Job description

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.
