Staff Full Stack Software Engineer

About the role

Binti builds software for state and county government agencies, focusing on reinventing social services. We started in child welfare, with the mission of helping every child have a safe, loving, and stable family. To date, we’ve helped approve more than 100,000 families to foster or adopt, and we support over 49% of the nation’s child welfare system. We have expanded our product offerings in child welfare, moving more to the root of the problem, helping families stay together and avoid separation, and are now expanding horizontally across other areas in social services.

Binti is a for-profit, mission-driven software company based in San Francisco, CA. Investors include Founders Fund, First Round Capital, Kapor Capital, and others. We’re a team of ~90 people and growing quickly. We care about creating a workplace where everyone feels welcome and can bring their full self to work. We have a huge, ambitious vision to rewire government to be more effective in expanding opportunities for people around the world, and we are looking for mission-driven, high-empathy, high-performance, and low-ego team members to join us on our exciting journey towards that vision.

- Identify and resolve systemic risks — including security, HIPAA compliance, performance bottlenecks, and incident response — before they become problems

- Raise the technical ceiling for the whole engineering org through code review, design critique, and modeling excellent judgment

- Proactively leverage AI and modern tooling to drive higher output quality and team efficiency
