What is your new project?

Domain: Data Infrastructure & Analytics / Data Engineering

Client Location: Israel

Company Size: 2–10 employees

Founded in: 2025

A technology startup building an AI-powered platform for autonomous data lakehouse management and optimization. The product automates data maintenance, improves query performance, and reduces infrastructure costs across large-scale data environments using Apache Iceberg. The team focuses on high-performance data systems, distributed computing, Rust-based optimization, and AI integration, offering an opportunity to work on complex data infrastructure challenges in an early-stage product company.

What makes this project exciting?

We're looking for a Data Infrastructure Engineer to build and maintain high-performance data lakehouse infrastructure. You'll develop reliable data maintenance workflows for Apache Iceberg, covering compaction, snapshot expiry, manifest rewriting, and orphan file cleanup, with a strong focus on data integrity and correctness.

This role combines distributed data systems with open-source development. You'll also contribute to a Rust-based, multi-engine SQL query router, maintaining connectors, reviewing community contributions, and shaping the product roadmap. You'll have significant ownership and the opportunity to solve complex data infrastructure challenges in a product-focused startup.

What makes you a great fit

  • 5+ years of software development experience in Java
  • Strong Rust development experience
  • Experience with TypeScript
  • Production experience with data infrastructure and maintaining production systems
  • Working knowledge of Apache Iceberg and Parquet
  • Solid experience with PostgreSQL
  • Experience with Kubernetes
  • Understanding of data maintenance operations and data integrity
  • Ability to work independently and take ownership of technical solutions
  • Strong communication and collaboration skills, including code reviews and open-source contributions

Nice-to-Have:

  • Experience with Apache Spark or DataFusion
  • Experience with query engines such as Trino
  • Experience with SQL routing, query proxying, or multi-engine query systems

Your day-to-day in this position

  • Design and ship the services that turn table health signals into safe, correct maintenance operations
  • Make every commit to a customer’s table verifiably correct, including under concurrent writers, retries, and partial failures
  • Work on a production-grade compaction engine and the systems around it
  • Maintain QueryFlux: triage issues, review pull requests, build new engine connectors, and cut releases
  • Run what you build in production, including on-call and debugging in customers’ real environments

Why work with us?

  • People-first management with minimal bureaucracy
  • A friendly company culture, proven by employees who choose to return
  • Flexible working hours
  • 29 days of PTO (18 working days per year pluse all national holidays)
  • 10 paid recovery days
  • Full financial and legal support for independent contractors
  • Free English classes, with native speakers or Ukrainian teachers
  • Dedicated HR support

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
