Senior Site Reliability Engineer (SRE)

Opportunity

We’re looking for a Senior Site Reliability Engineer to help build and scale a high-impact SRE function. You’ll be a technical leader on a team responsible for improving system reliability, reducing operational toil, and establishing best practices across engineering.

In this position, you’ll design how reliability works in UJET, influence engineering decisions, and build the tooling and processes that make production safer and more predictable.

Responsibilities

Lead efforts to improve system reliability, scalability, and performance across critical services

Define and implement SLIs/SLOs and error budgets, and use them to guide engineering priorities

Design and develop observability systems (metrics, logging, tracing, alerting) that produce actionable alerts and data.

Lead complex incident response, acting as incident commander when needed

Conduct postmortems focused on systemic causes rather than individual fault, and ensure corrective actions from those reviews are completed.

Identify and eliminate toil through automation, tooling, and improved workflows

Partner with product and platform teams on architecture decisions, production readiness, and designing systems that recover from failure

Build reusable systems and “paved roads” that make it easier for teams to operate their services reliably

Mentor other engineers and raise the overall operational maturity of the organization

Requirements

6-10+ years of experience in SRE, infrastructure, or backend systems engineering

Demonstrated experience of owning reliability outcomes for complex, distributed systems

Strong experience with cloud infrastructure (AWS, GCP, or Azure) and production-scale systems

Deep understanding of observability, incident management, and system performance

Proficiency in at least one programming language (e.g., Go, Python, Java) with a focus on automation and tooling

Able to change how other teams work without having managerial authority over them

Strong competency in making clear decisions during incidents by following a defined process without reacting emotionally.

Stand Out Qualifications

Experience building or scaling SRE practices (SLOs, incident frameworks, on-call models)

Kubernetes/container orchestration experience

Infrastructure as Code (Terraform, etc.)

Experience with high-growth or scaling systems

Background in performance engineering or capacity planning

Success Criteria

Critical services have clear, meaningful SLOs that drive engineering decisions

Alerts are actionable; irrelevant alerts are reduced; on-call workload is manageable.

Incidents are handled efficiently, and repeat issues decline over time

Engineering teams adopt reliability best practices with minimal friction

Toil is actively reduced through automation and better system design

Annual US Hiring Range: $140,000 - $180,000

*A candidate’s actual placement within this range will depend on geographic location, work experience, education, and/or skill level.
