10 Top Companies for Outsourcing Back-End Development

Finding the right outsourced back-end development company or professionals is crucial. These are the people who will be building the foundation of your entire system.

But with so many outsourcing options out there, from global freelance marketplaces to specialized development firms, it’s hard to know where to start.

This article provides an overview of 10 established companies that offer back-end development services (or can connect you with folks who do). We’ll look at recruitment specialists who can help you find individual developers, as well as full-service firms that handle entire software development projects.

We also cover the types of services you can typically outsource. 

Whether you’re looking to augment your existing team or tackle a complete back-end overhaul, you’ll get a clearer picture of the available options.

Benefits of Outsourcing Back-End Development

Building and maintaining a strong back-end development team in the US is getting harder and more expensive. That’s why more companies are looking at outsourcing as a strategic move, not just a cost-cutting measure.

However, just like any strategy, it comes with its own pros and cons. While there are challenges to work through, like maintaining effective quality control and communication, here’s why it’s gaining traction.

Access to specialized skills when you need them

Here’s a common situation: You need someone with specific back-end expertise—maybe experience with a particular framework or specialized knowledge in areas like API development or database optimization.

Finding this locally often means either:

• Spending months searching for the perfect candidate who might not even exist in your area
• Taking on a full-time hire when you really just need that expertise for specific projects
• Training someone internally, which takes time you don’t have

This is where outsourcing makes a lot of sense. Instead of trying to find a unicorn locally or compromising on the skills you need, you can tap into a broader talent pool that already has the exact experience you’re looking for.

Think of it as having a skilled specialist on call. You get the expertise you need, when you need it, without having to build out an entire in-house team for every specialized skill set your projects might require.

Real cost savings (but not by cutting corners)

The cost advantages of outsourcing development come from two main factors:

First, the economics are just different in many tech hubs around the world. Take Latin America—you can hire exceptional developers there who have worked with major US companies, know all the latest technologies, and deliver outstanding work.

They command lower rates not because they’re less skilled, but simply because the cost of living is lower in their local economies. Our data shows companies typically save 36–56% by working with LatAm engineers and developers while still paying very competitive local rates that attract and retain top talent.

If you’re working with full-service development firms, you get additional savings from their economies of scale. These firms supply everything—development teams and project managers, infrastructure, QA—across dozens of projects and clients. That’s much more efficient than trying to build all that capability yourself, especially for specific projects or technologies where you don’t need a permanent in-house team.

Scalability and flexibility

When you’re working with outsourced developers, you’re not locked into traditional employment structures. Need to quickly add three developers for a major project? You can do that without going through months of US recruitment. Need to scale back after? You can do that too.

Focus on what actually moves the needle

Here’s what often happens with in-house teams: your best developers get pulled into maintenance tasks or small feature updates instead of working on core innovations. With outsourcing, you can build a team specifically for maintenance and routine development, freeing up your local team for strategic initiatives.

Faster time-to-market

When it comes to speeding up development, there are two proven approaches to outsourcing that can dramatically accelerate your timelines:

If your project needs real-time collaboration and quick iterations, nearshore development teams in Latin America are ideal. You’re working in the same or similar time zones, which means your developers are online when you are.

Questions get answered immediately, problems get solved faster, and there’s no waiting overnight for responses.

This is especially powerful for complex projects where you need lots of back-and-forth with your team.

On the flip side, some companies strategically use time zone differences to their advantage. Having development teams across multiple time zones means work can progress around the clock—your Asian team can hand off to your European team, who then hands off to your Americas team. 

The key is matching your outsourcing approach to how your team actually works. If you need tight collaboration and frequent communication, staying within similar time zones usually works better. If you’re working on more independent modules or maintenance tasks, spreading across time zones can help you move faster.

Either way, you’re not spending months trying to hire locally—you can get the right people working on your project within weeks.

Back-End Development Services for Outsourcing

When people talk about back-end development, they often treat it like one big thing. But in reality, it’s a whole ecosystem of different services—and you don’t have to outsource all of them.

The key is identifying which specific capabilities would move the needle for your business goals, whether that’s scaling up your infrastructure, improving performance, or launching new features faster.

Here are the main services you can outsource, either individually or as part of a broader development strategy:

• API development and integration: Outsourcing API development allows for seamless communication between your applications and other software, whether building APIs from scratch or integrating existing ones.
• Database management and optimization: Experts can manage, optimize, and maintain your databases, giving you data integrity, enhanced performance, and efficient storage solutions.
• Performance tuning and scaling: Specialized developers can fine-tune your system’s performance and create scalability, allowing your application to handle increased loads and user demand without lag.
• Server management: Outsourcing companies can handle efficient server management, including setup, monitoring, and troubleshooting, to maintain a robust and reliable infrastructure.
• Cloud hosting solutions: Harness the power of cloud platforms with experts who can migrate, manage, and optimize cloud services tailored to your business needs.
• Quality assurance (QA): Outsourcing QA makes sure that your back-end systems are reliable, bug-free, and functioning optimally before they go live.
• Security implementation: Protect your software with professional-grade security solutions that safeguard against vulnerabilities and comply with industry standards.
• System integration: Seamlessly connect various subsystems and make sure they work harmoniously, improving overall system functionality and user experience.
• Maintenance and support: Continuous maintenance and support services keep your back-end systems up to date, resolve issues promptly, minimize downtime, and enhance productivity.

Outsourcing these services lets you stay agile and tackle complex back-end tasks without overburdening your internal teams.

Final Thoughts

More companies are realizing that traditional approaches to hiring and team building aren’t keeping up with their needs—whether that’s because of skill gaps, budget constraints, or the need to move faster. Outsourcing your back-end development gives you access to the skills you need, cost efficiency, and the flexibility to focus on business growth. 

The key is finding the sweet spot between cost savings and quality. Some companies push to save 70%+ on US salaries by targeting the absolute lowest rates globally. 

They’ll find developers, but they’ll get what they pay for.

The companies that thrive are the ones saving 30–60% while still paying rates that attract the best talent. This approach gives you sustainable savings while building a stable, high-performing remote team.

The difference in mindset is crucial. It’s not about finding cheap labor—it’s about accessing great talent in markets where your budget goes further. When done right, both sides win: companies get exceptional developers at better rates, and developers get competitive compensation for their local market while working with innovative US companies.

This is exactly why we have our entire recruitment team living and working in Latin America. We know the “price of a coffee”—what it actually costs to live there and what salary levels attract and retain the best talent. It’s this on-the-ground knowledge that helps us guide companies to that sweet spot: rates that provide meaningful cost savings while ensuring you get access to the region’s top developers.
