To thrive as a Contract Backend Developer, you need strong programming skills in languages like Python, Java, or Node.js, along with experience in database management and API development, supported by a relevant degree or proven project experience. Familiarity with frameworks (such as Django, Spring, or Express), cloud services (like AWS or Azure), and version control systems (e.g., Git) is typically expected.

Contract Backend Developers often encounter challenges such as quickly understanding existing codebases, adapting to different tech stacks, and aligning with the team's development practices.

Effective communication with team members and proactive clarification of requirements are essential to ensure smooth integration and successful project outcomes.

What are contract backend developers?

Contract backend developers are professionals hired on a temporary or project basis to build and maintain the server-side logic, databases, and APIs that power web or mobile applications. They work behind the scenes to ensure that applications function smoothly, handle data efficiently, and communicate effectively with front-end systems. Unlike full-time employees, contract backend developers typically work for a set duration or on specific projects, offering flexibility to both clients and developers. They often bring specialized expertise in programming languages such as Python, Java, Node.js, or Ruby, and may work remotely or on-site depending on the contract terms.

Job description

Company Description

This is a contract position for one of our fintech clients. This person will be working within either the brokerage or crypto teams!

Job Description

We're looking for a backend engineer who gets excited about building things that don't exist yet.
This is not a role for someone who only maintains or "tunes" existing systems - we need someone who can take a blank slate and turn it into a productionready service.

You'll be working on greenfield projects with a team that values speed, technical excellence, and ownership. This is a 6month contract role with potential for extension and/or conversion, but in those six months, you'll make a tangible impact.

Important:

  • You must be based in the United States.

  • We can't provide visa sponsorship for this role.

  • This is a contract position, fully remote within the US.

  • This contract would be a W-2 position, we cannot do a 1099 or C2C at this time

Qualifications

What you'll do

  • Build backend services from scratch - from architecture to deployment.

  • Design RESTful APIs and highly concurrent systems that handle realworld scale.

  • Solve complex engineering problems and make sound decisions about priorities.

  • Collaborate closely with other engineers to deliver fast, maintainable code.

  • Contribute to a culture of ownership: review code, share knowledge, and mentor where you can.

What makes someone a great fit

  • 3+ years of experience in backend development.

  • Proven track record of building greenfield systems (not just maintaining legacy code).

  • Proficiency in Golang or Python (both are great).

  • Experience with cloudnative architectures (AWS, Kubernetes, Docker).

  • Strong grasp of REST API design, distributed systems, and concurrency.

Additional Information

All your information will be kept confidential according to EEO guidelines.
