Delta Engineer

We are an applied AI lab building end-to-end software agents.We're the makers of Devin, the first AI software engineer, and Windsurf, the AI-native IDE. Together, they represent our vision for collaborative AI teammates that enable engineers to focus on more interesting problems and empower teams to strive for more ambitious goals.Our team is small and talent-dense. Among our founding team, we have world-class competitive programmers, former founders, and leaders from companies at the cutting edge of AI including Scale AI, Palantir, Cursor, Waymo, Tesla, Lunchclub, Modal, Google DeepMind, and Nuro.Building Devin and Windsurf is just the first step—our hardest challenges still lie ahead. If you’re excited to solve some of the world’s biggest problems and build AI that can reason on real-world tasks, apply to join us.About the RoleDelta Engineers bring technical depth to Cognition’s most complex enterprise engagements.You'll own the technical direction of a focused set of high-impact accounts, tackling the hardest problems that shape long-term adoption, architecture, and how the Cognition platform evolves. This means architecting deployments, building integrations, and debugging what no one else can figure out.A core part of this role is shaping the product. You'll identify patterns from the field, build on the product edge to unblock customers, and translate those learnings into requirements that inform what core engineering builds next. When customers hit friction that the product doesn’t solve, you’re the person who figures out what should exist—and makes it happen.Core ResponsibilitiesOperate across strategic accounts, providing technical depth on complex engagementsOwn the technical direction and success of customer accounts and deploymentsTranslate customer pain points into product direction: scope requirements, define solutions, and drive implementationBuild product extensions and integrations using Cognition’s APIs and platform primitivesArchitect and maintain complex enterprise deploymentsHandle escalated technical issues requiring deep debugging or architectural judgmentBe a credible technical voice to engineering on what the field needsWhat We ValueTechnical depth and the judgment that comes from seeing many deploymentsProduct instinct — you synthesize feedback into solutions, not just feature requestsBuilder mentality — you’d rather ship something than wait for someone else to build itCredibility with engineering teams, both internal and customer-sideComfort operating across many contexts simultaneouslyRequirementsStrong engineering foundationHave operated cross-functionally—whether at a startup wearing multiple hats or by driving product/commercial thinking at a larger companyHave a track record of pursuing excellence at high levels, in any domainProficiency in Python, TypeScript, or similar; comfort navigating unfamiliar codebasesExperience scoping and shipping features in collaboration with product and engineering teamsYou might excel if….Have built software at companies known for engineering rigor and want broader impactTrack record in forward-deployed engineering, solutions architecture, or similar technical rolesExperience with enterprise infrastructure (cloud deployments, networking, security)Want to stay close to customers while shaping how the product evolvesEnjoy hard problems without obvious solutions and the autonomy to figure them outHave a high tolerance for ambiguity, intensity, and sustained effort when the problem demands it
