Senior Software Developer

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 services and CI/CD pipelines.
• Strong grasp of software design patterns, data structures, algorithms, and the full SDLC.
• Experience with version control (Git) and Agile delivery (Scrum/Kanban).
• Excellent problem-solving skills and the judgment to balance speed with quality.
• Fluent English; additional languages a plus.

Education & certifications

• Bachelor's degree in Computer Science, Software/Systems Engineering, IT, or a related field (Master's a plus). Equivalent professional experience will be considered.
• Relevant certifications are a strong plus, such as cloud credentials (AWS Certified Developer / Solutions Architect) or recognized certifications in your core stack.

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.

Why DFX5

• Build edge technology that matters. You'll create cutting-edge solutions for customers across financial institutions, retail, telcos, CPG, and mining.
• Work with the best. You'll engage with top companies in Latin America and around the world.
• Big challenges, big rewards. You'll tackle genuinely complex problems - and be rewarded for solving them.
