Job Overview by Ladders

Qualifications

  • 4+ years of experience delivering production software that users rely on daily.
  • Proven ability to deploy AI systems including LLM workflows that interact with real tools.
  • Strong skills in Python and backend or ML systems for production AI applications.
  • Experience with evaluation frameworks and techniques like reinforcement learning and retrieval.
  • Familiarity with observability practices and on-call responsibilities for production systems.
  • Knowledge of CAD, CAE, EDA, or PLM tools is highly advantageous.
  • Background in frontier or applied AI, industrial software, simulation, robotics, or autonomous systems enhances candidacy.

Responsibilities

  • Design and build system architecture that integrates AI agents with CAD, CAE, and PLM tools under security constraints.
  • Own full engineering execution, from architecture choices to production delivery and monitoring.
  • Launch initial production AI workflows for customer use immediately.
  • Develop evaluation and training loops to enhance system performance using real-world data.
  • Work closely with engineers at partner companies to identify system failures and enhance capabilities accordingly.
  • Contribute to and execute the engineering roadmap within live programs.
  • Scale platform adoption across partner firms with a focus on measurable efficiency gains and mentorship.

Benefits

  • Opportunity to shape the engineering culture as the first engineering hire.
  • Potential for significant impact in the rapidly evolving AI and hardware engineering space.
  • Collaboration closely with the CTO, offering direct influence on technical decisions.
  • Hands-on exposure to AI workflows in critical sectors like defense and medical devices.
Full Job Description
About the Role

This is the first engineering hire at a seed-stage AI company building systems that help hardware engineering teams - in defense and medical device sectors - move at the speed of software. You'll partner directly with the CTO to own the full technical stack, set the engineering culture, and ship production AI workflows into live customer programs from day one.
What You'll Do
  • Design and build the system architecture that integrates AI agents with CAD, CAE, and PLM tools while meeting the security requirements of defense and medical customers.
  • Own end-to-end engineering execution: architecture decisions, production delivery, observability, evaluation suites, regression testing, and on-call operations.
  • Ship your first production AI workflow into a live customer program - one that engineers use and depend on regularly.
  • Build evaluation and training loops that improve the system from simulation runs, test data, engineer corrections, and field outcomes, including reinforcement learning grounded in real physics.
  • Embed with engineers at partner companies, identify where the system fails against real deadlines, and translate those learnings into platform capabilities.
  • Contribute to roadmap direction and execute on it reliably inside active engineering programs.
  • Scale the platform across multiple partner companies with measurable cycle-time reduction, and mentor the small team you help grow.
What We're Looking For
  • 4+ years shipping software to production, including systems that real customers depended on daily.
  • Proven track record putting AI in production: shipped LLM agent workflows that call real tools, handle failures gracefully, and are evaluated against rigorous test suites.
  • Strong Python and backend or ML systems engineering skills for production AI systems.
  • Experience designing evaluation frameworks and knowing when to reach for retrieval, fine-tuning, reinforcement learning, or plain software.
  • Comfortable with observability, regression testing, and on-call ownership of production systems.
  • Experience with CAD, CAE, EDA, or PLM tools is a strong plus.
  • Background in frontier AI, applied AI, industrial software, simulation, robotics, or autonomous systems is a plus.
  • Able to earn trust with both customers and domain experts - comfortable learning from experienced field engineers.
  • Willing to travel to partner company sites; low ego, high standards.
Compensation & Benefits

Base salary $150,000-$220,000 USD annually. Visa sponsorship is not available for this role.
Location

Full-time, on-site in New York City, NY.
