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

We are the Product Security team, responsible for the security, reliability, and trust of Raiffeisen Bank’s digital ecosystem.
Our mission is to embed security at every stage of the software development lifecycle and continuously strengthen the resilience of our services.

We are looking for an AI Engineer (Security) — a specialist who combines strong software engineering experience, hands-on expertise with LLMs and AI tools, and a desire to apply these skills within the cybersecurity domain.

In this role, you will design AI-driven solutions to automate security team processes, assess the security of AI systems implemented across business and IT, and help colleagues integrate AI into their daily workflows.

Your future responsibilities:

In this role, you will be responsible for designing and implementing AI solutions for security teams. You will build LLM agents, RAG systems, AI pipelines, and integrations using modern tools.

• Analyzing AI-specific threats
• Managing Shadow AI risks
• Helping Security team to build tools for conducting security reviews of AI products before they go into production
• Defining architectural standards for AI security tooling across the organization
• Mentoring engineering teams on secure AI integration patterns and best practices

• Practical use of AI assistants in development (e.g., GitHub Copilot, Claude Code, Cursor or similar)
• Understanding of RAG architectures: vector databases, embedding models, chunking strategies
• Knowledge of OWASP Top 10 for LLM Applications
• Ability to rapidly prototype — from idea to working PoC in days, not months
• Experience influencing technical direction across multiple teams or projects
• Track record of knowledge transfer — documentation, workshops, or internal enablement

Will be a plus:

• Experience with model fine-tuning
• Knowledge of Cloud AI services: Azure OpenAI, AWS Bedrock, GCP Vertex AI
• Basic understanding of information security processes (SOC, Incident Response, AppSec, GRC)
• Familiarity with NIST AI RMF, EU AI Act, or other AI regulations
• Experience building multi-agent systems
• AI or Cloud certifications

Personal Qualities:

• Practitioner mindset — not just understanding LLMs, but having built real solutions
• Self-sufficiency — ability to take ownership from problem to solution without micromanagement
• Strong communication skills — able to explain complex topics in simple terms to non-AI teams
• Curiosity and adaptability in a fast-evolving AI landscape
• Focus on delivering measurable business value
• Ability to lead by expertise — guiding teams without formal authority
