Requirements and responsibilities
● 7+ years of experience in Software Engineering;
● Strong experience designing complex distributed systems and service-oriented architectures;
● Hands-on experience with AI/ML system architecture, including LLM-based systems, inference layers, vector search, and data pipelines;
● Solid understanding of LLM reasoning, tool calling, agent orchestration, and human-in-the-loop workflows;
● Ability to decompose complex platforms into services, modules, and integration layers, and to define clear boundaries between LLM, ML, deterministic logic, and human validation;
● Strong understanding of data architecture: data lakehouse, vector databases, object storage, and federated queries;
● Experience designing for scalability, latency, throughput, and fault tolerance;
● Experience designing secure systems for sensitive or critical data, with awareness of AI security risks (prompt injection, unsafe tool execution, data leakage, runtime protection);
● Strong documentation skills: architecture diagrams, ADRs, technical specifications, and integration flows;
● Ability to work with incomplete information, technical uncertainty, and evolving requirements;
● High level of ownership, technical leadership, and proactive decision-making;
● Upper-Intermediate level of English.
● Experience in the Defense/MilTech and AI domains;
● Experience with on-premise/hybrid infrastructure.
● Design end-to-end system architecture for the AI-based data analysis platform;
● Decompose the system into services: agent runtime, orchestration, inference layer, data layer, security layer, and integrations;
● Define boundaries between LLM reasoning, ML processing, deterministic rules, and human decision-making;
● Design architecture for AI recommendations, next-best-action logic, semantic search, and data analysis workflows;
● Design a scalable inference architecture and model-serving approach;
● Define latency, throughput, fault-tolerance, and scaling strategy from single-node to cluster deployment;
● Design data architecture for ingestion, storage, cataloging, vector search, querying, and access control;
● Define the orchestration approach for long-running AI/agent workflows;
● Establish security, auditability, runtime protection, and data leakage prevention principles;
● Collaborate with engineering, DevOps, ML/data engineers, product, and business stakeholders;
● Support technical discovery, feasibility analysis, POC creation, concept validation, estimation, and roadmap planning;
● Identify architectural risks, dependencies, constraints, and mitigation options;
● Prepare and maintain architecture documentation, diagrams, ADRs, and technical recommendations;
● Guide engineering teams on implementation approach, scalability, performance, and architectural standards.
