We are an innovative AI tech lab building next-generation infrastructure for fully autonomous AI systems. We are currently scaling two core bleeding-edge products:
 

1. An Autonomous Agent Framework: A highly autonomous, "configure-once, forget-forever" agent platform that runs complex workflows, manages its own skills, self-corrects outputs, and operates without traditional approval loops or babysitting.
2. An Intelligence Engine: A massive-scale simulation platform capable of spawning hundreds of grounded AI agents within minutes to simulate real-world behavior, interact across social platforms (Twitter, Reddit), trade on prediction markets, and generate comprehensive counterfactual analysis reports.
    

We are looking for a Senior Backend Developer who is passionate about LLMs, multi-agent orchestrations, graph databases, and building autonomous workflows that operate seamlessly 24/7.
 

Core Responsibilities

• Architect Agent Lifecycles: Design, extend, and optimize the backend core responsible for autonomous agent task execution, state management, and memory retention.
• Scale Swarm Simulations: Improve the performance of multi-agent simulation environments, ensuring concurrent execution of hundreds of agents making API calls, processing text, and updating states in real time.
• Expand the Skills Library: Develop and integrate new "skills" and MCP (Model Context Protocol) tools for agents (e.g., automated code/PR reviews, web searching, live market monitoring, API integrations).
• Self-Healing & Quality Loops: Enhance automated fallback mechanisms, error handling, and self-patching algorithms where AI models evaluate their own outputs and fix failing tasks without human intervention.
• Data & Graph Modeling: Optimize data storage, retrieval, and relational modeling for agent memories, social graphs, and prediction market consensus.

Technical Requirements & Stack

• Languages: Deep proficiency in Python and Node.js/TypeScript (strong backend fundamentals are non-negotiable).
• AI & LLM Integration: Practical experience working with LLM APIs (OpenAI, Anthropic Claude, Ollama) and vector embeddings. Understanding of prompt chaining and structured outputs.
• Databases: Solid experience with Graph Databases (e.g., Neo4j) as well as relational or NoSQL solutions.
• Automation & CI/CD: Strong knowledge of GitHub Actions (used as a runtime framework), workflow dispatches, and containerization (Docker).
• Integrations: Experience building and consuming webhooks, REST APIs, and integrating with third-party platforms (Discord, Slack, Twitter/X, Reddit, or financial data feeds).
• Architecture: Familiarity with event-driven architectures, parallel/sequential task processing, and file-based state logging (Markdown/JSON).

Nice to Have

• Experience or strong interest in Web3, DeFi, and Prediction Markets (Polymarket, Base network ecosystem, tokenomics).
• Open-source contributions or a history of building custom AI tools/bots.
• Familiarity with local LLM deployment and inference optimization.

What We Offer

• 100% Remote & Flexible: Work from anywhere with asynchronous-friendly communication.
• Cutting-Edge Tech: No legacy enterprise maintenance. You will be shipping code to production for autonomous systems from day one.
• High Autonomy: Just like our agents, we value builders who don’t need micro-management and can own features end-to-end.
• Medical Insurance in Ukraine and Multisport program in Poland.
• Offices in Ukraine (Kyiv, Kharkiv) and Poland (Wroclaw) or Remote.
• Paid vacation, sick leaves, and official holidays.
• Legal & Accounting services.
• The company provides all necessary equipment.
• English classes and Education reimbursement.

We build AI-powered consumer apps. Our first product, Goodie AI, is a food analysis app live on both app stores, has reached 100K downloads in 6 months with 4.9 rating, and 100M+ views on TikTok, and is now heading towards an acquisition. 

Now we're scaling that playbook into a portfolio of new apps across different verticals. Same approach across multiple bets: AI-native and mobile-first.
 

  The Role
 

  You'll be our first engineering hire and a co-builder across everything we launch. This isn't a single-product job. You'll help us ideate,

  prototype, and ship multiple new apps, picking the right stack for each, building the first version, and getting it into users' hands. Some

  will be quick experiments. Some will become real businesses. You'll be in the room for all of it.

