Senior Backend Engineer

I’m looking for a senior full stack developer who can move fast, code fast, and lead projects from concept to delivery using Claude Code as a development accelerator.

You should be comfortable taking ownership of full features and delivering complete, production-ready results quickly. The right person knows how to leverage Claude Code for rapid iteration, build structured systems fast, and manage a small remote team of developers to keep progress constant.

We are building automation and trade software tools that require strong backend architecture, asynchronous task processing, and modern, responsive interfaces. You’ll be directly responsible for shaping and delivering new systems end-to-end.

Your work will include:

• Leading development of new modules and full products  

• Building backend logic in Django with Celery task flows  

• Developing frontends with Angular or React  

• Using Claude Code daily to accelerate development and testing  

• Managing tasks, coordinating developers, and ensuring constant delivery  

• Integrating APIs, handling data processing, and optimizing performance

You must be a hands-on coder who thrives in a fast execution environment and can manage both code quality and delivery speed.

Requirements:

• Strong experience with Django, Celery, and REST APIs  

• Solid frontend experience with Angular or React  

• Excellent understanding of asynchronous systems and data pipelines  

• Proven experience leading developers or managing sprints  

• Experience with PostgreSQL, Docker, and Git based workflows  

• Familiarity with financial or trade software is a big plus  

• Strong communication skills and ability to manage progress across multiple projects  

• Comfortable using Claude Code or similar AI coding tools to build fast

I’m looking for a senior professional who can code, lead, and deliver without delay. Someone who can think strategically, execute quickly, and ensure results every week.

This is a full-time role for someone who wants to lead high-speed development and deliver complete, real-world systems with the help of AI coding tools.
