Full-Stack Developer (Next.JS) at DYO Investments
Job Description
You’ll be most successful if you can connect the dots between UI behavior, API contracts, and the data-processing logic behind the results. We’re not only looking for someone who can “make changes”—we’re looking for someone who can reason about the whole system and improve it.
- Strong Next.js experience (components, routing, performance considerations, and debugging).
- Backend experience with FastAPI (API design, dependency patterns, validation, and handling edge cases).
- Data-processing proficiency with Pandas and NumPy, including understanding performance implications and correctness.
- Comfort with the full stack: you can explain how a change in the frontend affects API behavior and downstream data processing.
- AWS and Vercel familiarity for deployment workflows, configuration, and operational troubleshooting.
- Practical debugging skills across environments (local vs. staging/production).
Soft skills we value:
- Ownership and a proactive mindset when requirements are not fully specified.
- Clear communication - we want you to be comfortable explaining the nature of issues to non-technical team members and fielding feedback from the team.
- Attention to detail for data correctness and reliability, especially in a data science-oriented application.
- Team collaboration to iterate quickly while keeping the codebase maintainable.
If you enjoy working at the intersection of web engineering and data-heavy computation, and you understand that reliability matters as much as new features, we’d like to talk.
