## Job description

### About the Position

We’re looking for a Market Data Specialist to join our Metadata team, working on improving and supporting our internal golden copy Security Master and Corporate Action Management systems. You’ll be responsible for configuring our systems to improve data quality, helping with data cleaning and validation, solving support issues for internal clients, and interfacing with our data providers.

You’ll be embedded into the Metadata Systems Engineering team and will work with software developers, traders, and operations professionals across the firm.

### Responsibilities include:

- Investigating data quality and reliability issues

- Interfacing with exchanges or data vendors, raising, tracking, and resolving issues

- Helping us (the Metadata team and internal clients) understand our data better

- Potentially advising on solutions, e.g., changing monitoring

- Configuring internal services/tools and adding overrides

### About You

- Strong debugging and troubleshooting skills

- Excellent written and interpersonal communication skills

- Experience with financial instrument metadata, especially reference data preferred

- Programming experience in any language and knowledge of SQL or other database language(s)

- Confident in a Linux/Unix command-line-driven environment

- Responsible, organised, and great attention to detail

- Operations, support, and customer-centric experience a plus

- Fluency in English required

If you're a recruiting agency and want to partner with us, please reach out to agency-partnerships@janestreet.com.

**Live in Janestreet’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
