About nesto and Nesto Cloud

nesto is Canada’s leading provider of mortgage technology and financing solutions, managing $73B+ CAD in residential and commercial mortgages, with 1,000+ team members across 12 offices nationwide. You will be working on Nesto Cloud, Canada’s most advanced cloud platform, delivering end-to-end technology solutions for lenders in the digital age.

Be part of a new era in software development! We’re looking for a highly analytical and innovative Prompt Engineer to join our Commercial Software team. In this role, you will be responsible for designing, testing, and implementing high-quality prompts that power AI-driven automation across our products. You are someone who’s deeply curious about language models, stays on top of the latest AI trends, and is excited to explore how prompt engineering can drive meaningful business outcomes.

What you’ll be doing

• You will create, refine, and maintain structured prompts to support automation workflows across commercial lending software.
• You will work closely with product managers, developers, and business teams to identify automation opportunities and translate them into prompt-based solutions.
• You will evaluate and test outputs across different LLMs (e.g., GPT, Claude, Gemini) and recommend the best model for specific use cases.
• You will monitor performance, analyze edge cases, and adjust prompts to improve accuracy, efficiency, and user satisfaction.
• You will contribute to the development of internal prompt libraries and versioning frameworks.
• You will stay current with emerging trends, tools, and techniques in prompt engineering and AI language models.
• You will provide clear documentation of prompt structures, use cases, and performance benchmarks.
• You will assist in training internal users on AI tooling and best practices for interacting with LLM-powered workflows.

Who we are looking for

• Two (2) years of experience in a product, data, or automation-focused role within a tech-driven environment.
• Proven experience working with LLMs (e.g., GPT-4, Claude, Gemini) and prompt engineering across business use cases.
• Deep understanding of model behavior, limitations, and use-case suitability.
• Experience monitoring prompt performance, testing variations, and implementing feedback loops.
• Proven success in contributing to a high-performance, close-knit team through proactive verbal updates and polished written correspondence that builds trust across the organization.
• Proactive and self-driven approach to work, demonstrating the ability to independently manage projects from inception to completion while consistently meeting deadlines.
• A process-oriented mindset with the ability to understand business workflows and implement practical improvements.
• Familiarity with AI/ML concepts, vector databases, and APIs will be considered an asset.
• Experience working in commercial real estate will be considered an asset.

The Reward

• The A-Team: Work alongside high-performing talent in the industry.
• Accelerated Growth: The slope of your learning curve here will be vertical. You will touch more production systems in one year than you would in five years at a bank.
• Top-Tier Coverage: Premium benefits plan fully paid by nesto, including comprehensive insurance and unlimited access to telemedicine and mental health services for you and your family.
• Rest & Recharge: 4 weeks of vacation to ensure you stay at peak performance.
• Best-in-Class Tools: Access to the resources and tech you need to execute without friction.
• Working framework: the environment that makes you productive and enables teamwork.
