Ema builds AI Employees for HR, IT and Finance. Our AI Employees take on the busy work across the employee experience, from recruiting, onboarding and benefits to IT support, invoice processing and payroll, so people can spend their time on work that needs them. Founded by former executives from Google, Coinbase, Flipkart, and Okta, our team includes engineers from premier tech companies and graduates of Stanford, MIT, UC Berkeley, CMU, and IITs.
We are backed by industry leading investors including Accel, Naspers/Prosus, Creaegis, Section32, and angels like Sheryl Sandberg and Dustin Moskovitz. Headquartered in Silicon Valley and with offices in London, Bangalore and Vancouver, Ema is at the frontier of what Agentic AI can do in production. We ship real systems that run real business processes at scale.
Ema builds AI agents that act on sensitive enterprise data and systems. You’ll make sure the agents, and the platform they run on, are secure by design. You’ll build security controls for autonomous agents operating across multi-tenant enterprise environments, including cloud, on-prem and air-gapped deployments. You’ll solve zero-trust problems where the code isn’t static logic but non-deterministic models making live API calls against sensitive customer data. Our agents orchestrate 100+ LLMs, call third-party tools through MCP, execute code in sandboxes and drive headless browsers, and each of those is an attack surface you’ll help define.
Role OverviewWhat you’ll ownThreat model new AI agent features before launch: direct and indirect prompt injection, jailbreaks, data exfiltration through agent outputs, and over-privileged tool use
Design guardrails for agentic workflows: least-privilege tool and connector scopes, human-in-the-loop approvals for high-risk actions, and output filtering
Enforce tenant and data isolation across retrieval (RAG), context stores, and model calls, so no customer’s data leaks into another’s context
Secure the AI supply chain: model and provider vetting, third-party MCP servers and connectors, prompt and config versioning
Run AI red-team exercises and build automated adversarial tests (prompt injection suites) into CI
Security baselines for Kubernetes and cloud infrastructure: RBAC, network policies, workload identity, secrets management, per-tenant network isolation
Security in CI/CD: IaC scanning, SAST and dependency scanning, policy-as-code guardrails
AI-aware detection with our current technology and tooling: logging prompts, tool calls and agent actions, and alerting on anomalous agent behavior
Partner with the Security & Compliance Lead on technical controls and evidence for SOC 2 Type II, ISO 27001, HIPAA and ISO 42001, plus the NIST AI RMF
5+ years in cloud security, application security, or DevSecOps (GCP/Azure Preferred)
Deep hands-on Kubernetes and cloud security experience
Security automation with IaC (Terraform/Helm) and Python or Bash.
A working understanding of LLM application risks (OWASP Top 10 for LLM Applications) and how agentic systems fail
Comfortable influencing engineers without formal authority
Hands-on experience securing LLM, RAG, or agentic systems in production
AI red teaming, or familiarity with MITRE ATLAS
CNAPP/CSPM tooling, SIEM/detection engineering
Contributions to AI security research, open-source tools, or CTFs
At the frontier of AI: Secure agentic systems that are driving real enterprise transformation.
Security is the product: Enterprise CISOs evaluate our security before they buy. Here it’s a core feature, not a checkbox.
Security as a peer, not a gate: You’ll report to the Security & Compliance Lead and partner directly with Engineering and Product leadership. You’ll sit in design reviews from day one and have a real say in what ships.
Ownership: Help set the baseline for enterprise trust in AI agents and shape the security DNA of a category-defining company.
Elite talent: Work with engineers and researchers from top-tier tech companies who value deep execution
High Bar on Quality: We value excellence and expect world-class execution.
Ownership & Accountability: We take full responsibility for our work and outcomes.
Impact-Driven Approach: We set ambitious goals and measure success through real-world impact.
No Hierarchy, Just Execution: Everyone is an individual contributor focused on delivering results.
Compensation offered will be determined by factors such as location, level, job-related knowledge, skills, and experience. Certain roles may be eligible for variable compensation, equity, and benefits.
