About the role

  • Most time is spent hands-on: designing solutions, prototyping, leveraging AI tools, writing reference implementations, and reviewing critical PRs.
  • Architect the Intelligence layer (data, training, learning, reasoning) and the Agentic layer (workflow automation, agentic UX).
  • Make AI workloads observable to engineering and product.

Responsibilities

  • Design and evolve agent-based workflows, enabling reasoning-capable, adaptive, multi-step systems with strong trust patterns (grounding, evals, confidence scoring).
  • Develop and drive evaluation frameworks measuring model quality, agent reliability, drift, and platform effectiveness.
  • Build evaluation frameworks: model quality, agent reliability, drift detection, eval harnesses, observability for AI workloads.
  • Lead the polyglot AI stack: vector search, embeddings pipelines, RAG architectures, agent frameworks, model lifecycle, MLOps.
  • Mentor engineers; raise the technical bar through code review, design review, and technical coaching.
  • AI leverage in how we build and ship.
  • Partner with product to make AI a structural part of how Stratus delivers value, so humans and agents move the roadmap faster together.
  • Drive reliability and the architectural foundation customers can trust for production AI workloads.

Nice to have

  • Background in security architecture and threat modeling for AI systems (prompt injection, data exfiltration, agent abuse) and B2B SaaS.
  • Domain knowledge of MEP, BIM, or construction technology workflows.
  • Prior experience in a Series B / growth-stage company navigating the transition from product-market fit to scale.
  • MCP servers, agent-facing APIs, retrieval-grounded interfaces.
  • Deep proficiency in Python and the modern AI/ML stack (LangChain, LangGraph, PyTorch, sklearn, vector stores, embedding pipelines).
  • Proficiency in C# /.NET and Azure for integration with Stratus's existing platform.
  • Hands-on experience with RAG, fine-tuning, prompt engineering, model training and eval harness design.
  • Hands-on experience with agent frameworks (LangGraph, AutoGen, CrewAI, Semantic Kernel, or equivalent) in production.

Skills

  • designing solutions, prototyping, leveraging AI tools, writing reference implementations, and reviewing critical PRs.
  • model quality, agent reliability, drift detection, eval harnesses, observability for AI workloads.
  • Set engineering standards through working reference implementations, in-repo templates, and patterns AI/ML teams can copy.
  • vector search, embeddings pipelines, RAG architectures, agent frameworks, model lifecycle, MLOps.
  • Drive AI-augmented engineering practice.
  • Personally set the bar.
  • Demonstrated track record of leading AI/ML and agentic architecture across multiple teams or product lines.

Benefits

  • Own the architectural vision and technical roadmap for Intelligence (data, learning, reasoning) and Agentic interfaces, workflows.
  • Comprehensive and competitive health benefits plan Matching 401k contributions 20 days annual PTO Primarily remote work with occasional annual team onsites.

Company info

  • Engage directly with customer-facing teams and customers to ground AI architectural decisions in real workflows.
