Full-time
About Callisto:

Callisto is a San Francisco-based nonprofit organization that creates technology to combat sexual assault, empower survivors, and advance justice. Specifically, we create websites that make it easier for sexual assault survivors to report and name their assailant and enable the detection of repeat sexual offenders. We also connect survivors to attorneys who advise them on their options to seek justice. We are funded by earned revenue from partner institutions and by philanthropic supporters, including Google.org, Y Combinator, Greylock Partners, and the Skoll Foundation.

We are a rapidly growing and powerful team, united in the belief that we can create a more safe and just world.

About the Position:

As the Senior Backend Software Engineer at Callisto, you will join a fast-paced, collaborative, multidisciplinary team to implement and support first-class technical infrastructure in solving complex problems in the social justice, data security, and legal space. Our Product Team is passionate about building and scaling our survivor-centered products as we grow.

With your versatile engineering experience and strong technical background, you will immediately be able to join us in sustaining our ability to support even more users and survivors. To do this work we bring high attention to detail to everything we do, from bug-fixing to code climate improvement (documentation, automated tests, and analytics) to new feature development. Problem-solving will be at the heart of what you do.

While at times you will work independently, we also highly value collaboration and communication within the team and with other departments; you will participate in our stand-ups, user-centric product design, QA work, and project management. Over time, you will contribute meaningfully to our developer operations and develop a strong understanding of the sexual assault and coercion space, with a focus on user privacy and security.
We are excited to deepen our expertise in innovative approaches to product development and to scale our engineering processes while adopting industry best practices. We hope you are as excited to learn new things and will consider applying for this role if this sounds like you.

This position will be located in San Francisco.
