We are looking for a Staff-level Backend Engineer who is ready to transition into an Engineering Team Lead role within 3–6 months for our Alterya team. This team operates as an innovation hub in Tel Aviv at the intersection of AI, fraud prevention, and large-scale data intelligence, where you will eventually be responsible for the growth, delivery, and technical excellence for one if its core squads. As an Engineering Team Lead, you will be a pivotal leader in our mission. You will lead a high-performing team of engineers building and scaling the APIs and data layers that global institutions rely on to stop crime, manage risk, and fight fraud.

In this job, you'll:

• Lead & Mentor: Drive a team of experienced software engineers, providing technical guidance, career coaching, and fostering a culture of high performance and continuous learning.

• Drive the Roadmap: Partner with Product Managers to translate complex fraud-prevention requirements into robust, production-grade technical solutions.
• Optimize Everything: From PostgreSQL queries to Kubernetes-based deployments, you will look for ways to overhaul scalability and efficiency across the stack.

We're looking for candidates who have:

• AI-First Engineering Mindset: You are an "AI-First" developer who leverages AI tools to accelerate development. You understand how to support, build, and deploy tooling that employs AI (LLMs, agents, etc.) throughout the organization and tech stack.
• Seniority with Ambition: 6+ years of backend experience. You've likely led projects or mentored teams and are ready to officially step into a Team Lead role.
• Database Mastery: Strong familiarity with PostgreSQL (performance tuning is a plus), Redis, and BigQuery.
• Solid Communicator: You are a great communicator - highly effective at coordinating with leaders and fellow leads to solve complex problems across teams.
• Startup DNA: You prefer a "get it done" environment. You want to feel the impact of your work and thrive in a high-growth, technical culture.
• High Standards: You take pride in clean, scalable, and testable code.

You might also have:

• Experience in Fintech, Cyber-security, or Fraud detection domains.
