Our team of engineers, quantitative researchers and data scientists looks beyond the traditional to test hypotheses and develop creative solutions to some of the world’s most complex economic problems.

We are seeking a talented Data Operations Analyst to join our Global Data Operations team in London. 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’ll 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. We are looking for someone who is comfortable at the level of the database, the shell, the job log, and the file system, who can pull apart a problem with a diverse set of tools, and who wants to make our operations measurably better by writing and improving the runbooks we run every day.

You will take on the following responsibilities:

Investigate and remediate production alerts using incident-specific runbooks, owning each issue through to resolution or escalation
Author and improve runbooks, applying existing data-management workflow standards, turning recurring, ad-hoc fixes into clear, unambiguous, repeatable procedures that lower operational risk and increase throughput
Mine our data to surface patterns and help root-cause issues, validate data, and reveal trends across large volumes
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

Comfort with underlying technology. You can work behind the UI: the UNIX/Linux command line, querying databases (SQL) to mine and validate data, reading logs, and navigating file systems, schedulers, and storage
Exposure to scripting – Bash, Python, or a similar language – and the judgment to know when a script helps and when a runbook is the right answer
A genuine pull toward operations: you like to execute daily, at volume, follow workflows to the letter, and feel the immediate impact of work done right
Comfort switching between systems and tools – Linux/Windows, database/file-server, UI/command-line, text/numbers – without being dependent 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 required; 1-5 years of experience preferred

Hands-on experience performing data-management and data-quality tasks in data-intensive environments
A desire to grow your knowledge of finance and trading
