Senior Engineering Manager, Builder Tools (Los Angeles)

Hadrian - Manufacturing the FutureHadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts.We’re accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts.Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond.The RoleEngineering velocity is a strategic advantage at Hadrian. As we scale our software organization, the quality of our tools, workflows, and development practices directly determines how fast we can move. The Builder Tools team owns that surface area, working across the entire SDLC to reduce friction, accelerate delivery, and bring AI-assisted development practices to every engineering team.As Senior Engineering Manager of Builder Tools, you will lead a team of 6-10 engineers focused on engineering productivity, internal tooling, and AI-enabled development workflows. Your users are Hadrian's engineers, and your mission is to make them faster and more effective. You will report to the VP of Engineering and partner closely with infrastructure, security, and product teams to drive improvements across CI/CD, testing, deployment, and observability.This is a high-leverage role. The work you ship here touches every engineer at Hadrian.What You'll DoLead and grow a team of engineers focused on engineering productivity and internal developer toolsDefine and execute a roadmap to improve end-to-end SDLC efficiency and reliability (plan, build, test, deploy, observe)Drive adoption of AI-assisted development tools across engineering, from code assistants to LLM-powered workflowsIdentify bottlenecks in developer workflows and implement scalable, lasting solutionsImprove CI/CD systems, testing frameworks, and deployment processesEstablish metrics to measure developer productivity and system performancePartner with infrastructure, security, and product teams to improve delivery pipelinesHire, mentor, and develop engineers and tech leadsEnsure high standards for reliability, scalability, and maintainability across internal toolingWhat We're Looking For8-12 years in software engineering, with 3-5+ years in engineering managementStrong backend or platform engineering background with deep familiarity with modern SDLC systemsExperience leading and scaling high-performing engineering teamsTrack record of delivering measurable improvements in engineering velocity or system reliabilityAbility to think in systems: understand the end-to-end development lifecycle and identify where to optimizeExperience with CI/CD tooling (GitHub Actions, Buildkite, or similar), observability stacks (Datadog, Prometheus), and cloud infrastructure (AWS/GCP, Kubernetes)Bachelor's degree in Computer Science or related field, or equivalent experienceWhat Will Set You ApartHands-on experience implementing AI-assisted development workflowsFamiliarity with LLM APIs (OpenAI, Anthropic, etc.) and AI coding tools (Copilot, Cursor, etc.)Experience with CI/CD optimization at scaleStrong data-driven approach to measuring and improving developer productivityAbility to treat internal tooling as a product: clear users, defined impact, feedback loopsExperience driving adoption of new tools and workflows across engineering organizationsGrowth & TrajectoryThis role is a high-leverage position with significant room to grow.
