Engineer (Full Stack, AI Company)

The client is on a mission to make the internet more human, all in the palm of your hand. Combining proprietary palm biometrics with agent verification, the client powers secure and seamless digital experiences across social, fintech, and crypto platforms through a hardware-free palm scan that works on any smartphone.

Built for an era of AI deepfakes and digital spoofing, the client delivers fraud-resistant verification with privacy at its core. The platform enables organizations to confirm real users without compromising personal data. Developed by experts in biometrics, crypto, and AI, the client is designed to meet the growing need for trust in an increasingly digital world.

The client is looking for a Full Stack Engineer to build the systems behind the product. You will design and ship the backend and frontend that power hardware-free verification at scale, working directly with the founding team before a formal engineering function exists. Strong candidates are pragmatic builders who care about performance, security, and shipping fast in an early-stage environment. The team builds with AI, not around it: using AI coding tools every day. Judgment in reviewing what these tools produce matters as much as the speed they provide — in a fraud and biometrics product, knowing when the model is wrong is the job.

• →Design, build, and maintain backend services and APIs that power the verification platform.
• →Build front-end experiences and integrate them cleanly with backend systems.
• →Ship scalable, secure, cloud-based infrastructure across the stack.
• →Work directly with product and the founding team to turn ideas into shipped features quickly.
• →Optimize, troubleshoot, and harden existing code as the product grows.

• 3+ years building production software as a full stack or backend engineer.
• Strong foundation in software development, OOP, database design, and API development.
• Proficiency in Go and TypeScript (backend is Go, web stack is React/Next.js), with comfort across front-end/back-end. Python a plus.
• Fluency with AI-assisted development — daily use of tools, with clear judgment on where they help/don't and how to critically review AI-generated code.
• Experience with scalable, cloud-based applications.
• Strong problem-solving skills; thrives in a collaborative, early-stage team.

• Experience with AI, biometrics, privacy, or security-sensitive systems.
• A track record shipping products from zero to one without a defined playbook.
• Hands-on experience with agentic/autonomous coding tools beyond mainstream assistants.
• Familiarity with crypto, identity, or digital trust as a product category.
• Remote, US-based only (SF, NYC, Miami preferred).
