N43 Studio is a venture studio dedicated to building bold, technology-driven companies from the ground up. We identify emerging opportunities, develop ideas into working prototypes, and launch ventures designed to scale.
At N43 Studio, we don’t wait for disruption—we create it. Our team of founders, technologists, and operators turns insight into impact by testing real-world problems, validating solutions fast, and launching startups that matter.
With a deep focus on sectors where innovation can unlock lasting value, we’re building the future one venture at a time. Whether it’s AI-powered tools, novel platforms, or entirely new business models, our companies are built for the world ahead.
About The Role
We’re hiring an AI Engineer to lead the development of intelligent systems across our ventures. You’ll design, prototype, and deploy AI-powered features—from LLM-driven experiences to predictive analytics. You’ll also be responsible for exploring and applying small language models (SLMs) that can run efficiently within our products, ensuring we balance cutting-edge capabilities with speed, cost, and scalability.
What You’ll Do
- Prototype and productionize AI-powered features using modern ML/AI frameworks.
- Integrate large language models (LLMs) from providers such as OpenAI and Anthropic, as well as open-source models from Meta and others (e.g., LLaMA, Mistral, Falcon).
- Explore and implement small language models (SLMs) to create efficient, product-embedded AI solutions.
- Build pipelines for fine-tuning, prompt engineering, and evaluation.
- Work with structured and unstructured datasets to extract insights and power features.
- Collaborate with product and design to shape user-facing AI interactions.
- Stay ahead of emerging trends and apply them pragmatically in ventures.
What We’re Looking For
- 4+ years of experience in applied ML or AI engineering.
- Strong Python skills and familiarity with ML frameworks (PyTorch, TensorFlow, HuggingFace).
- Experience working with large language models and generative AI.
- Familiarity with small/edge language models and strategies for efficient deployment.
- Knowledge of vector databases, embeddings, and retrieval-augmented generation (RAG).
- Ability to take projects from prototype to production in a lean environment.
- A passion for solving real-world problems with AI.
Bonus
- Experience in early-stage startups or venture studios.
- Background in data engineering, NLP, or computer vision.
- Contributions to open-source AI/ML projects.
Why Join Us
- Work at the frontier of AI applications across multiple ventures.
- Explore both large and small language models to build the right AI solutions for each product.
- Build products where AI is not just a feature but the core value driver.
- Flexible, hybrid work based out of our studio HQ in downtown Toronto.
Artificial intelligence (AI) tools may be used to support certain stages of the recruitment process, including application review, resume analysis, and response assessment. These tools are intended to assist our hiring team and do not replace human judgment. Final employment decisions are made by human reviewers.

What We Do
We build enduring ventures at the intersection of innovation and execution.
Too often, startups are launched in isolation — chasing hype, disconnected from real customers, and overly reliant on funding to validate ideas. At N43 Studio, we take a different approach. We pair entrepreneurial builders with real-world opportunities sourced from deep market insight, industry access, and our enterprise partners. Then we bring the tools, team, and infrastructure needed to go from zero to one — faster, smarter, and with intention.
Why Work With Us
N43 is for builders who want impact at speed. You get autonomy to ship zero-to-one products, plus a studio behind you—design, product, talent, and GTM—so you focus on what’s truly hard. It’s senior, low-ego teams, rapid learning across multiple ventures, and real ownership in what you create.
