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.

Director of Research and Evaluation

About Callisto:

Callisto is a nonprofit tech startup that has created an online sexual assault reporting system. Sexual assault survivors can use our websites to (1) learn information about sexual assault reporting policies and resources in their area, (2) save a time-stamped written record of what happened to them, (3) report their assault electronically to the authorities or a legal advisor, or (4) report their assault if someone else names the same assailant. The system launched 2 years ago on 2 pilot college campuses, and has since grown to 12 colleges. In the next year, we plan to grow to 25 colleges and start a non-college pilot.

The Director of Research and Evaluation will oversee the evaluation strategy and execution for the organization. You will:

  • Lead our overarching evaluation strategy
  • Design and execute in-house research projects such as surveys, focus groups, and interviews to evaluate our effectiveness, identify opportunities to improve, and explore business challenges
  • Identify and work with external evaluators to co-apply for grants, design research studies, and publish evaluation results
  • Ensure that data are collected and shared in an ethical manner that is respectful of the privacy of our users and institutional partners

You are:

  • An analytical and creative thinker
  • An independent problem-solver and identifier
  • A strong communicator who can speak about data through both numbers and story
  • Willing to pitch-in as needed at a startup where you will be the first research hire

You have:

  • Worked 3+ years in study design, qualitative data analysis, and quantitative data analysis
  • Completed a PhD or equivalent in a relevant field
  • Published peer-reviewed articles on program evaluation
  • Ideally, studied sexual assault and/or harassment

To Apply: Please send CV and Cover letter to [email protected] We encourage you to apply in a timely manner as applications will be reviewed on a rolling basis.


  • Cover Letter should express why you want to join the Callisto team and how you are a strong candidate for this role.
  • The ideal start date for this position is by the end of September 2017.
  • Candidates should be based in or able to relocate to San Francisco, and willing to travel as needed.

Compensation is commensurate with experience. Callisto provides generous health, vision, and dental insurance, and a professional development budget to all team members.

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.

Front-end Engineering Contractor

About 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 current front-end stack is SCSS compiled with python, bootstrap, and a few small JS libraries. The front-end is being completely redone so you’ll have your choice of asset pipeline, compilers, front-end framework, etc. The only requirements are that your end product should be in SASS or SCSS and maintain our JS libraries functionality.

About the Gig:

In the next two months, we will be implementing a redesign of Callisto (demo here of current version). We’re looking for a front-end engineer for a two month contract, starting ASAP, to work alongside our product designer and full-stack dev to implement this redesign from InVision prototypes. They should be based in the US and available to work between 10am - 5pm PT on weekdays.

This contract position is expected to last 2 months. We anticipate needing 30-40 hours/week for the first month (implementing the redesign) and 20 hours/week for the second month (design QA and cleanup). Compensation is competitive and commensurate with experience.


  • Can work closely with a product designer
  • Highly communicative, high-touch, highly iterative
  • Strong work ethic, attention to detail, and drive
  • Familiar with Slack, Github, Confluence, Hangouts, and all the modern communication tools necessary to keep a team in tune and on time with deployments
  • Process-oriented with ability to work with a UI kit and rapid prototyping (InVision)
  • Experience working in a front-end HTML template engine commonly shipped with back-end frameworks (Jinja, Django Templates, Haml, ERB, etc)
  • Proficient understanding of cross-browser compatibility issues and ways to work around such issues
  • Knowledge of web content accessibility standards
  • Basic knowledge of image authoring tools, to be able to crop, resize, or perform small adjustments on an image or SVG. Familiarity with tools such as as illustrator or Photoshop is a plus
  • Experience with JS testing libraries (Jasmine, QUnit) is a plus

To Apply: Please send Resume/CV and Portfolio (Git[hub/lab], etc) to [email protected] with the subject line "Front-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.
