About the project

We’re building a Web3 Mining-as-a-Service (MaaS) platform. Users access real Bitcoin mining infrastructure and track daily rewards, performance, and upgrades inside a dashboard (trustworthy, fintech-grade UX).

• Ability to iterate quickly: same-day / next-day corrections when needed
• Comfortable collaborating directly with devs

Nice to have

• Web3 / crypto product experience (wallet-like flows, rewards/staking UX, exchanges)
• Understanding of Tailwind / utility-first layout constraints
• Experience working with existing UI libraries (HeroUI, shadcn/ui, Material, etc.)
• Tasteful micro-interactions / motion (optional)

Process

• Short intro call
• Portfolio review (must include complex web apps / dashboards)
• Optional small  test task (scoped, realistic, fast)

Work format

• At least 4 hours of daily overlap with the team (roughly 10am–2pm CET, meetings usually around 11:00 CET)
• Team coordination in CET / Eastern European time
• Working language: English (Russian may be used inside the team)

Compensation & Benefits

• Rate: 20–30 EUR/hour (depending on portfolio and speed/ownership)
• Payment: Monthly via bank transfer or USDT
• Vacation: 20 days paid time off per year
• Contract type: B2B contractor

Benefits:

• Flexible work schedule
• Agile execution with fast feedback and minimal bureaucracy
• Small, focused team with end-to-end ownership
• Hands-on experience in a real crypto-finance product (not “theory Web3”)
• Ability to influence UX, interface patterns, and product decisions
• Exposure to multiple product areas (dashboard, onboarding, growth mechanics)

How to apply

Send:

1. Portfolio link (with 1–2 relevant dashboards/web apps)
2. Short note: what you personally owned end-to-end (flows/system/handoff)

A core part of this role is working AI-first: we expect you to use Claude Code as a primary development tool, not as an experiment or side-assist.

The Role

You’ll design and implement the full production backend for our React-based SaaS platform, replacing mock data with real infrastructure:

• databases
• authentication
• APIs
• AI integrations
• deployment pipelines

You’ll also contribute directly to the frontend where needed.

Claude Code is a hard requirement.

We expect you to be comfortable (or explicitly motivated) to:

• scaffold systems with AI
• refactor and evolve large codebases using AI assistance
• co-design architecture with Claude
• use AI for documentation, tests, migrations, and reasoning

This is an AI-augmented engineering role, not a traditional “write everything by hand” position.

What You’ll Build

Backend Architecture

• Fastify REST API

  High-performance Node.js framework with TypeScript-first design and built-in validation

• Database

  PostgreSQL 15 with Prisma ORM (type-safe queries + automated migrations)

• Authentication & Authorization

  JWT with refresh tokens, httpOnly cookies, and role-based access control

• Caching Layer

  Redis for sessions and performance optimization

• Validation & Types

  Shared Zod schemas between frontend and backend

• API Design

  RESTful endpoints with structured error handling and consistent responses

Infrastructure & DevOps

• Monorepo Setup

  pnpm workspaces separating frontend, backend, and shared packages

• CI/CD

  GitHub Actions with automated tests, security checks, and deployments

• Environments

  Isolated staging and production environments

• Deployment
  • Frontend: Vercel (CDN + edge)
  • Backend: Railway or Supabase (auto-scaling)

• Containerization

  Docker-based local and production environments

Integrations

• OpenAI API

  Document parsing, analysis, and intelligent matching logic

• Email Services

  Resend or SendGrid with template-driven transactional emails

• File Storage

  Secure uploads via Supabase Storage or AWS S3

• Monitoring & Analytics

  Sentry (errors) and PostHog (product analytics)

Testing & Quality

• Backend Testing

  Vitest for unit and integration tests with test databases

• End-to-End Testing

  Playwright covering full user workflows

• Code Quality

  ESLint, Prettier, Husky pre-commit hooks

• API Documentation

  Auto-generated OpenAPI specs from Zod schemas

Required Experience

• 5+ years of professional full-stack development
• Strong experience or strong willingness to work AI-first
