Were hiring a Senior Full Stack Engineer to help evolve our AI-first AP Automation platform.

Youll be a key player in building a unified system that gives companies full control and visibility over spending, from invoices to AP credit cards to payments.

This is a high-impact role in a fast-growing startup where AI is not just a feature but a foundation.

Youll architect and deliver scalable, intuitive web experiences that drive efficiency, transparency, and collaboration across the finance workflow.

What You Will Do
End-to-End Development: Build and enhance our platform using Java and React, delivering seamless, performant user experiences across web applications.
AI-Enhanced Feature Delivery: Work closely with AI and product teams to integrate smart automations, faster approval workflows, and contextual user assistance throughout the application- MUST.
Performance Optimization: Ensure responsiveness and scalability of the application, handling large data sets and user volumes efficiently.
Collaborative Problem Solving: Partner with designers, PMs, and fellow engineers to transform business needs into elegant technical solutions.
Clean Code & Best Practices: Write robust, maintainable, and testable code. Participate in code reviews and contribute to engineering excellence.
Continuous Improvement: Keep up with new trends and technologies-especially in AI/ML-and look for opportunities to evolve our systems and architecture.

We are a global investment platform connecting accredited investors and institutions with vetted, early-stage startups and venture funds. Behind that platform sits a tech organization building the systems that power how thousands of investors discover, evaluate, and act on private-market opportunities. We're now expanding our Technology team with engineers who can build the next generation of AI-driven products at the core of our platform.
 
Why Join Us? This is a chance to build at the intersection of fintech and applied AI, not as a side experiment, but as the direction of the product. You'll design and ship production-grade backend and FullStack systems that sit at the heart of a real, global investment platform, while being hands-on building AI agents that teams across the company actually depend on: architecting scalable microservices in Node.js, putting LLMs and agentic tooling to work, and owning features end to end from design through deployment.
Because real users and real capital flow through our platform, your work ships and matters from day one. You'll get real ownership over the features you build, hands-on exposure to how we adopt agentic AI, and a front-row seat to the startup and innovation ecosystem we live inside every day. If you want to master cutting-edge AI tooling while solving hard distributed systems problems alongside a small, sharp team - this is the place to do it.
This role requires 3 days a week in-office with the technology team primarily based out of Tel Aviv. Since we are headquartered in Jerusalem, candidates based in and around Jerusalem are welcome to apply, provided they're comfortable with Tel Aviv as the team's main hub.
Responsibilities:
 
* Design, build, and ship production backend and FullStack features for our investment platform using Node.js and microservices
* Build and deploy AI agents and LLM-powered tools used in production across the company, from prototype to rollout
* Architect and maintain scalable microservices, integrating SQL and NoSQL data stores as needed
* Design agentic workflows and orchestration pipelines, using low-code tools (e.g. n8n, Make) alongside custom services where appropriate
* Own features end to end: design, estimation, implementation, testing, deployment, and monitoring
* Partner with product, data, and engineering teams to turn business and investor needs into technical solutions
* Evaluate emerging LLM frameworks and AI tooling to keep our stack current and production-ready
* Write clean, well-tested code and participate in code reviews to uphold team quality standards
* Troubleshoot issues across the stack, balancing delivery speed with the reliability a capital platform demands
* Help shape architecture, tooling, and best practices as the team scales its use of agentic AI

Interview Process:
* Recruiter phone call
* Take home assignment
* In-person interview with Manager
* In-person interview with Department Head
* In-person interview with HR
* References
