Site Reliability Engineer IV

ExpertVoice is seeking a Site Reliability Engineer IV to set the technical direction for running, automating, and scaling its platform. The role owns production systems end-to-end, leads incident response and architecture work, and advances AI and automation in partnership with infrastructure, developer platform, and security teams.

Responsibilities:

• Lead incident response for complex outages: dig past surface symptoms to true root cause across logs, metrics, trends, and database behavior, drive resolution under pressure, and turn findings into durable fixes and better runbooks
• Participate in the on-call rotation: a full week at a time, shared with three other engineers, so on-call comes around  every fourth week
• Debug and troubleshoot across the stack, including code from other teams, and ensure the team’s work stays documented and maintainable
• Own CI/CD: keep build and deploy pipelines fast and trustworthy, with deploys and rollbacks that any engineer can run
• Own systems end-to-end (architecture, design, optimization, and long-term maintenance), accountable for reliability and performance at scale
• Champion AI and automation across our operations: automate away repetitive operations work and the one-off manual steps that never got fixed, and build the tooling and prototypes that prove what's possible
• Lead architecture discussions and design reviews, and drive adoption of new technologies and patterns
• Partner across infra, dev platform, and security, strengthening those areas rather than working around them
• Set the technical vision and architectural runway: a forward technology plan (debt and investment) that keeps the team ready to deliver what’s next
• Mentor engineers and raise the technical bar across the team

Requirements:

• 10+ Years SRE/DevOps/systems experience with a track record of owning and architecting production systems at scale
• Strong coding ability across the stack (Python, Go, or Java; comfortable in Bash)
• Deep Linux and networking expertise (TCP/IP, DNS, HTTP/TLS) and the ability to design for performance at scale
• Strong AWS, container (Docker), and infrastructure-as-code (Terraform) experience
• A track record of setting technical direction and driving an architectural plan to execution
• Strong critical-thinking and troubleshooting instincts: able to work from symptoms to underlying cause in complex, ambiguous systems rather than stopping at the surface
• An excellent communicator who builds technical trust and aligns a team behind a direction
• Prior architect or tech-lead experience, formal or informal
• A software development background, with firsthand understanding of how the software you support is built
• A prior hands-on software engineering role
• Container orchestration in production (e.g., Nomad, Kubernetes)
• Built AI-assisted tooling or platform automation that others adopted
• Security and operational-hygiene depth; exposure to PCI or similar frameworks a plus
• Comfort spanning modern cloud and older, established technologies
• Bachelor's degree in CS, Computer Engineering, or related field, or equivalent experience
