Apply: Please send Resume/CV and Portfolio (Git[hub/lab], etc) to [email protected] with the subject line "Back-End Engineer Contractor." We encourage you to apply in a timely manner as applications will be reviewed on a rolling basis.

We are an equal opportunity employer and value diversity at our organization. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
