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
