Technical Debt and Employee Retention: Why Engineers Walk Away

In part 1 of the Technology Debt series, we explored how technical debt affects business. Now the problem is even more personal: What would that debt do to the team you’re trying to build?
Because their core systems can break down long before the business does.
Many experienced engineers will make a decision before accepting the offer when they see that happening.
Why Technical Debt Can Drive Engineers Away
Senior technical talent is not just assessing salary, job title or benefits.
They are also evaluating the environment they will be in.
A developer joining a business with modern infrastructure, documented systems, sensible architecture, and a defined technology path can see a chance to build. A developer joining an environment that is stuck with old patches, workarounds, unidentified dependencies, and recurrent outages has a different experience.
A maintenance job.
This distinction is important for technical debt and staff retention.
Senior engineers like to have challenging problems. They’re not always going to want to spend their next three years trying to solve the same problem that should have been solved five years ago.
This is especially important when recruiting Senior Software Engineers. The better the candidate, the more questions they will ask about what sits behind the job description.
Your Technology Stack Is Part of Your Employer Brand
Your company’s reputation as an employer of choice doesn’t just end with your careers page.
Candidates build an impression based on the questions/answers they receive and the technical environment they experience during the hiring process.
A company might be innovative. But if the engineering team spends most of its time keeping a fragile legacy application alive, experienced candidates will see the contradiction.
The same is true for retention.
A well-rounded engineer hired to modernize systems can get frustrated when all the improvements he proposes depend on undocumented systems, outdated architecture, budget constraints, or the fear of touching something that will break.
However, the outcome is not necessarily immediate resignation.
At times it is more silent.
Staff do not suggest further improvements. They become more disengaged. They begin to consider other jobs. After some months, one of the company’s investments goes astray.
That’s where Technical Debt and Employee Retention come together.
How Candidates Analyze Your Stack Before They Accept
The hiring process provides candidates with greater information than employers may realize.
Experienced technical candidates will ask questions that will show you the environment they’re looking for.
- What they notice in interviews
- What percentage of engineering effort goes to maintenance versus new development?
- What percentage of the current infrastructure can be considered legacy?
- What is the Technology Roadmap?
- How are technical decisions made?
- Do they have dedicated time to refactoring and making technical improvements?
- What happens when an engineer comes across a big architectural issue?
- What level of autonomy does the engineering team have?
- Why is this position open?
The answers matter.
So does the hesitation before them.
A candidate does not have to be in your internal systems to understand that you have no answers as to how you are going to deal with technical debt.
- What they research beforehand
Candidates also have access to information outside the interview.
They’ll check out your products, engineering team, technology in your environment, public job postings, employee reviews, and the type of technical work your company seems to be doing.
They are just trying to get an answer for a simple question:
- Will I be building here, or will I spend my time fixing what was never built properly?
Why Legacy Systems Can Shrink Your Candidate Pool
Technical debt is more than just an unhappy employee problem.
It may impact the people applying.
Suppose that you’re looking for an accomplished software architect. You require someone who can make a long-term architectural decision, who can lead engineering teams, and who can enhance scalability.
Now picture that candidate discovers there are multiple legacy systems in the environment, sparse documentation, a few brittle integrations, and years-overdue modernization.
They can still go for the interview.
They might even be interested in the challenge, too.
However, if the organization is not able to provide an answer as to how they will address those issues, the opportunity changes.
The candidate is no longer considering just the job. They are trying to weigh the risk.
This is one of the lesser-known costs of technical debt in IT hiring. The best candidates might opt themselves out before your recruitment team even reaches out to them.
This reduces the pool.
The smaller the pool, the more difficult, slower, and more dependent hiring becomes on finding someone who agrees to terms that aren’t appealing to others.
What Employers Should Tell Candidates About Technical Debt
The answer is: Do not deny the problem.
Smart engineers can spot this kind of overselling in most cases. If the actual situation after joining is very different from what was described, it can easily and quickly ruin trust.
Transparency can work in your favour.
If the organization is aware of the need for modernization of its platform, say so. If the first year is an infrastructure stabilization year before introducing a major new development, explain that. If leadership has allocated resources to solve the technical debt, discuss that.
There is a difference between saying:
“Our systems are a mess.”
and saying:
We know where the technical debt is, we know what it is costing us, and this role has the mandate to help fix it.
The second one tells a senior engineer that there is a problem. But it also explains that there is a plan.
It can make a difference to the conversation about technical debt and employee retention. The aim is not to make the environment sound perfect. It’s to get the opportunity fair.
How Lambert Nemec Group Can Help
A job description isn’t the only thing required when hiring someone into a tech environment with significant technical debt.
The position must be presented truthfully. Candidates must have an awareness of what they are walking into, what they will be expected to change, and what support they will have in order to make those changes.
That’s where a clear hiring approach matters.
At Lambert Nemec, we can help you work through the technical realities before you put yourself out there to market. That means knowing the environment, shaping the mandate and making the opportunity to invite people who have the capacity to do the job, not to candidates who find themselves caught off guard upon arrival.
If your technical debt is causing more pain in your next IT hire than value, let’s talk about what that job is and how to fill it with the right people.
