The engineering team at Chainalysis is inspired by solving the hardest technical challenges and building products that establish trust in cryptocurrencies. We're a global organization that thrives on challenging work and doing it alongside exceptionally talented teammates. Our industry evolves rapidly, and our mission is to build a flexible, AI-driven platform that automates entity resolution, optimizes data labeling pipelines, and creates predictive models that identify illicit patterns before they escalate.

Our data and solutions have been used to solve some of the world's most high-profile criminal cases and grow consumer access to cryptocurrency safely. Now, by pairing the industry's most trusted blockchain data with agents that reason, investigate, and act, we help our customers scale their workflows as the cryptocurrency economy becomes increasingly mainstream.

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.

• Build & Scale Data Pipelines: Own the architecture of our ETLs and data layers. You’ll be responsible for making systems run 100x faster and handling massive data volumes with precision.

• Lead Technical Excellence: Once in the Lead role, you will mentor a team of senior engineers, driving code quality, performance-critical flows, and architectural standards.

• Drive the Roadmap: Partner with Product Managers to translate complex fraud-prevention requirements into robust, production-grade technical solutions.

AI at Chainalysis
AI is not a feature at Chainalysis - it is a new way of working. One that turns instructions into work done, and helps us move faster than the threats we're built to counter, and we expect our employees to take ownership of the output and ensure quality. As the world's most trusted blockchain analytics platform, Chainalysis sits at a rare intersection of proprietary data, regulatory relationships and crypto expertise that makes it uniquely placed to shape and lead the next era of AI-driven intelligence - and we expect everyone here, regardless of role, to be an active part of it.

AI fluency is tied directly to how we measure performance and how we plan to win. There is no substitute for your own curiosity. We provide the tools, workflows, and space to experiment - but the expectation is that you develop these capabilities yourself, bring ideas, and collaborate across teams to reinvent the way work gets done. We are not using AI to do less. We are using it to do what was never possible before.
