Lead Site Reliability Engineer

JPMorgan Chase & Co.; Dublin; On-site; EUR 120,000 - 180,000; Full time

Job summary

JPMorgan Chase & Co. in Dublin is seeking a Lead Site Reliability Engineer in Infrastructure Platforms. You will be a code-first engineer designing automation, tooling, and observability to keep enterprise-scale platforms reliable and self-healing.

You will own services end-to-end, define SLIs/SLOs, lead incident response, reduce toil through automation, and work AI-native across the SDLC to accelerate delivery while upholding security and cost discipline.

Qualifications

• Solid production coding experience in industry-standard languages (Python, Go, Java, C++, Rust).
• Experience running production systems at scale including on-call ownership and incident response.
• Experience with SLI/SLO or willingness to own it.
• Observability depth: monitoring and telemetry tools (Grafana, Prometheus, Splunk, Datadog, Dynatrace).
• Unix/Linux proficiency and infrastructure automation tooling (Kubernetes, Terraform, CI/CD).
• Strong systems thinking: interfaces, contracts, failure modes at scale.
• Ability to steer AI tools for real engineering work with sound judgment.
• Security-first mindset across design to production.
• Clear, direct communication and calm ownership under pressure.
• Outcome orientation focused on reliability, impact, and cost.

Responsibilities

• Engineer reliability into enterprise-scale platforms by writing production software: automation, control loops, self-healing, and tooling that remove manual operations.
• Build systems around declarative, intent-based design: model the desired state as data in a trusted source of truth and let automation reconcile reality to it, rather than driving change through imperative, one-off scripts.
• Treat data as a first‑class reliability asset: instrument, collect, and reason over telemetry and state data to drive detection, diagnosis, and closed-loop remediation.
• Define and operationalize SLIs and SLOs with stakeholders; implement SLO-based alerting, telemetry standards, and actionable observability.
• Own services end-to-end, taking accountability for reliability, performance, security, and cost, and building operability and observability in from the start.
• Share an on‑call rotation and act as a technical leader during major incidents: drive triage, mitigation, communications, and blameless post‑incident reviews, then engineer the durable fix.
• Drive down toil measurably through automation and better engineering; treat repeated manual work as a bug to be coded out.
• Work AI‑native across the SDLC (AI-assisted development, code review, test generation, incident and root‑cause analysis) with clear validation standards (secure coding, peer review, automated testing).
• Decompose ambiguous reliability problems into clear, executable work for yourself and for AI agents, and integrate the results into coherent, production‑ready systems.
• Set reliability standards and raise the engineering bar across your team and partner organizations.
• Apply security and operational‑risk judgment throughout the engineering lifecycle.

Job description

As a Lead Site Reliability Engineer at JPMorgan Chase in Infrastructure Platforms, you are a code-first software engineer specializing in reliability. You will design and build the automation, tooling, and observability that keep enterprise-scale platforms resilient, and you own those systems end-to-end, including SLIs/SLOs, incident leadership, and toil reduction. You will write software that makes enterprise-scale infrastructure reliable, observable, and self-healing. You will work AI-native, using AI fluently across the software development lifecycle to build faster, respond to incidents quicker, and engineer away manual operations, while retaining full accountability for correctness, security, reliability, and cost.

Job Responsibilities

• Engineer reliability into enterprise-scale platforms by writing production software: automation, control loops, self-healing, and tooling that remove manual operations rather than institutionalise them
• Build systems around declarative, intent-based design: model the desired state as data in a trusted source of truth and let automation continuously reconcile reality to it, rather than driving change through imperative, one-off scripts
• Treat data as a first‑class reliability asset: instrument, collect, and reason over telemetry and state data to drive detection, diagnosis, and closed-loop remediation
• Define and operationalize SLIs and SLOs with stakeholders; implement SLO-based alerting, telemetry standards, and actionable observability
• Own services end-to-end, taking accountability for reliability, performance, security, and cost, and building operability and observability in from the start
• Share an on‑call rotation and act as a technical leader during major incidents: drive triage, mitigation, communications, and blameless post‑incident reviews, then engineer the durable fix
• Drive down toil measurably through automation and better engineering; treat repeated manual work as a bug to be coded out
• Work AI‑native across the SDLC (AI-assisted development, code review, test generation, incident and root‑cause analysis) with clear validation standards (secure coding, peer review, automated testing), so speed never compromises correctness
• Decompose ambiguous reliability problems into clear, executable work for yourself and for AI agents, and integrate the results into coherent, production‑ready systems
• Set reliability standards and raise the engineering bar across your team and partner organizations
• Apply security and operational‑risk judgment throughout the engineering lifecycle

Required Qualifications, Capabilities, and Skills

• Solid production coding experience in an industry-standard language (e.g. Python, Go, Java, C++, Rust): this is a software engineering role
• Experience running production systems at scale, including on‑call ownership, incident response, and designing for reliability and operability
• Experience with SLI/SLO/error‑budget practice, or clear aptitude and appetite to own it
• Observability depth: white‑box/black‑box monitoring, SLO-based alerting, and telemetry, using tools such as Grafana, Prometheus, Splunk, Datadog, Dynatrace, or equivalent
• Experience with *nix and with infrastructure automation and tooling (e.g. Kubernetes, Terraform, CI/CD)
• Strong systems thinking: interfaces, contracts, failure modes, and interactions at scale
• Fluency directing AI tools to do real engineering work, not just autocomplete, with sound judgment on where AI applies and where deep human expertise is required
• Security‑first mindset, integrating risk judgment from design through production
• Clear, direct communication and calm ownership under pressure during high‑severity events
• Outcome orientation: focused on reliability, impact, and cost, not activity

Preferred Qualifications, Capabilities, and Skills

• Networking depth (routing, switching, security, packet/flow analysis) or experience operating network‑adjacent platforms: a strong plus, not a requirement
• Experience across multiple infrastructure domains or programming languages
• Demonstrated ongoing AI skill development (e.g. context/prompt engineering, agent orchestration) and use of AI to redesign workflows for measurable impact
• Prior experience in regulated or large‑scale enterprise environments
• Experience establishing engineering culture
