Are you a builder at heart who loves solving complex technical problems and shaping scalable systems? Join our stealth-mode AI startup where you'll have high ownership and the ability to make meaningful decisions that directly impact our product and technical direction.

We're looking for a Senior Software Engineer (Full-Stack) to play a pivotal role in building reliable backend services, optimizing databases, and shaping architectural decisions. If you thrive in a fast-paced environment, love collaborating with fellow senior engineers, and take pride in writing clean, maintainable code, we'd love to meet you.

## Tasks

**What You'll Do**

*   **Build & Scale Backends:** Design, develop, and maintain backend services and APIs using Node.js, TypeScript, and PostgreSQL.
*   **Model & Optimize Databases:** Create efficient schemas to support current needs while planning for future scale.
*   **Shape Architecture:** Collaborate with other senior engineers and the CTO to refine system design and ensure smooth integration between backend, frontend, and infrastructure.
*   **Validate Infrastructure:** Partner with our DevOps team to review and validate AWS configurations, deployments, and security practices.
*   **Enhance CI/CD:** Ensure robust, automated pipelines for reliable deployments and rapid iteration.
*   **Maintain Quality:** Write clean, testable, and scalable code and participate in code reviews to uphold engineering best practices.
*   **Mentor & Share Knowledge:** Support junior engineers through guidance, debugging help, and sharing best practices.
*   **Leverage AI Thoughtfully**: Use AI tools strategically to enhance productivity and code quality, with a clear understanding of when and how to apply them effectively—we don't "vibe code," we use AI to make our work better.

**What Success Looks Like**

*   High-quality, performant backend code shipped consistently with significant ownership of features and technical decisions.
*   Reliable integrations across backend, frontend, and infrastructure.
*   Valuable contributions to architecture and database design discussions.
*   CI/CD pipelines running smoothly with minimal downtime.
*   Positive peer feedback on collaboration and technical leadership.
*   Thoughtful application of AI tools that demonstrably improves development velocity and code quality.

## Requirements

**Must-Haves**

*   Strong skills in Node.js, TypeScript, and PostgreSQL.
*   Experience building and maintaining REST APIs or microservices.
*   Familiarity with AWS services (EC2, RDS, S3, IAM, etc.).
*   Solid understanding of CI/CD workflows and Git-based development.
*   Strong problem-solving and debugging skills.
*   Ability to thrive in a fast-paced, collaborative startup environment with high autonomy.
*   AI-first mindset: Comfortable using AI tools strategically while maintaining strong engineering fundamentals.

**Nice-to-Haves**

*   Experience with NestJS or similar backend frameworks.
*   Exposure to frontend frameworks like Angular.
*   Knowledge of Docker, Kubernetes, or infrastructure-as-code (Terraform, CloudFormation).
*   Performance tuning and security optimization experience.Previous experience in AI/ML startups or working with AI-powered products.

**Tools & Technologies**

*   **Core Stack:** Node.js, TypeScript, PostgreSQL
*   **Infrastructure:** AWS, Docker, GitHub Actions (or similar CI/CD)
*   **Version Control:** Git
*   **Frontend (optional):** AngularAI Tools: Integrated strategically throughout our development workflow

## Benefits

**Why You'll Love Working Here**

*   **High Ownership & Impact:** Make meaningful technical decisions and see your code power critical features from day one.
*   **Stealth-Mode Innovation:** Help build something groundbreaking in the AI space with the freedom to shape both product and architecture.
*   **Cutting-Edge Stack:** Modern tools, AI-first culture, and continuous learning opportunities.
*   **Collaborative Environment:** Work directly with other senior engineers, the CTO, and cross-functional teams who love solving complex problems together.
*   **Strategic AI Integration:** Be part of a team that uses AI thoughtfully to enhance engineering productivity, not as a replacement for solid engineering practices.
