Description
Experience Level: Expert
Project Description:
We are a startup looking for a Backend Engineer to join our team and help build our product.
This role is not for someone who is only looking for small freelance tasks. We need a serious backend engineer who can work with the responsibility, communication, and technical discipline expected from a full-time team member.
You will be involved in backend architecture, API development, database design, integrations, debugging, performance improvements, and product-related technical decisions. You should be able to understand business requirements, communicate clearly with customers, and deliver clean, reliable, production-ready backend work.
Key Responsibilities:
- Build and maintain backend APIs and services
- Design and manage database structures
- Implement authentication, authorization, and business logic
- Integrate third-party APIs and services
- Debug complex issues and solve root causes
- Communicate professionally with customers and team members
- Translate product and customer requirements into technical solutions
- Maintain high standards for code quality, security, and reliability
Required Qualities:
- Strong backend engineering experience
- Production-level coding ability
- Excellent communication skills
- Ability to speak with customers in a professional and clear way
- Ownership mindset
- Reliability and accountability
- Startup mentality: practical, fast-moving, and problem-solving focused
- Full-time employee-level working standard, even if the contract starts as remote or freelance
Technical Skills:
- Backend framework experience such as Node.js, NestJS, Express, Python, Django, FastAPI, or similar
- Strong database experience with PostgreSQL, MySQL, MongoDB, Supabase, or similar
- REST API design
- Authentication and permission systems
- Git and professional development workflow
- Security and performance awareness
Nice to Have:
- SaaS product experience
- Cloud experience with AWS, GCP, or similar
- Docker or deployment experience
- Stripe/payment integration experience
- Experience working directly with startup founders or customers
To apply, please send:
- Your backend development background
- Relevant production project examples
- Your strongest backend stack
- Your availability
- Your rate or salary expectation
