We don’t need an architect who draws boxes and walks away. We need one who ships the design and carries the pager. Techdome is a profitable, product-driven engineering company with 80+ engineers building healthcare, fintech, AI, and SaaS products. Our systems store sensitive patient data and move real money for large user bases. We’re looking for a senior technical leader who thinks of production as the true test of any design and takes responsibility for the result. What you’ll do • Own the architecture: Lead system design, API contracts, data modeling, security, scalability, observability, and cloud spend across our products. • Keep systems reliable: Be accountable for uptime, latency, and throughput as our user base grows. • Design for security from day one: Build safe handling of PHI and payment flows, with compliance built into the architecture rather than added later. • Drive cloud-native delivery: Run MERN-based platforms on AWS, GCP, or Azure with Kubernetes, CI/CD pipelines, infrastructure as code, and proper secrets management. • Make the hard calls: Decide between monolith and microservices, choose event-driven patterns, evaluate third-party integrations, and weigh build against buy. • Fix what’s broken: Step into production incidents, trace root causes, and resolve performance, scaling, and availability problems. • Set the standards: Create reference architectures, reusable patterns, and practical guidelines that 80+ engineers can follow. • Stay hands-on: Write code, lead design reviews, and review pull requests regularly. • Grow leaders: Mentor senior engineers and help build the next group of tech leads. What you bring • 8+ years in software engineering, with a track record of owning architecture decisions • Experience running a live production system with 100,000+ users (required) • A history of diagnosing and resolving serious scale and performance bottlenecks • Strong hands-on skills in Node.js and React (MERN preferred) • Solid architecture experience on AWS, GCP, or Azure • Experience in healthcare, fintech, payments, insurance, or another high-security domain • Deep knowledge of distributed systems, API design, databases, and reliability engineering • The ability to explain and defend your technical choices to engineers and non-technical stakeholders alike Nice to have • Direct experience with HIPAA, PHI handling, or PCI-DSS compliance • Working knowledge of Stripe, Braintree, or tokenization • Experience with high-availability, event-driven, or microservices architectures • Background in SaaS, consulting, or a venture studio • Daily use of AI coding tools like Claude Code, Cursor, or GitHub Copilot Why Techdome? • Your designs reach production quickly and affect real users • You set engineering standards for a large, growing team • A profitable, stable company with little red tape • Products used by customers around the world
