What Do We Do?

Triple Whale is the AI operating system built for modern commmerce. We help you see what's actually working in your business, what's not, and what to do next. Then we take action for you — pausing the underperforming ad, generating the next batch of creative, flagging the inventory risk before it hurts your bottom line.
We pull every signal in your business into one place, and put it on the most trusted measurement foundation in the industry. And on top of that, we give you the only AI harness in commerce — Moby — letting you tap any LLM you want, grounded in the full context of your business. Moby doesn't just surface insights, it executes decisions for you, with automations that make the rest of your stack smarter.
The result: more than 65,000 brands like Kitsch, OUAI, and True Classic turn mountains of complex data into actions that actually grow profit, at a speed and scale that is not humanly possible.

Why Triple Whale Needs You:

Triple Whale is a data and AI platform serving thousands of ecommerce brands. We handle sensitive merchant data and credentials, making security core to our product.

Are you passionate about building reliable, scalable systems? Do you thrive on open-ended problems? Do you love designing, building, and owning complex infrastructure from conception to production?  If yes, you’re in the right place.

A big focus on this position will be building security controls across our cloud infrastructure, applications, and AI systems. You’ll work alongside the Infrastructure and engineering teams to turn security requirements into practical protections that support fast development.

What You’ll Do:

• Run our GKE clusters - scaling, node pools, capacity planning and peak readiness.
• Operate stateful systems at scale.
• Build internal tooling that accelerates developer velocity.
• Help other teams and developers design robust and scalable and secure systems.
• Run observability, monitoring and incident response: alerts that mean something, fast root-cause analysis and postmortems that turn into code.
• Do security engineering in any part of the system and the development process.

What You’ll Bring:

• Ability to work from our Jerusalem office twice a week (Mondays and Wednesdays), conveniently located at the Central Bus Station, next to the train station.
• High level of English (spoken and written)
• 6+ years of experience as an independent backend or infrastructure engineer
• Ability to design and build scalable, reliable systems
• Strong communication skills
• Hands-on builder mentality - this is a coding role.
• Good judgment about blast radius: you know when to move fast and when to stage a change, and you can explain the difference.
• Experience with:
• Relational and non-relational databases
• Major Cloud platforms (GCP, AWS, Azure), GCP is an advantage
• Streaming systems
• Scaling large systems
• Message queues
• Monitoring systems like DataDog, Grafana, Groundcover
• CI/CD, Git
• Kubernetes experience: you've debugged scheduling, networking, autoscaling and resource pressure in a real cluster.

• Infrastructure: Kubernetes, Knative, GCP, Temporal, Pulumi
• Languages: Node.js, TypeScript, Python

• We Are Trustworthy: Candor, directness, and honest communication helps us learn, grow and improve so we can win together.
• We Are Curious: We extend beyond our comfort zone and ask questions that guide us towards new, creative, and bold paths.
