AES - DE - FED - React

Role Overview
JOB DESCRIPTION
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.
Responsibilities
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
Qualifications
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.

Expectation
What It Looks Like In Practice
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
