About the role
Senior Software Developer —
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.
The impact you'll have
Your code will power solutions used by leading financial institutions, retailers, telcos, CPG, and mining companies. The systems you build will directly shape whether DFX5 delivers on its promise of edge technology — reliable, scalable, and secure. As a senior engineer, you'll also shape how the team builds, mentoring others and setting standards that ripple across every project we deliver.
