Hiring engineers in the US takes 4-6 months, costs $150K+ per senior developer, and annual turnover hits 30%. Meanwhile, your roadmap lags, critical features wait, and competitors close the gap.
4-6 months from job posting to a productive developer. Your roadmap can’t wait. You need capacity now, not next quarter. Every week without developers means lost revenue and unlaunched features.
Senior engineers in the US: $140K-$180K base + equity + benefits = $200K + TCO. Juniors with 2 years of experience ask for $100K. Your burn rate explodes while competing with Big Tech for the same limited talent pool.
You finally hire someone. 2-3 months before they are productive. By then, you’ve lost momentum and your internal team is exhausted from onboarding while putting out fires. The opportunity cost is brutal.
Outsourcing to Asia or Eastern Europe: 8-12 hour timezone gaps, midnight meetings, and async workflows that kill iteration speed. A critical bug takes 24 hours to resolve because they are asleep when your production fails.
We provide full senior engineering teams from LATAM (Colombia, Mexico, Argentina) that work in your timezone (EST/PST compatible), are fluent in English, and have a proven track record of building products for US tech companies and supporting local operations.
Senior engineers specializing in React, Next.js, TypeScript, and Tailwind CSS. Expertise in design systems, state management (Redux, Zustand), performance optimization, and accessibility (WCAG). They work directly with your product and design teams using Figma, Storybook, and your specific toolstack.
Backend developers in Node.js, Express, NestJS, GraphQL, and REST APIs. Expertise in microservices, event-driven architectures, database design (PostgreSQL, MongoDB), caching (Redis), and message queues (RabbitMQ, Kafka).
Python engineers for data pipelines, ETL workflows, MLOps, and backend services. Stack: FastAPI, Django, Airflow, dbt, Pandas, Spark. Integration with data warehouses (Snowflake, BigQuery) and orchestration of complex workflows.
DevOps engineers with expertise in AWS, Azure, GCP, Terraform, Kubernetes, Docker, and CI/CD (GitHub Actions, GitLab CI). They implement observability (Datadog, New Relic), security hardening, disaster recovery, and cost optimization.
Mobile developers specializing in React Native for iOS and Android. Cross-platform development with shared codebases, native modules when required, and seamless backend API integration.
We deeply understand your tech stack, product roadmap, engineering culture, and skill gaps. We identify the ideal squad profile with the precise seniority and technology mix required.
You coordinate direct technical interviews with our proposed candidates. Evaluate coding skills, system design, English proficiency, and cultural fit before making any commitment.
Your squad gains access to GitHub, Jira, Slack, AWS, and your existing tools. A dedicated Tech Lead is assigned as a single point of contact, participating in standups and sprints from day one.
The squad delivers features in sprints according to your cadence. We track velocity, code quality metrics, and continuous feedback loops. Flexible scaling (up or down) with only a 2-week notice.

"We needed to scale DevOps without hiring full-time in the US. Simphony provided 2 senior engineers specializing in Terraform and Kubernetes, ready in 8 days. They migrated 60 microservices to EKS in 4 months. Same Miami timezone, impeccable communication."
"We hired a data engineering squad to build our data warehouse on Snowflake. 3 Python/Airflow engineers who already knew the stack inside out. Within 3 months, we had ETL pipelines processing daily records."
"They developed Deprisa’s current website using a modern stack. Today, they continue to support us with critical cloud migrations and SecOps security. We are extremely satisfied with their work."
"We needed a complete rebuild of our web portal in Next.js. A squad of 4 frontend engineers (React/TypeScript) delivered the MVP in 8 weeks. Lighthouse score 95+, mobile-first, and fully accessible."
From the moment you approve the candidates until they are productively committing code, it typically takes between ten days and two weeks. Our process includes a discovery call to map your specific technical needs, presentation of engineer profiles that match your stack and required seniority, direct technical interviews conducted by you to validate skills and cultural fit, and onboarding with access setup for GitHub, AWS, Jira, and other tools in your stack. Most of our clients have a productive squad in less than two weeks, compared to the three to six months a traditional hiring process takes in the United States.
*Timeline may vary for highly complex or scarce profiles; in such cases, we provide an estimated range but do not commit to fixed deadlines.
ll our engineers undergo a rigorous vetting process before becoming eligible for squads. This includes live coding evaluations, system design interviews, and portfolio project reviews. We only accept engineers with at least 3 years of professional experience building production-grade products, most of whom have a background working for US or European tech companies. Additionally, you conduct your own technical interviews directly with candidates before approving them, just as you would with any internal hire. There are no surprises: the level you see in the interview is exactly what you get. If any engineer does not meet expectations during the engagement, we replace them at no additional cost.
The fundamental difference is timezone and communication. LATAM Nearshore means your engineers are in GMT-5 to GMT-3, which is compatible with US Eastern, Central, and Pacific time zones. This allows for synchronous standups at 9:00 AM, real-time code reviews during your workday, and immediate incident response if production fails at 2:00 PM. With offshore teams in India or Ukraine, you face 8 to 12-hour gaps that force async communication, midnight meetings for one side, and 24-hour delays in resolving critical blockers. Furthermore, English proficiency and cultural alignment with US work methodologies are significantly stronger in LATAM compared to other offshore regions.
Squads are dedicated exclusively to your project for the duration of the engagement. We do not share engineers across multiple clients simultaneously. When you assign a squad of four engineers, they work full-time on your roadmap, report to your engineering manager or tech lead, and are available during your full office hours. Think of it as having four remote W2 employees in terms of dedication and availability, but without the overhead of hiring, payroll, benefits, and HR management.
We offer a replacement guarantee at no cost. If an engineer chooses to leave voluntarily or is not meeting performance expectations based on your metrics, we replace them with an engineer of equivalent or higher seniority within a maximum of two weeks. During this transition period, we provide a temporary backfill with another engineer from our bench so you don’t lose capacity while we find a permanent replacement. We also perform structured knowledge transfers when turnover occurs to minimize loss of context. Our historical turnover rate is less than 10% annually—compared to the typical 30% in US tech—so replacements are relatively rare, but they are contractually covered when they do happen.
