About the role
OneChronos is seeking a Site Reliability Engineer (SRE) to own the reliability, performance, and operational integrity of our trading platform across US, UK, and European market hours.
This role exists because our platform matters. It processes billions of dollars in securities transactions daily, and when something degrades or fails, it needs to be understood and corrected quickly—and prevented from recurring.
This is a senior, high-autonomy role for someone who treats production as a first-class system. You will operate at the intersection of software engineering and real-time systems, combining deep debugging ability with a bias toward automation, observability, and systemic reliability improvements. Over time, you will reduce operational burden on the engineering team by building the systems and practices that make the platform inherently more resilient.
About OneChronos (www.OneChronos.com) OneChronos is a technology company of diverse thinkers innovating at the intersection of capital markets, mechanism design, and operations research, working to grow the global GDP by designing and operating matching markets leveraging advances in auction theory and artificial intelligence. Our software and systems are developed in house and match billions of dollars per day of security transactions.
What You'll Do
- Own the reliability and performance of the trading platform across US, UK, and EU market hours
- Design, build, and maintain observability systems (metrics, logging, tracing, alerting) that provide clear, actionable insight into system behavior
- Triage, diagnose, and resolve production issues end-to-end across infrastructure, services, trade lifecycle, and market data systems
- Lead incident response, including mitigation, root cause analysis, and post-mortems with a focus on systemic fixes
