Why hire Erlang developers based in Latin America?
Work synchronously with Erlang developers in the same or overlapping US time zones. Real-time collaboration, no async tax.
What are Erlang developers?
An Erlang developer builds distributed, fault-tolerant systems where uptime and concurrency are non-negotiable. They write backend services in Erlang, a language designed from the start for telecom-grade reliability, and they own the architecture decisions that keep those systems running under load.
Day-to-day, that means designing supervision trees, managing message-passing between lightweight processes, and engineering systems that recover from failures without human intervention. Erlang developers typically work alongside infrastructure and backend teams, and they often reach into the OTP (Open Telecom Platform) library to build production-grade applications faster.
What separates a strong Erlang developer from a competent one: real production experience with the BEAM virtual machine, a track record of designing systems that handle millions of concurrent connections, and the judgment to know when Erlang is the right tool and when it carries more overhead than the problem warrants.
Why hire Erlang developers?
Erlang developers build the systems that can't go down. If your product handles real-time messaging, financial transactions, or telecommunications routing, a gap in Erlang expertise shows up directly in your reliability metrics and your on-call rotation.
The hiring problem is real: Erlang is a niche discipline. Most US-based senior engineers with BEAM production experience either work at WhatsApp, Ericsson, or similarly large operators, or they command salaries that push them out of reach for a mid-market engineering team. The talent pool is genuinely thin onshore.
Latin America's talent pool includes engineers who built their Erlang and BEAM experience on telecom infrastructure projects in Brazil, Colombia, and Argentina. Through Revelo, you get a shortlist of vetted candidates within 72 hours and can complete a hire in under 14 days on average. The all-in cost runs 30–50% below comparable US hiring, and you're working with engineers in the same time zones as your existing team.
What does it cost to hire Erlang developers?
For a senior-level Erlang developer, engineer compensation based in Latin America typically runs between $54,000 and $84,000 annually. The all-in cost through Revelo, which covers PEO protections, benefits, and Revelo's margin, lands higher but still well below comparable US hiring.
In the US, senior software developers earn well into six figures, with specialized backend disciplines like Erlang pricing toward the higher end given the small talent pool.
The figures below reflect Revelo Salary Guide data for software developers across the region (US-remote placement data, 2024-2026). Erlang specialists, as a niche backend discipline, sit at the upper end of these bands.
| Level | US Salary Range (Glassdoor 2026) | LATAM Salary Range (Revelo Salary Guide) |
|---|---|---|
| Junior | $80,356–$148,681 | $36,000–$60,000 |
| Mid-Level | $95,782–$156,181 | $48,000–$70,000 |
| Senior | $141,723–$220,394 | $54,000–$84,000 |
These are engineer compensation figures. The all-in cost through Revelo (which folds in PEO coverage, benefits, and Revelo's margin) runs higher but still lands well below US hiring costs. Visit revelo.com/pricing for a role-specific quote.
Why hire in Latin America?
Latin America's Erlang talent pool grew out of real telecom infrastructure work. Countries like Brazil, Colombia, Argentina, and Mexico built out mobile and landline networks over the past two decades using Ericsson equipment and software, and engineers working in that sector developed Erlang skills on production systems. The depth here traces back to the region's industrial history, not a bootcamp trend.
Timezone alignment is especially important for Erlang work. Distributed systems need active monitoring, and incident response can't wait for a morning handoff. Major LATAM engineering hubs sit within 0–2 hours of US Eastern, which means your Erlang engineers are online during your core hours, reachable on Slack, and able to join a production incident call in real time.
English fluency among tech professionals in the region is consistently strong, and engineers based in Latin America who have worked on US-remote teams understand how to operate inside a distributed product organization. Communication overhead stays low.
How to evaluate Erlang developers
Start with concurrency architecture. Ask the candidate to walk you through how they've structured supervision trees in a production system. A strong answer names the specific OTP behaviors they used (GenServer, Supervisor, Application) and explains the failure recovery strategy. A weak answer stays at the conceptual level without connecting to a real system they shipped.
Next, probe BEAM internals. Ask how the scheduler handles process prioritization and what happens to a long-running computation in terms of preemption. Candidates who've debugged performance problems in production know this cold. Candidates who've only used Erlang in tutorials typically can't move past surface-level answers.
Finally, test distributed systems judgment. Give a scenario: two nodes in a cluster lose connectivity mid-transaction. Ask how they'd design for that failure mode and what trade-offs they'd accept. Strong candidates reason through CAP theorem implications and explain what they'd sacrifice. This question separates engineers who've run Erlang in production from engineers who've read about it.
