Principal Software Engineer

At MegaCool Technologies, we aren't just making parts; we are solving the most physical bottleneck in the AI revolution: Heat .

While traditional data center cooling is reaching its physical limits, we’ve developed ultra-performant Smartfins technology using proprietary generative algorithms.

We are a lean, fast-moving startup bridging the gap between high-level software intelligence and massive-scale hardware manufacturing.

If you want to see your code manifest as physical hardware deployed at a global scale, you belong here.

The Role

As our Principal Software Engineer, you will lead the design and development of our digital backbone from scratch.

This is a high-autonomy, high-impact role where you define the "how" and the "why" of our technical architecture.

You are a methodical problem-solver who thrives in a design-driven, rapid-iteration environment.

Your mission is to translate "impossible" thermal problems into a secure, scalable, and maintainable SaaS platform that handles complex data interactions at the speed of the GPU refresh cycle.

Key Responsibilities

• Shape Technical Architecture
  Own the blueprint. Define, communicate, and guide architectural decisions to ensure our platform is resilient, fault-tolerant, and future-proof.
• Ship with Velocity
  Find the path to get things done despite roadblocks. You will deliver high-quality, well-tested, and secure code into the hands of users quickly and iteratively.
• Elevate Engineering Standards
  Champion clean code and robust testing frameworks. You don't just write code; you set the "gold standard" for the entire engineering culture.
• Own the DFM Loop
  Work at the intersection of software and physics, collaborating with mechanical engineers to integrate our "Smartfins" logic into a seamless cloud experience.
• Automate & Scale
  Implement DevOps best practices, including CI/CD pipelines and orchestration tools, to enhance the deployment of our solutions.
• Leverage Next-Gen Tools
  Accelerate the development lifecycle by expertly using AI-assisted tools (Gemini, Claude, GitHub Copilot) for code generation, debugging, and unit testing.

What You Bring

The Essentials

• A Master’s Degree in Computer Science or a related technical field (or equivalent "battle-tested" experience).
• 7+ Years of Engineering Excellence: A proven track record of building large-scale, customer-facing SaaS applications in fast-paced environments (Deep-Tech, Fintech, or High-Growth Startups).
• Full-Stack Sovereignty: Deep proficiency in modern languages (Python, Go, C#, or Java) and a methodical approach to complex data systems.
• Cloud Native Expertise: Experience securing and scaling applications on Azure, AWS, or GCP.
• Founding Grit: You are adaptable and resilient. You excel at navigating shifting priorities and ensuring high-impact deliverables stay on track without "red tape."

The "Extra Mile"

• Background in the semiconductor, data center, or AI infrastructure sectors.
• The desire to eventually grow and mentor a world-class engineering team.
