# Principal Engineer (MERN)

Design it, build it, and own it in production. Anyone can draw a system diagram. What sets great architects apart is what happens after: whether the design holds when traffic grows tenfold, whether security survives a real audit, and whether teams can still build on it two years later. Techdome designs and runs production-grade platforms in FinTech, Healthcare, AI, SaaS, and more, including our own products JustInterview.ai (AI hiring) and Sparrow (API testing). Our systems handle sensitive patient data and real financial transactions at scale. We’re looking for a hands-on Software Architect to shape how these platforms are built, write code alongside the team, and stay accountable for how they perform in production. What You’ll Do Own the architecture: System design, APIs, data models, security, scalability, observability, and cloud cost. Build security in: Design PHI and payment flows with compliance part of the architecture, not a retrofit. Drive cloud-native delivery: MERN platforms on AWS/GCP/Azure with Kubernetes, CI/CD, IaC, and secrets management. Make the hard calls: Monolith vs. microservices, event-driven design, integrations, build vs. buy. Decide, document, and stand b
