Role
Who you are
- 6+ years of professional software engineering experience with a strong foundation in backend or full-stack development
- Demonstrated experience building and shipping production-grade products using LLMs and agentic frameworks
- Proficiency in TypeScript and/or Python
- Deep understanding of prompt engineering, context management, and LLM reasoning patterns
- Experience with tool-use, function calling, and agent orchestration (e.g. LangChain, LlamaIndex, Claude Code, or custom implementations)
- Ability to design and execute structured evals to measure and improve AI system performance
- Strong communication skills and comfort working cross-functionally with both technical teams and non-technical stakeholders
- Must be able to obtain and maintain security clearance
Desirable
- Experience with MCP (Model Context Protocol) server development and integration
- Familiarity with vector databases (e.g. pgvector, Pinecone, Weaviate)
- Experience with fine-tuning, RLHF, or model evaluation pipelines
- Background in ML fundamentals: embeddings, transformers, attention mechanisms
- Exposure to structured output generation and LLM-based data extraction
- Experience working with code generation agents (e.g. Claude Code, Cursor, Devin-style systems)
- Familiarity with AWS and serverless infrastructure for AI workloads
- Experience working in or alongside government, defense, or regulated environments
- Interest or background in the AEC (architecture, engineering, construction) industry
What the job involves
- ICON is looking for a pragmatic builder who has made the leap from traditional software engineering into the emerging world of agentic AI development
- As an AI Software Engineer at ICON, you will be responsible for designing and shipping AI-powered tools, workflows, and autonomous agents that accelerate ICON's construction technology platform
- This role reports to the Sr
- Director, Defense Technology Programs and is available for remote work with periodic travel to ICON HQ in Austin, TX as projects require
- Design and build agentic AI systems that automate complex, multi-step workflows across ICON's software platform
- Develop LLM-powered features and products using state-of-the-art foundation models and APIs (e.g. Anthropic, OpenAI)
- Architect and implement multi-agent pipelines, tool-use systems, and Model Context Protocol (MCP) integrations
- Build robust RAG systems including document ingestion, chunking strategies, embedding pipelines, and vector retrieval
- Collaborate with software and domain teams to identify high-leverage AI automation opportunities and translate them into shipped products
- Own the full development lifecycle of AI features: prototyping, evaluation, deployment, and iteration
- Serve as a technical resource and informal mentor on agentic AI best practices across the engineering organization
- Stay at the leading edge of the agentic AI landscape and bring emerging techniques into production
Our take
We are currently facing a global housing crisis, with over 1B people living without adequate shelter. ICON is a 3D-powered construction company that is setting out to redesign the homebuilding industry.
ICON develops advanced construction technologies by using 3D printing robotics, software and advanced materials. Once operating a waitlist for home reservations, the company now offers homes for sale in Texas. Since its 2017 launch, ICON has raised significant funding, reflecting the strong interest in its innovative approach to homebuilding.
The sheer scale of what can be done with ICON’s technology is extraordinary, so much so that the company has a contract with NASA to develop systems to build on the Moon and Mars. It also partners with large-scale residential communities, not-for-profit housing, and works on special projects like rocket landing pads. These are undoubtedly exciting times for ICON, and it’ll be interesting to see what comes next for the company after its substantial Series C funding round raised in 2025.
