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

We’re looking for a pragmatic Node.js engineer who can help our non-technical team build and use AI-powered tools, agents, and reusable skills.

This is not a “deep architecture” or “big system design” role.

Your job is to:

• build useful AI-powered tools quickly
• create reusable “skills” and workflows
• simplify how non-technical people interact with AI
• teach others how to use and combine these tools

What you’ll do

• Build AI-powered internal tools (agents, workflows, assistants)
• Create reusable skills/modules that non-technical users can combine
• Integrate LLM APIs and connect them to internal data and tools
• Connect APIs (Slack, Google Sheets, CRM, etc.)
• Design simple workflows where AI helps automate decisions and tasks
• Help non-technical teammates:
  • understand AI tools
  • use them independently
  • combine skills into their own workflows

Example tasks

• Build an AI agent that generates reports from Google Sheets and sends summaries to Slack
• Create reusable “skills” like: lead enrichment, summarization, classification
• Build internal AI tools to assist non-tech teams in daily workflows
• Replace manual copy-paste work with AI-assisted automation

Who you are

• 2–5 years experience with Node.js / JavaScript / TypeScript
• Comfortable working with APIs and integrations
• Able to build simple tools quickly
• Can quickly dive into existing Jira tasks, codebases, and ongoing projects without long onboarding or heavy guidance
• Comfortable figuring things out independently from partially defined context

• Experience building AI agents or using LLM APIs

   

Bonus

• Experience designing reusable “skills” or modular workflows
• Basic frontend skills (React or similar)
• Familiarity with automation tools (n8n, Zapier, etc.)

Most important:

• you like making things simple
• you avoid overengineering
• you can explain technical concepts to non-technical people

Not a fit if you

• prefer building complex architecture over practical solutions
• only enjoy working with engineers
• need fully defined specs before starting

What success looks like

• Non-technical team automates parts of their own workflows
• Significant reduction in manual repetitive tasks
• Internal tools are actively used
• You become the go-to person for workflow improvements

Why this role matters

Instead of hiring more people, we want to multiply output using AI + reusable skills + internal agents.

You are the person who makes that practical and usable for the whole team.

We're building an AI-powered document processing platform that automates complex back-office workflows — from intake and validation to approval and ERP synchronisation. The system is already in production and handles real financial flows; you'll be joining at the scaling stage.

What you'll work on

• AI orchestration layer: LLM tool-calling pipelines (Claude / OpenAI), MCP server (4 domain tools), context and retry management
• Integrations: Microsoft 365 Graph API, DocuSign REST API, Azure Document Intelligence
• Validation & routing engine: business rules, confidence scoring, exception handling
• Backend API: REST + SSE, OAuth2/OIDC, audit logs, OpenTelemetry
• Frontend: React 18 + TypeScript + Tailwind dashboard (agent status, approval queue, analytics)
• Infrastructure: Docker, GitHub Actions CI/CD, Azure / AWS cloud

Required

• Node.js + TypeScript — 4+ years in production, architecture-level decisions
• LLM API integration — tool calling, prompt design, context management (OpenAI, Anthropic, or Gemini)
• REST API design + OAuth2/OIDC implementation
• PostgreSQL — schema design, query optimisation, migrations
• Microsoft 365 Graph API or similar enterprise API (SharePoint, OneDrive, Teams)
• Azure Document Intelligence / AWS Textract / similar document AI service
• React 18 + TypeScript — you can own the frontend when needed
• Docker + CI/CD (GitHub Actions or equivalent)
• Cloud deployment (Azure or AWS)
   

Nice to have

• DocuSign API experience
• MCP (Model Context Protocol) — building or consuming MCP servers
• pgvector / vector similarity for deduplication
• OpenTelemetry — metrics, traces, structured logs
• Tailwind CSS + shadcn/ui
   

We're looking for

Someone who has shipped AI-integrated features in production — not just experimented with them. You take ownership end-to-end: design → implementation → deployment → monitoring. You can make pragmatic architecture calls and explain trade-offs clearly.
 

Senior bar: you've led technical design of at least one non-trivial integration (enterprise API, document pipeline, or payment flow), and you don't need to be told what to research.
 

Offer

• Fully remote, async-friendly, EU time zone overlap (11:00–19:00 Kyiv)
• Small product team no bureaucracy, direct access to founders
• 24 days paid leave + public holidays
• 3-month probation period
