I'm partnering with a well-funded, mission-driven technology company building next-generation software that supports real-world security, autonomous operations, robotics, and intelligent systems.
We're seeking a Full Stack Engineer who thrives in fast-paced startup environments and enjoys solving complex technical challenges across the frontend, backend, cloud infrastructure, and real-time systems.

- Work on systems involving live data streams, video, event-driven architectures, and connected devices.
- Collaborate closely with product, operations, and end users to translate real-world requirements into software solutions.
- Improve reliability, performance, observability, security, and deployment processes.
- Leverage modern AI-assisted development tools while maintaining high standards for code quality and maintainability.
What We're Looking For
- Strong hands-on experience developing full-stack applications.
- Proficiency with modern frontend frameworks (React, TypeScript, Angular, or similar).
- Experience building backend services using technologies such as Node.js, Python, Go, Java, or C#.
- Strong understanding of cloud platforms, distributed systems, APIs, databases, and system architecture.
- Experience building and supporting production-grade applications.
- Comfortable operating in a startup environment with high ownership and autonomy.
- Strong problem-solving skills and the ability to work across multiple technical domains.
Nice to Have
- Experience with real-time systems, streaming data, live video, IoT, robotics, autonomous platforms, aerospace, defense, security technology, geospatial applications, or AI/ML-enabled products.
- Experience building software that integrates with hardware or edge devices.
- Exposure to highly secure or compliance-driven environments.
Why Join?
- Build greenfield technology with significant influence on product direction
- Work on software with tangible real-world impact
- High ownership and visibility from day one
- Modern engineering culture leveraging AI-assisted development
- Backed by experienced leaders from high-growth technology organizations
- Equity package offering meaningful upside
If you're interested in solving challenging technical problems and building innovative software at the intersection of cloud, real-time systems, and emerging technology, I'd love to connect.
