Full Stack Software Engineer (Mid–Senior) — Physical AI Fleet Platform (Python + TypeScript/JavaScript)

Cyngn • Mountain View, CA

4d • $153,000 - $171,000 • Hybrid

About The Position

Cyngn is building a cloud platform that helps customers monitor, manage, and optimize fleets of autonomous industrial vehicles in real time. As a Full Stack Engineer (Mid–Senior), you’ll ship features end-to-end—from Python backend services to TypeScript/JavaScript frontends—on a small, high-impact team. You’ll partner closely with Staff/Principal Engineers while owning meaningful parts of the product.
If you’re excited by software at the intersection of real-time systems, physical AI, digital twins, and customer-facing product, we’d love to talk.

Requirements

• 2–4+ years of professional software engineering experience.
• Strong production experience with: Python (backend services, APIs, data workflows) TypeScript or JavaScript (frontend)
• You’ve shipped and supported user-facing web applications (not just internal tools).
• You’re comfortable building APIs and working with databases (SQL preferred; NoSQL is a plus).
• You communicate clearly, take ownership, and bring a low-ego, collaborative approach.
• You care about software that’s reliable in production, not just “works locally.”

Nice To Haves

• Real-time systems experience: WebSockets, SSE, streaming updates, pub/sub.
• Event-driven systems / messaging: Kafka, RabbitMQ, Pulsar, etc.
• Experience with telemetry-heavy or operational products: IoT, robotics, autonomy, fleet/dispatch, industrial software.
• Experience building analytics features: reporting, aggregations, operational metrics, customer-facing insights.
• Familiarity with scaling patterns: caching, background jobs, rate limiting, performance tuning.
• Strong habits using AI coding assistants/agents responsibly (verification, testing, high-signal reviews).
• Exposure to physical AI simulation tooling (e.g., NVIDIA Omniverse / Isaac Sim) or similar environments.

Responsibilities

• Build customer-facing web experiences: fleet dashboards, live views/maps, alerts, admin tools, and reporting using TypeScript/JavaScript.
• Build and evolve backend services in Python that power fleet operations, integrations, data ingestion, and analytics.
• Design and implement reliable APIs (REST and/or gRPC) that are well-documented and easy to integrate with customer systems.
• Deliver real-time features (live vehicle state, events, notifications, operator workflows) using WebSockets and event-driven patterns.
• Support “physical AI” workflows by connecting cloud software to autonomy/robotics systems—telemetry pipelines, command-and-control surfaces, and operational tooling that interacts with vehicles in the real world.
• Use modern AI tools and agents to move faster and raise quality (and help build customer-facing copilot experiences where it makes sense).
• Contribute to digital-twin simulation + validation loops (where applicable): support workflows that use simulation to test behaviors, validate releases, and reproduce field issues.
• Raise engineering quality through testing, code reviews, observability, and pragmatic reliability/performance improvements.
• Own meaningful chunks of the product: shape solutions, make tradeoffs, and drive work to completion.

Benefits

• Health benefits (Medical, Dental, Vision, HSA and FSA (Health & Dependent Daycare), Employee Assistance Program, 1:1 Health Concierge)
• Life, Short-term and long-term disability insurance (Cyngn funds 100% of premiums)
• Company 401(k)
• Commuter Benefits
• Flexible vacation policy
• Remote or hybrid work opportunities
• Sabbatical leave opportunity after 5 years with the company
• Paid Parental Leave
• Daily lunches for in-office employees
• Monthly meal and tech allowances for remote employees
