Built to protect productivity, the new attack surface, Ent understands not just what users and agents do but why, and intervenes at the moment of risk before incidents occur. Where existing tools see events, Ent sees intent, so security teams can step in at the moment of risk instead of investigating days later. Founded by Lou Manousos and Brandon Dixon, co-founders of RiskIQ (acquired by Microsoft) and the team behind Microsoft Security Copilot, Ent is in production with Global 2000 customers across hospitality, financial services, and defense, and backed by Decibel, Sequoia, Crosspoint Capital, Craft Ventures, Shield Capital, Felicis, and In-Q-Tel. We’re now hiring the team that will define this category.\nHow We Work\nCustomer first. The product and the business are built around problems we’ve watched real security teams struggle with - not the other way around. Every roadmap conversation starts with what a CISO told us last week.\nHumble. No drama. We hire people who share the mission and trust each other to deliver. Teamwork over showmanship. Accountability over politics. The work speaks louder than the person doing it.\n Urgency. The window to build a durable security company in the AI era is open right now and it will not stay open. The shot clock has started. We move at the speed of the people we want to protect.\nAbout the Role\nWe are seeking a Senior AI Engineer to solve hard problems in running AI models where work actually happens: on the endpoint. As people and AI agents take on more of the work inside an enterprise, security has to understand behavior as it unfolds, not days later in an alert queue. At Ent, small, fast models on the endpoint watch the live stream of activity in context and make decisions in milliseconds. Larger reasoning models and agents in the cloud handle deeper investigation and response. You will take models and algorithms from our AI scientists and make them production-grade, with reproducible training, gated evaluation and efficient inference on the edge and in the cloud. Then you will own them in production, so the team can keep pushing into new research. This is a role for an engineer who wants to understand the models they ship, likes working without a map, and wants to help define how AI protects both humans and agents.\nWhat You’ll Achieve (Responsibilities)\nTake models and algorithms from our scientists into production, understanding them well enough to reimplement them correctly (for example Python to C++ or Java) and verify parity with the original.\n\nOwn models after launch, including retraining, monitoring and evaluation, so researchers can move on to the next problem.\n\nDesign evaluation and release gates that decide when a model is safe to ship, catch regressions from model or data changes, and explain shifts in metrics such as precision and recall.\n\nBuild production monitoring for model quality, including drift detection, retrain triggers and ground-truth strategies for unlabeled data.\n\nRun inference within tight latency, memory, CPU and power budgets on the endpoint, and at scale in the cloud, using quantization, distillation, batching and caching.\n\nBuild the pipelines that connect the two layers, so behavioral baselines and context learned in the cloud flow reliably back to endpoints.\n\nBuild the infrastructure for training and experimentation (datasets, reproducible training, CI/CD for models) and keep it simple enough for a fast-moving team.\n\nWhat You’ll Bring (Requirements)\nMust Have\nA track record of owning and designing whole systems end to end, shown by growing scope across roles or companies.\n\nExperience training, evaluating and deploying your own models in production. Integrating LLM APIs alone is not enough for this role.\n\nThe ability to take someone else's algorithm, understand the math and logic behind it, and turn it into correct, tested production code.\n\nA strong grasp of model evaluation: designing evals beyond simple tests, reasoning about regressions, and knowing how you'd tell that a model was ready to ship.\n\nStrong engineering skills in Python and at least one systems or backend language (C/C++, Java, Rust or Go).\n\nCuriosity beyond your own job description, including about where AI and security are heading.\n\nComfort with ambiguity: you define the problem, then solve it, and you close gaps without being asked.\n\nNice to have\nEdge or resource-constrained inference (ONNX Runtime, llama.cpp, Core ML, TensorRT, OpenVINO or similar), with results you can quantify.\n\nBuilding and operating data or inference pipelines at scale, with a solid grasp of cost and latency tradeoffs.\n\nBuilding infrastructure without a big-company platform behind you, at a startup or with your own setup.\n\nUsing AI coding agents as a core part of your workflow, with judgment about checking what they produce.\n\nProduction LLM or agentic systems, including evaluating probabilistic outputs, agent harnesses and MCP.\n\nBackground in security: endpoint detection, DLP, behavioral analytics, or protecting AI agents.\n\nOur Benefits\nDistributed workplace. While we have positions we hire for in our SF office, we also hire remotely across North America.\n\nOwn a piece of the journey. Every teammate gets meaningful equity on top of their salary.\n\nWe’ve got you covered. Generally, we pay 90% of your medical, dental, and vision is paid by Ent. We also cover 75% for your dependents.\n\nTake the time you need. Our flexible PTO lets you recharge, travel, or just take a breather.\n\nFamily matters. 14 weeks of fully paid parental leave (birth, adoption, or foster)!\n\nLive well. A $100 monthly lifestyle account to spend on what keeps you healthy and happy - fitness, wellness, learning, and more.\n\nSet up your space. A $500 home office stipend when you join as a remote employee.\n\nDiversity & Accommodations\nWe’re committed to building a diverse, inclusive, and equitable workplace where people of all backgrounds, identities, experiences, and abilities are welcomed, valued, and supported. We recognize there is no single path to success and value nontraditional career journeys and diverse perspectives as key to building stronger, more innovative teams.\nWe strive to ensure an inclusive experience at every stage of hiring and are happy to provide reasonable accommodations. If you require accommodations or accessible formats at any point during our process, please let your recruiter know. As an equal opportunity employer, our hiring process is designed to put you at ease and help you do your best work. If there’s anything we can do to improve your experience, we’re always open to feedback.","description_format":"text","description_chars":6714,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Home
