Above Security — Tel Aviv (5 days in office)
Above is building the AI-native insider risk platform for the modern enterprise — where humans and AI agents operate together inside security-critical systems.
We're backed by tier-1 global VCs, led by second-time founders, and already deployed with organizations operating at serious scale. AI is not a feature here — it's the system.
We're hiring a Senior AI Engineer to design, fine-tune, and operate AI agents and large-scale models in production. This role exists because off-the-shelf models aren't enough for the problems we're solving.
If you enjoy pushing models until they break — and then fixing them — keep reading.
- Design and operate AI agents that reason, act, and collaborate with humans
- Fine-tune and adapt large language models for:
- Behavior analysis
- Reasoning over long, messy timelines
- High-precision enterprise workflows
- Build agent orchestration systems (tool use, memory, planning, feedback loops)
- Run large-scale inference and training pipelines in production
- Work on model evaluation, drift detection, and continuous improvement
- Optimize for latency, cost, and reliability at real enterprise scale
- Partner closely with DevOps, security, and backend engineers — no research silos
- Ship models that are auditable, explainable, and safe in sensitive environments
- 5+ years in ML / AI / Applied Research roles
- Hands-on experience fine-tuning large models (LLMs or multimodal)
- Deep familiarity with agent architectures (tool use, memory, planning, reflection)
- Real production experience
- Heavy, daily usage of AI coding tools (Claude, Codex, Cursor, etc. — this is how we work)
- Experience operating models at scale (high throughput, real traffic)
- Comfortable working 5 days a week from our Tel Aviv office
- You've shipped agent systems that run unattended in production
- You've fine-tuned models for precision, not just demos
- You think about evaluation frameworks as much as training
- You care about failure modes, hallucinations, and abuse cases
- You prefer impact over papers
- Experience with RLHF / RLAIF / preference optimization
- Background in security, fraud, or behavioral systems
- Experience with multi-agent systems or long-running agents
- Prior startup experience where scale arrived faster than expected
- You'll work on real agent systems, not wrappers around APIs
- Problems are messy, adversarial, and high-stakes — perfect for AI
- Tier-1 funding, serious customers, real scale
- Second-time founders who ship
- Office-first culture focused on velocity and ownership
