• Generate several fundamentally different creative concepts every week — not variations of the same idea.
• Research competitor ads, identify strong mechanics, and turn them into even more effective versions.
• Create UGC-style videos that blend naturally into the feed and don't feel like ads.

• Launch hypotheses, read the data, adjust your approach, and repeat the cycle.
• Occasionally contribute to landing page and presentation design for the product.

Requirements

The role:
You'll be picking up tickets that span our entire stack: Rails API, Next.js frontend, and infrastructure config, and shipping complete solutions without someone else catching what you missed. This is not a "build a component and hand it off" role. You own the ticket from read to deploy.
 

Our team is three people: a technical lead, a frontend/payments developer, and a QA engineer. We move fast, we communicate asynchronously in Linear, and we expect clean PRs with clear descriptions. If you're someone who reads half the ticket and ships half the solution, this isn't the right fit.
 

What you'll work on:
- Feature development across Rails and Next.js (new quiz features, student-facing tools, admin functionality)
- Bug fixes that touch multiple layers: a single ticket might involve an Nginx config change, a Rails controller update, and a Next.js page fix
- Infrastructure work as we migrate hosting to Render
- Security hardening and deployment pipeline improvements 
- Writing tests and catching your own edge cases before QA does

What we're looking for: 
- 5+ years of professional experience with Ruby on Rails and 3+  years of professional experience React/Next.js 
- Deployed to managed PaaS platforms: Render, Vercel, Railway, or similar. We're not looking for someone whose only deployment experience is SSH-ing into a VPS. 
- AI-native workflow. You should be using Cursor, Claude, GitHub Copilot, or similar tools as a core part of how you write code, not as an occasional convenience. We'll ask you to demonstrate this. 
- Clean communication. You read the full ticket. You ask clarifying questions before you start, not after you've shipped something incomplete. Your PR descriptions explain what changed and why. 
- Self-directed. You don't wait to be told what to do next. You pick up the next ticket, you flag blockers early, and you ship.

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

• 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

• Build and maintain MCP Servers to expose internal REST/HTTP APIs to AI agents, enabling seamless tool-use across the development lifecycle.
• Champion UI/UX best practices while maintaining clean, maintainable code using ESLint, Prettier, SonarQube, etc.
• Act as a Feature Lead, leading the architecture, technical documentation, communication with CTO, Tech Lead and Product Owner on the best tech realization of the selected feature.

• Ability to author and interpret detailed technical specifications for front-end and back-end features, enabling efficient development through AI agents.
• Solid experience working in a Serverless environment (especially with Google Cloud Platform: Firebase, Cloud Run/Functions, App Engine, Logging, API Gateway).
• Deep understanding of REST APIs.
• Experience with CI/CD workflows using GitHub Workflows/Actions.
• A strong drive to build products through AI Agents rather than writing code manually.
• English: intermediate level or higher.
