AI Engineer (GenAI / Agentic Systems) - Senior Software Engineer
We are seeking a Senior AI Engineer (m/f/n) who combines strong software engineering fundamentals with hands-on experience building production GenAI solutions, including agentic workflows and Retrieval-Augmented Generation (RAG).
This is an engineering and orchestration role focused on integrating LLM capabilities into enterprise systems - not a traditional model-training/ML research role.
5+ years of professional software development experience (ideally 7+ years across backend/API/integration and cloud platforms).
Proven ability to ship production-grade LLM applications (RAG, tool/function calling, agent orchestration) with reliability, security, and observability.
Strong ownership mindset and passion for AI engineering - curiosity, experimentation, and a drive to continuously improve the product and the team.
Excellent communication and collaboration skills; ability to guide, mentor, and unblock other engineers as we build out an AI engineering capability.
Required Skills, Experience, and Attitude:
Core Engineering
Strong software engineering background (not a research-only data science profile): designing, building, and operating production systems.
Proficiency in at least one backend language used for AI systems (Python preferred) and comfort integrating with enterprise stacks (C#/.NET is a plus).
Hands-on experience building and integrating RESTful APIs; GraphQL experience is a plus.
Strong understanding of distributed systems fundamentals: concurrency, async I/O, resiliency/retries, rate limits, caching, and performance optimization.
Experience integrating with external services and internal platforms via APIs and event-driven patterns.
Solid database fundamentals (SQL design, performance, migrations); experience with vector search is required, and hybrid search stores is a plus.
AI Engineering (Agents & RAG)
Hands-on experience building LLM-powered applications end-to-end: prompt design, tool/function interfaces, structured outputs, and streaming user experiences.
Experience with RAG systems: document ingestion pipelines, chunking/metadata, embeddings, retrieval strategies, grounding, and evaluation.
Experience with agentic frameworks and orchestration concepts (planning, routing, tool use, human-in-the-loop interruptions). Frameworks may include LangGraph, LangChain, Microsoft Semantic Kernel, or equivalent.
Understanding of LLM application quality and safety: evaluation approaches, hallucination mitigation, prompt/version management, and guardrails for sensitive data.
Experience working with model platforms (e.g., Azure OpenAI/OpenAI or similar) and designing for reliability (timeouts, fallbacks, quotas).
Cloud, Data, and Observability
Strong knowledge of Azure cloud services used for enterprise AI solutions (e.g., Functions, Storage, Key Vault, App Configuration, Application Insights).
Experience with search and retrieval services (Azure AI Search or similar) and building scalable, network-bound workloads.
Ability to design systems with production observability: structured logging, tracing, metrics, and incident-friendly debugging.
Testing & DevOps
Strong background in unit and integration testing; ability to build and maintain AI evaluation harnesses (golden sets, regression tests, automated checks).
Hands-on experience with CI/CD and automated deployments (Azure DevOps preferred), including containerization (Docker).
Strong understanding of source code version control with Git/GitHub.
Familiarity with authentication/authorization patterns (JWT/OAuth/OIDC) and secure secret management.
Soft Skills & Attitude
High ownership and a builder mindset: you take ideas from ambiguous problem statements to working solutions.
Passion and curiosity for AI engineering; you actively explore new approaches and share learnings with the team.
Strong written and verbal communication; able to explain complex systems clearly to engineers and non-engineers.
Highly collaborative and effective in distributed teams across time zones; comfortable pairing/mobbing when needed.
Ability to lead by influence: mentor others, drive alignment on architecture, and raise the team's bar for quality.
Preferred Experience
Direct experience with LangGraph and/or LangChain for multi-agent workflows.
Familiarity with emerging agentic ecosystem concepts/protocols (e.g., MCP, A2A, ADK or similar).
Experience integrating AI services into .NET (ASP.NET Core) applications or building AI microservices that serve enterprise applications.
Experience with event-driven architectures (service bus, event hubs) and real-time updates/streaming to UI.
Experience working with tax/enterprise document corpora and governance constraints (PII, retention, access control).
Responsibilities:
Design, build, and operate agentic AI services that orchestrate tools, workflows, and integrations across cloud systems and enterprise data sources.
Implement and continuously improve RAG pipelines for tax artifacts and internal knowledge, including ingestion, retrieval tuning, and evaluation.
Integrate AI workflows with existing internal platforms (e.g., assistant frameworks) and back-end services through robust APIs.
Define and maintain tool/function schemas and orchestration patterns; implement streaming updates, interrupts, and human-in-the-loop steps as needed.
Partner with other engineers to set direction, mentor, and unblock the team - helping establish strong foundations for the AI initiative.
Build in quality from day one: automated tests, evaluation checks, monitoring/telemetry, and performance optimization for network-bound workloads.
Participate in Agile ceremonies (daily scrums, refinement/grooming, planning) and collaborate through peer review, pair programming, and strong documentation.
Apply best practices, design principles, and security standards throughout the SDLC, with a focus on reliability and responsible AI.
