The role involves collaborating with product and design teams to ship reliable software while ensuring system performance and security. ## Job description Crafting the kind of backend that makes frontend work feel like cheating Hey there — we’re Kinship 👋 We’re building the Revit tools you wish existed. Our platform helps architects and engineers manage content, track usage, and make smarter decisions with less hassle. We’re looking for a backend-focused engineer who enjoys building clean APIs, designing resilient systems, and keeping things fast, simple, and secure. Someone who’s comfortable working in PHP, knows their way around Docker, and can help us make the most of AWS to ship reliable software at speed. ## What You'll Do - Build and maintain backend services in modern PHP - Design and implement APIs consumed by our frontend and desktop apps - Use Docker to standardize development and streamline deployments - Work with AWS services (e.g. ECS, S3, RDS, CloudWatch) to keep our systems fast and reliable - Collaborate with product, design, and other engineers to ship features - Write tests and monitor performance so we can trust our stack at scale ## What We're Looking For You don’t need to tick every box, but here’s what would help you succeed: - Strong experience with PHP (we use PHP 8+) - Familiarity with containerized environments using Docker - Product mindset — you think in terms of user value, not just technical correctness - Clear communicator and thoughtful collaborator - Someone who’s excited to work in a small, fast-moving team - Knowledge of Laravel or Symfony - Comfortable with AWS basics — think deploying apps, storing files, managing databases - Experience designing or evolving APIs in production - Familiarity with CI/CD pipelines - Interest in DevOps, observability, or developer tooling ## What We Offer - Competitive salary - A beautiful, plant-filled office in central London (by Southwark tube station) and good coffee (obviously) - A no-BS team of people who love building great software together - Real autonomy and influence over product and tech decisions - A company that believes in work-life balance ## About Kinship ## Company Overview - **One-liner**: Kinship provides a cloud-based Revit content management, project tracking, and analytics platform that helps architecture and engineering teams find, manage, and optimize their BIM data. - **Entity Type**: Private (bootstrapped / independent – not backed by venture investors) - **Headquarters**: London, England (primary office) with a secondary office in Irvine, California, USA - **Founded**: Not publicly available - **Founders**: Jose Fandos (CEO & Co-Founder), Gary Sprague (Co-Founder & Head of Product) ## Core Business - **Primary industry**: Architecture, Engineering & Construction (AEC) software, specifically BIM (Building Information Modeling) for Autodesk Revit - **Target customers**: B2B – architecture and engineering firms of all sizes (trusted by 300+ firms worldwide with 25,000+ users) - **Mission/Purpose**: “Make it easy to get the most out of Revit” / “Making BIM simple, scalable, and human” ## Products & Services - **Kinship Revit Add-in**: A plugin that brings content search, loading, and management directly inside Revit. Users can find families, types, and components instantly without leaving the modeling environment. - **Content Management Platform**: A web-based tool to organize, version, and govern Revit content libraries (shared, restricted, project-specific). Includes lists, collections, and metadata management. - **Project & Analytics Dashboard**: Tracks models, sync times, warnings, crash reports, quantities, and content usage. Provides health checks and parameter data reports. - **API & SQL Access**: Available on the Enterprise plan for deeper integration and custom reporting. ## Market Standing - **Valuation**: Not disclosed (bootstrapped) - **Key Metrics**: 300+ customer firms, 25,000+ users, 100,000+ models tracked, 1,000,000+ Kinship searches, 40,000,000+ families managed - **Notable Investors/Partners**: None – the company is independent and customer-funded - **Growth Signals**: 12 employees (+37.5% YoY headcount growth per LinkedIn), expanding customer base across 6 countries, active hiring for engineering and product roles ## Competitive Advantages - **Independence**: No investor pressure allows long-term, customer-first decision making and flexible pricing. - **Deep Revit Integration**: Purpose-built for Revit, not a generic BIM tool; add-in provides seamless in-application search and loading. - **AEC Expertise**: Founders and team have deep experience in both BIM workflows and software development. - **Data Richness**: Automatic tracking of family health, model metadata, and project analytics that competitors often lack. ## Strategic Focus - **Product Excellence**: Shipping meaningful features, iterating based on user feedback, and maintaining high design/UX standards. - **Customer-Driven Roadmap**: Listen closely to architecture and engineering teams to solve their biggest pain points. - **Controlled Growth**: Prioritizing quality over blitzscaling; growing the team selectively while expanding the customer base. ## Why Work Here - **Culture**: Small, ambitious team (≈12 people) with a “people over process” ethos. In-person collaboration is encouraged – London office is the hub, with remote team members across time zones. - **Policy**: In-office focused for London-based roles; hybrid flexibility for team members in other locations. - **Perks**: Good coffee, fast-moving ideas, meaningful impact on real-world building design tools. - **Engineering Culture**: Opportunity to shape the product from the ground up; stack includes C#/.NET, frontend (likely modern JS/TS), and backend work.
