Senior AI Fullstack Developer at Marvik in AR

Join as a Software Engineer to build AI full-stack solutions and shape an engineering culture that values autonomy, creativity, and technical excellence. 🚀

🌟 What do we offer?

• A central role in the team that defines the next products, not just maintains the existing ones
• End-to-end ownership of the agentic AI layer on top of what Labs ships
• AI-assisted development as a first-class practice, Claude Code, Cursor, Copilot, with the autonomy to exercise real engineering judgment
• Modern, multi-cloud stack: MongoDB + SQL, Azure + AWS
• Real influence over architecture, technical standards, and engineering culture beyond your immediate team
• A high-bar technical environment where your architectural decisions impact multiple teams and products

🧑🏻‍💻 Responsibilities:

• Set architectural direction for products emerging from Labs, from prototype to production
• Design and build production-grade agentic workflows: retrieval, tool use, multi-step planning, human-in-the-loop checkpoints, and safety guardrails
• Be the senior technical voice in architectural decisions that span multiple teams
• Establish technical standards and engineering practices that extend across the organization
• Make significant individual contributions to the SaaS product across Azure and AWS
• Collaborate with product, design, and engineering across the full SDLC
• Mentor and guide engineers and actively influence engineering culture
• Ensure performance, quality, and responsiveness of customer-facing applications and the agentic systems built on top of them
• Implement and maintain modern automated testing practices, including evals for AI components
• Contribute to modernization and consolidation of legacy surfaces as integration touch points emerge

🤝 If you have:

• 8+ years of professional software development experience, with 3+ years in senior, lead, or principal roles
• Deep code fluency: ability to pick up an unfamiliar codebase in any mainstream language and form a defensible opinion in days, not weeks, language is a tool, not an identity
• Strong working command of both Azure and AWS and the tradeoffs across container orchestration, serverless, messaging, identity, and managed data stores
• Kubernetes in production
• Solid command of both SQL and NoSQL systems
• Demonstrable AI engineering chops: has shipped LLM-powered features to production; comfortable with retrieval, embeddings, tool calling, structured outputs, and cost/latency tradeoffs
• Has designed agentic workflows end-to-end: planning, tool use, evaluation, failure-mode analysis, human-in-the-loop; can articulate when an agent is the right answer and when a deterministic pipeline is
• Proven track record of leading architectural initiatives and influencing decisions across teams
• Strong technical leadership and mentoring experience
• Solid grasp of SOLID, DRY, KISS, YAGNI, and TDD; applies them when warranted
• Comfortable ramping into the current stack: C#/.NET backend, Node.js/TypeScript and Vue.js frontend, and into whatever Labs ships next
• Advanced English

🦾 It’s a plus:

• Working familiarity with Model Context Protocol (MCP), agent frameworks, and eval frameworks
• Experience deploying inference workloads on Azure (AI Foundry / Azure OpenAI) and/or AWS (Bedrock, SageMaker)
• Experience with Autodesk products and APIs (AutoCAD, Revit, Fabrication, BIM 360 Docs, Forge / APS)
• Construction, MEP, or manufacturing domain knowledge
• Experience leading large-scale system migrations or architectural transformations
• Familiarity with modern serverless technologies on either cloud
• Track record of establishing technical standards across engineering organizations
• Understanding of event-driven architectures and message-based integration
