Job description
Experience required
At least 8+ years hands on in full stack development
Role Summary
- We are looking for experienced full stack contractors to build production-grade web applications and APIs. You will own features end to end from database schema through backend services to the user interface.
- This is a hands-on build role for engineers who are comfortable working through ambiguity, shaping the design as much as writing the code, and operating as an owner rather than a ticket-taker.
Must-Have Skills
Frontend
- Strong JavaScript fundamentals (ES6+, async/await, closures)
- React experience preferred (hooks, state management, component architecture)
Backend
- Proficient in Python, writing production-grade code
- Hands-on experience with FastAPI or Flask for building REST APIs
Database
- Experience with relational databases (PostgreSQL, MySQL, SQL Server, or equivalent)
- Good understanding of schema design, joins, indexing, and query optimization
Architecture & Problem Solving
- Ability to think through system design and build scalable solutions
- Strong analytical mindset to break down complex or ambiguous problems
Good-to-Have Skills
- Experience with Claude Code or other AI-assisted development tools extra points for this
- desktop app based on Electron framework - Extra points for this
- Agentic Frameworks (ADK, Langraph )
- API documentation (Swagger / OpenAPI)
- Git and version control best practices
- Basic DevOps awareness (Docker, CI/CD)
- Testing experience, both unit and integration
Behavioral Expectations (Non-Negotiable)
These are weighted equally with technical skill. Candidates who are strong engineers but weak here will not be a fit.
- Proactive communication – Shares updates without being asked and flags blockers early
- Asks the right questions – Clarifies requirements upfront before jumping into implementation
- No working in silos – Collaborates openly, seeks feedback, and loops in stakeholders regularly
- Ownership mindset – Treats the project as their own rather than just completing tickets
- Transparency – Speaks up when something is unclear instead of making assumptions
What Success Looks Like
- Features shipped end to end schema, API, and UI with minimal hand-holding
- Requirements clarified early, so rework is rare
- Blockers surfaced the day they appear, not at the end of the sprint
- Code that others can read, test, and extend
