Full Stack Engineer

About Conntour

Conntour is a fast-growing defense-tech startup backed by top-tier Silicon Valley investors, including Y Combinator, General Catalyst, and SV Angel.

We’re building an AI video intelligence platform that transforms how government, intelligence, and security organizations interact with video. Using natural language, our platform enables real-time threat detection and rapid investigations across thousands of cameras.

Our technology is already deployed with leading government and security agencies worldwide, and we’re now scaling our product, team, and global operations.

As a Full Stack Engineer at Conntour, you’ll play a key role in shaping both our product and engineering foundations. You’ll own critical features end-to-end, build intuitive interfaces for complex AI-powered workflows, and help define the architecture and technical direction of a platform already used in mission-critical environments. This is a hands-on opportunity to build sophisticated technology, solve challenging engineering problems, and see your work make a real impact.

As a Backend Engineer at Conntour, you’ll be one of the first engineers shaping the foundation of our platform.

You’ll design and build high-scale, performance-critical backend systems that power real-time video and AI-driven workflows in high-stakes environments. Your work will directly influence our architecture, infrastructure, deployment strategy, and engineering standards from the ground up.

This is a hands-on role for someone who loves building robust systems, optimizing performance, owning infrastructure, and solving hard problems where reliability and speed matter.

• Lead critical projects end-to-end, from design to deployment, across our stack.
• Own system architecture and make foundational decisions that balance speed, scalability, and stability.
• Translate complex data and ML outputs into intuitive, reliable user experiences.
• Ensure production-readiness, observability, and deployment excellence from day one.
• Mentor engineers, set technical standards, and help shape our engineering team and processes.
• Collaborate closely with design, product, and ML teams to deliver seamless, mission-critical experiences.

• 3-5 years of Full Stack engineering experience.
• Strong skills in React, TypeScript, and modern front-end best practices.
• Backend experience with Python (FastAPI) and PostgreSQL (or similar stacks), plus architectural thinking and system design at scale.
• Computer Science degree.
• Comfortable using AI-powered development tools to accelerate engineering workflows while maintaining high code quality.
• Thoughtful and fast-moving, with a proactive, accountable, product-oriented mindset and a bias for action.
• Passionate about building technology with real-world consequences.

• Experience with LLMs, Computer Vision, vector databases, or AI agents.
• Production experience with Docker, Kubernetes, and modern deployment pipelines.
• Background in deploying and managing on-premises solutions.
• Prior startup or 0→1 team-building experience.

• Advanced AI technology: Work with real-time computer vision, multimodal AI, large-scale video systems, and intuitive user interfaces.
• Real-world impact: Build technology already used by leading government and security organizations to protect people and critical infrastructure.
• Ownership from day one: Take meaningful responsibility for product development, technical decisions, and engineering standards.
• Hard problems, real users: Build sophisticated systems that must perform reliably in demanding, high-stakes environments.
• Early-stage opportunity: Join a growing team with proven technology, global customers, and ambitious plans for expansion.

We move fast, care deeply, and are looking for teammates who do the same. Join us. Let’s build something that matters.
