We’re looking for a Senior Engineer who thrives on unfamiliar problems — someone who can land in a customer’s environment, reverse-engineer poorly-documented vendor APIs, and ship a working integration end-to-end, solo.

What makes you a great fit:

• 5+ years of professional software development experience, including 3+ years of hands-on experience in Python.
• Proven track record in designing and building integrations against third-party REST APIs.
• Comfortable working in unfamiliar codebases and picking up new stacks as engagements demand.
• Upper-intermediate written and spoken English.
• Self-managed in an async remote setting — strong ownership, communication, and time management.
• Curiosity and dive-deep mentality — comfortable when documentation is incomplete or absent.

• AI-as-tool fluency — productive use of Claude code, Copilot, Cursor, or similar for research and implementation.

   

Will be a plus:

• Prior customer-facing engineering experience (joining technical calls, gathering requirements).
• Familiarity with security products (SIEM, EDR, vulnerability management, threat intel, firewalls, etc.).

• Experience working in or alongside a SOC.

   

Why work with us?

• People-first management with minimal bureaucracy
• A friendly company culture, proven by employees who choose to return
• Flexible working hours

• Dedicated HR support

   

Your day-to-day in this position:

• Design and build bespoke integrations between our products and customer-specific security stacks — primarily in Python, occasionally in whichever stack the engagement demands.
• Tackle the hardest integration problems: the non-conventional, “out-of-the-books” engagements that standard product connectors can’t cover.
• Own each engagement end-to-end — discovery and technical scoping through implementation, testing, and handover.
• Join customer technical calls alongside PM/CSM to sharpen requirements; drive written follow-up between sessions.
• Reverse-engineer poorly-documented vendor APIs and build robust integrations against them.

• Capture learnings from each engagement and feed them back to the product and integration teams so the next engagement is easier.

   

What is your new project?

• Domain: Computer and network security
• Location: Israel
• Company size: 51-200 employees
• Founded in: 2009
  
  Our next steps:
