About The Position

oneZero Financial Systems is hiring a Director of Reliability Engineering to build its SRE team and lead reliability engineering across a global production environment. The role partners with engineering and operations leaders to identify consequential production risks and translate priorities into engineering work. The director will shape the team, select its tools and practices, and determine where to invest first. The position begins with one direct report, with plans to hire additional team members in 2027.

This is a hands-on leadership role involving major incident leadership, investigation of difficult production problems, and writing or reviewing automation, alongside hiring and developing the team. The role focuses on improving reliability, observability, recovery readiness, release safety, and on-call practices while communicating service health and production risk to technical, executive, and client-facing audiences.

Requirements

• At least eight years of experience engineering or operating critical production systems.
• At least three years leading engineers or setting the technical direction of an SRE, platform, or comparable team.
• Evidence of decisions that improved reliability, with the ability to explain the problem, trade-offs, and resulting changes.
• Experience leading major incidents in distributed cloud systems, with technical depth to investigate failures and composure to guide recovery.
• Ability to write and review production automation, assess system designs, and work directly with engineers on difficult technical problems.
• Experience hiring and developing engineers and getting work done across teams the role does not manage.
• Clear communication about technical failures, business risk, and engineering trade-offs with engineers, executives, and clients.

Nice To Haves

• Experience building an SRE practice, supporting production across time zones, or working in trading, market data, or financial services.
• Familiarity with AWS, containers, infrastructure as code, CI/CD, and observability platforms such as Datadog.
• A degree in Computer Science, Engineering, or a related field; equivalent practical experience is also accepted.

Responsibilities

• Build and lead the SRE team by hiring and developing engineers, setting priorities, and providing support and responsibility.
• Set the reliability agenda with engineering and operations leaders, using production evidence to identify key risks, explain trade-offs, and agree on priorities.
• Lead technical responses to severe or complex incidents, verify recovery, conduct blameless reviews, and follow through on preventive work.
• Work with service owners to establish useful service-level objectives, improve observability, test recovery paths, and make releases safer without unnecessarily slowing delivery.
• Improve on-call practices, reduce unnecessary paging, strengthen handoffs across time zones, and automate repetitive operational work.
• Communicate service health and production risk to engineers, executives, and client-facing teams, including decisions or investments that may be needed.
• Investigate difficult production problems and write or review automation.
