Job Description

About SimbianSimbian is building an Agentic AI platform for cybersecurity. Our AI agents automatesecurity operations and provide customers with 10x leverage across critical securityworkflows.

Our initial use cases include:

AI-based SOC alert triage and investigation

AI-based Penetration Testing

Founded by repeat successful security founders, Simbian brings together a strong team ofengineers, security experts, and operators working on some of the hardest problems at theintersection of cybersecurity and AI.Our core values are excellence, replication, and intellectual honesty. We believe inbuilding exceptional technology, sharing what we learn, and being honest about whatworks—and what doesn't.

The Role

We are looking for an Applied AI Engineer to help build the systems that make our AIagents powerful, reliable, and useful in real-world cybersecurity environments.This role sits at the intersection of backend engineering, distributed systems, andapplied AI.You will build the backend infrastructure that powers our agents while also working directlyon agent behavior—improving how agents reason, use tools, retrieve context, handlefailures, and complete complex tasks.The goal isn't simply to build models or backend services in isolation. It's to turn AIcapabilities into dependable production systems that solve real customer problems.You'll work closely with research, engineering, product, and security teams to take ideasfrom experimentation to production and measure whether they improve agentperformance.

Requirements

Applied AI & Agent Systems

Design and iterate on AI agent behaviors across real-world cybersecurity andsoftware engineering workflows.

Build multi-step agent workflows with tool calling, branching logic, retries,validation, and human-in-the-loop controls.

Develop tool schemas, execution strategies, context construction, memory, andretrieval mechanisms that improve agent performance.

Experiment with prompting, model-facing strategies, tool-use patterns, and contextengineering.

Analyze agent failures and systematically turn failure modes into product andengineering improvements.

Build guardrails, policy layers, and safe-execution mechanisms for agents operatingin security-sensitive environments.

Help define what "good" looks like for an agent completing complex tasks end-toend.

Evaluation & Agent Performance

Design and run evaluations to measure agent quality, reliability, regressions, andedge cases.

Build evaluation pipelines, test harnesses, scoring frameworks, and goldendatasets.

Create feedback loops that bring real-world task data and production failures backinto evaluation and development.

Analyze production traces and agent behavior to identify opportunities for improvingsolve rate, usefulness, and reliability.

Work with research and engineering teams to translate experimental improvementsinto measurable production gains.

Design and build scalable backend services that power AI agents and cybersecurityworkflows.

Build high-scale, multi-tenant systems that securely support multiple customerenvironments.

Work with microservices, asynchronous execution, event-driven architectures, anddistributed systems.

Build ingestion, indexing, retrieval, and agent-memory layers for large volumes ofsecurity data.

Design reliable execution systems with strong observability, traceability,monitoring, and data-quality guarantees.
