Software Engineer - Backend

About 1XWe're building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it's not.To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you're inspired by this, you'll thrive here. We've been at this since 2014 and we're at the point where the hard problems are behind us and the hard work is in front of us.NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We're not demoing it - we're shipping it. We're excited to meet you, if this excites you.If you've spent your career working on problems that matter and want to see them actually reach the world - this is that moment. We're scaling, we're hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.Your CharterOwn the design and execution of all software connecting the physical and digital layers of 1X's global robot operations from fleet management and real-time control to customer interfaces and internal operations platforms. This is critical-path work: as 1X scales from hundreds to tens of thousands of robots, the reliability, performance, and simplicity of this layer determines whether the business can operate, whether customers can trust their deployments, and whether the engineering team can move fast. You will lead architecture decisions, build core components, and set the technical standard for the team.Key OutcomesDesign and ship scalable backend systems that support real-time robot control, data pipelines, and fleet monitoring as 1X scales from hundreds to tens of thousands of deployed robotsOwn and deliver customer-facing applications for robot control, monitoring, and management that set a high bar for reliability and user trustBuild internal platforms that support logistics, manufacturing, and service operations; turning raw operational data into tools the business can act onSet technical direction, establish reliability and performance standards, and raise the bar for the engineering team through code review, mentorship, and high-leverage architectural decisionsKey CompetenciesSystems architect who designs for scale from the start thinking through distributed failure modes, data consistency, and performance constraints before writing a line of code, and builds systems that stay simple as they growExecution-focused builder taking end-to-end ownership, ships production systems, and resolves high-impact issues without waiting for direction; relentlessly focused on simplicity and scalabilityTechnical leader setting direction, reviews critical code, mentors engineers, and makes data-driven decisions that improve outcomes across the teamComfortable at the hardware-software boundary understanding the constraints of real-time systems, IoT, or robotics and designs cloud infrastructure that accommodates them without overcomplicating itMinimum Requirements10+ years of software engineering experience, with 3+ years leading teams that ship production systemsDeep expertise in distributed systems, cloud architecture (AWS or GCP), APIs, and real-time data pipelinesProficiency in Python, Go, or C++, with a proven track record of designing systems that scale while maintaining performance and stabilityPreferred SkillsExperience in robotics, IoT, or real-time control systems where software interfaces with physical hardware at scaleFamiliarity with fleet management, OTA deployment, or device telemetry systemsExperience hiring and growing engineering teams in a fast-moving environmentWhat Does a Successful 1X Team Member Look LikeTeam members at 1X who thrive here are builders. They move fast, own their work completely, and treat time like it's the one thing you can't get back - because it is. They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask. We push each other to be better, and we do it with honesty and respect.Compensation Range$180,000 – $280,000 + EquityBenefitsComprehensive medical, dental, and vision coverageGenerous paid time off, company holidays, and parental leave401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) optionsCommuter benefits (transit and parking)Short-term and long-term disability, and life insuranceEmployee Assistance Program (EAP) for mental health, financial, and personal supportOnsite snacks and catered lunchesEqual Opportunity Employer1X is an Equal Opportunity Employer.
