OVERVIEW We’re looking for a Senior Software Engineer with a passion for AI to join us in our mission of bringing the ION Factory OS to next-generation hardware builders around the globe. This role is based in Los Angeles, CA (HQ in El Segundo). Are you excited by the opportunity to build AI-powered software that accelerates the development of eVTOLs, rockets, robots, and autonomous vehicles? RESPONSIBILITIES & DUTIES - Lead the design, implementation, and optimization of production-ready AI systems within the ION Factory OS. - Ship customer-facing features that directly impact manufacturing workflows, including AI-driven functionality (e.g., generative procedure creation, anomaly detection, recommendations) and core product features not reliant on AI. - Architect and maintain scalable software systems, including AI/ML pipelines and broader product infrastructure. - Design and implement AI features using retrieval-augmented generation (RAG) pipelines to deliver context-aware insights and recommendations. - Leverage Model Context Protocol (MCP) and similar frameworks to connect AI models seamlessly with structured/unstructured data sources and external tools. - Collaborate with product managers and customers to translate real-world challenges into robust software solutions. - Partner with data engineering to process and transform structured and unstructured manufacturing data into usable formats. - Ensure reliability, scalability, and maintainability of all systems in production, leveraging CI/CD and cloud-native workflows. - Stay ahead of advancements in software engineering and AI, bringing the best practices into shipped product features. - Mentor junior engineers and help raise the technical bar across the team. MINIMUM QUALIFICATIONS & SKILLS - 7+ years of professional software engineering experience, including 3+ years shipping AI/ML-powered products into production. - Proven track record of building and shipping customer-facing applications (AI and non-AI) that deliver measurable business value. - Experience architecting scalable systems on cloud platforms (AWS, Azure, GCP). - Expertise in data modeling, preprocessing, and model evaluation at scale. - Familiarity with generative AI models (LLMs, diffusion models, GANs) and their real-world applications. - Strong knowledge of APIs and modern software design patterns for integrating AI into SaaS products. - Excellent problem-solving, communication, and cross-functional collaboration skills. - Passion for AI innovation paired with the ability to deliver non-AI product functionality when needed. DESIRED QUALIFICATIONS - Experience building AI systems for real-time, low-latency, or edge deployments. - Familiarity with modern data governance, privacy, and compliance standards (SOC2, GDPR, ITAR). - Hands-on experience with retrieval-augmented generation (RAG) for building AI systems that combine large language models with external knowledge sources. - Understanding of and/or experience with Model Context Protocol (MCP) or similar emerging standards for connecting AI systems with data and tools. - Customer-facing experience gathering requirements, presenting solutions, and demonstrating value. - Contributions to open-source projects or published research in applied AI/ML. - Experience mentoring engineers and contributing to engineering best practices. Benefits & Perks - Health Insurance; medical, vision, dental, & life insurance. - Paid Parental Leave. - Employee Stock Option Plan. - Team outings, group lunches, open office, happy hours. - Paid holidays, sick days. - Flexible Friday and PTO. - 401K.
