Job description

Established in March 2018, Bybit is one of the fastest growing cryptocurrency derivatives exchanges, with more than 70 million registered users. We offer a professional platform where crypto traders can find an ultra-fast matching engine, excellent customer service and multilingual community support. We provide innovative online spot and derivatives trading services, mining and staking products, as well as API support, to retail and institutional clients around the world, and strive to be the most reliable exchange for the emerging digital asset class.Our core values define us. We listen, care, and improve to create a faster, fairer, and more humane trading environment for our users. Our innovative, highly advanced, user-friendly platform has been designed from the ground-up using best-in-class infrastructure to provide our users with the industry's safest, fastest, fairest, and most transparent trading experience. Built on customer-centric values, we endeavour to provide a professional, 24/7 multi-language customer support to help in a timely manner.

As of today, Bybit is one of the most trusted, reliable, and transparent cryptocurrency derivatives platforms in the space.

Key Responsibilities

• Assess the Status Quo — Develop an end-to-end understanding of the campaign lifecycle and available data assets; identify all decision points currently reliant on manual judgment (opportunity identification, audience selection, budget estimation, campaign mechanics design, post-campaign review) and determine where intelligent automation yields the highest return.
• What Campaign to Run — Mine campaign opportunities from user behavior, product and market signals, and historical campaign performance; build an AI Agent that outputs candidate campaign themes with clear supporting evidence, not just a ranked list.
• Who to Target — Build or reuse user segmentation and response/propensity models; apply uplift modeling to direct budget toward truly incremental audiences who would be influenced, rather than users who would convert anyway.
• How Much Budget — Build a cost-benefit model: projected participation, incremental trading volume / revenue, ROI simulation, budget allocation recommendations, and sensitivity and risk analysis (including abuse and reward-farming risks under incentive designs).
• Feasibility Analysis & Plan Design — Translate model outputs into a reviewable proposal: objectives, mechanics, target audience, budget, expected KPIs, and risk control boundaries; align with PM, Growth, and business stakeholders.
• MVP Delivery — Implement the end-to-end pipeline (data > model > recommendation > campaign configuration > A/B or holdout evaluation); run it on at least one real campaign or rigorous backtest; quantify improvement relative to the current manual decision-making baseline.

Requirements

• Undergraduate or graduate student in Computer Science, Data Science, Statistics, Economics, or a related field.
• Solid proficiency in SQL and Python. Experience with real-time / streaming tech stacks (Flink, Kafka) is a plus.
• Data science foundations relevant to this project: A/B experiment design, causal inference and uplift modeling, propensity/response models, and basic predictive modeling. Must be able to distinguish correlation from incremental effect.
• Hands‑on experience with LLM application development: prompt engineering, RAG, Agent / tool-calling frameworks; able to use LLMs for reasoning and orchestration on top of quantitative models.
• Business acumen: genuine interest in fintech / crypto and growth marketing; able to translate a business question ("Should we run a trading competition next month?") into a data problem, and translate the conclusion back into an actionable decision for business stakeholders.
• Strong communication skills — this role sits at the intersection of data, PM, and growth/marketing.
• Bonus: experience in growth / CRM / campaign analytics, recommendation systems, or marketing mix modeling background.
• Minimum 3-month internship commitment, 5 days per week on-site.
• Fluent in Mandarin is required.
