Forward Deployed Engineer

Forward Deployed EngineerLondon, England, United Kingdom; New York, New York, United States; San Francisco, California, United States; Seattle, Washington, United StatesWho We AreLightning AI is the company behind PyTorch Lightning. Founded in 2019, we build an end-to-end platform for developing, training, and deploying AI systems—designed to take ideas from research to production with less friction.Through our merger with Voltage Park, a neocloud and AI Factory, Lightning AI combines developer-first software with cost-efficient, large-scale compute. Teams get the tools they need for experimentation, training, and production inference, with security, observability, and control built in.We serve solo researchers, startups, and large enterprises. Lightning AI operates globally with offices in New York City, San Francisco, Seattle, and London, and is backed by Coatue, Index Ventures, Bain Capital Ventures, and Firstminute.What We Are Looking ForWe are seeking an experienced Forward Deployed Engineer to partner directly with customers to architect, build, and deploy production AI systems and workflows on Lightning AI's platform. In this role, you will own the customer journey from early exploration through production deployment, translating ambiguous business goals into reliable, observable systems with clear quality, latency, scalability, and cost outcomes.This role sits at the intersection of software engineering, research engineering, AI infrastructure, product thinking, and customer engagement. You'll work closely with customer engineering teams as well as Lightning's internal product and engineering organizations to deliver production-ready AI systems that help customers realize value quickly and scale with confidence.This is a hands-on engineering role that combines software development, AI infrastructure, technical customer engagement, and product thinking. Successful candidates will be highly technical, customer-oriented builders who thrive in fast-moving environments and enjoy solving ambiguous, real-world AI systems problems.This role is based in one of our hubs (New York City, San Francisco, Seattle, or London), with a minimum of 2 in-office days per week and occasional team and company offsites.What You'll DoPartner directly with customers to design, implement, and deploy end-to-end AI systems and workflows on Lightning's platformTranslate vague customer objectives into clear technical specifications, proof-of-concepts, and scalable production implementationsOwn customer technical engagements end-to-end, from early discovery and architecture through deployment, monitoring, and expansionDevelop and maintain production-grade software systems and services using modern programming languages, with a strong preference for PythonBuild reliable, observable systems with strong attention to latency, throughput, quality, scalability, and cost efficiency in production environmentsDebug and optimize AI systems across inference infrastructure, model behavior, APIs, and distributed workloads to improve performance and reliabilityWork closely with customer engineering teams throughout the full lifecycle of AI deployments, including technical discovery, implementation, deployment, and scalingCollaborate cross-functionally with Lightning's product and engineering teams to improve platform capabilities, influence roadmap priorities, and identify opportunities for reusable product improvementsNavigate ambiguity with sound technical judgment, making thoughtful tradeoffs and selecting the right tools and approaches without introducing unnecessary complexityDemonstrate strong ownership and accountability in execution, with a commitment to delivering high-quality outcomes for both customers and internal teamsWhat You'll NeedRequired QualificationsStrong software engineering experience building and maintaining production systems in one or more general-purpose programming languages, with Python strongly preferredExperience working directly with customers in highly technical environments, such as Forward Deployed Engineering, Solutions Engineering, Applied AI Engineering, Technical Product Engineering, or related rolesFamiliarity with AI/ML pipelines and the lifecycle of model development, evaluation, deployment, and monitoringExperience deploying and operating production AI/ML systems in cloud or distributed environmentsFamiliarity with modern AI infrastructure and tooling such as Docker, Kubernetes, APIs, model serving systems, or distributed inference workloadsStrong communication and collaboration skills, especially when working through complex technical topics with customers, engineers, and cross-functional stakeholdersAbility to translate business needs into technical solutions and drive projects from initial concept through production deliveryAbility to execute effectively in ambiguous, fast-moving, high-growth environmentsBachelor's degree in Computer Science, Engineering, Mathematics, or a related fieldNice-to-HavesExperience building, deploying, or optimizing large-scale AI/ML systems in production environmentsExperience with modern AI stacks and tooling such as vLLM, TensorRT, Ray, LangGraph, vector databases, or workflow orchestration systemsFamiliarity with inference optimization, distributed systems, or GPU-accelerated workloadsStartup experience or experience operating in highly cross-functional environmentsTrack record of rapidly shipping proof-of-concepts and production systems while maintaining strong engineering qualityAdvanced degree (Master's or PhD) in Computer Science, Engineering, Mathematics, AI, or a related technical fieldCompensationWe are committed to offering competitive compensation that reflects the value each team member brings to our mission.
