About the Role
FRACTIONAL SENIOR FULL STACK ENGINEER (STABILIZATION / AI-GENERATED CODE)
Location: Remote (LATAM & Eastern Europe)
Type: Contract / Fractional (10–40 hrs/week)
OVERVIEW
We’re hiring a senior, hands-on engineer to support multiple early-stage products that need stabilization.
Most projects were built quickly by non-technical founders using AI tools. As a result, codebases are often incomplete, inconsistent, or fragile.
This role is focused on reviewing, fixing, and stabilizing existing systems not just building new features.
WHAT YOU’LL DO
- Review and assess existing codebases (often AI-generated or founder-built)
- Identify bugs, structural issues, and technical risks
- Refactor and stabilize applications for production use
- Improve performance, structure, and maintainability
- Fill gaps in core functionality (auth, payments, backend logic)
- Implement lightweight QA / testing where needed
- Collaborate with engineers, QA, and project leads
- Work across multiple projects as priorities shift
WHAT WE’RE LOOKING FOR
- 5+ years of full stack experience
- Strong experience working in messy / inherited codebases
- Comfortable operating without full documentation
- Proven ability to take products from MVP → stable product
- Practical, solution-oriented mindset (not theoretical)
- Strong communication and team collaboration
- Comfortable in fast-moving, delivery-focused environments
TECH STACK (FLEXIBLE)
- Python (FastAPI, Django) - preferred
- Node.js / TypeScript
- React / Next.js
- Firebase, Supabase, or similar
- APIs & modern web architectures
Flexibility > specialization
ENGAGEMENT MODEL
- Fractional, hourly
- 10–40 hrs/week depending on project load
- Initial engagements ~4 weeks
- Ongoing work across multiple client projects
