Will AI Replace Support Engineers?

‍

AI Support Engineers and other AI agents are changing how teams work, but not without raising fundamental questions.

How will AI impact jobs? Where should professionals lean into distinctly human strengths?

At RunLLM, we’ve asked these same questions. Spoiler: we think it improves support engineering jobs rather than replaces them. But there’s a counterargument worth inspecting.

A developer friend — let’s call him Chad — recently said, “Support engineers are the perfect targets for being replaced by AI.” Yes, Chad can be snarky.

Chad’s argument goes like this:

• Support engineers are proxies: Their job is to shield software engineers from customers.
• Support engineers are filters: They triage the easy 80% of customer issues and escalate the 20% that actually matter.
• AI is perfect for proxying and filtering: It’s always available, never gets tired, and doesn’t mind answering the same question for the tenth time.

Snark aside, it’s worth unpacking what Chad gets right—and what he completely misses.

What AI Can Do Well

In fairness to Chad, parts of the support engineering role are highly automatable. For example:

• Repetitive troubleshooting: Investigating known configuration issues or software compatibility bugs
• Ticket analysis and routing: Reviewing logs, categorizing issues, identifying known patterns, and escalating edge cases
• Product onboarding and clarification: Guiding users through setup, pointing to documentation, and reinforcing best practices

AI handles these kinds of tasks well, tirelessly, patiently, and consistently. So yes, Chad has a point. These parts of support are being automated, and they should be. That’s not a threat. It’s a relief.

Where Humans Stay Indispensable

What Chad misses is what happens after the first triage — the part of support engineering that’s less about fixing and more about understanding. AI might know what was asked. Humans know why it was asked, and what it means in context.

Here’s where human support engineers continue to lead, and why that still matters.

1. Navigating high-stakes, emotional moments: When customers are stressed or frustrated, they don’t just need an answer—they need to feel heard. Humans calm tension and build trust.
2. Adapting on the fly: Every customer is different. Every issue is a little weird. Humans can pivot mid-conversation, explore tangents, and shift as things evolve.
3. Turning insights into impact: AI can surface patterns and pain points—but prioritizing them, interpreting the nuance, and sparking change still depends on people.

These are not just human soft skills. They’re core to strategic customer success, and they don’t become obsolete with a new model release.

The Hybrid Future of Support Engineering

Modern AI Support Engineers, like RunLLM, are already doing more than people realize.

They can flag uncertainty and modulate tone. They can detect when a user sounds frustrated or confused. And because they're fast, consistent, and judgment-free, users actually ask more questions than they would in a forum or to a support person — including things they might otherwise be too shy to ask.

That’s a big win for learning and scale. But there are still limits, especially when context lives outside the documentation. AI doesn’t know what’s planned but not yet shipped. It doesn’t reason across long-term relationships, or weigh tradeoffs the way humans do. And it rarely catches the subtle signal when a customer hints at something bigger. Humans still bring the context and judgment needed to connect the dots.

So the future isn’t about AI replacing support engineers. It’s about evolving the role. Let AI handle the volume and repetition. Let people focus on the strategic, the interpersonal, and the uncertain.

That’s how support becomes more scalable and more human.

The Opportunity Ahead

Support engineering, accelerated by AI, is evolving quickly.

AI Support Engineers now handle the mundane, high-volume tasks: triage, routing, basic troubleshooting, and doc lookups. That shift creates a powerful opportunity.

An opportunity for support teams to reclaim time and redirect it toward what matters most:
building stronger customer relationships, driving product and system innovation from AI-surfaced insights, and shaping winning strategy.

The best support engineers won’t be replaced. They will be freed to focus on higher-leverage work and amplified by the AI alongside them.

The companies that adapt will be the ones that win.

This isn’t AI versus humans. It is AI with humans, each doing what they do best.
