Hire a Senior Back-End Developer to Own Your APIs, Integrations, and Data

Get a full-time, senior back-end developer from Latin America, embedded in your team at $3,500 to $4,500 per month, all-in. Working your hours, month-to-month, nothing owed until you hire.

TRUSTED BY MARKETING AGENCIES ACROSS THE U.S.

Most teams can find someone to build a landing page. Far fewer have someone who can build what sits behind it: the API that pushes form fills into the CRM, the nightly job that syncs ad spend into the warehouse, the login on the customer portal, the database that has to stay fast when a campaign spikes. When teams go looking to hire a back end developer, that is the gap they are trying to close.

When we ran our agency, the projects that ran late rarely had a design problem. They had an integration nobody owned: the CRM sync that silently dropped records, the automation chain that fell over at volume, the reporting pipeline built in a weekend and never touched again. Hiring a senior back-end developer full-time in the US is expensive, and the good ones have offers. A senior back-end developer from Latin America, embedded in your team on your hours, gives you that ownership at $3,500 to $4,500 per month, all-in.

What a senior back-end developer actually owns

A senior back-end developer builds the server side of your products and your marketing stack: REST and GraphQL APIs, the services behind web and mobile apps, integrations between your CRM, marketing automation, billing, and data warehouse, authentication and permissions, background jobs and queues, and the database schema under all of it. Most of the developers we place work in Node.js, Python, or PHP with frameworks like Express, Django, FastAPI, or Laravel, against PostgreSQL, MySQL, or MongoDB, on AWS, GCP, or Azure. They also own what nobody thanks you for until it breaks: query performance, caching, monitoring, and the security posture that keeps a customer portal out of the headlines.

What separates senior from junior is judgment about failure. A junior developer can make an integration work. A senior one asks what happens when the API times out, when two systems disagree about the source of truth, when a webhook fires twice, and when the table has ten million rows instead of ten thousand, and designs for it up front.

Back-end, full-stack, front-end: which seat you are actually hiring

Whether the posting says backend, back-end, or server-side developer, the seat is the same, and it differs from the other two titles. A front-end developer owns what the user sees: the interface, the components, browser performance. A back-end developer owns what the interface talks to: the APIs, the data, the integrations, the security. A full-stack developer covers both, usually with a stronger side, and is the right call when you have one product and need one person who can ship a feature end to end.

Hire back-end specifically when the hard part lives in the data and the integrations rather than the screen: several systems that must agree, customer data or payments, performance problems a new theme will not fix, or front-end people blocked on endpoints. The common mistake is hiring a full-stack generalist for a back-end-heavy role and getting someone excellent at the interface and adequate at the database, which is how a nightly sync ends up taking six hours. The honest flip side: if you need a marketing site, a few forms, and a CRM connection a native integration already handles, you do not need this seat yet, and we will say so on the call.

A note on what is missing from this table. Our 2026 Latin American Marketing Salary Report sources a fully loaded US cost for nine roles, and back-end developer is not one of them. Borrowing a number from an adjacent role would be a guess dressed up as data. The number we control is our own: a full-time senior back-end developer through Talent Scout runs $3,500 to $4,500 per month, all-in, in line with the up to 70% savings our clients see across roles against the fully loaded US cost. We will add a sourced line for this role once we have it.

Why nearshore works for back-end work specifically

Back-end work is full of decisions that cannot wait a day. An integration breaks at 9am and sales stops getting leads. A product manager needs to know this afternoon whether an endpoint can support the feature. Our developers in Brazil, Colombia, Argentina, and Mexico are online for your entire business day, sit in your standup and code reviews, and pair with your front-end developer live instead of trading pull request comments across a twelve-hour gap. That is the practical case for nearshore over offshore, which we lay out in nearshore vs offshore staffing, and it matters more here than in most roles, because back-end failures are quiet and compound in the data.

How hiring works

Tell us your stack, the systems the role needs to integrate, and what this person will own. We source and vet from our Latin American network, screening for roughly five-plus years of hands-on experience in back-end development and 8+/10 English fluency, and we present the first round of candidates in 10 days. You interview and choose. We handle employment, compliance, contracts, and cross-border payments, so you manage the developer like any other member of your team. It is month-to-month, nothing is owed until you hire, and every placement includes free replacements at any time. It is the same embedded model behind marketing staff augmentation and outsourced marketing.

When to hire a back-end developer

Hire one when your CRM, marketing automation, billing, and reporting no longer agree and nobody owns the reconciliation; when front-end developers wait on endpoints more than they build; when customer data or payments run on infrastructure built by whoever was available; when a no-code automation stack has grown past what it can safely carry; or when performance problems keep getting patched instead of fixed. If your business depends on systems talking to each other every day, that function needs a permanent owner.
