Our culture is built on five core values that inform everything we do. We encourage collaboration, feedback, ownership, and maintain a growth mindset. We know experience comes in many forms - some visible on your resume, others not. No one candidate will be a 100% perfect match to our description, so if you thrive in a fast-paced, intellectually curious environment and have relevant experience, we encourage you to apply.

We're looking for a ML Engineer to join our Data team in Tel Aviv. Our team sits at the heart of HoneyBook's data stack - we build and maintain the infrastructure, pipelines, and AI-powered systems that DS, product, marketing and other stakeholders rely on to move fast and make smart decisions.

What you'll work on:

• Integrate and productionize LLM-based systems: from prompt registries and model gateways to agentic workflows - with a focus on reliability, observability, and cost efficiency.

• Own our core MLOps infrastructure: build and maintain our feature store, vector database, training and monitoring tools, etc.- so DS and product teams can ship AI features without infrastructure becoming the bottleneck.

• Build AI-powered Python microservices that integrate LLMs, scraping, pipelines and internal data into product features used by hundreds of thousands of businesses.

• Collaborate deeply with data scientists, engineers and product managers to turn ideas into reliable, scalable ML systems, iterating quickly from prototype to production.

• Own initiatives end-to-end: from design doc to production deployment, including monitoring, documentation, and handoff.

Here is what is needed:

• 4+ years of production engineering experience, with at least 3 years working on data-intensive systems in Python.

• Mindset of ownership, curiosity, and can-do attitude in a fast‑moving environment.

• Hands-on experience with LLM-based systems in production - prompt management, scale, cost optimization, latency, and reliability.

• Distributed systems fluency - event-driven architecture, idempotency, backpressure, schema evolution.

• Workflow orchestration experience, both batch and streaming.

• Comfortable with ambiguity - scoping unclear requests, making speed vs. robustness tradeoffs, communicating transparently when things change.

• Strong collaboration and communication skills in Hebrew and English

Nice to have:

• Experience with MLOps tooling (feature stores, training pipelines, model serving, or equivalent).

• SQL and data warehouse fluency (DBT, Snowflake, or equivalent).

The good stuff:

Mission-driven: You'll be joining more than just another startup. Our members’ success is at the heart of everything we do.

Impact: We move quickly and encourage every employee to push the envelope. Our best ideas come from out-of-the-box thinking and innovation; be ready to fail fast and often!

Compensation: We offer a competitive salary and meaningful equity grants.

Benefits & perks: From wellness programs to exceptional family leave policies, the health and happiness of our employees are foremost.

Our core values:

People come first: We prioritize people as we explore opportunities and work through challenges.
Raise the bar: We push for greatness—for ourselves, each other, and our members.
Own it: Trust and ownership let us make decisions with confidence.
We love what we do: We bring passion to our work and love what we create for our members.
Keep it real: Authenticity, respect, and transparency are at our core.
