Job Title

Location: Remote (Toronto preferred, Canada or UK-friendly time zones) Type: Permanent Contract, full-time Are you a seasoned Full Stack or Backend-leaning Developer who loves solving real, technical problems, not shipping enterprise spaghetti code? Want to help build next-gen cloud tools powered by AI, complex data modelling, and interactive 2D/3D visualisation? An innovative technology company within the construction-tech and engineering-solutions space is growing its product team. Theyre building modern, cloud-based applications used globally, and youll work closely with an exceptional Head of Product to shape two major new platforms currently in development. About the company: This is a small, senior, highly technical team that builds modern, cloud-native design and estimating software used in complex temporary works and engineering workflows. Their upcoming product suite includes: A new intelligent design engine with AI-assisted modelling and automated calculations A web-based estimating platform that uses 3D models to generate accurate metrics, plans, and costs They value clean architecture, thoughtful engineering, and building things the right way , not rushing features at the cost of maintainability. Youll take end-to-end ownership of features on two major new products, working across backend services, web clients, data modelling, and AI integrations. Expect a mix of architecture, hands-on building, problem-solving, and collaborating on product direction. You will: Build and refine backend services using C# / ASP.NET Core Develop React TypeScript front-end components for highly interactive UIs Work with PostgreSQL, including JSON-based modelling for complex nested structures Help shape clean, scalable APIs (REST GraphQL) Integrate AI workflows (e.g., OpenAI/AWS) to transform natural-language instructions into design logic Contribute to lightweight 2D/3D viewer tools (Three.js, WebGL, GLB/gLTF handling) across both products Collaborate directly with the Head of Product on technical decision-making Deploy and support applications in AWS environments Participate in code reviews, architecture discussions, and roadmap planning We are looking for: Someone who is curious, hungry to learn, and excited by challenging technical problems , especially involving AI, 3D modelling, or data-heavy workflows. Must-have skills: 5 years in software engineering (Full Stack or Backend-majority) Strong backend capability with C#, ASP.NET Core (6) , ideally .NET 8 Solid front-end experience with React TypeScript Strong database background, ideally PostgreSQL with EF Core Experience building well-structured APIs (REST; GraphQL beneficial) Cloud deployment experience (AWS preferred) Strong problem-solving, communication, and ability to work in a remote, async-friendly team Nice to have: Exposure to 3D/2D visualisation frameworks (Three.js, WebGL, canvas libraries) Experience working with GLB/gLTF models or CAD/BIM toolchains AI/ML integration experience (OpenAI, Bedrock, etc.) Background in engineering, construction tech, or modelling-heavy products Experience in early-stage product environments where requirements evolve quickly Why join: Highly collaborative role working directly with senior product and engineering leaders Opportunity to solve genuinely complex, interesting technical challenges (3D graphics, AI design commands, intricate data modelling) High autonomy with a team that values craftsmanship and clean architecture Fully remote role with preference for EST-aligned hours Apply now: If youre excited by the idea of shaping AI-powered engineering tools, love backend C# development, and enjoy working across the stack on technically meaningful products, this is a role where youll have real influence and long-term impact.
