Backend Engineer – Founding Team (Tel Aviv)

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.
