Who We Are

Lightning 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.

Our Values

Move Fast: We act with speed and precision, breaking down big challenges into achievable steps.
Focus: We complete one goal at a time with care, collaborating as a team to deliver features with precision.
Balance: Sustained performance comes from rest and recovery. We ensure a healthy work-life balance to keep you at your best.
Craftsmanship: Innovation through excellence. Every detail matters, and we take pride in mastering our craft.
Minimal: Simplicity drives our innovation. We eliminate complexity through discipline and focus on what truly matters.

What We Are Looking For

We 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 Do

Partner directly with customers to design, implement, and deploy end-to-end AI systems and workflows on Lightning’s platform
Translate vague customer objectives into clear technical specifications, proof-of-concepts, and scalable production implementations
Own customer technical engagements end-to-end, from early discovery and architecture through deployment, monitoring, and expansion
Develop and maintain production-grade software systems and services using modern programming languages, with a strong preference for Python
Build reliable, observable systems with strong attention to latency, throughput, quality, scalability, and cost efficiency in production environments
Debug and optimize AI systems across inference infrastructure, model behavior, APIs, and distributed workloads to improve performance and reliability
Work closely with customer engineering teams throughout the full lifecycle of AI deployments, including technical discovery, implementation, deployment, and scaling
Collaborate cross-functionally with Lightning’s product and engineering teams to improve platform capabilities, influence roadmap priorities, and identify opportunities for reusable product improvements
Navigate ambiguity with sound technical judgment, making thoughtful tradeoffs and selecting the right tools and approaches without introducing unnecessary complexity
Demonstrate strong ownership and accountability in execution, with a commitment to delivering high-quality outcomes for both customers and internal teams

What You’ll Need

Required Qualifications

Strong software engineering experience building and maintaining production systems in one or more general-purpose programming languages, with Python strongly preferred
Experience working directly with customers in highly technical environments, such as Forward Deployed Engineering, Solutions Engineering, Applied AI Engineering, Technical Product Engineering, or related roles
Familiarity with AI/ML pipelines and the lifecycle of model development, evaluation, deployment, and monitoring
Experience deploying and operating production AI/ML systems in cloud or distributed environments
Familiarity with modern AI infrastructure and tooling such as Docker, Kubernetes, APIs, model serving systems, or distributed inference workloads
Strong communication and collaboration skills, especially when working through complex technical topics with customers, engineers, and cross-functional stakeholders
Ability to translate business needs into technical solutions and drive projects from initial concept through production delivery
Ability to execute effectively in ambiguous, fast-moving, high-growth environments
Bachelor’s degree in Computer Science, Engineering, Mathematics, or a related field

Nice-to-Haves

Experience building, deploying, or optimizing large-scale AI/ML systems in production environments
Experience with modern AI stacks and tooling such as vLLM, TensorRT, Ray, LangGraph, vector databases, or workflow orchestration systems
Familiarity with inference optimization, distributed systems, or GPU-accelerated workloads
Startup experience or experience operating in highly cross-functional environments
Track record of rapidly shipping proof-of-concepts and production systems while maintaining strong engineering quality
Advanced degree (Master’s or PhD) in Computer Science, Engineering, Mathematics, AI, or a related technical field
