Job Description

We’re specifically looking for a Principal Software Developer (Ruby on Rails & React) - Freelancer

What We’re Looking For

• 8+ years of experience in software development, with deep, senior-level expertise in Ruby on Rails and React
• A proven senior profile, someone who doesn’t just execute, but defines direction, shapes systems, and confidently makes architectural and product decisions
• Strong sense of end-to-end ownership: you are comfortable setting the roadmap, identifying gaps, and continuously building on top of existing systems without needing close guidance
• A senior-level commitment to quality, with extensive experience designing and maintaining robust test suites; testing is a core part of how you build, not an afterthought
• Clear and demonstrated focus on admin panels and internal tooling, with the maturity to design for usability, maintainability, and long-term evolution (not user-facing products)
• Experience working closely with internal stakeholders, with the communication skills and seniority to translate needs into well-structured solutions across varying levels of complexity
• Background in smaller-scale environments (e.g., internal tools, limited user bases), where pragmatic decision-making and thoughtful trade-offs are more important than hyper-scale concerns
• A self-directed, senior mindset, you bring structure to ambiguity, operate independently, and take responsibility for both the technical direction and its outcomes
