About Us At LangChain, our mission is to make intelligent agents ubiquitous. We build the foundation for agent engineering in the real world, helping developers move from prototypes to production-ready AI agents that teams can rely on. We began as widely adopted open-source tools and have grown to also offer a platform for building, evaluating, deploying, and operating agents at scale. With $125M raised at Series B from IVP, Sequoia, Benchmark, CapitalG, and Sapphire Ventures, we’re at a stage where we’re continuing to develop new products, growth is accelerating, and all team members have meaningful impact on what we build and how we work together. LangChain is a place where your contributions can shape how this technology shows up in the real world. Today, our platform includes LangSmith (Observability, Evaluation, Deployment, Fleet, and Sandboxes), our open source frameworks (LangChain, LangGraph, and Deep Agents), and the newly launched LangSmith Engine for autonomous agent improvement. We have 100M+ monthly open source downloads, 6,000+ active LangSmith customers, and 5 of the Fortune 10 use LangSmith in production (+ 35% of the Fortune 500 overall), including teams at Klarna, Clay, Coinbase, Workday, Lyft, Cloudflare, Harvey, Rippling, Vanta, LinkedIn, Monday.com, Nvidia, and Bridgewater. About the Team The Deployed Engineering team works directly with companies building and running AI agents in production, helping turn ideas and prototypes into systems teams can rely on. This is a hands-on, highly technical team that partners closely with customer engineers across the full lifecycle, from pre-sales evaluations to post-deployment advisory work. The focus is on achieving the technical win, co-designing agent architectures, and helping customers operate agents reliably at scale using the LangChain suite. Deployed Engineers sit at the intersection of engineering, product, and go-to-market , shaping how LangChain is adopted in the field and feeding real-world insi

About the team The Deployed Engineering team is the technical front line of our go-to-market motion. We partner with account executives from the first technical conversation through production rollout, helping companies evaluate LangChain, prove it out on their hardest use case, and get agents running reliably at scale. This is a hands-on, highly technical team. Solutions Engineers own the technical win: scoping evaluations, designing POCs that mirror real workloads, answering the deep architecture questions that decide a deal, and staying with the customer after signature to make sure what we sold actually ships. We sit at the intersection of engineering, product, and sales.

Hyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production. The Company’s primary focus is to develop distributed power generators that can operate on various fuel sources to future-proof against an ever-changing energy economy. Job Purpose The Senior Systems Engineer is a key technical leader responsible for the high-level architectural design of the full KARNO generator system’s mechanical, electrical, and fluid hardware, ensuring it satisfies customer and product requirements from concept through delivery. This role owns the translation of customer and product manager inputs into detailed technical requirements and leads the engineering and validation testing effort needed to prove the system out. Working across mechanical, electrical, thermal, and fluid systems disciplines, the Senior Systems Engineer partners closely with project management, production, and manufacturing teams to keep the product on schedule, while also providing technical mentorship to less experienced members of the engineering team, with the ability to step into hands-on design work directly when needed. This role advances KARNO’s development through disciplined systems thinking, clear requirements ownership, and strong cross-functional leadership. AI at Hyliion At Hyliion, AI is core to how we work.

Hyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production. The Company’s primary focus is to develop distributed power generators that can operate on various fuel sources to future-proof against an ever-changing energy economy. Job Purpose The Senior Supplier Quality Engineer owns the technical health of Hyliion's precision machining supply base and serves as the senior technical authority for machined content on the KARNO Power Module. Much of the machined content that determines whether a machine runs, including tolerances, surface finishes, form and runout requirements, and sealing surfaces, is produced by external partners, some of it on additively manufactured parts. This position sets the standard for how supplier quality is practiced at Hyliion, including the qualification evidence required, the inspection methods used, and the technical judgment applied when a part is borderline. The role works in both directions: outward, building engineering-grade partnership with machining suppliers and closing the gap between what drawings require and what supplier processes can repeatably deliver; and inward, holding Product Engineering, Quality, Supply Chain, and Operations accountable for releasable drawings, defined acceptance criteria, realistic schedules, and closed feedback loops. The position carries no authority over those functions and operates through technical credibility and evidence. AI at Hyliion At Hyliion, AI is core to how we work.
