Our team of engineers, quantitative researchers, and data scientists tests hypotheses and develops creative solutions to some of the world’s most complex economic problems. ## Location London, United Kingdom ## Team & Focus Global Data Operations (GDO) is a service provider for data-driven operations and operational risk management. We create, maintain, and operate the optimized workflows that provide and curate the data used in live trading. You will be part of a close-knit, global team whose daily execution is essential to the success of Two Sigma’s business. This is a hands-on, technical operating role requiring comfort with the underlying technology, including the UNIX/Linux command line, databases, logs, and file systems. You will work to make our operations measurably better by writing and improving the runbooks we run every day. ## Responsibilities - Investigate and remediate production alerts using incident-specific runbooks, owning each issue through to resolution or escalation. - Author and improve runbooks, applying data-management workflow standards to turn recurring fixes into clear, repeatable procedures that reduce risk and increase throughput. - Mine data to surface patterns, root-cause issues, validate data, and reveal trends across large datasets. - Apply predefined acceptance and quality criteria to guarantee the integrity of financial data sets. - Collaborate with business partners, software engineers, data analysts, and other data operations specialists to understand and improve business processes. - Recommend and improve data-management policies and procedures to enhance efficiency and accuracy. ## Qualifications - Comfort with underlying technology: use the UNIX/Linux command line, query databases (SQL) to mine and validate data, read logs, navigate file systems, schedulers, and storage. - Exposure to scripting (Bash, Python, or similar) and the judgment to know when a script helps versus when a runbook is the right answer. - A genuine interest in operations: you execute daily at volume, follow workflows precisely, and feel the impact of work done right. - Ability to switch between systems and tools (Linux/Windows, database/file-server, UI/command-line, text/numbers) without relying on a single framework. - Strong attention to detail and exceptional verbal and written communication. - BS in a technical discipline or equivalent hands-on experience in a comparable operational or technical role. - Minimum 1 year of experience; 1–5 years is preferred. ## Preferred Experience - Professional experience in data operations, technical operations, or a similar discipline (e.g., data operations analyst, systems/support engineer, data analyst, process engineer, systems administration, QA) or a structured operational background (such as defense analysis, logistics, or maintenance technician work) where you followed and built step-by-step procedures and worked with data and tooling. - Hands-on experience performing data-management and data-quality tasks in data-intensive environments. - Desire to grow knowledge of finance and trading. ## Hours & Work Schedule This is a London-hours operational role within a global team supporting trading 24/5 across Houston, Tokyo, and London. The work is interrupt-driven and time-sensitive, with early starts (approximately 7:00 AM London time) to cover the period before and during the trading day.
