Platform Engineer, DevOps Engineer or SRE?

Hiring guidance

Start with the scope

Hiring managers often conflate these titles because the underlying technical work overlaps across infrastructure and software delivery. A DevOps engineer focuses on the delivery pipeline to help developers ship code faster. Their core task is clearing blocks in CI/CD workflows so teams maintain velocity. If you need someone to manage Jenkins, GitHub Actions, or container orchestration setups, look here.

A Platform Engineer builds internal products for other developers. They create abstractions that simplify complex cloud tasks so the rest of your engineering staff does not need to become networking experts. Think of this role as internal product management for developer tools. This is a builder role that requires software development discipline, not just scripting ability.

SRE roles focus on service reliability and production stability. Their primary mandate is defining and maintaining service level objectives for your live applications. An SRE acts as an engineer who treats operations as a software problem. If your business suffers from frequent outages or requires high availability, hire an SRE to engineer systems that resist failure.

Hiring guidance

Tooling vs Engineering

Ask if they write code to solve operational problems. A candidate who only knows how to configure existing tools via a dashboard is a sysadmin, not an engineer. You want people who treat infrastructure as code by writing maintainable, versioned scripts that automate system state.

Hiring guidance

Incident ownership

Ask for an example of a recent production failure they managed. Listen for how they identified the root cause and whether they implemented automated remediation. A weak answer describes manual fixes. A strong answer describes a change to the system design that prevents the error from recurring.

Hiring guidance

Abstraction trade-offs

Ask about their process for deciding when to build an internal tool versus buying a third party product. An effective engineer evaluates maintenance cost, team capacity, and specific business needs. Avoid candidates who choose complex custom builds just to add a project to their resume.

Hiring guidance

Deployment safety

Ask how they handle failing deployments in a live environment. Look for understanding of canary releases, traffic shifting, and automatic rollbacks. They should explain how they measure user impact during a rollout and what signals trigger an immediate revert.

Evidence to bring into the hiring conversation

Look for talent in organizations that prioritize high frequency deployment cycles. People coming from companies that manage massive microservice architectures often understand the necessity of automated testing and stable internal platforms. Target engineers who contribute to open source infrastructure tools or participate in community discussions about scaling systems.

Search for individuals with prior experience as full stack developers who transitioned into infrastructure roles. These individuals understand the developer experience because they have spent years dealing with broken build systems. Their motivation usually stems from a desire to reduce cognitive load on their peers by simplifying how code travels from the laptop to the production cluster.

Hiring guidance

Problems worth catching early

Hiring based on certification lists rather than problem solving experience. A certification proves they passed a test, not that they have operated a service under actual production pressure.

Expecting one person to cover every aspect of infrastructure. Expecting a single hire to handle cloud networking, security, CI/CD, and site reliability is unrealistic and leads to burnout.

Ignoring the internal product aspect of the job. Hiring a candidate who treats infrastructure as a set of rules to enforce rather than a service to support developers will cause friction with your product teams.

Hiring guidance

Decisions to make before the search

Start by defining your primary bottleneck. Are you struggling with slow build times, frequent production outages, or developer frustration? Choose the role based on that specific need rather than hiring a generalist to do everything.

When interviewing, focus on the trade-offs they made in past projects. Ask why they chose a specific cloud service or why they moved away from a legacy orchestration setup. The quality of their reasoning matters more than the specific tools they named.

Define clear boundaries for who owns what in production. If you hire an SRE, ensure they have the authority to halt deployments that do not meet your reliability standards. Without clear mandate, they cannot enforce stability.
