Remote Software Developer Jobs in Argentina | Careers at Siblings Software
We're a software development company founded in 2018 in Cordoba, Argentina, serving clients across the Americas and Europe. If you're a Java or Go engineer, a QA automation specialist, a backend or security professional—or you're sharp with React, Python, Node.js, or mobile stacks—we hire for real product work, not bench time. Our developers ship features for payment platforms, healthcare systems, logistics tools, and SaaS products that real users rely on every day.
What makes us different? You join a 30-person engineering team led by Javier Uanini, a software engineer who started coding in 1999 and still reviews architecture decisions alongside the team. You get clear project context, direct client contact when it helps, and room to own your slice of the stack. We've been remote-first since day one: async communication, flexible hours, and a focus on sustainable pace. No fake urgency, no endless meetings. Just solid engineering, modern tooling, and a culture that values honesty over bureaucracy. Check our case studies to see the kinds of products we build, and about us to meet the people behind the code.
Stack snapshot: we ship Next.js and Node for many web products; mobile with React Native; backends in Go, Java, or Python depending on the domain. Read Javier’s full background (payment systems, fintech) or the Spanish careers page if you apply from Argentina.
Why Join Siblings Software?
Work on Real Projects
You won't be stuck maintaining legacy code or working on throwaway prototypes. Our clients are building products that matter—payment gateways handling millions in transactions, healthcare platforms managing patient data, eCommerce systems powering global brands. Every line of code you write has impact.
Learn Continuously
Technology moves fast, and so do we. You'll work with modern stacks—Go microservices, React frontends, TypeScript APIs, cloud-native architectures. We encourage experimentation, provide learning budgets, and support certifications. Your growth isn't just encouraged; it's expected.
Remote-First Culture
Work from anywhere. We've been remote-first since before it was trendy. Our teams span time zones, and we've built processes that make distributed collaboration seamless. Daily standups, async communication, and clear documentation mean you can do your best work on your schedule.
Competitive Compensation
We pay market rates and review compensation regularly. Beyond salary, we offer flexible schedules, learning stipends, and opportunities for long-term projects. Many of our developers have been with us for years, working on projects that evolve and grow.
Diverse Technologies
One month you might be building a React Native mobile app, the next you're optimizing a Go microservice handling millions of requests. We work across the stack—frontend, backend, mobile, DevOps, security. You'll never get bored, and you'll build a portfolio that stands out.
Transparent Communication
No corporate speak, no hidden agendas. We tell you what projects are about, what challenges you'll face, and what success looks like. You'll work directly with clients, participate in architecture decisions, and see the impact of your work. Your voice matters here.
What It's Like to Work Here: One Developer's Path
We asked a senior engineer who joined us several years ago to describe how his role evolved. Here's his story—unedited—so you get a real sense of the work and the team.
I came in as a backend developer focused on Java and Spring. The first project was a fintech client: we were extending a payment reconciliation system and improving API reliability. I had a clear scope, a small team, and a tech lead who actually reviewed code and cared about design. No "just ship it" pressure—we had time to fix tech debt and write tests.
After about a year I moved to a different engagement: a logistics platform. That one was Go and Postgres, event-driven. I hadn't used Go in production before, but the team was supportive and I had room to learn. We did proper code reviews, kept docs up to date, and the client was involved in sprint planning. I could see how my work tied to real business metrics—on-time delivery, warehouse throughput—which made the job feel meaningful.
What I didn't expect was how long people stay. Several of my colleagues have been here for three or four years, on projects that evolved from MVP to scale. We're not a revolving door. If you're looking for a place where you can grow into ownership and work on products that aren't throwaway prototypes, this is it.

A Second Perspective: From QA to Frontend Lead
Every career path here looks different. We asked another team member to share how her role evolved from QA automation to frontend ownership.
I joined Siblings in early 2020 as a QA automation engineer. My first engagement was with a healthcare client building a patient intake platform. The codebase was React and Node.js, and my job was writing end-to-end tests with Cypress and maintaining the CI pipeline. It was the first time I worked in a team where QA was genuinely treated as part of engineering, not a bottleneck.
About eight months in, the frontend developer on the project left, and I offered to pick up some of the React work while we hired a replacement. I had dabbled with React before, but never in production. The team supported the transition: code reviews were thorough, and the tech lead paired with me on the trickier components. Within a few months I was handling the full frontend, still running the test suite, and shipping features every sprint.
Today I lead frontend on a fintech engagement. We build the merchant dashboard that our client's customers use to track transactions and reconcile payments. The stack is Next.js deployed on Vercel, with TypeScript end to end. I still write Cypress and Playwright tests because I believe quality starts with the person who writes the code. My path from QA to frontend lead happened because Siblings gave me room and trust to grow.
