[Hiring] Full Stack Engineer @NetSpeek

Role Description

The Full Stack Engineer ships features end-to-end across the .NET backbone, the React surfaces, and the operator workflows on top of Lena. You'll move across the stack daily.

• Designing and shipping .NET 6+ backend services that mediate between AI reasoning, device adapters, and operator surfaces.
• Building React surfaces that present Lena's signal — including uncertainty shape, not just confidence numbers.
• Owning the REST API design between backend and frontend (and Lena's Python services).
• Driving operator UX decisions in partnership with product, with attention to the workflows operators run dozens of times a day.

Qualifications

• 5+ years of .NET / C# backend experience, with hands-on production work in .NET 6 or newer.
• 3+ years of React (or comparable modern framework) experience.
• Shipped end-to-end features that touched both backend and frontend in the same project.
• Designed and shipped production REST APIs in a distributed SaaS environment.
• Hands-on production experience with AWS (preferred), Azure, or GCP.

Requirements

• Strong backend engineering experience in .NET / C#, with hands-on production work in modern .NET (6+, not legacy Framework only).
• Frontend development experience with modern React (or comparable framework such as Next.js, Vue, or Svelte).
• API design experience for distributed SaaS systems; designed and shipped production REST APIs.
• Cloud-native application development with AWS preferred (Azure or GCP also welcome).
• Strong debugging and systems thinking.

Benefits

• Flexible / unlimited time off.
• Health insurance.
• Equity participation, discussed at offer.
• Fully remote.
• Architectural ownership of work that ships to real enterprise customers.
• Direct working relationships with the people setting platform strategy.
• A growth-stage platform where the decisions you make in your first year shape the product for years.
• AI-assisted tooling licensed by NetSpeek (Cursor, Claude Code, GitHub Copilot, or comparable).
