Senior Software Engineer

We’re hiring a Senior Software Engineer to help architect, build, and scale the core infrastructure behind our AI-powered identity verification platform. This is a hands-on engineering role with significant ownership across backend systems, APIs, and product development.

What You’ll Do: Design, build, and own production backend services primarily using Golang. Take products and features from initial concept through development, deployment, monitoring, and scaling. Architect scalable APIs, data models, and cloud-based distributed systems. Build developer-facing APIs, integrations, and internal platform tooling. Work with TypeScript, React, and Next.js across the product when needed. Own database design, PostgreSQL schemas, migrations, and performance optimization. Leverage AI-assisted development tools to accelerate engineering while maintaining high code quality. Debug complex production issues using logs, metrics, distributed tracing, and source code. Collaborate directly with engineering leadership on architecture, security, and technical strategy.

5+ years of professional software engineering experience. Strong backend engineering experience with Golang or a comparable language such as Python, Java, or TypeScript. Proven experience building products from 0 1 and scaling production systems. Strong understanding of APIs, distributed systems, data modeling, and cloud infrastructure. Experience owning production services beyond initial deployment. Working familiarity with TypeScript and React. Hands-on experience using AI coding tools such as Claude Code, Cursor, or Codex, with the judgment to critically review generated code. Ability to work independently, solve ambiguous problems, and communicate technical decisions clearly. Must be based in San Francisco or New York City.

Nice to Have: Kubernetes, Kafka, Redis, gRPC, PostgreSQL, or GitOps. Experience in identity verification, cybersecurity, fraud prevention, or biometrics. Early-stage startup experience. Open-source contributions or meaningful personal projects. Experience building autonomous or agentic developer tools.

Salary: $150,000 - $225,000 per year

A bit about us:

We’re an early-stage AI and biometrics startup on a mission to make the internet more human, secure, and trustworthy.
