In recent years, the concept of “ghost engineers” has sparked heated debates in the tech industry. A Stanford researcher coined the term to describe software engineers who do the bare minimum—just 10% or less of the productivity of their median peers. His algorithm, applied to GitHub repositories across hundreds of companies, found that about 9.5% of coders fit this description.
Everyone thinks this is an exaggeration but there are so many software engineers, not just at FAANG, who I know personally who literally make ~2 code changes a month, few emails, few meetings, remote work, < 5 hours/ week, for ~$200-300k.

Here are some of those companies:


But here’s the kicker: the same research revealed that some remote engineers were five times as productive as their peers.
While it’s easy to vilify remote work in the hunt for underperformers, blaming remote setups entirely misses the point. The issue isn’t where employees work; it’s about how companies identify and manage their workforce. Tools like Thareja AI are key to addressing underperformance, not blanket bans on remote work.
The Real Issue: Measuring Performance
As the researcher Yegor Denisov-Blanch pointed out, software engineering is notoriously hard to measure. Traditional metrics like lines of code are misleading—simple fixes can generate thousands of lines, while complex changes may only require one. His algorithm considers factors like maintainability, complexity, and ease of implementation, offering a more nuanced view of productivity.
The real problem arises when companies focus on raw output without understanding context. This lack of clarity fuels the frustration of engineers who feel undervalued for high-quality work, while underperformers fly under the radar.
The Case for Remote Work
Elon Musk, a vocal critic of remote work, has made sweeping changes at Twitter (now X), slashing staff and pushing for an in-office culture. His recent push to eliminate remote federal employees reflects this mindset. But this approach ignores a critical finding in Denisov-Blanch’s research: remote work attracts both the best and worst engineers.
For every so-called “ghost engineer” working remotely, there are superstar coders delivering exceptional results. Why would you throw the baby out with the bathwater? Instead of dismantling remote work, the focus should be on identifying and retaining those high performers while addressing underperformance.
How Thareja AI Can Help
Managing a remote or hybrid workforce doesn’t have to be a black box. With tools like Thareja AI, companies can gain real-time insights into productivity, performance, and contributions:
1. Data-Driven Performance Reviews:
• Track coding activity, project milestones, and impact.
• Reward meaningful contributions, not just visible output.
2. Weeding Out Underperformers:
• Automatically flag patterns of low productivity for review.
• Use metrics that account for quality and complexity.
3. Identifying Superstars:
• Highlight top performers to ensure they’re recognized and retained.
• Provide targeted support to help them thrive in their roles.
4. Transparent Feedback Loops:
• Facilitate open communication about expectations and progress.
• Avoid the perception of favoritism or arbitrary evaluations.
With these tools, organizations can move away from blanket policies like “remote work bans” and focus on building a truly high-performing workforce, regardless of location.
The Bigger Picture
The ghost engineer debate is part of a larger reckoning in tech: how to balance efficiency with empathy. Companies like Twitter have shown that dramatic staff cuts don’t necessarily break systems, but they risk demoralizing teams and stifling innovation.
Remote work, on the other hand, has proven its value. It allows companies to access a global talent pool, reduce operational costs, and improve work-life balance for employees. Abandoning this model based on a minority of underperformers is shortsighted at best.
Instead, the key is to embrace the tools and strategies that make remote work scalable and accountable. By leveraging technology like Thareja AI, companies can ensure every employee—remote or in-office—meets their potential.
A Smarter Approach to the Future of Work
Musk’s push to cut remote engineers reflects an outdated view of productivity. The real issue isn’t remote work itself but the lack of effective systems to evaluate and support employees. The research shows that remote setups harbor both the least and most productive engineers. The solution isn’t to throw out the entire model but to use smarter tools to maximize its benefits.
Tools like Thareja AI aren’t just about tracking activity; they’re about empowering companies to make informed decisions. By identifying ghost engineers and nurturing superstar coders, businesses can create an environment where every team member contributes meaningfully.
In the end, it’s not about where people work—it’s about how we empower them to do their best work. Let’s move past the ghost stories and focus on building teams that truly shine.
