Full Stack Web Developer - Application

Contract Software Engineer (AI Applications / High-Velocity Builder)

Location: Remote
Compensation: Contracted hourly
Type: Project-based (20–60 hrs/week)

About Us
We are a stealth AI company building infrastructure that powers reinforcement learning (RL) environments for leading AI labs. Our systems sit directly in the training loop of modern AI — shaping how models are evaluated, improved, and deployed.

This is applied, production-facing work — not experimentation for its own sake.

Role Overview
We’re looking for strong engineers who can own and ship complete applications quickly in fast-moving, low-structure environments.

You should be a high-quality builder first, who also knows how to leverage modern coding tools (including AI assistants / Claude Code / Codex) to increase speed and throughput — without compromising on correctness, maintainability, or system design.

We expect you to use coding agents but not rely on “vibe coding”. You are expected to:

• Understand the systems you build

• Make sound architectural decisions

• Use AI as an accelerator, not a crutch

What You’ll Do

• Build full-stack applications end-to-end (frontend, backend, infra)
• Translate loosely defined ideas into production-ready systems
• Design and implement systems for RL environments and agent workflows
• Ship quickly while maintaining code quality and clarity
• Iterate directly with founders and researchers

How You’ll Work

• One project per engineer - Report to an engineering manager
• You move very fast, but not blindly - All through Slack
• You use tools like Cursor or Claude Code to accelerate development, not replace thinking
• You review, refine, and take ownership of all generated code
• You are comfortable going from 0 → deployed system independently
• You do not need or expect regular guidance from a more senior engineer

This is not a role for someone who wants to ask questions and meet often. This person should be comfortable receiving a project spec document and being able to quickly produce results without the need for oversight.

What We’re Looking For

• Proven ability to build and ship complete applications end-to-end
• Strong generalist engineering skills across:
  • Frontend (React)
  • Backend (Python, FastAPI, Next.js etc.)
  • APIs and integrations
• Solid understanding of:
  • System design and tradeoffs
  • Debugging and performance
  • Writing maintainable, production-quality code
• Experience with:
  • LLMs, agents, or AI-powered systems (preferred)
  • Data pipelines or scraping systems (plus)
• Demonstrated ability to use modern tooling to increase output without lowering standards
• High ownership mindset — operates well with minimal direction

Ideal Candidate Profile

• Has built and deployed multiple real-world products
• Comfortable owning systems end-to-end
• Prior startup, freelance, or rapid-build environment experience
• Uses AI tools pragmatically to move faster — but can build without them
• Thinks in systems, not just tasks

What This Is Not

• Not a narrowly scoped frontend or backend position
• Not a heavily managed or process-driven environment
• Not a project we need to design around the market / user feedback

Why This Role

• Work on infrastructure used by leading AI labs
• High autonomy and real ownership
• Fast iteration cycles and meaningful output
• Remote flexibility
• Opportunity to become a core contributor over time
   
• No long meetings or adaptive to user feedback

Example Work

One example project could be a two-week project where you are asked to rebuild an exact replica of AirBNB

Timeline: 14 days

The app needs to include full functionality of the whole web app, including:

• An interactive map view
• A scrollable search results panel
• Property detail pages
• Realistic mock data seeded into a local database
• Filtering, sorting, grouping, and shareable URL state
• Offline functionality with no external runtime APIs, hosted assets, or external map tile servers

• A production-style frontend/backend architecture

   

Example Tech Stack

• Frontend: TypeScript, React, modern UI library (e.g., Chakra UI), state management (e.g., Jotai)
• Backend: Python (FastAPI), SQLAlchemy
• Database: SQLite (or similar)
• Mapping: MapLibre GL JS (or equivalent)
• Monorepo / Build: Nx (or similar), pnpm
• Linting / Tooling: ESLint, Ruff
• Optional: OpenAPI-generated clients for type-safe frontend/backend integration

The expectation would be that you can study the reference product, identify the core user flows, scope the right features, and build a complete working application end-to-end - All without any oversight or help.

This could include:

• Designing the database schema
• Seeding 1,000+ realistic records with internally consistent mock data
• Building a React/TypeScript frontend
• Building a Python/FastAPI backend
• Implementing map interactions, filters, search state, detail pages, loading states, and empty states
• Matching the visual and functional behavior of the reference application closely
• Ensuring the app can be cloned, bootstrapped, and run locally with minimal setup

The work will be evaluated on scoping, visual fidelity, functional completeness, data quality, and architectural quality.

About the Company:

What We Offer:

• Fully remote position

Important requirements:

• 3+ years of experience in a similar role
• Fluent in Russian and English

Why This Role

You'll build systems that move real money and digital assets — exchanges, payment rails, crypto processing, and OTC desks — where every decision touches security, latency, and correctness. The

problems are real: real adversaries, real settlement guarantees, real users who can't afford downtime. If you want ownership over production fintech infrastructure rather than another CRUD app, this is that.

You'll join a small team shipping to production frequently, owning features end-to-end across our backend services, customer-facing products, and internal back-office tools.
 

Tech Stack

- Backend: Python 3.12, FastAPI, SQLAlchemy + Alembic, Gunicorn/Uvicorn

- Frontend: React 18 + TypeScript, Vite, Tailwind + shadcn/ui, React Query

- Back-office: React 18 + TypeScript, Vite, Tailwind + shadcn/ui

Databases: PostgreSQL 17 + MongoDB
 

What You'll Do

- Own full-stack features from spec through deployment, monitoring, and iteration

- Build and maintain FastAPI services handling payments, exchange, and crypto-processing flows

- Develop responsive interfaces for both customer-facing products and internal back-office tools

- Model and optimize data across PostgreSQL and MongoDB; manage migrations with Alembic

- Integrate third-party payment, banking, and crypto APIs

- Bake security and compliance into everything — you'll be trusted with money-handling code, often without a dedicated QA safety net
 

Must Have

- 5+ years full-stack experience, with at least 3 building production backend services

- Strong command of Python / FastAPI and React + TypeScript

- Solid experience with PostgreSQL (relational modeling, query optimization)

- Advanced, daily use of AI tools in your workflow — you use assistants like Claude, Copilot, or

- Cursor to scaffold, refactor, and review code, and you can judge when to trust their output and when

to discard it

- Genuine independence — you take ownership, make sound calls, and drive work forward with minimal oversight (essential on a remote, fast-moving team)
 

Bonus

- Experience with MongoDB and the wider frontend stack (Vite, shadcn/ui, React Query)

- Fintech background — payments, banking, PSP, or exchanges

- Crypto / digital assets — exchanges, processing, custody, or OTC (a strong extra plus)
