🚀 Listing Researcher (Web3 / Crypto) | Remote

We are growing our Web3 & Crypto ecosystem and are looking for a Listing Researcher to help us find and connect with crypto projects for listing on the PointPay platform.

This role is a strong entry point into Web3: you’ll adapt to Web3 listing workflows, understand how the process works end-to-end, and with solid performance you can grow into a Listing Manager role with high commissions and more independence — and later progress to a Listing Team Lead position (managing up to 8 listing agents).

🌍 About PointPay

PointPay is a crypto-in-one place platform that allows users to open current & savings accounts in cryptocurrency and earn daily interest accruals. We’re expanding our ecosystem by onboarding new crypto projects for listings.

💎 What we offer (benefits & guarantees)

• Company-provided training: video onboarding, standardized scripts, examples, and clear outreach requirements
• Transparent rules: you clearly understand what counts as a confirmed chat and how payouts are calculated, your average income per month can be 600-1700$ (pay per chats+ 1-3 deals)
• Predictable payouts:

— confirmed chats are paid once per month

— commission is paid within up to 1 week after deal closure

• Uncapped earning potential: no income ceiling — the more quality leads & deals you contribute, the higher your total earnings
• Remote + flexible location (work from anywhere)
• International team (EU, Ukraine, LatAm, Asia)
• Real growth track inside the listing team:

— Listing Researcher → Listing Manager (high commissions up to 25000 USDT)→ Listing Team Lead (up to 8 agents)

🕘 Team hours & overlap

Our team operates 09:00–17:00 (GMT+2, Kyiv, Ukraine time).

• 30–39 — $1.5 per chat
• 40–49 — $2 per chat
• 50+ — $2.5 per chat

Important:

• A chat is counted only if you independently initiate the contact and hand it over to the Listing Team Lead.
• Payout: once per month (based on monthly results).

2) Commission from successful deals

You receive 8% of the listing deal amount if:

• the project was found and brought in by you; and
• the deal was successfully closed by the Listing Team Lead.

Commission split (16% total):

• 8% — Listing Researcher
• 8% — Deal-closer (Listing Team Lead)

Minimum listing fee: $5,000 → your 8% = $400

Commission payout: within up to 1 week after deal closure.

🎯 Responsibilities

• search for crypto project contacts / decision-makers

About Tie

Tie is building the next generation of identity resolution and marketing intelligence. Our platform connects hundreds of millions of consumers across devices, browsers, and channels—without relying on cookies—to power higher deliverability, smarter targeting, and measurable revenue lift for modern marketing teams.

At Tie, AI is not a feature—it is a core execution advantage. We operate large-scale identity graphs, real-time scoring systems, and production ML pipelines that directly impact revenue, deliverability, and customer growth.

The Role

We are looking for a Senior AI / Machine Learning Engineer to design, build, and deploy production ML systems that sit at the heart of our identity graph and scoring platform. You will work at the intersection of machine learning, graph data, and real-time systems, owning models end to end—from feature engineering and training through deployment, monitoring, and iteration.

This role is highly hands-on and impact-driven. You will help define Tie’s ML architecture, ship models that operate at sub-second latency, and partner closely with platform engineering to ensure our AI systems scale reliably.

What You’ll Do

• Design and deploy production-grade ML models for identity resolution, propensity scoring, deliverability, and personalization
• Build and maintain feature pipelines across batch and real-time systems (BigQuery, streaming events, graph-derived features)
• Develop and optimize classification models (e.g., XGBoost, logistic regression) with strong handling of class imbalance and noisy labels
• Integrate ML models directly with graph databases to support real-time inference and identity scoring
• Own model lifecycle concerns: evaluation, monitoring, drift detection, retraining, and performance reporting
• Partner with engineering to expose models via low-latency APIs and scalable services
• Contribute to GPU-accelerated and large-scale data processing efforts as we push graph computation from hours to minutes
• Help shape ML best practices, tooling, and standards across the team

What You’ll Bring

Required Qualifications

• 5+ years of experience building and deploying machine learning systems in production
• Strong proficiency in Python for ML, data processing, and model serving
• Hands-on experience with feature engineering, model training, and evaluation for real-world datasets
• Ability to travel outside of Ukraine is a must
• Experience deploying ML models via APIs or services (e.g., FastAPI, containers, Kubernetes)
• Solid understanding of data modeling, SQL, and analytical workflows
• Experience working in a cloud environment (GCP, AWS, or equivalent)
• Experience with graph data, graph databases, or graph-based ML

• Familiarity with Neo4j, Cypher, or graph algorithms (community detection, entity resolution)

  Preferred / Bonus Experience

• Experience with XGBoost, tree-based models, or similar classical ML approaches
• Exposure to real-time or streaming systems (Kafka, Pub/Sub, event-driven architectures)
• Experience with MLOps tooling and practices (CI/CD for ML, monitoring, retraining pipelines)
• GPU or large-scale data processing experience (e.g., RAPIDS, CUDA, Spark, or similar)
• Domain experience in identity resolution, marketing technology, or email deliverability

Our Technology Stack

• ML & Data: Python, Pandas, Scikit-learn, XGBoost
• Graphs: Neo4j (Enterprise, GDS)
• Cloud: Google Cloud Platform (BigQuery, Vertex AI, Cloud Run, Pub/Sub)
• Infrastructure: Docker, Kubernetes, GitHub Actions
• APIs: FastAPI, REST-based inference services

What We Offer

• Competitive compensation, including salary, equity, and performance incentives
• Opportunity to work on core AI systems that directly impact revenue and product differentiation
• High ownership and autonomy in a senior, hands-on role
• Remote-first culture with a strong engineering and data focus
• Exposure to cutting-edge problems in identity resolution, graph ML, and real-time AI systems

• Clear growth path toward Staff / Principal IC roles

  What else:

• 4 weeks of paid vacation per year (flexible scheduling)
• Unlimited sick leave — we trust your judgment and care about your health
• US Bank Holidays off (American calendar)
• Remote-first culture and flexible working hours
• Flat structure, no micromanagement, and full ownership

• Opportunity to make a real impact during a critical growth phase

  Interview Process

• Recruitment Screening Call
• Initial call with Head of Data Science & AI and CTO  (30 min) in English
• Technical deep dive Interview (1,5h)  in English

• Optional test-task (paid)

  Why Join Us?

• High-impact delivery leadership role during a critical period
• Real ownership and autonomy
• Opportunity to shape delivery across the entire engineering organization
• Exposure to SaaS, data, integrations, automation, and platform work
• Collaboration with global teams and vendors
• A strong product with real scale and momentum

Why This Role Matters

At Tie, your work will not live in notebooks or experiments—it will power production systems used by real customers at scale. You will help define how AI is embedded into the company’s core platform and play a key role in making machine learning a durable competitive advantage.
