Backend Software Engineer

Summary

Join our team as a Backend Engineer and build cutting-edge backend services from the ground up. This 6-month contract role (with potential for extension) offers the chance to make a significant impact on greenfield projects within our fintech client's brokerage or crypto teams. You will design RESTful APIs, solve complex engineering problems, and collaborate with a team that values speed and technical excellence.

The ideal candidate possesses a proven track record of building greenfield systems and proficiency in Golang or Python.

Responsibilities

• Build backend services from scratch — from architecture to deployment
• Design RESTful APIs and highly concurrent systems that handle real‑world 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
