We operate a hybrid working model, requiring team members to attend the office 3 days a week.

• Commitment to a hybrid working model, attending the office 3 days a week
• Solid troubleshooting and problem-solving ability
• Experience with monitoring tools and system performance
• Familiarity with regular expressions
• Fluent written and spoken English is essential
• Candidates must already be based in Spain with the right to work

Nice to Have

• Networking knowledge (TCP/IP, UDP, Multicast) and the ability to explain fundamental protocol differences
• Experience with low-latency systems
• Exposure to financial markets or trading environments, specifically with FIX or ITCH protocols
• Experience with monitoring tools like Nagios, Opsview, or Zabbix
• Spanish language skills (useful for local team interaction)

• A short notice period

What Is On Offer

• Performance-related bonus
• Hybrid working (3 days in the office)
• Collaborative, international team environment
• Opportunity to work on cutting-edge trading systems
