Backend Engineer

Location: Tel-Aviv (IL)

Description

As a Senior Full Stack Engineer on our Credit/Terms team, you'll play a key role in building the systems that power our infrastructure. While the role is primarily backend-focused, you'll have the opportunity to contribute across the stack, influence technical direction, and take ownership of initiatives that align with your expertise and interests.

We're looking for engineers who enjoy solving complex technical challenges and are excited to expand their impact beyond feature development. Whether it's architecture, infrastructure, AI-powered capabilities, developer experience, performance optimization, or mentoring other engineers, you'll have the freedom to shape your technical journey while helping build a scalable, reliable platform.

Responsibilities

• Own the full software development lifecycle, from architecture and design to deployment and monitoring, with a primary focus on backend systems.
• Design, build, and maintain scalable, high-performance RESTful APIs for internal and external integrations.
• Develop reliable, low-latency payment services that support a growing production environment.
• Collaborate closely with Product,Risk, Design, and Engineering teams to deliver impactful features in an Agile environment.
• Drive architectural discussions and influence technical decisions across the team.
• Identify, troubleshoot, and resolve production issues while continuously improving system performance and reliability.
• Mentor fellow engineers through technical guidance, code reviews, and knowledge sharing.
• Take ownership of technical initiatives beyond your day-to-day responsibilities, such as infrastructure improvements, developer tooling, AI adoption, platform enhancements, security, or other engineering challenges that move the organization forward.
• Continuously evaluate new technologies and best practices to improve engineering quality, scalability, and developer productivity.

Requirements

• 5+ years of experience in server-side development (Node.js is strongly preferred).
• Experience with frontend development using React or a similar framework.
• Strong understanding of distributed systems and microservices architecture.
• Experience working with production-scale databases such as PostgreSQL and MongoDB, including optimization and performance tuning.
• Hands-on experience with AWS cloud services, including Serverless, Kubernetes, and Docker.
• Solid understanding of RESTful API design and modern service-oriented architectures.
• Experience with CI/CD pipelines and Agile development practices.
• Strong problem-solving skills and the ability to work independently while collaborating effectively across teams.
• Excellent communication skills and the ability to translate technical concepts into practical solutions.
• Curiosity and a desire to take ownership of technical challenges beyond your core responsibilities.
