$1 trillion is lost to scams annually, with 98% of cybercrime exploiting human psychology. We are on a mission to protect people from scams. We are looking for a Senior Full Stack Engineer to join our team and build a platform of AI-powered embedded tools that help stop scams before they happen.
What You Will Do:
Build it all and run it all: Greenfield project. You’ll own the frontend, backend, and early infrastructure.
Design the architecture: You’ll have a significant impact on shaping the system—tools, patterns, and infrastructure. Collaborate with the team to define what “great” looks like and help steer the direction of the architecture.
Think like a founder: We’ll rely on you to help us hire, scale, and make the right decisions.
Be a team player: We are a lean team of visionaries and operators. Collaborate with us to bring our vision to life.
What We Are Looking For:
You’ve built and shipped full-stack apps (React, Next.js, TypeScript, or other technologies).
You’re curious about emerging technologies.
You thrive in fast-moving, ambiguous environments.
You have experience in startups and scale-ups.
You enjoy solving deep technical problems with customer experience in mind.
You can evaluate and make decisions based on a balanced assessment of key factors, including design, innovation, technical debt, cost efficiency, and scalability.
