Senior Software Developer — DFX5
? [Hybrid] · Full-time
About the role
At DFX5 we build edge technology that moves our clients' businesses forward. We're looking for a Senior Software Developer to design, build, and ship high-quality software that solves complex, real-world problems for some of the largest companies in Latin America and beyond. You'll own features end to end — from architecture and coding through testing, deployment, and iteration — and set the technical standard for the teams around you.
This is a senior, high-ownership role for an engineer who writes clean, scalable code, makes sound architectural decisions, and lifts the whole team through mentorship and example.
What you'll do
Design, develop, test, and deploy robust, scalable software solutions across the full stack (or your area of depth).
Translate business and product requirements into solid technical designs and well-structured code.
Make and document architectural decisions, weighing performance, scalability, security, and maintainability.
Write clean, testable,



well-documented code and champion engineering best practices (code reviews, CI/CD, automated testing).
Collaborate closely with product, design, QA, and project management to deliver features on scope and on time.
Troubleshoot, debug, and optimize applications for performance and reliability in production.
Mentor mid-level and junior developers, and raise the technical bar across the team.
Stay current with emerging technologies and bring practical improvements back to the team.
What you bring
6+ years of professional software development experience, including senior-level ownership of significant features or systems.
Strong proficiency in one or more modern languages and frameworks (e.g., Java, C#/.NET, Python, Node.js, Go, JavaScript/TypeScript, React/Angular — per DFX5's stack).
Solid experience with relational and/or NoSQL databases, API design (REST/GraphQL), and microservices architectures.
Hands-on experience with AWS cloud
