Senior Full-Stack Developer


Location: Ottawa, ON (Remote)


About the Role


We are looking for a Senior Full-Stack Developer to join one of our development squads and help build new features for the 1VALET smart-building platform. This role is hands-on and product-focused, working across the stack - from Angular front-end experiences to .NET backend services - and includes integrations with hardware and third-party vendors (smart locks, entry systems, building systems, etc.). You'll collaborate closely with Product, Hardware, QA, and Operations teams to deliver scalable, reliable features used in live residential and commercial buildings.


What You'll Do


Design, build, and maintain end-to-end features across front-end, backend, and data layers

Develop and optimize Angular front-end applications with a focus on performance and usability

Build .NET (C#) backend services, APIs, and integrations

Work with MS/Azure SQL for data modelling, querying, and performance optimization

Use Elasticsearch for search, analytics, and log-driven features

Implement and maintain hardware and vendor integrations (IoT devices, access control systems, third-party APIs)

Collaborate with Product Managers to translate requirements into technical solutions

Work with QA to ensure high quality through testing, debugging, and production support

Participate in architectural discussions and contribute to technical direction

Support and improve existing systems while helping shape new platform capabilities


What You Bring


6+ years of professional experience as a Full-Stack Developer

Strong hands-on experience with:


Angular

.NET / C# (Web APIs, services)

MS/Azure SQL (schema design, performance tuning)

Elasticsearch


Experience designing and consuming REST APIs

Exposure to hardware / IoT integrations or complex third-party system integrations (strong asset)

Solid understanding of scalable, distributed systems

Experience working in Agile / squad-based teams

Strong problem-solving skills and ability to work independently in a remote environment

Clear communication skills and a collaborative mindset

Experience using AI-assisted development tools (e.g., Replit AI, Claude Code, GitHub Copilot) to improve productivity, code quality, debugging, or prototyping


Nice to Have


Experience with cloud platforms (Azure)

Knowledge of message queues, event-driven systems, or real-time data flows

Prior experience in PropTech, IoT, or building management systems

Experience supporting production systems used by real customers in the field


Why Join 1VALET


Work on real-world systems deployed in buildings across North America

Be part of a platform that blends software, hardware, and operations

High ownership, meaningful technical challenges, and visible impact

Collaborative, product-driven engineering culture

Remote role with a strong Ottawa-based engineering presence
