Right now, someone in your company is pasting something they shouldn't into an AI tool.

A contract into a chatbot. A customer list into an assistant that got installed last week. Source code into a model nobody approved.

It's happening in every organization on earth, thousands of times a day. Seeing it after the fact is hard enough.

Stopping it in the moment, without getting in anyone's way- that's the actual engineering problem.

ORION is a data security startup in Tel Aviv. $38M raised, and Fortune 500 enterprises already running us in production, betting their most sensitive data on us being right.
We're looking for a Senior Software Engineer to own real parts of it.

What you'll actually do?

• Own entire pieces of the product- from "here's a vague problem" to "it's running for enterprise customers".
• Design systems that survive real scale: multi-tenant, high-volume, real-time, always-on.
• Move fast with AI agents, and stay completely responsible for what lands in production.
• Make the team better: your tooling, your workflows, whatever you figured out last weekend.

Who you are?

You've been doing this 5+ years and you have the production scars to prove it.

You think in systems, not tickets. You use AI agents every day and you have opinions about how - planning, context, when to let them run and when to shut them down.

You've owned something big and complex end to end, and you'd rather do that again than be handed a backlog.

Formally:

• 5+ years hands-on backend / full-stack- MUST
• Strong system design fundamentals: data modeling, scale, resilience, trade-offs- MUST
• Versatility across the stack, with real experience owning services in production on cloud infrastructure- MUST
• Daily, practical use of AI coding agents beyond prompting: context management, planning, skills/commands, MCP- MUST
• Proven end-to-end ownership of complex projects- MUST
• Experience in Cybersecurity, data security, or data-heavy platforms- Advantage
• Built AI-native features in production: LLM pipelines, agents, evals- Advantage

Why ORION?

• $38M raised, Fortune 500 customers, a category growing faster than we can hire for.
• Senior here means senior- you lead initiatives, you don't get assigned tickets.
• An engineering org that's genuinely AI-native, not AI-flavored.
• Small teams, short distance from idea to production.
