About Us
We’re a small, flat-structured team (5 people), working 100% remotely with flexible hours. We work on exciting customized solutions for Fortune 500 clients in collaboration with top US consulting firms, powered by our internal framework that we continuously improve and adapt for each project.

The Role
This role is primarily focused on Go. You’ll work across multiple Go codebases, extend our proprietary internal framework, and build tools and services in Go. You’ll also work with our backend stack and, when needed, dive into the frontend to contribute small features. We value engineers who use AI thoughtfully — as a tool to accelerate development, improve efficiency, and support innovation.

Requirements

• Strong hands-on experience with Go — this is essential.
• Ability to understand and contribute to existing codebases.
• Become familiar with our practical and approachable backend architecture: Docker, PostgreSQL, SQL.
• Comfortable working across the stack; frontend knowledge (React, NextJS, Typescript, MUI) is a plus.
• Able to leverage AI effectively to improve efficiency while maintaining engineering quality.

Who You Are

• Self-sufficient and comfortable owning projects end-to-end.
• Clear communicator in English (written & spoken).
• Adaptable to a fast, async team environment.
• Curious, willing to learn and share knowledge.

What We Offer

• 100% remote, async setup with global team and some coordination in U.S. Central Time (Chicago time zone).
• Fast-paced environment with a small, highly skilled team.
• Perfect for self-starters who thrive with independence.
• Stable, growing, and agile company with long-term opportunities
• Work directly on impactful projects for Fortune 500 clients.
• Creative freedom to solve problems your way.

How to Apply:

• Send a short paragraph explaining why you want to join us
• Include link to CV and (optionally) a personal blog, GitHub, or anything you’re proud of.
• *Direct applicants only. We are not working with agencies, recruiters, or outsourcing firms for this role.

We are seeking a Senior Golang Developer. It is essential that the person is highly product-driven, self-motivated, speaks excellent English, and enjoys using coding AI tools like Claude Code.

Our stack:

• Frontend: SvelteKit, turbo monorepo, Vercel
• Backend: Golang monorepo
• AI: Claude Code (mandatory), other agentic coding tools

What you'll actually do:

• Own features end-to-end: from specs to deployment to fixing bugs
• Use Claude Code to generate Golang backend code
• Review AI output for quality and architectural fit
• Fix bugs to learn our codebase, then rapidly build new features
• Make quick decisions on what to build vs buy vs generate with AI
• Talk to customers when they report issues and ship fixes the same day

You must have:

• Ownership mentality with a strive for elegantly simple, high-quality solutions
• Strive for max quality - you test your own work thoroughly since we have no QA team, everything you ship MUST work
• Product mindset - you care about WHY we're building something
• Proven experience using Claude Code or similar agentic AI (Cursor, Windsurf) 
• Strong Golang experience - you'll review AI's code in Golang, and you must understand how it works
• Broad architectural knowledge of building modern full-stack applications

• Excellent spoken English and a good internet connection for daily video calls

   

You are a great fit if you:

• Get frustrated when development takes weeks instead of days
• You think in features and architecture, and not single lines of code
• Can spot subtle bugs in AI-generated code quickly
• You ship fast, but always verify it actually works
• Have shipped real products that customers actually use
• Think "how can AI build this?" as your first instinct

‼️ Red flags (don't apply if):

• You've never used Claude Code or similar AI coding tools
• Your English is intermediate
• You need detailed specs before starting
• You see AI as a threat rather than leverage

🎯 Goal

Build a highly accurate and fast parser that processes poker table data in real time from a capture card feed, recognizes all required elements, and outputs the game hand line in our standard format.

⚠️ The parser’s task is pure parsing only (raw data extraction).
🚫 No analytics, EV calculations, or strategy logic.

📌 Requirements

1. Data Source
   • Input: capture card feed (video or screenshots).
   • Frequency: event-based (new action detected) or fixed interval (e.g., every 200ms).
2. What to parse
   • Hero’s hole cards (2 cards).
   • Board cards (street by street: Flop / Turn / River).
   • Player positions (UTG, MP, CO, BTN, SB, BB).
   • Player stacks in bb (convert from chips).
   • Pot size (POT) after each action.
   • Player actions (open, call, bet %, jam Xbb, etc.).
   • Game stage: PF / F / T / R.

3. Output format (single line)

    

   HAND: <POS> <HAND> | TABLE [ID]: <board or —> | POT <bb> | STACKS: <pos stack>... | LINE: PF <...> → F <...> → T <...> → R <...> → Hero act

4. When to output a line
   • After each active action (open / raise / bet / jam).
   • When the action reaches Hero.
   • 🚫 Skip folds.
5. PKO mode (bounties)

   • Add bounty info to stacks:

      

     BTN 24bb[$34]

6. Speed & Accuracy
   • Card recognition error ≤ 0%.
   • Stack recognition error ≤ 1bb.
   • Output update ≤ 0.5 sec after action.

📌 Example Outputs

Preflop

HAND: BB K♠️Q♦️ | TABLE [12]: — | POT 4.6bb | STACKS: UTG 28bb, MP 25bb, CO 31bb, BTN 18bb, BB(Hero) 22bb | LINE: PF UTG open 2.2bb → MP call → CO call → BTN call → Hero act

Postflop

HAND: BB 9♠️8♠️ | TABLE [12]: 9♣️ 7♦️ 2♠️ K♣️ 7♣️ | POT 12.3bb | STACKS: CO 27bb, BTN 24bb, BB(Hero) 19bb | LINE: PF UTG open 2.2bb → CO call → BTN call → BB call → F CO bet 33% (4.1bb) → BTN call → UTG fold → Hero call → T x/x/x/x → R BTN jam 18bb → Hero act

✅ Expected Result

• A ready-to-use tool (library / service) that:
  • Takes a frame →
  • Detects all objects (cards, stacks, pot, actions) →
  • Outputs a single line in the required format.
• Support for both cash games and tournaments (including PKO).
