Principal Engineer

5V Tech

About the company

Salary: Competitive (DOE)

This company builds autonomous AI software for industrial enterprises, combining reinforcement learning, machine learning, optimization and modern cloud software engineering to move customers from AI pilots to production at enterprise scale.

About the role

This is a genuinely hands-on role, not a traditional VP or Head of Engineering position sitting above the work. The company already has a clear founder-led product vision and an AI-native development methodology producing strong results, so this hire won't be redefining strategy or building out a large org. We're recruiting an engineering leader who still writes and reviews Python code daily, stays close to architecture and technical decisions, and wants to turn an ambitious technical vision into production-grade software used by the world's largest industrial companies. You'll execute an established product roadmap in partnership with the Founder/CPO and CEO, remain deeply embedded in the codebase, and maximize engineering leverage through AI before adding headcount.

Key responsibilities

Stay hands-on in the codebase, writing and reviewing Python daily alongside the team
Lead a small, elite engineering team focused on exceptional execution and customer outcomes
Own software architecture, engineering quality, scalability and operational excellence
Translate product vision into high-quality production software with speed and discipline
Drive engineering best practices across CI/CD, testing, observability, cloud infrastructure and security
Partner closely with Product, R&D and Customer Success to deliver enterprise-ready capabilities
Coach engineers while fostering a low-ego, high-accountability culture of continuous learning
Embrace, improve and extend the company's AI-first software development workflow

Ideal profile

8+ years building production software, with a strong preference for hands-on coding throughout your career
3+ years leading engineering teams (preferred), without stepping away from technical execution
Deep experience with enterprise SaaS, distributed systems and cloud-native architectures
Strong background delivering AI/ML applications into production
Deep expertise designing, reviewing and shipping production Python systems (FastAPI, Flask or similar)
Experience with REST APIs, microservices and distributed systems
Experience with Docker, Kubernetes and AWS/Azure/GCP
Experience with PostgreSQL and modern data infrastructure
Experience with CI/CD, GitHub and Infrastructure as Code

Preferred qualifications

Experience working in fast-moving Seed or Series A environments
PyTorch, TensorFlow, reinforcement learning and modern AI frameworks
LLMs, agentic AI and AI-assisted software development
Commercially minded, with a passion for building category-defining Industrial AI software

APPLY NOW to discuss further details.
