Senior Fullstack Engineer
Finout
Senior Full-Stack Engineer
Cloud is now one of the biggest business expenses and one of the hardest to manage. At Finout, we're not just shedding light on spend—we're giving companies the power to make smarter, faster, and more strategic decisions about the cloud. We're trusted by brands like The New York Times, Wiz, Elastic, SiriusXM, and Lyft, and backed by top-tier investors with over $85M raised. In just 4 years, we've grown to 100+ people across Tel Aviv and New York—and we're just getting started. If you're looking to build something big, solve real problems, and grow fast -we'd love to meet you.
About the Role
As a Senior Full-Stack Engineer at Finout, you'll be at the forefront of building and scaling our product from the ground up. You'll work closely with your team, as well as a product and product designer, to design and implement both the front-end user experience and back-end logic that powers our platform.
You'll play a key role in creating modern UI components, building API services, and contributing to core architectural decisions in a high-impact, low-ego team environment.
What You'll Do:
- Design and implement scalable Senior Full Stack Engineer features and components using NodeJS and React
- Build and maintain robust APIs and data pipelines to support the platform
- Collaborate closely with product, design, and engineering leadership on architecture and UX
- Participate in code reviews, testing, CI/CD, and overall platform improvements
- Bring creativity, curiosity, and best practices to everything you build
What We're Looking For:
- 5+ years of experience in software engineering.
- Proficiency in NodeJS and React (or deep JavaScript expertise)
- Strong understanding of both frontend and backend systems
- Autodidact and self-driven with a problem-solving mindset
- Excellent communication and collaboration skills
- Comfortable in a fast-paced, startup environment
- Academic degree in Computer Science (or similar)
- Familiarity with CI/CD pipelines and modern DevOps practices is a plus
Our Values
We're a hybrid company with a big vision and a startup soul. If you're excited to help shape the future of cloud infrastructure and join a team that cares deeply about what (and how) we build—we'd love to meet you.
