About Linero
Linero is building the operational infrastructure that ensures the world's most sensitive technologies reach the right hands, and never the wrong ones.
Our customers include some of the most consequential companies in the world: leading AI labs, aerospace and defense primes, semiconductor giants, quantum computing pioneers, and companies pushing the frontier in chemicals, advanced manufacturing, and robotics.
We are an AI-native, venture-backed company creating a new category of software at the intersection of national security, industrial infrastructure, and enterprise AI.
The Role
As a Senior Engineer, Backend, you will own significant pieces of the core infrastructure: designing and shipping systems that power deep enterprise integrations, complex data workflows, and a product that operates under the most stringent security requirements in the industry.
This is a high-ownership role. You will drive significant architectural decisions, influence platform choices that will shape how Linero scales, and work closely with the founding engineering team to shape the architecture and trajectory of the product.
What You'll Own
Design, build, and maintain core backend services and APIs that power Linero's platform at scale
Contribute to the design and implementation of multi-tenant architecture with strict data isolation requirements
Build scalable, high-performance data pipelines that operate reliably under demanding latency and volume requirements
Collaborate closely with AI/ML, infrastructure, and frontend teams to ship cohesive, production-grade product
Establish backend engineering standards: code quality, testing practices, and deployment patterns that the team can build on
Participate in code reviews, architectural discussions, and the continuous raising of engineering standards across the team
What we're looking for
5+ years of backend engineering experience with a proven track record of designing and shipping complex, high-scale systems
Demonstrated experience with software architecture; you have designed systems, not just built to spec, and you can articulate the trade-offs behind your decisions
Deep proficiency in at least one backend language: Python, Go, or Java preferred
Strong experience with API design, distributed systems, and data modeling, including multi-tenant SaaS architectures with strict data isolation requirements
Experience building enterprise integrations across heterogeneous systems - ERPs, SaaS platforms, or internal tooling - with fluency in enterprise integration patterns
Familiarity with zero-trust security models and experience operating in high-security or regulated environments
You take ownership seriously; you don't wait to be told what needs fixing
Based in or willing to relocate to New York City
What we offer
Competitive compensation commensurate with experience
Meaningful equity in a company at an early and critical stage of growth
Comprehensive benefits including health, dental, and vision
The opportunity to shape the core architecture of one of the most consequential platforms being built today
Direct access to leadership and genuine influence over how Linero is built
