We acquire, analyze, and deliver insights in smart, scalable ways that help organizations identify and mitigate risk.

• Have founded or held early roles at successful fast-paced startups
• 6+ years of full stack software development experience
• Advanced knowledge in Ruby (Ruby on Rails)/ Javascript (React), or similar languages/frameworks

• Experimentation mindset - autonomy and empowerment to validate a customer need, get team buy-in, and ship a rapid MVP
• Experience building scalable technical architecture that can scale to 10mm+ users (including observability tooling, container orchestration, etc)

Nice to have:

• Experience with trust & safety, IDV, background check products or criminal data
• Experience with data analysis and processing
• Experience building and working with scrapers and scraping technology

We are committed to leveling the playing field and welcome all interested candidates to apply, even if you don’t meet every qualification outlined above.

What you get:

• Learning and development allowance
• Competitive compensation and opportunity for advancement
• 100% medical, dental, and vision coverage
• Up to 25K reimbursement for fertility, adoption, and parental planning services
