About the Role
A seed-stage SaaS company serving hardware engineers in complex, regulated industries — including aerospace and defense — is hiring a Senior Software Engineer to own core systems in an AI-assisted cloud platform. This is a high-ownership, product-focused role at a small, early team where your architectural decisions will directly shape the product's technical foundation. You'll work across high-performance diagramming, real-time collaboration, and physics-based simulation in an environment that moves fast and builds for demanding customers.
What You'll Do
-
Architect application infrastructure spanning the cloud ecosystem, AI copilot, and physics simulation backend.
-
Lead development of major features end to end — from architecture and implementation through deployment and sustainment.
-
Collaborate closely with the product team to identify and deliver capabilities that customers need.
-
Define and champion technical standards and long-term system architecture as the product and team scale.
What We're Looking For
Required
-
5+ years of experience as a software engineer with demonstrated ownership of production systems or large-scale features.
-
Deep expertise in at least one layer of the stack — such as frontend frameworks, real-time collaboration, or AI/ML systems.
-
Proficiency with modern tooling: React, TypeScript, and Python.
-
Strong product intuition and proven ability to collaborate across disciplines in a fast-paced environment.
-
Experience with physics-based modeling and simulation systems.
-
Ability and willingness to work on-site in New York, NY (this is not a remote role).
-
Must be eligible to work in the United States without visa sponsorship.
Nice to Have
-
Background in hardware engineering tooling, CAD systems, or regulated industries (e.g., aerospace, defense).
-
Experience building or contributing to real-time collaborative applications.
-
Familiarity with cloud infrastructure design and deployment at scale.
Compensation & Benefits
-
Salary: $120,000 – $170,000 per year, depending on experience.
-
Early-stage equity opportunity.
-
Small team with high individual impact and room to grow as the company scales.
Location
-
On-site: New York, NY — in-person presence is required.
-
Remote work is not available for this position.
-
Visa sponsorship is not available; candidates must be authorized to work in the US without sponsorship.
