Our end-to-end technology stack helps app marketers acquire and retain high-value users, while enabling publishers to maximize revenue across programmatic and direct demand.\nLiftoff’s solutions, including Accelerate, Direct, Monetize, Intelligence, and Vungle Exchange, support over 6,600 mobile businesses across 74 countries in sectors such as gaming, social, finance, ecommerce, and entertainment. Founded in 2012 and headquartered in Redwood City, CA, Liftoff has a diverse, global presence.\nJoin Liftoff as a Senior Gen AI Software Engineer and help shape the future of ad tech. As a key member of our Gen AI team, you’ll design and build AI-powered products for our demand-side business, helping teams turn complex data into better decisions and meaningful customer growth.\nYou’ll work across the stack, building intelligent systems and data pipelines in Python, alongside the TypeScript and React experiences that bring those capabilities to users. You’ll partner closely with product, engineering, and customer-facing teams to identify high-impact opportunities, move quickly from prototype to production, and continuously improve what you ship.\nThis is a hands-on role for an engineer who enjoys working at the intersection of AI, product, and software engineering. You’ll help define how Liftoff applies modern AI to real business problems, balancing experimentation with the judgment and engineering discipline needed to build useful, reliable products.\nThis role is ideal for an engineer who thrives in ambiguity, enjoys experimenting with new technology, and is motivated by turning promising AI capabilities into products that create real value. You’ll tackle complex problems, validate new approaches, and drive meaningful improvements across Liftoff.\nWHAT YOU'LL DO\nOwn generative AI product capabilities end to end, from understanding user workflows and prototyping an approach through implementation, rollout, measurement, and ongoing improvement.\nRapidly prototype and validate AI solutions, using focused experiments to test user value and technical feasibility, then turn what works into production-ready capabilities.\nBuild agentic workflows that can reason over campaign, customer, creative, and performance data, use well-defined tools, produce structured results, and hand control back to a person when appropriate.\nPartner closely with decision makers and subject matter experts to understand their workflows, constraints, and business context, then integrate AI agents into daily work in practical and useful ways.\nDesign how AI systems access and use relevant information, including the data, tools, and instructions needed to produce useful grounded results.\nBuild the systems that make AI workflows reliable in production, including tool use, state management, failure recovery, and appropriate boundaries for human review.\nDefine clear, testable interfaces between models and software so uncertain model behavior can be handled safely within dependable product systems.\nDevelop evaluation systems that measure whether AI features accomplish the intended task, using realistic examples and an appropriate combination of automated checks and human judgment.\nBuild the instrumentation needed to understand quality, adoption, business impact, latency, cost, and failure modes in production.\nApply appropriate safeguards for customer data, system access, and high-impact workflows.\nBuild the Python services and TypeScript and React interfaces that turn these capabilities into cohesive products for customer facing teams.\nEvaluate new models and techniques pragmatically, adopting them when they materially improve product quality, capability, speed, or cost.\nMentor other engineers and help establish shared practices for designing, testing, and operating AI-powered products.\nWHO YOU ARE\nMinimum Bachelors Degree and 8 yrs of relevant experience.\nYou are a seasoned software engineer who has built and operated meaningful production products, ideally including zero-to-one work spanning backend services, data, and user interfaces.\nYou have shipped LLM-powered or AI-assisted products beyond a demo and understand the practical challenges of reliability, context, tool use, provider changes, latency, cost, and changing model behavior.\nYou are highly proficient in Python and comfortable working in TypeScript and React, with strong fundamentals in API design, data modeling, SQL, and testing.\nYou understand how to build the broader system around a model, including its data, tools, instructions, permissions, feedback loops, and measures of quality.\nYou can define success criteria, investigate failures, and use testing, feedback, and production signals to improve AI experiences over time.\nYou exercise strong product and engineering judgment, choosing when a problem calls for traditional software, an LLM-powered approach, or a thoughtful combination of both.\nYou communicate complex technical ideas clearly and collaborate effectively with domain experts and non-technical partners.\nYou are comfortable working through ambiguity, making informed decisions with incomplete information, and changing direction when evidence shows a better path.\nYou are a lifelong learner with strong but flexible opinions, and you thrive on giving and receiving constructive feedback.\nHelpful, but not required\nExperience as an early engineer, startup founder, or in a similarly high-ownership environment where you moved quickly from ambiguous problems to shipped products.\nExperience with advertising technology, campaign optimization, performance marketing, analytics products, or other data-rich B2B software.\nLocation:\nThe preferred location for the role is in Pacific Standard Time Zone. This role is eligible for full-time remote work in one of our entities: CA, CO, ID, IL, FL, GA, MA, MI, MN, MO, NJ, NV, NY, OR, PA, TX, UT, and WA.\nWe are a remote-first company with US hubs in Redwood City, Los Angeles, and New York City.\nTravel Expectations:\nWe offer several opportunities for in-person team gatherings, including but not limited to project meetings, regional meetups, and company-wide events.