Why expertise matters
Why Erlang Wins for Concurrency and Fault Tolerance
Erlang's process model runs millions of lightweight processes inside a single VM, each isolated from the others. A crash in one process doesn't propagate. The OTP supervision framework restarts failed components automatically, so systems built on Erlang absorb failures by design. For products where five-nines uptime is a real requirement, that built-in recovery pattern is difficult to replicate in other languages.
Erlang vs Elixir: Which Should You Hire For?
Erlang and Elixir both run on the BEAM virtual machine and share the same concurrency and fault-tolerance guarantees. The hiring decision turns on your codebase and team, not the runtime. The table below summarizes the practical differences.
| Factor | Erlang | Elixir |
|---|---|---|
| Syntax | Prolog-influenced, terse | Ruby-influenced, more readable |
| Community and tooling | Decades of production use in telecom | Younger, faster-growing community |
| Talent pool | Smaller, deeper telecom and systems specialization | Larger, broader web and API development background |
| Typical use cases | Telecom network elements, legacy BEAM systems, protocol stacks | Web APIs, real-time apps, Phoenix-based backends |
| Interoperability | Native; Elixir compiles to the same BEAM bytecode | Can call Erlang libraries directly |
| Hire when | Maintaining or extending an Erlang codebase, or building telecom-grade infrastructure | Starting a new BEAM project with a broader hiring pool |
If your codebase is already in Erlang, hire an Erlang developer. If you're starting fresh and concurrency is a requirement but telecom-specific protocol work is not, Elixir broadens your candidate pool without sacrificing the BEAM's reliability guarantees.
Common Use Cases
Erlang appears most frequently in real-time messaging platforms, financial transaction processing, telecom network elements, IoT device management, and online gaming backends where session state needs to survive server restarts. It's also the runtime underneath RabbitMQ, one of the most widely deployed message brokers in enterprise infrastructure.
Companies Shipping Erlang in Production
WhatsApp scaled to over a billion users on an Erlang backend before and after the Meta acquisition. Ericsson uses it throughout its core network equipment. Discord runs significant portions of its backend on Elixir, which compiles to BEAM bytecode and inherits Erlang's concurrency model. Klarna runs Erlang services in its payment processing stack.
When Erlang Is the Wrong Choice
Erlang carries a steep learning curve and a small global talent pool. If your concurrency requirements are modest or your team has no existing BEAM experience, the onboarding cost outweighs the reliability benefits. For CPU-bound workloads like data processing or machine learning inference, other runtimes serve those workloads more efficiently. Choose Erlang when uptime and massive concurrency are load-bearing requirements.

Strong candidates reason through CAP theorem implications and explain what they'd sacrifice. This question separates engineers who've run Erlang in production from engineers who've read about it.
Why Erlang Expertise Matters
Demand for BEAM engineers has expanded well beyond telecom. Real-time messaging platforms, financial clearing systems, IoT device management layers, and multiplayer gaming backends have all pulled Erlang (and Elixir, which runs on the same VM) into production. The hiring market for this skill has tightened because the use cases grew faster than the engineering population did.
For a mid-market company, the staffing gap has direct business consequences. A backend team that can't maintain its Erlang services in-house ends up dependent on one or two individuals who hold all the institutional knowledge. When one of them leaves, the system effectively becomes unmaintainable. That's the risk sitting underneath every under-staffed Erlang codebase.
The supply-demand imbalance also means that US-based Erlang engineers carry significant negotiating power. Mid-market companies routinely lose candidates to larger operators who can pay more and offer stronger equity. Building Erlang capacity through a nearshore model lets engineering leaders close positions without competing in an auction they're likely to lose.
How Revelo Vets Erlang Developers
Every Erlang candidate in Revelo's network passes a five-stage screen before you see their profile, and only about the top 2% of applicants clear it. Erlang candidates are pre-vetted before you ever start a search, so your 72-hour shortlist contains only engineers who've already passed.
The first stage is a profile and AI-assisted review covering work history, project scope, and depth of BEAM production experience. Candidates who clear that move into an English fluency evaluation, assessed for professional communication at the level a US product team expects.
The Erlang-specific technical screen comes next. A senior reviewer probes OTP fundamentals, distributed system design, and BEAM runtime behavior. Candidates then complete a hands-on challenge (a real concurrency or fault-tolerance problem) evaluated for both correctness and design judgment, alongside a soft-skills assessment focused on remote collaboration.
The final stage is a live interview with a senior Revelo technical reviewer who specializes in backend and systems engineering. Candidates who pass all five stages enter the active network. When you start a search, Revelo delivers a tailored shortlist, including candidate profile videos, within 72 hours.
