Senior AI/ML Engineer

COMPANY
Arcyn is creating an AI-powered compliance checker for architectural design — an Autodesk Revit plugin that automatically checks designs against regulations. Architects get instant feedback on violations as they design in Revit, instead of waiting weeks for permit reviewers to tell them what’s wrong.

We’ve just closed the seed round and are building the core technical team. We’re now a team of 4 with a track record of building complex technical products. This is a chance to join at the ground floor, shape product architecture and solve genuinely hard AI problems.

KEY RESPONSIBILITIES

• Design and maintain modular, multi-step ML and LLM workflows for compliance automation, combining classical ML techniques with LLM-based components where appropriate
• Lead the data science and ML work end-to-end: problem framing, data exploration, experimentation, evaluation, and productionization
• Integrate multiple LLM providers (e.g., OpenAI, Anthropic, Perplexity) into a cohesive orchestration pipeline.
• Build cost-optimized batch processing and intelligent API request strategies.
• Translate complex regulations into structured, machine-executable logic.
• Develop and validate automatically generated code to ensure correctness, safety, and performance.
• Collaborate with domain experts to refine logic interpretation and edge case handling.
• Maintain high-quality, well-structured Python codebases with clear separation of concerns.

REQUIREMENTS
Must-have:

• 8+ years of professional experience in data science, ML engineering, or closely related roles
• Strong foundation in ML/DS fundamentals: feature engineering, model selection, evaluation methodology, error analysis, and handling messy real-world data
• Strong Python skills, including experience writing production-grade, modular code.
• Proven track record building multi-step LLM workflows (LangChain, LangGraph, or similar).
• Experience in structured code generation and validation.
• Strong debugging skills and comfort working with complex, evolving systems.

Nice-to-have:

• Experience with compliance automation, technical regulations, or domain-specific rule translation.
• Familiarity with Pydantic models or other type-safe data management frameworks.
• Background in developer tooling or systems requiring high reliability and reproducibility.
• Experience optimizing LLM API usage for both cost and speed.

WHAT WE OFFER

• Full-time remote role aligned with CEST
• B2B set-up via SP account
• Flexible work arrangements and competitive compensation
• Freedom to architect solutions using the best tools for the job
• Collaboration with a multidisciplinary, innovation-driven team
• Opportunity to shape a new AI product from the ground up at an early stage
