The Opportunity

We're partnering with a well-funded Series A AI startup backed by leading technology investors, building the next generation of AI-powered engineering automation.

The company is developing intelligent AI agents that interact directly with complex engineering software, including CAD (Computer-Aided Design), CAE (Computer-Aided Engineering) and PLM (Product Lifecycle Management) systems.

Their technology enables AI agents to navigate applications, execute engineering tasks and automate workflows that traditionally require hours of manual work.

They're looking for an experienced AI Software Engineer with strong software engineering fundamentals to help build the infrastructure and intelligent systems powering these autonomous agents.

This is a hands-on engineering position with significant technical ownership, working directly on the core product.

What You'll Be Doing

• Design, build and deploy production-grade AI agent systems capable of executing complex, multi-step engineering workflows.
• Develop backend services and orchestration infrastructure supporting autonomous agent execution.
• Build reliable tool-calling frameworks that enable AI agents to interact with external applications and engineering software.
• Implement agent state management, task planning, error handling and recovery mechanisms.
• Develop evaluation and testing frameworks to measure agent performance, reliability and accuracy.
• Optimize LLM-powered systems for latency, cost, scalability and production performance.
• Collaborate closely with engineers and product teams to turn complex engineering processes into automated workflows.
• Take ownership of technical architecture, implementation and production deployment.

What We're Looking For

• 5+ years of professional software engineering experience.
• Strong Python programming skills and computer science fundamentals.
• Experience designing, developing and maintaining production backend systems.
• Strong understanding of distributed systems, APIs, asynchronous processing and system reliability.
• Ability to architect complex software systems and solve challenging technical problems.
• Experience building scalable, maintainable software in fast-moving engineering environments.
• Comfortable taking ownership of projects from initial design through production.

Nice to Have

• Experience developing LLM-powered applications or autonomous AI agents.
• Familiarity with agent orchestration, tool calling, model routing or evaluation frameworks.
• Experience with LangGraph, LangChain or similar agent frameworks.
• Exposure to CAD, CAE, PLM or engineering design software.
• Background in robotics, manufacturing automation, simulation or industrial software.
• Experience working in early-stage startups or building products from the ground up.

Why Join?

• Join a Series A startup with $32M in funding and backing from prominent technology investors.
• Work on a technically challenging product at the intersection of AI, software engineering and industrial automation.
• Build AI agents that interact with real engineering applications, rather than conventional chatbot interfaces.
• Take meaningful ownership of core architecture and product development.
• Work alongside an ambitious engineering team tackling complex automation challenges.
• Help shape a new category of AI-powered engineering software.

Compensation & Location

Base Salary: $200,000–$300,000, depending on experience + Equity

Location: San Francisco, California

Working Arrangement: Full-time, onsite 5 days per week
