Staff Infrastructure Engineer / Manager, Engineering
Mission
Lead infrastructure projects and mentor others
Tour of Duty
Design infrastructure that becomes critical foundation
About This Job Family
People in this job family build the systems and code that power products. From frontend interfaces to backend services to infrastructure, they design, implement, and maintain the technical foundation that everything else depends on. Good engineering is measured in reliability, scalability, and velocity.
What You'll Do
Infrastructure Engineers build the foundation everything runs on—cloud resources, networking, compute, storage, and the systems that provision and manage them. They operate at the lowest layers of the stack, where reliability and performance directly impact every team. Success means infrastructure that scales, heals, and costs what it should.
- • Lead infrastructure projects spanning multiple domains or teams
- • Design infrastructure architectures that scale and self-heal
- • Mentor engineers on infrastructure thinking and cloud patterns
- • Define infrastructure standards and IaC patterns for teams
- • Drive cross-team infrastructure decisions and migrations
- • Own reliability and cost optimization for critical infrastructure
Every responsibility is an accomplishment waiting to happen. The question is: will you own the outcome, or just do the task?
Manage a Team?
Great managers are practitioners first. The IC responsibilities above are your foundation—the craft you model for your team. Your management responsibilities are additive:
- • Run 1:1s for growth, not status—development conversations, not standups
- • Hire engineers who raise the bar—own the interview process end-to-end
- • Give direct feedback with care—it's how people actually improve
- • Remove blockers—shield the team from chaos so they can ship
- • Watch for burnout and team health—intervene before it's a crisis
Your team's accomplishments are your accomplishments. Help them craft S.M.A.R.T wins—specific, measurable, and ready to stand on their own.
AI as an Accelerator
AI isn't a skill we call out. It's invisible in the accomplishment but easily visible in the velocity and scale of your outcomes. Here's how people in this role are accelerating their work with AI:
- → Designing infrastructure systems
- → Analyzing performance patterns
- → Generating technical specs

The Competencies That Matter
Skills fill your toolbox. Competencies are how you wield them. Three matter most at this level:
1. SOFTWARE ENGINEERING (3) You don't just write code—you design systems. Your technical decisions shape what the team builds.
2. IT OPERATIONS (2) Strong IT Operations skills required at this level.
3. INFORMATION SECURITY (2) Strong Information Security skills required at this level.
The radar shows the full picture. These three are where you need to be undeniable.
Your Journey From Here
Going up? Your next Tour of Duty:
→ Senior Staff Infrastructure Engineer / Senior Manager, Engineering - Infrastructure (L5) "Drive architecture decisions that shape infrastructure strategy"
The L4 → L5 gap is about SCALE and INFLUENCE: • From owning a project → shaping how projects get built • From leading work → leading people who lead work • From shipping features → building systems that outlast you
These are your stretch accomplishments. Start doing L5 work now. When you can prove it with accomplishments, you're ready.
Going sideways? That's valid too.
Up isn't the only direction. It's your career. You own it.
