Co-Founder & Chief Technology Officer (CTO)
Position Type: Co-Founder / Full-Time
Location: Norway
Start Date: Immediate / Q1 2026
Equity: [To Be Discussed - Co-Founder Level]
COMPANY OVERVIEW
SemantiSys is an AI-powered AR platform revolutionizing aerospace engine maintenance (MRO). We eliminate information bottlenecks that cost the industry billions annually by providing technicians with real-time, context-aware guidance through AR interfaces. Our solution validates every step of complex maintenance procedures, reducing errors, downtime, and costs while ensuring regulatory compliance.
We are pre-revenue with active pilot programs and are seeking a technical co-founder who can build, ship, and scale our product from pilot to enterprise-grade SaaS platform.
THE ROLE
We are seeking a Co-Founder & CTO who will be the technical leader responsible for architecting, building, and scaling our AI-powered AR platform. This is not a research role - you will be building production software that ships to customers. You will work alongside the founder/CEO to define technical strategy, make critical architecture decisions, and lead the engineering team as we grow.
This is a co-founder position with equity and the opportunity to shape the company's technical direction from the ground up.
KEY RESPONSIBILITIES
- Technical Leadership & Architecture (40%)
- Architect scalable, enterprise-grade SaaS platform for aviation MRO
- Make critical technology stack decisions (Python, cloud infrastructure, AR/XR integration)
- Design multi-tenant architecture with security and compliance built-in
- Establish development practices, code quality standards, and technical culture
- Balance technical perfection with startup speed and resource constraints
- AI/ML Development & Integration (30%)
- Build production-ready AI/ML systems (not just prototypes or research)
- Integrate LLMs, multi-modal agents, and computer vision into product
- Develop contextual validation and guidance systems
- Optimize models for production (latency, accuracy, cost)
- Implement AI governance, explainability, and safety guardrails
- Product Development & Shipping (20%)
- Lead development of core product features and AR interfaces
- Ship production software on aggressive timelines
- Iterate quickly based on pilot feedback and customer needs
- Build APIs, integrations, and developer tools
- Ensure product quality, reliability, and user experience
- Team Building & Leadership (10%)
- Hire and lead engineering team as company scales
- Mentor developers and establish technical best practices
- Build diverse, high-performing engineering culture
- Collaborate with CEO on technical strategy and product roadmap
REQUIRED QUALIFICATIONS
- Strong Python Portfolio
- Demonstrable Python production code (GitHub, portfolio, code samples)
- Experience building production Python applications (not just Jupyter notebooks)
- Understanding of Python best practices, testing, and code quality
- Experience with Python frameworks (FastAPI, Flask, Django, or similar)
- Production Software Development Experience
- 5+ years building and shipping production software products
- Experience with scalable, multi-tenant SaaS architectures
- Understanding of cloud platforms (AWS, Azure, or GCP)
- Experience with APIs, microservices, and distributed systems
- DevOps, CI/CD, monitoring, and production operations
- AI/ML Hands-On Experience
- Practical experience building AI/ML systems in production (not just research)
- Experience with LLMs, NLP, computer vision, or multi-modal AI
- Understanding of model deployment, optimization, and production ML
- Experience with ML frameworks (TensorFlow, PyTorch, or similar)
- Ability to translate AI research into production code
- Startup/Product Mindset
- Experience in startups or fast-paced product environments
- Comfortable with uncertainty, rapid iteration, and resource constraints
- Ability to balance perfection with speed (ship fast, iterate)
- Product-focused (build what customers need, not what's technically perfect)
- Comfortable wearing multiple hats and doing hands-on development
- Technical Leadership
- Experience leading engineering teams or technical projects
- Ability to make critical architecture decisions
- Strong communication skills (technical and non-technical audiences)
- Ability to mentor developers and build technical culture
NICE TO HAVE (Preferred but Not Required):
- AR/XR development experience (Unity, OpenXR, or similar)
- Enterprise SaaS experience (B2B, compliance, security)
- Aviation/MRO domain knowledge
- Graph database experience (Neo4j)
- Compliance experience (SOC2, GDPR, EU AI Act)
- Full-stack development experience
- Experience scaling products from pilot to enterprise
WHY THIS ROLE?
- Co-Founder Equity: Equity stake as technical co-founder
- Technical Ownership: Shape technical direction from the ground up
- High Impact: Solve real problems in critical industry (aviation safety)
- Growth Opportunity: Build and lead engineering team as company scales
- Cutting-Edge Tech: Work with AI, AR, and complex domain problems
- Market Timing: Pre-revenue with pilots, ready to scale
