About Traffic Label

Traffic Label is an affiliate marketing group in iGaming, 18+ years in the market, 300+ clients. The group owns a crypto casino (5Bet), a CRM platform (Sway Gaming), and a marketing data subsidiary (Acrum). We build internal data products that drive player acquisition and retention across all brands.

Role Overview

We are building a Customer Data Platform (CDP) that ingests data from 10+ casino partners, builds a unified player profile, and activates marketing campaigns through multiple ESPs (DotDigital, Adestra, FastTrack).

The platform is live: 5 sources in production, 30-40 dbt models in the silver layer, working email campaigns through DotDigital.

You’ll join a Data Platform team of 5-10 engineers (Senior DE, QA, DA, PM) reporting to the Data Engineering Lead. You will own the ingestion layer, source integrations, and platform tooling. Your job: make it so that connecting a new data source takes days, not months. You’ll design and build reusable pipeline templates and own integrations with external systems (both inbound and outbound).

This is not a “write one pipeline and move on” role. This is “build the system that generates pipelines” + own the integrations that feed and consume data.

Why this role

Connecting a new data source currently takes 2-3 months. Your job: make it 5 days. This is a data platform engineering challenge, not a pipeline writing task.

This is the group’s flagship project. The CDP improves how the company works with players across all brands and directly generates revenue through better marketing activation.

The platform is 4 months old, modern stack, zero legacy. But already in production with real traffic, real campaigns, real money. You’re scaling a working system, not prototyping in isolation.

The core challenge is designing a system where adding a new data partner is a configuration. You’ll solve problems across the full spectrum: API design, schema evolution, orchestration patterns, data quality, and delivery to downstream consumers.

Key Responsibilities

• Design and build ingestion pipelines for REST API, database sources, etc., using Python
• Own ETL and Reverse ETL end-to-end, including implementation, deployment, operations, and incident handling.
• Understand how external systems work (casino platforms, ESPs, affiliate tools) to build reliable integrations with them.
• Design DAG patterns: dependency management, partial retry, backfill procedures.
• Implement and maintain authentication flows, token refresh handling, and secrets management.
• Monitor, troubleshoot, and resolve integration issues in production environments.
• Write and maintain automated tests to ensure the reliability and stability of integration services.
• Collaborate closely with Engineering, Product, and Data teams to support platform scalability and operational efficiency.
• Contribute to infrastructure improvements and Infrastructure-as-Code initiatives.
• Write Architecture Decision Records (ADRs) for significant design choices.

Skills & Experience

Must have:

• 6+ years in data engineering.
• Advanced Python: API clients, file processing, schema validation, integration logic.
• Deep Airflow experience: DAG design, dynamic generation, sensors, retry patterns, backfill, pools, connections management.
• dbt (mid+): bronze/silver models, source freshness, tests, materialisation strategy.
• Snowflake (mid): external stages, COPY INTO, storage integration, basic optimisation.
• API integration experience: authentication (OAuth, API keys), pagination, rate limiting, retry with backoff, error classification.
• Proven experience building reusable pipeline frameworks/templates that others use daily.
• Reverse ETL or outbound integration experience: pushed data from the warehouse to external systems.
• Writes clear documentation: architecture decisions, pipeline templates, and onboarding guides for the team.
• CI/CD pipeline design (GitHub Actions).

Nice to have:

• Terraform basics.
• Metadata-driven / config-driven pipeline experience.
• Experience with ESP platforms (DotDigital, SendGrid, Braze, or similar).
• Gambling, marketing, or multi-tenant data platform experience.
• Comfortable using AI coding assistants.

What We Offer

• Competitive salary.
• Fully remote work across Europe.
• Flexible collaboration hours and strong work-life balance.
• The opportunity to work on scalable, business-critical systems and integrations.
• A collaborative culture focused on ownership, innovation, and continuous improvement.

HOW YOU WILL MAKE AN IMPACT:
- Launch the project from scratch, including defining and executing the SEO strategy
- Collect, expand, and cluster semantic core across games, mechanics, and related user intents
- Design and develop site structure: categories, sections, and landing pages

- Develop and optimize internal linking structure

- Conduct basic SEO audits and create tasks for developers
- Monitor and control implementation of SEO improvements
- Optimize conversion from traffic to casino brand leads
- Perform competitor analysis and identify best practices
- Build and manage backlink profile using various strategies (white/grey/black hat)
- Implement optimizations to improve visibility in LLM-based search results

WHY YOU’LL LOVE IT HERE:
- Flexible working hours and a remote work setup, so you can plan work around your life and not your life around work!
- Unlimited vacation days and paid sick leave—because your rest matters.
- A competitive compensation that truly reflects your skills and expertise.
- Employee referral bonus and gifts to celebrate your special occasions.
- 50% financial support for learning expenses to supercharge your professional growth!

We're at the top of our field because we focus on delivering actionable AI for our clients. Our deep experience and product-first attitude set us apart from other groups and gets us the business results our clients want.

Why You Should Work With Us

You'll be exposed to a wide range of clients who are at the cutting edge of innovation in their field and get to work on fascinating problems, supporting real products, with real data.

Applied ML & Engineering

• Production ML experience: building, deploying, and maintaining models that serve real users at scale
• Strong Python skills including scikit-learn, pandas, NumPy, and at least one deep learning framework (PyTorch or TensorFlow)
• Solid statistical foundation: hypothesis testing, distributions, probability, experimental design

Communication & Working Style

• Experience translating model behavior, recommendations, and limitations for non-technical stakeholders, particularly in domains where trust and accuracy are critical
• Comfort working independently across multiple projects simultaneously
• English proficiency at B2 or above (written and spoken)

Nice to Have

• Experience applying LLMs or transformer-based NLP for structured text classification, information extraction, or embedding-based retrieval
• Geospatial feature engineering, location-based statistics, spatial indexing, or proximity scoring, particularly in land, infrastructure, or utility corridor contexts
• Experience with Vision-Language Models (VLMs) or satellite/aerial imagery analysis for document or land parcel interpretation
• Experience with cloud ML platforms (AWS SageMaker, GCP Vertex AI)
• Exposure to utilities, energy, infrastructure, land management, or enterprise SaaS domains
• Experience fine-tuning or adapting pre-trained models (LoRA, PEFT, or full fine-tune)
• Experience with agentic architectures and deployments

Responsibilities

• Design, develop, and maintain modern web applications using Node.js and Angular.
• Build robust RESTful APIs and backend services.
• Develop responsive, high-performance frontend interfaces.
