About the role

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

πŸ§‘πŸ»β€πŸ’» 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
