Required Senior Software Engineer, Billing
Israel - Tel Aviv
About the role:
"Billing" isn't just about invoices, its the financial heartbeat of a platform protecting over $500B in annual commerce. As we scale toward our next phase of growth, we are looking for a Senior Engineer to architect the mission critical systems that translate massive data streams into financial reality.
We aren't looking for a "maintainer." We are looking for a builder who wants to own the core engine that powers our diverse and expanding product lines.
Why you should join us:
Scale that Matters: Youll handle high-volume data across 1 billion+ identities. This is a "zero-error-margin" environment where precision meets massive scale.
AI-First Development: You wont just use AI tools; youll build them. You will drive continuous efforts to automate complex processes and maintain a custom AI Agent designed to orchestrate billing data and handle automated requests, ensuring our systems remain as fast as they are precise.
High Autonomy, High Impact: The Billing domain is the cornerstone of every new product launch. If you build it, the whole company feels the impact immediately.
What you'll be doing:
Design, build, and maintain scalable and resilient systems that handle high-volume data, while collaborating with teammates and individual contributors
Lead projects from concept to production, ensuring the highest standards of quality and financial integrity.
Work on data-driven initiatives that improve system performance, efficiency, and billing accuracy
Partner with Product and Business stakeholders to navigate technical trade-offs that directly affect our bottom line.
Use AI coding tools as a natural part of how you work, reviewing, guiding, and improving AI-generated code is part of the day-to-day here
Help foster best practices and maintain a high standard of engineering excellence.

We are looking for a Senior Platform Engineer to join our engineering team. This is a hybrid role sitting at the intersection of backend software development and infrastructure engineering. You will own the design and delivery of platform capabilities - from backend services and APIs to the internal developer tooling, CI/CD systems, and Kubernetes-based infrastructure that power our engineering organization.

You will partner closely with software engineering teams, acting as both a builder and an enabler: shipping production-quality backend services while also raising the bar for developer experience, deployment reliability, and infrastructure scalability.

What You'll Be Doing

Design, build, and maintain production-grade backend services, APIs, and microservices.
Develop background workers, event-driven systems, and async processing pipelines.
Define and enforce backend architecture patterns - API design standards, service boundaries, data modeling, and error handling.
Collaborate with product and feature teams to deliver shared platform services (auth, notifications, integrations, etc.).
Integrate and operate AI agents within engineering workflows, using them as active development tools to accelerate delivery and improve code quality.
Contribute to the design and development of corporate AI-agent tooling - building the infrastructure, APIs, and platform abstractions that power our internal LLM-based tools.
Work closely with large language models (LLMs) - including prompt engineering, API integration, and building reliable pipelines around model inference.
Own and evolve our Kubernetes infrastructure, including Helm chart management, workload configuration, RBAC, and cluster operations.
Design and manage CI/CD pipeline templates shared across engineering teams - covering build, test, security scanning, and deployment stages.
Develop internal developer platform tooling that improves self-service capabilities and deployment velocity.
Drive observability best practices using tools like Datadog, OpenTelemetry, and Prometheus.