  What You'll Do

  - Go from idea to shipped product 

  - Make foundational architecture and technology decisions for new apps

  Strong plus:

  - Experience with mobile monetization (subscriptions, paywalls, RevenueCat, Stripe)

  - Familiarity with mobile growth & analytics (attribution, A/B testing, product analytics)

  - App Store and Google Play submission and release management

  - Background building multi-language / international products

  Nice-to-have:

  - Experience in health, nutrition, fitness, or consumer AI

  - Eye for design and UX. You can build something that looks good without a designer in the room

  - Prior founding or early-stage startup experience

  What We Offer

  - Founding-level equity

  - Real influence over what gets built and how

  - A team that's already proven it can ship 

  - The chance to build multiple products, not maintain one

We are a Performa HR agency, and we’re excited to find a strong professional for one of our clients. 

Here’s a short introduction to Performa HR agency:

Performa HR agency specializes in connecting top talent with leading companies across iGaming, IT, and Marketing. Our mission is to provide recruitment solutions that drive success for both employers and candidates. With deep market expertise, we help businesses scale by finding the right people for the right roles.

Location: Dubai (UAE), with a possibility of remote work during the probation period.
 

The Role
 

You will monitor deposits and withdrawals, investigate failed or delayed transactions, work directly with PSPs, banks, and internal teams, and help keep payment flows stable, secure, and scalable across fiat and crypto rails.

In parallel, you will contribute to the way the payments function is built: operating processes, internal documentation, fraud controls, escalation logic, and the interaction model between Operations, Risk, Finance and Customer Support.

We are looking for the candidate who is able to push issues through to resolution.

Responsibilities
 

Payments and Operations
 

• Monitor deposit, withdrawal, refund, and reversal flows across fiat and crypto payment methods.
• Ensure accurate and timely withdrawal processing within internal SLAs, including manual reviews, exceptions, and escalations.
• Track payment KPIs (approval rates, declines, payout speed, cashier conversion, failed withdrawals, refunds) and investigate transaction issues through to resolution.
• Participate with the reconciliation team in reconciling transaction data across PSPs, banks, wallets, custodians, and internal systems.
• Support Finance with settlement validation, fee checks, balance tracking, and daily payment controls. 
  
   

Payment Orchestration
 

• Manage operational communication with PSPs, banks, gateways, acquirers, and crypto processing partners.
• Configure and optimize payment orchestration logic in Praxis Tech, PaymentIQ, or similar platforms (routing, cascading, failover, limits, provider rules).
• Support launches of new payment methods, providers, currencies, and GEO-specific cashier setups.
• Coordinate investigations of settlement failures, missing callbacks/webhooks, stuck payouts, and other technical payment issues together with the IT team.
• Monitor provider performance and recommend improvements to approval rates, reliability, and cost efficiency.
  
   

Risk, Fraud, and Crypto Controls
 

• Monitor payment activity and player behaviour for fraud patterns, including multi-accounting, bonus abuse, account takeover, payment-method abuse, and withdrawal fraud.
• Participate in developing fraud-detection methodologies, risk policies, velocity checks, approval tiers, and escalation logic.
• Monitor crypto transactions using tx hashes, block explorers, wallet-screening and transaction monitoring tools; investigate crypto-processing issues.
• Support dispute and chargeback handling for non-crypto payment methods where applicable.
  
   

Customer Communication and Support
 

• Communicate with players via email and Customer Support channels regarding payment related issues.
• Define and maintain workflows between Payments, Customer Support, PSPs, and other internal teams.
• Train Customer Support teams on payment-related cases and escalation procedures.
  
   

Process Design and Reporting
 

• Participate in building payment operations processes and internal documentation.
• Define requirements for risk-management tools and services for the IT team.
• Prepare management reporting on payment performance, fraud trends, incidents, and operational KPIs.

Identify workflow gaps, propose process improvements, and participate in incident reviews and root-cause analysis.

Requirements

• Previous experience in payments operations/antifraud/risk in iGaming or similar operations.
• Experience with crypto processing, crypto cashier operations, or blockchain-based payment flows.
• Solid understanding of payment flows across cards, bank transfers, e-wallets, PSPs, and alternative payment methods.
• Strong Excel skills and confidence working with reconciliations, operational reporting, and transaction-level data.
• English level - C1.

Preferred Qualifications

• Strong mathematical background and analytical mindset.
• Practical understanding of crypto operations, including block explorers, wallet screening, sanctions exposure, network fees, congestion, and wrong-network/wrong-memo scenarios.
  
   

We Offer
 

• A key operational role with real ownership in an early-stage iGaming project based in Dubai.
• Relocation support where needed.
• Competitive compensation package discussed individually with each candidate.
