Senior Manager, Site Reliability Engineering (SRE)

UJET

About The Position

We’re looking for a Senior SRE Manager to build and lead our Site Reliability Engineering function from the ground up. You’ll hire and develop a high-impact team of SREs, define how reliability is engineered across the company, and partner deeply with product and platform engineering to ensure our systems are scalable, observable, and boring—in the best way possible. This is a hands-on leadership role: you’ll set strategy, build processes, and still know what’s actually going on in production.

Requirements

8+ years in SRE, infrastructure, or platform engineering, with 3+ years managing managers or senior ICs
Experience building an SRE team or function from scratch (or significantly scaling one)
Deep knowledge of modern cloud infrastructure, distributed systems, and observability
Strong opinions about what SRE is and is not - and the judgment to apply them pragmatically
Proven ability to collaborate with product and engineering leaders without becoming the “department of no”
Calm, decisive leadership during incidents (the person people want on the conference call)

Nice To Haves

Experience at a high-growth or post-Series B/C company
Background in platform engineering or internal developer tooling
Familiarity with compliance or regulated environments

Responsibilities

Build and lead a new SRE team, including hiring, onboarding, and career development
Define and implement SRE best practices: SLIs/SLOs, error budgets, incident management, on-call models, and postmortems
Establish clear operational ownership between SRE and product engineering teams
Drive reliability as a feature, balancing velocity and stability with data—not vibes
Reduce toil through automation and self-service platforms
Design and evolve incident response, escalation, and learning loops (no blame, lots of learning)
Partner with engineering leaders to influence architecture, capacity planning, and launch readiness
Own reliability metrics and communicate risk and performance clearly to technical and executive audiences
