We’re hiring a ML Engineer to accelerate AI-driven innovation across Stampli’s B2B SaaS platform.

You’ll be at the forefront of building intelligent systems that power core product experiences and automate internal operations, driving efficiency, speed, and scale across the organization. This is a high-impact, hands-on role in a fast-growing, AI-first company where machine learning is a foundational pillar, not a bolt-on feature. You'll partner with product, engineering, and operations teams to design and implement powerful ML and LLM-based solutions that make a measurable difference.

What You Will Do

• Build Intelligent Systems: Design and develop ML/LLM-powered solutions that solve real-world challenges across Stampli’s product and internal workflows.
• Own Full Lifecycles: Take projects from concept all the way to production, including model training, evaluation, integration, and monitoring.
• Leverage State-of-the-Art Tools: Work with leading frameworks like LangChain, Hugging Face, TensorFlow, and PyTorch to deliver cutting-edge functionality.
• Collaborate Cross-Functionally: Partner with product managers, engineers, and stakeholders to embed AI capabilities into user-facing features and backend services.
• Ship at Scale: Build and maintain scalable APIs and services, integrating best practices in CI/CD, observability, and cloud infrastructure.
• Report with Impact: Share progress, challenges, and results clearly with technical and executive stakeholders.

What You Will Bring

• 6+ years of experience as a Backend Developer, Data Engineer, or ML Engineer
• Strong proficiency in Python
• Deep expertise in designing scalable, resilient, fault-tolerant and secure backend systems
• Strong experience with distributed systems, microservice patterns, asynchronous processing and event-driven architecture
• Proven ability to design and operate high-throughput APIs in production
• Experience leading technical design reviews and making sound architectural tradeoffs
• Excellent problem-solving skills and ownership mindset
• Strong collaboration and communication abilities

Bonus if you have:

• M.Sc. in Computer Science, Software Engineering, or similar field
• Deep experience with LLMs and ML frameworks (e.g., LangChain, LangGraph, Hugging Face, TensorFlow, PyTorch)
• Experience building and scaling LLM-powered applications
• Familiarity with AWS and DevOps best practices (CI/CD, monitoring, IaC)
• Exposure to NoSQL and real-time data processing pipelines

You Will Get

• AI-driven workplace: Work with cutting-edge tools like ChatGPT Enterprise to enhance productivity, spark innovation, and streamline your day-to-day.
• Hybrid model: Join us in our Tel Aviv office three days a week (Tue–Thu), with the flexibility to work remotely the rest of the week.
• Stock options and real ownership in what you help build.
• Career growth supported by experienced, innovation-focused leadership.
• Modern, inclusive environment within a fast-moving scale-up culture.
