Hi there!
We are currently looking for a strong Full-Stack Developer-AI-First SaaS Engineer
About Us:
5Blue Software is an Israeli-Ukrainian software development company specializing in custom software development, staff augmentation, dedicated engineering teams, AI solutions, and CTO-as-a-Service. We help startups and mid-sized companies scale faster with vetted engineering talent across Europe.
About the project:
Join a fast-growing AI-first product company building a B2B SaaS platform that helps organizations simplify security, compliance, and AI governance.
The platform automates processes that traditionally require significant manual work — from evidence collection and monitoring to audit preparation and certification workflows.
You'll join a lean, highly collaborative international engineering team distributed across Europe, Israel, and South Africa.
About the role:
We're looking for a Senior Full-Stack Developer who is comfortable working across both frontend and backend and enjoys taking ownership of features from idea to production.
This is an AI-first engineering environment. AI is used both as part of the product and as a standard part of the development workflow. You'll use AI-assisted development tools to accelerate implementation, debugging, testing, and refactoring while maintaining strong engineering judgment and the ability to write and understand code independently.
You'll work closely with Engineering and Product on system design, architecture, and feature development, with a particular focus on building high-quality React experiences while contributing confidently to the backend.
What you'll do:
-
Build and deliver full-stack features end to end using React, TypeScript, and Node.js.
-
Develop intuitive, performant, and scalable frontend experiences for a complex B2B SaaS product.
-
Implement backend services, APIs, business logic, and third-party integrations.
-
Develop and integrate AI-powered product features.
-
Participate in system design and architectural decisions.
-
Use AI-assisted development tools such as Claude Code or similar as part of your everyday workflow.
-
Review, debug, test, and improve AI-generated code while maintaining ownership of the implementation.
