About the job

Reclaim Security is on a mission to shake things up in cybersecurity, and we’re looking for a highly experienced Backend Engineer who lives and breathes technology and data to join our founding team in Tel Aviv.

What You'll Do:

You’ll be designing and building a groundbreaking product from scratch.

That means:

Owning major parts of the backend and design scalable architectures.
Develop a reliable, testable production-grade code.
Integrating with complex customer environments and 3rd parties tools.
Organise the ever-growing data streams, making them behave, and keeping things running smoothly.
Finding creative ways to solve really hard problems.
Navigating the beautiful chaos of an early-stage startup—turning uncertainty into innovation.

Who We Are:

Reclaim Security is built by seasoned security experts with a track record of making an impact. We’re tackling an uncharted problem in cybersecurity that companies have been struggling with for way too long.

Our team? A group of friends who love what they do.

We appreciate a good humor, strong opinions (backed by facts), and the radical idea that people should actually feel empowered to do their jobs.

Who You Are:

You’ve got 7+ years of experience building complex software systems in Go, Rust, Python, Java, or Scala.
You know your way around cloud-native platforms (AWS, GCP, Azure) and have Kubernetes battle scars.
You thrive in startups—you love bringing ideas to life, navigating ambiguity, and turning chaos into structure.
You actually care about writing A+ grade code but know that sometimes you just need to make things work.
You’re a team player who takes ownership and genuinely enjoys building great software.

Bonus Points If You:

Have experience with data processing frameworks like Apache Spark and Polars.
Have worked with APIs, data serialization tools (Avro, Protobuf), and designed data architectures.
Have a strong data engineering background.

Why You Should Join Us:

Build something from zero to one—this is a rare opportunity to be at the foundation of something big.
No corporate nonsense—we move fast, make decisions quickly, and actually ship things.
Passionate team—we take our work seriously, but we don’t take ourselves too seriously.
Your impact will be real—this isn’t a “fix tickets all day” kind of job. You’ll help shape the future of cybersecurity.
