Lead Software Engineer, Factory Core

Hadrian - Manufacturing the Future Hadrian 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 Role: As a Lead Fullstack Engineer, you will own a major domain within Flow and drive outcomes across multiple teams and factory sites. We have a broad set of internal applications, with significant opportunities to redefine manufacturing software. No aerospace, defense, or manufacturing background required. Flow is Hadrian's FactoryOS: a distributed, mission-critical software platform that coordinates how work is planned, executed, measured, and improved across many factories. Flow is an interconnected platform of services, applications, data pipelines, and operational workflows that must evolve quickly without sacrificing reliability. The scope of this role is product engineering leadership at organizational scale: shaping architecture and execution across multiple teams while maintaining high standards for quality, security, observability, and delivery. What You’ll Do Own and lead a major Flow domain end-to-end, from strategy and architecture through delivery, rollout, and long-term operation. Architect distributed systems that operate reliably across many factories, balancing latency, resilience, data consistency, observability, and operational complexity. Scope, architect, implement, and deploy critical full-stack applications that drive revenue and factory throughput. Set technical direction for a product vertical, define roadmaps with stakeholders, and align engineering execution to measurable business outcomes. Partner with internal and external customers, operators, and factory leadership to turn ambiguous problems into clear plans and shipped solutions. Lead cross-team architecture and execution: clarify dependencies, sequence work, manage risk, and keep delivery momentum across shared systems. Establish durable engineering practices across teams, including testing strategy, operational readiness, observability standards, and incident response playbooks. Build and mentor senior engineers, raise review quality, and improve team execution through strong technical leadership. Translate business priorities into technical plans and milestones, then drive delivery with clear ownership, sequencing, and accountability. What We’re Looking For Proven lead-level ownership of product domains and business-critical systems at scale, including technical strategy, prioritization, and sustained operational responsibility. Strong experience building and evolving distributed systems in production, ideally across multiple sites, environments, or regions. Excellent problem-solving skills: break down ambiguous, high-impact problems, navigate trade-offs, and make pragmatic decisions under constraints. Exceptional communication and influence: align engineers, operators, and leadership; facilitate decisions; and keep stakeholders informed with clarity and precision. Track record of leading critical initiatives across several teams and shipping high-quality outcomes in large, complex codebases. Strong systems thinking: understand how services, data flows, and team boundaries interact, and use that understanding to prevent bottlenecks and future scaling issues. Demonstrated ability to improve engineering effectiveness through better architecture, process, documentation, and mentoring. Extensive experience shipping modern, full-stack applications (our front-ends are React/Typescript and back-ends are Go). Product-minded and user-driven, with a bias to action and a focus on getting to the right solution rather than being right. Excited to work in a fast-paced environment with high-stakes and quick iteration cycles. Compensation For this role, the target salary range is $200,000 - $270,000 (actual range may vary based on experience). This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future. An employee's pay position within the salary range will be based on several factors, including, but not limited to, relevant education, qualifications, certifications, experience, skills, geographic location, performance, and business or organizational needs. Benefits for Full-time Employees Medical, dental, vision, and life insurance plans for employees 401k Relocation support may be provided for certain situations, based on business need.
