Description

Design, build, and release real-time decisioning systems that learn from interaction feedback at scale.
Own the modeling logic from user and signal representation through reward attribution and closed-loop improvement.
Move online learning policies, counterfactual estimators, and other prototype ideas into production code behind real-time APIs.
Design and build resilient streaming and batch pipelines for user state, reward signals, and offline replay.
Run A/B tests and offline evaluations to validate shipped systems and compare them against baselines.
Continuously monitor and improve system quality, latency, observability, and scalability.
Collaborate with platform and product teams to turn research ideas into production-grade products.
Share context, mentor engineers, and help raise the technical bar for machine learning at scale.

Requirements

Designed and deployed personalization, ranking, or recommendation systems used by real users and can speak to measurable engagement lift.
Experience with sequential recommendation, ranking, or joint/multi-objective optimization problems.
Experience A/B testing changes and iterating based on results.
Comfort working in production ML environments with cold start, sparse signals, label delay, feedback loops, and distribution shift.
Solid grounding in probabilistic modeling, including Bayesian inference, calibration, and hierarchical models.
Experience with modern recommender techniques such as embeddings, sequence models, and LLM-driven content understanding.
Strong software engineering skills and production-quality coding in at least one programming language, with attention to API contracts, testing, and observability.
Experience building high-throughput real-time or batch pipelines for ML training and inference on AWS or an equivalent major cloud.
Ability to own a service end to end across compute, storage, networking, and CI/CD.
Experience moving a model from a paper, notebook, or whiteboard sketch into a production system serving traffic.
Hands-on experience with online decision-making under uncertainty, multi-armed bandits, contextual bandits, Thompson sampling, UCB, or RL agents that have served traffic (strong plus).
Understanding of exploration vs. exploitation, regret, off-policy evaluation, and counterfactual estimation (strong plus).
Experience with causal inference or uplift modeling (strong plus).
Academic research experience or publications in online decision-making, reinforcement learning, sequential recommendation, optimization, or related fields (strong plus).

Benefits

Monthly meal allowance.
Comprehensive private health insurance.
Access to learning platforms including Spotify, LinkedIn Learning, Blinkist, MasterClass, Neoskola, and CloudGuru.
Internal trainings in AI fundamentals, coding, foreign languages, and personal development skills.
Fully remote work from anywhere in Turkey.
Eligibility-based ESOP to become a shareowner.
Referral bonuses.
Volunteering opportunities and purpose-driven social impact projects.
Global retreats, team-building activities, and year-round events.
Tech & Dev Talks and other industry events.
Continuous mentorship and technical coaching.
