Overview

Remo First is unlocking global hiring so companies can build exceptional teams from anywhere.

Our mission is to become the most affordable and accessible global HR platform for more than 400 million businesses. We handle hiring, onboarding, payroll, compliance, and talent management across borders so companies can focus on building, not bureaucracy.

We are scaling at incredible speed and transforming one of the fastest-growing industries in the world.

This is a hands-on role with strong technical ownership and exposure to global-scale systems. This role goes beyond simply implementing requirements - you’d be a real product engineer taking extreme ownership over the quality of your product, caring deeply about our customers and what’s being built. You will collaborate with international engineering, product, and design teams in a fully remote setup.

• 5+ years of backend software development experience
• Strong professional experience with Python (Django, FastAPI, Flask, or similar frameworks)
• Strong professional experience with Java, preferably using Spring Boot.
• Solid understanding of object-oriented design, SOLID principles, and design patterns
• Experience designing and consuming RESTful APIs
• Experience with relational databases (Postgre
  
  SQL, MySQL); exposure to No
  
  SQL databases is a plus
• Familiarity with unit testing, integration testing, and test-driven development (TDD)
• Experience with CI/CD pipelines, Git, and modern development workflows
• Understanding of microservices architecture and distributed systems
• Experience working with cloud platforms (AWS preferred)
• Strong problem-solving skills and attention to performance and scalability
• Excellent written and verbal communication skills in English

• Fully remote role
• Opportunity to work on global-scale systems and products
• Exposure to international teams and modern engineering practices
• High ownership and autonomy in a fast-growing startup environment
• A strong culture grounded in speed, ownership, trust, transparency, customer obsession, and excellence
• Real problems, global impact, and the chance to help redefine how the world works

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
