About the role (from employer)

OKX will be prioritising applicants who have a current right to work in Singapore, and do not require OKX's sponsorship of a visa.

Who We Are

At OKX, we believe that the future will be reshaped by crypto, and ultimately contribute to every individual's freedom.
 
OKX is a leading crypto exchange, and the developer of OKX Wallet, giving millions access to crypto trading and decentralized crypto applications (dApps). OKX is also a trusted brand by hundreds of large institutions seeking access to crypto markets. We are safe and reliable, backed by our Proof of Reserves. 
 
Across our multiple offices globally, we are united by our core principles: We Before Me, Do the Right Thing, and Get Things Done. These shared values drive our culture, shape our processes, and foster a friendly, rewarding, and diverse environment for every OK-er.

OKX is part of OKG, a group that brings the value of Blockchain to users around the world, through our leading products OKX, OKX Wallet, OKLink and more.
 

About The Opportunity

We are building the foundational data infrastructure that powers one of the world's leading crypto exchanges. As a Big Data Platform Engineer, you will design, build, and evolve the core platform services that enable hundreds of data engineers and analysts to move fast and ship reliable pipelines. You will be at the forefront of our AI agent initiative — embedding LLM-driven capabilities directly into the platform layer so that scheduling, cost optimization, and incident response increasingly run autonomously.

What You’ll Be Doing 

  • Platform Core: Design and operate large-scale distributed data systems
  • Own the big data compute and storage infrastructure (MaxCompute/ODPS, Hologres, Spark)
  • Build and maintain multi-site task orchestration that dynamically selects engines and enforces policy
  • Drive reliability and performance improvements across batch and real-time pipelines

 

  • AI Integration: Build the AI-native platform layer
  • Develop and expose MCP (Model Context Protocol) tool interfaces so AI agents can interact with platform APIs
  • Build the scheduling and cost-optimization agents that auto-tune resource allocation and alert severity
  • Instrument platform telemetry to feed AI-driven SLA monitoring and anomaly detection
  • Design context retrieval pipelines (RAG / vector search) for SQL code and config knowledge bases

 

  • Tooling & DX: Evolve the developer experience
  • Own the internal data development platform — IDE integrations, code review automation, deployment tooling
  • Build APIs-first tools (backfill, ingestion automation) designed for future MCP integration
  • Collaborate with data warehouse and service teams to define platform contracts

 

  • Ops & Governance: Drive operational excellence
  • Establish SLA benchmarks, cost metrics, and latency dashboards as AI optimization targets
  • Build automated incident response and root-cause analysis pipelines
  • Define and enforce infrastructure policies across multi-cloud environments
AI Agent Ownership — Platform Tier
  • Scheduling Agent: auto-configure task dependencies, engine selection, cost/performance trade-offs, and alert tiers
  • Operations Agent: detect pipeline latency, performance degradation, and schema drift; trigger remediation
  • Incident Response Agent: trace SLA breaches to root cause, assign accountability, generate post-mortems
  • MCP Tool Layer: design and maintain the cross-platform tool interfaces that all agents call into

What We Look For In You 

  • 5+ years of experience building large-scale data platforms (Hadoop/Spark/Flink or equivalent)
  • Deep expertise in distributed storage and compute systems (MaxCompute, Hologres, ClickHouse, Hive)
  • Strong software engineering skills in Java, Scala, or Python; experience with API-first design
  • Hands-on experience with task scheduling systems (Airflow, DolphinScheduler, or in-house equivalents)
  • Solid understanding of multi-cloud architectures and cost governance
  • Familiarity with LLM integration patterns: tool calling, RAG pipelines, context management
  • Experience with MCP or similar agent-tool frameworks is a strong plus
  • Passion for building systems that make other engineers 10x more productive

Perks & Benefits 

  • Competitive total compensation package
  • L&D programs and education subsidy for employees' growth and development
  • Various team building programs and company events
  • Wellness and meal allowances
  • Comprehensive healthcare schemes for employees and dependants
  • More that we love to tell you along the process!

Caterpillar (CAT) Formally Objects To Tokenized Trading Of Its Shares

Caterpillar (NYSE:CAT) has formally issued an objection to the listing of its equity on the OKX-ICE tokenized stock venue, citing a lack of authorization for the digital representation of its shares. The company expressed significant concerns regarding regulatory compliance and reputational risks associated with how its stock is accessed and marketed on the unregistered platform. This move highlights the friction between traditional corporate issuers and decentralized finance platforms that utilize SEC exemptions to offer tokenized versions of real-world assets. Because the OKX-ICE venue relies on a specific regulatory exemption that mandates the cessation of trading upon a written objection from the issuer, Caterpillar's action forces a direct test of these tokenization protocols. The company is prioritizing strict control over its brand and equity narrative, particularly as it manages a $72 billion backlog and complex global infrastructure operations. This development serves as a critical case study for the RWA market, illustrating how major industrial firms may push back against unauthorized digital asset representations. The outcome of this 30-day objection window will likely influence how other platforms approach the listing of tokenized equities without explicit issuer consent.

OKX to list Unified Tokenized Stocks xSHLD, xSQQQ and more for spot trading

OKX has launched Unified Tokenized Stocks, a new product line allowing users to trade price exposure to major stocks and ETFs on its spot market. These assets, identified by an 'X' prefix such as XAAPL or XTSLA, are powered by the xStocks framework developed by Payward. The platform supports 24/7 trading, enabling users to react to market news outside of traditional exchange hours by utilizing last-close pricing combined with market estimates. These tokens are compatible with the Solana and X Layer blockchains, allowing for deposits and withdrawals directly from the OKX ecosystem. By integrating these assets into existing crypto spot accounts, OKX eliminates the need for separate brokerage accounts or fiat currency conversions. Dividends are handled automatically through issuer-level reinvestment, which is then reflected as an increase in the user's share balance. This development marks a significant expansion in the accessibility of traditional equity exposure within the digital asset space, though the tokens do not confer actual shareholder rights or ownership of the underlying companies.

OKX Adds ETFs, Tokenized Stocks, And Stablecoins To Automated Portfolio Bot

OKX has announced an expansion of its Smart Portfolio Bot to include ETFs, tokenized stocks, and stablecoins, marking a shift from its previous cryptocurrency-only automated allocation model. This upgrade aims to provide users with diversified, lower-volatility investment options by blending traditional financial instruments with digital assets within a single interface. Despite the announcement, OKX has not disclosed a specific release date, the list of supported assets, or the fee structure for these new categories. The move represents a strategic attempt to differentiate the exchange from competitors like Binance and Bybit, which primarily focus on crypto-native automated strategies. Because tokenized stocks and ETFs often face strict regional regulatory constraints, the practical availability of these features remains unclear for many global users. The lack of technical specifications regarding custody, settlement, and rebalancing logic for non-crypto assets leaves significant operational questions unanswered. Ultimately, this development signals a broader industry trend toward integrating real-world assets into retail-facing automated trading tools, though the immediate impact is limited by the current lack of transparency.
