The Role in a Nutshell

This is not a pure research position.

You’ll work on improving production AI systems through structured evaluation, diagnosing failures, refining prompts and agent workflows, and designing measurable improvements.

You won’t be working in isolation — you’ll improve systems that users depend on daily.

Responsibility Breakdown (Approximate)

• AI evaluation & KPI design — ~30%

1️⃣ Strong AI/ML Fundamentals (Must-Have)

You understand the theory behind what you build and can choose appropriate methods.

Examples:

• Evaluation metrics (precision, recall, F1, etc.)

Not required:

• Academic publications
• Advanced theoretical math
• Large-scale model training experience

2️⃣ Evaluation-Driven Mindset (Most Important Signal)

Responsibilities

• Create and refine player communication content (primarily SMS): adapt templates for different segments and scenarios, keep tone and structure consistent, write short compelling offers.
• Support preparation of CRM/retention funnel launches: define variables, segments, conditions, logic, and write clear launch specs/documentation.
• Hand off well-structured tasks to the team that builds/launches CRM funnels (so implementation is fast and unambiguous).
• Monitor funnel/campaign performance and track key metrics:
  • call reachability / contact rate
  • delivery rate
  • CTR
  • conversion and other funnel efficiency indicators
• Help validate hypotheses and gather data in collaboration with analysts (samples, cohorts, segment cuts, before/after comparisons).
• Assist with A/B testing (texts, offers, segments, timing, channels): set up, track, document outcomes and recommendations (scale/stop/iterate).
• Propose and improve operational processes: templates, checklists, documentation standards, launch workflow transparency.

Requirements

• Junior-level hands-on experience or solid understanding of CRM funnels / retention mechanics.
• Ability to work with performance metrics and make conclusions (delivery/CTR/conversion/contact rate).
• Strong attention to detail in operations: variables, templates, documentation, status tracking.
• Good written English (clear, concise, persuasive messaging).

Nice to Have

• Experience in iGaming / gambling / betting (player promo, retention, CRM).
• Prior experience running or supporting A/B tests and hypothesis-driven optimization.
• Understanding of player segmentation (new/active/dormant/VIP) and lifecycle messaging.
• Ability to support client-facing reporting if needed (not a core responsibility).
