Design and build AI-driven agents that emulate adversarial behaviours such as lateral movement, privilege escalation, and persistence.
Develop core simulation and orchestration components in Go (primary language) and integrate with in-house AI models.
Model and simulate attack paths across complex enterprise environments (identity, endpoint, network, and cloud).
Collaborate with red-teamers, researchers, and data scientists to translate threat intelligence and real attack TTPs into executable logic.
Contribute to architecture decisions, scalability, and performance optimization for distributed simulations.

As a Senior Backend & LLM Applications Developer at our company, you will design and build scalable backend systems while integrating advanced AI capabilities into production. You will work with Large Language Models (LLMs), agentic AI, and AI agents, making key architectural and technical decisions that shape how AI powers our products for the Care Network.

What Youll Do
Design and develop scalable backend services and cloud-based infrastructure (AWS) using microservices architecture
Take end-to-end ownership of complex backend systems and development projects, from design to production
Drive performance, reliability, security, and scalability of core platform services
Integrate AI and LLM capabilities into backend systems, including prompt optimization and production readiness
Collaborate with Product and Data teams to deliver AI-enabled features
Research, prototype, and lead the adoption of new backend technologies, with selective adoption of AI models and tools into production.

We're building our company's Cyber Threat Intelligence platform - an AI-first product that harvests, contextualizes, and serves threat intelligence at scale. We're looking for a Python-native backend engineer to own the infrastructure that makes this possible.
You'll design and build the systems that power both agentic AI workloads and large-scale data orchestration - exposing CTI insights as a service to UI components, APIs, and autonomous agents across the company ecosystem. This is a greenfield opportunity where you'll shape foundational architecture decisions on a new product with a small, high-impact team.
The Responsibilities
Shape and build our data lake architecture, orchestration layer, and data access patterns.
Build the tooling and infrastructure that enables AI agents to consume and reason over threat data.
Develop systems that harvest data from open and dark web sources, cross-reference signals, and contextualize raw intelligence into actionable insights.
Serve curated CTI data to various consumers - dashboards, internal services, and other agents in the company platform.
Instrument complex workflows with tracing and metrics - when things break in production, we need visibility to understand why.
Create developer tooling and experiences that make the platform usable for other engineers building on top of it.
