Full Stack Engineer – Tutoring Platform

**Full Stack Developer (Node.js & React.js)**

Long-Term Contract (12 Months or More, with Possible Extension)

100 % Remote

**Need candidates on W2**

We are seeking a **Node.js Developer** with **React.js** experience t with **8+ years of overall experience** in software development to design, develop, and maintain scalable web applications using Node.js and React.js.

The ideal candidate should have strong expertise in RESTful API development, front-end integration, database management, system architecture, and performance optimization, with a proven track record of writing clean, scalable, and maintainable code.

Full Stack Engineer

**THE JOB**

VerifyYou is building infrastructure that keeps the internet human. Co-founded by Reddit’s former CTO, Marty Weiner, we’re focused on solving identity online and enabling platforms to stop bots and fake accounts.

We’re hiring a full-stack engineer (backend-leaning, 2-5+ years) to help architect and scale the systems behind our verification layer, with a strong focus on ML-driven signal pipelines and production data systems.

**WHAT YOU’LL DO**

• Design and evolve signal pipelines that distinguish real human participation from automation, including liveness, uniqueness, and behavioral authenticity. Build modular detection systems tuned to specific threat classes such as replay attacks, synthetic identity farms, and coordinated abuse.

• Build and scale Python-based services that power our verification engine. Architect privacy-preserving data flows, event-driven ingestion pipelines, and storage systems that handle sensitive biometric and behavioral data responsibly.

• Develop internal evaluation frameworks to measure false positives and false negatives, test bypass resistance, and support continuous red-team iteration against evolving attack patterns.

• Deploy and operate services on GCP with strong observability, reliability, and security practices as we scale toward compliance and platform-grade resilience.

**OUR STACK**

Backend: Python (Flask, FastAPI)

Data & Storage: Firestore, event-driven pipelines (Pub/Sub)

Infrastructure: GCP, containerized services

Frontend: React + TypeScript

Mobile: React Native, some Swift/Kotlin

Signal & ML Systems: training data management, Milvus vector stores, model integration, evaluation, and performance monitoring

**REQUIREMENTS**

• 2–5+ years of professional software development experience.

• Proficiency in at least one backend language (we use Python) with a solid understanding of REST/gRPC APIs, database design, authentication, and authorization patterns.

• Experience with relational databases, including data modeling, migrations, and query optimization.

• Working knowledge of frontend frameworks (React, TypeScript, or similar) sufficient to contribute across the stack.

• Familiarity with cloud infrastructure, ideally GCP.

• Strong CS fundamentals: data structures, algorithms, system design, and networking basics.

• Hands-on exposure to data pipelines, ML model integration, or model evaluation in production systems, including training workflows, feature stores, monitoring, or experimentation frameworks.

**NICE TO HAVE**

• Experience with identity, authentication, or security-focused systems.

• Familiarity with biometric verification, face recognition, or liveness detection technologies.

• Experience supporting ML systems in production, including data pipelines, feature engineering workflows, model deployment hooks, or performance monitoring.

• Background in privacy-preserving architectures or cryptographic protocols.

• Experience with CI/CD pipelines, infrastructure-as-code, and observability tooling.

• Some web or mobile frontend development experience.

**WHY VERIFYYOU**

The internet has evolved into critical infrastructure, but its trust model hasn’t kept pace. AI has made synthetic participation trivial, and legacy solutions like CAPTCHAs and phone verification are either fragile or invasive. VerifyYou is building verification infrastructure that proves humanness while keeping personal data private.

You’ll own and ship major product components with real autonomy, collaborate directly with founders and senior technical leadership, and receive competitive base pay plus meaningful equity.

**INTERESTED?**

*   Work closely with Product & Design to translate complex Earn/crypto concepts into intuitive, user-friendly, and performant UI/UX across user types (krak, consumer & pro)
*   Mentorship and technical leadership: guide and review frontend engineers, influence roadmap choices, and act as a cross-pod technical leader

The Opportunity

*   Architect, build, and maintain scalable, maintainable, high-performance frontend applications across React / Next.js / React Native (or similar) stacks
*   Build reusable UI components, shared libraries/styles, and abstractions to support multiple apps and platforms
*   Optimize web/mobile performance, reliability, load-times — especially critical for financial and crypto features involving real-time data
*   Ensure UX consistency and quality (design system adherence, responsive/mobile-first, accessibility, edge-case handling)
*   Define and enforce frontend testing, monitoring, and quality standards
*   Collaborate across teams — backend, devops, services, design, product — to shape APIs, data flows, error-handling, and user flows, particularly for Earn features and DeFi integrations
*   Serve as a senior technical voice in architecture, tech-strategy, and long-term frontend planning

Skills you should HODL

*   6+ years (or equivalent) professional experience delivering complex web and/or mobile applications
*   Deep expertise with JavaScript/TypeScript, React (or equivalent component-based framework), and modern frontend ecosystems (e.g. Next.js, React Native, consistent build pipelines)
*   Strong foundation in HTML5, CSS3 (or CSS-in-JS / styling solutions), responsive layout, cross-browser/device compatibility, accessibility, UI/UX best practices
*   Experience architecting large-scale, maintainable frontend systems — component libraries, shared modules, code reuse, scalable state management, performance tuning
*   Proven ability to lead technical direction, influence design and architecture decisions, and deliver across multiple applications or codebases
*   Excellent collaboration skills — able to work closely with backend/service teams, design, product, and other stakeholders to deliver cross-functional features
*   Strong problem-solving, analytical thinking, and ability to trade off short-term needs with long-term architecture/maintainability
*   Experience building or maintaining shared UI component libraries or SDKs across multiple platforms (web & mobile)
*   Background with backend-integration patterns, API-driven frontend design, state management for real-time data, and cross-platform consistency
*   Demonstrated track record of mentoring, code reviews, engineering culture influence, and driving engineering excellence across teams

Nice to Haves

*   Previous experience working in fintech, crypto, trading, or yield/interest-bearing products — familiarity with financial flows, security implications, real-time data
*   Familiarity with crypto-specific UX challenges (e.g. wallet flows, permission/consent flows, error-handling for financial/deFi services)

Why This Role Matters

*   You’ll own the core frontend foundation for one of Kraken’s most strategic offerings — Earn, used by millions, across Krak, consumer & pro platforms
*   Your work shapes how users interact with high-impact financial and DeFi products — from usability and performance to security and reliability
*   As a Staff-level engineer, you’ll influence not just code, but architecture, cross-team standards, and long-term platform scalability
*   The role sits at the intersection of product ambition, frontend excellence, and crypto innovation — a rare opportunity to build at scale in a mission-driven domain
