Twine Security · Israel

Twine builds AI Digital Employees who help cyber teams close the execution gap. Our first AI Digital Employee, Alex, learns, understands and takes away the burden of Identity and Access Management (IAM) tasks - proactively completing the organization's cyber objectives. About the role: You'll design, build, and ship the AI systems behind Alex: production agents that reason over customer identity data, call real tools, and complete IAM tasks end to end. Starting from a cybersecurity need, you'll frame the technical problem, choose an approach, and own the solution through production: architecture, implementation, evaluation, deployment, and iteration on real customer behavior. You'll build on Twine's shared agent infrastructure and extend it: new tools and integrations, workflow orchestration, context and memory management, evaluation harnesses, and the guardrails that keep an autonomous agent safe inside a customer's environment. This is a hands-on engineering role, not a research position. The goal is not to prove that an idea can work; it is to make it useful, reliable, and observable for customers in production. Responsibilities Design, implement, and ship AI-powered features for complex cybersecurity workflows, from prototype to production. Build the systems that make agents work in practice: tool integrations, planning and orchestration logic, context management, structured outputs, and recovery from failures. Choose the right technical approach for each problem, combining models, deterministic logic, data, and conventional software where appropriate. Define quality for each use case and build the evaluation pipelines that measure correctness, task completion, consistency, safety, latency, and cost, and wire them into CI and release. Debug agent behavior in production: trace failures to their root cause in the prompt, tool, data, or architecture, and fix it. Own the reliability, observability, and cost of the agent systems you build. Collaborate with cybersecurity experts, product, and platform engineers throughout development. Requirements Excellent software engineering skills and substantial production experience with Python. Experience shipping and operating backend systems in production: APIs, async processing, data pipelines, testing, and observability. Hands-on experience building applications on modern language models: tool use, structured generation, retrieval, prompt and context management, and evaluation. Sound judgment about when to use an AI technique and when a deterministic approach is more effective. Comfort owning a problem end to end, from an ambiguous requirement to a system running reliably in production. Nice to have Building autonomous or long-running agents that interact with real systems. Building evaluation pipelines, simulations, or benchmarks for model behavior. Experience in cybersecurity, identity, security operations, or enterprise automation. Experience with agent frameworks, MCP, or LLM observability and tracing tools. Intertwine your future with ours Applying for AI Engineer. Send us your details and CV - we read every one.

Then translate those insights into signals that can be used for detection and analysis of a model response. The field of LLM interpretability at scale is exploding, with several major publications in the last months, and major opportunities for innovation. What You’ll Do Responsibilities: • Investigate model internals, including activation/features analysis, unsupervised clustering, discovery of directions in latent space, etc. It may also require training specific model parts to improve interpretability metrics. • Design security‑grounded evaluations: curate datasets for different attack types, evaluate performance of different white box (model internals) methods compared to black box (input/output only) baselines. • Publish and share: produce Zenity Labs posts and open artifacts; when the work is strong, aim for tier‑1 ML venues (NeurIPS, ICML, etc.) and security forums. A publication of code and/or trained models in cases of community relevant novelty. • Build tools: Several open source libraries exist (like Anthropic’s attribution graphs infra), but the research in the field is very dynamic, which will require you to build and adapt tools to your own research directions. This also includes agents to automate research work and distill knowledge from designed experiments. Requirements Requirements: • Deep learning expertise with a track record of non‑trivial research (industry or academia) in LLMs or other domains (e.g., CV, speech). We care that you’ve changed models or methods in meaningful ways (architecture/training/eval), not just used them. • Strong experimental design and scientific writing; comfort pre‑registering hypotheses, testing causal claims, proposing novel directions in a fast-changing field. • PhD or equivalent research experience in the industry (5+ years in a leading research team). Publication record or a portfolio of high‑impact open artifacts will make you stand out from the crowd. • Familiarity with AI frameworks (e.g., HuggingFace Transformers, LangChain, scikit-learn, PyTorch); Experience with a production grade codebase with several contributors is a bonus. • Experience in data analysis: visualization, exploration, cleanup. • Knowledge in GenAI tools such as LLM Orchestrations and integration packages, Agents, RAG systems - a bonus.
