Most engineering hiring conversations start the same way. What is the stack? How many years of experience? What is the rate? English fluency, if it comes up at all, gets treated as a checkbox at the end of the evaluation rather than a core competency worth examining seriously. That is a mistake that is costing teams more than they realize.
In 2026, software development is a deeply collaborative discipline. Code gets written in sprints, reviewed in pull requests, debated in standups, and shipped based on decisions made across multiple time zones and communication channels. The quality of that communication is not a soft skill sitting adjacent to the technical work. It is embedded in every single part of how modern engineering teams function.
According to a Project Management Institute study, poor communication is the primary cause of project failure one third of the time, and it contributes to nearly half of all unsuccessful projects. In a distributed engineering team that number does not shrink. It grows. And yet most vendor evaluations spend far more time on technical skills than on the communication capabilities that determine whether those skills translate into actual output. This is why English fluency has become the most underrated technical skill in modern software development, and why the rise of bilingual software engineers from Latin America is quietly changing what best-in-class nearshore looks like.
Agile development is built on fast feedback loops. Daily standups, sprint planning, backlog grooming, retros; all of these rituals depend on team members being able to communicate quickly, clearly, and with enough precision to unblock each other without losing a full day to a misunderstanding.
When a developer cannot fully articulate what they are working on, cannot ask a clarifying question without significant friction, or cannot give meaningful feedback during a code review, the agile process breaks down in ways that do not show up in any individual ticket but accumulate across a sprint into missed deadlines and mounting technical debt. Communication in agile development is not a background concern. It is infrastructure. A team with excellent English communication runs faster than a team without it, regardless of how evenly matched their technical skills might otherwise be.
The specific damage that language gaps cause in engineering contexts is underappreciated. It is not just that someone misunderstands a requirement, though that happens. It is that the gap creates a culture of avoidance. Developers who are not confident in their English tend to ask fewer clarifying questions, offer less pushback during planning, and stay quieter during retrospectives.
The result is a team that looks collaborative on paper but is actually running with significant blind spots. Problems that would have surfaced in a standup get buried. Architectural concerns that should have been raised in a review get held back. The silence is not agreement. It is discomfort that eventually shows up in the codebase.
This is one of the core arguments for working with English proficient nearshore developers rather than simply the most affordable option available. The savings on paper can disappear quickly once you account for the cost of rework caused by communication breakdowns that never had to happen.

The rise of bilingual software engineers from Latin America is not accidental. It reflects a deliberate investment made over the past decade, both at the individual level and at the institutional level, in English as a career-defining skill.
Countries like Argentina, Costa Rica, Colombia, and Mexico have all seen significant growth in English proficiency among technology professionals, driven by the clear commercial advantage that English fluency provides when working with US-based clients. Engineers who want to work with the best US companies know that technical skills get you in the door. Communication skills determine how far you go once you are inside.
EF Education First's English Proficiency Index consistently ranks several Latin American countries among the highest in the region for English proficiency, with Argentina regularly leading the pack. These are not marginal improvements. They represent a generation of engineers who grew up consuming English-language technical content, participating in English-language developer communities, and building careers in English-speaking professional environments.
There is a meaningful distinction that matters here. Conversational English gets you through a video call. Professional English fluency is what allows a developer to write a precise bug report, push back clearly on a poorly specified ticket, articulate a technical risk to a non-technical stakeholder, or write documentation that other engineers can actually follow.
The best bilingual software engineers from LATAM bring the second kind of fluency. They can do all of that, and they can do it without the friction that turns a two-minute conversation into a half-day thread of Slack messages trying to figure out what someone actually meant.
When you are evaluating nearshore developers, this distinction is worth probing directly. Ask candidates to explain a technical tradeoff in plain English. Ask them to describe a project failure and what they learned from it. The answers will tell you more about communication quality than any resume ever will.
Beyond literal English fluency, LATAM engineers who have worked with US companies bring something equally valuable: familiarity with US engineering culture. The vocabulary of modern software development, whether that is sprint ceremonies, JIRA workflows, GitHub pull request conventions, or the specific way that product and engineering interact at US-funded companies, is something that takes time to absorb.
Experienced nearshore developers from Latin America have already absorbed it. They are not just English fluent in a general sense. They speak the specific dialect of US tech. That cultural and linguistic alignment compounds over time in ways that traditional offshore arrangements almost never replicate.
If your current hiring or vendor evaluation process does not include a structured English communication assessment, it is worth adding one. Not a grammar test. A practical evaluation of how clearly a developer can communicate under realistic conditions.
Can they explain the last system they built to someone who was not there? Can they describe a tradeoff between two architectural approaches in a way that a product manager could follow? Can they write a clear, concise summary of a code review? These are the real-world communication tasks that determine whether an engineer contributes to your team or creates friction in it.
The best nearshore partners build this assessment into their vetting process as a standard step rather than an afterthought. You can read more about what makes staff augmentation models outperform traditional outsourcing and why vetting depth is one of the biggest differentiators between partners.
One of the less discussed advantages of working with English proficient nearshore developers is how much it improves cross-functional collaboration. When engineering, product, design, and leadership all speak the same language with enough precision to have real conversations, the quality of the decisions coming out of those conversations improves.
This is especially relevant for companies running distributed teams across multiple time zones, where the cost of a single miscommunication compounds because there is no opportunity to resolve it face to face. According to GitHub's research on distributed engineering teams, the highest-performing distributed teams share strong communication norms as a common trait. English fluency is the foundation that makes those norms possible.
For a closer look at how distributed teams stay high-performing as they scale, Blue Coding's post on scaling your engineering team from 5 to 50 covers the operational choices that determine whether a growing team holds together or starts to fragment.
The companies that have figured out nearshore development are not optimizing purely for cost. They are optimizing for value, and they have learned that English fluency is a significant part of what drives the value side of that equation.
A developer who costs 30 percent less but requires twice the management overhead to keep aligned is not actually saving you anything. A bilingual software engineer who operates with full autonomy, communicates proactively, and integrates seamlessly into your team is delivering compounding value that does not show up in an hourly rate comparison.
This is the shift in thinking that separates teams that thrive with nearshore development from teams that cycle through vendors without ever getting the results they were promised. The question is not just who can build the feature. It is who can be a full participant in how your team thinks, plans, and ships.
For a deeper look at why cutting corners on engineering quality always costs more in the long run, Blue Coding's breakdown of the hidden cost of cheap code is worth reading before your next vendor decision.
