You should be comfortable discussing code structure, service design, API contracts, data modeling, testing, deployment, and production failure modes. * Experience designing and operating microservices and event-driven systems in a cloud environment. Azure experience is preferred; AWS or GCP experience is transferable. * Strong understanding of TypeScript, Node.js, APIs, React-based application platforms, containerized workloads, Kubernetes, CI/CD, and infrastructure automation. * Experience with domain-driven design, service decomposition, integration architecture, and the tradeoffs between shared services, product services, and customer-specific extensions. * Practical experience with build-versus-buy decisions, vendor integration, platform consolidation, marketplace capabilities, or turning repeated integration patterns into reusable platform services. * Strong API and data architecture judgment, including REST, OpenAPI, event contracts, PostgreSQL, analytics handoffs, authorization, tenant/customer isolation, and auditability. * Proven ability to lead complex technical decision-making across engineering, product, security, infrastructure, operations, and executive stakeholders without relying on generic architecture theater. * Demonstrated ability to create architecture standards, decision frameworks, and reusable patterns that influence engineering execution without formal management authority. * Experience mentoring staff and principal-level engineers and architects. * Healthcare, payer, pharma, regulated-industry, SOC 2, HIPAA, or security-sensitive platform experience is strongly preferred. * Enterprise architecture experience is a plus, especially when paired with hands-on application architecture and delivery experience. * Excellent written communication. You can make architecture decisions clear, concise, and useful to the teams who need to execute them. ## Description * TypeScript, Node.js, NestJS, React, Next.js, Python * PostgreSQL, Azure Blob Storage, Snowflake * Azure Kubernetes Service, Azure API Management, Azure Service Bus * Dapr for service invocation and pub/sub * Terraform, ArgoCD, GitHub Actions, Docker * Auth0, OAuth2, OpenID Connect, API key support for integrations * Nx monorepo, API contract-first development, automated testing For this role, we especially value experience with: * Designing enterprise marketplace platforms, multi-tenant systems, customer-isolated data boundaries, or partner integrations * Regulated platform capabilities in healthcare, payer, or pharma environments * Enterprise architecture paired with hands-on application architecture and delivery execution Hybrid This role requires employees to be in-office based on our hybrid workplace model, balancing purposeful in-person collaboration with flexibility. For most teams, this means coming into the office two days each week. Employees living more than 50 miles from an office location will work with their manager to determine in-office time based on business need. ## Related Videos - [Next Level Enterprise Architecture: Modular, Flexible, Scalable, Multichannel and AI-Ready?](https://www.wearedevelopers.com/videos/1017-next-level-enterprise-architecture-modular-flexible-scalable-multichannel-and-ai-ready) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Azure-Well Architected Framework - designing mission critical workloads in practice](https://www.wearedevelopers.com/videos/1529-azure-well-architected-framework-designing-mission-critical-workloads-in-practice) - [Streaming AI Responses in Real-Time with SSE in Next.js & NestJS](https://www.wearedevelopers.com/videos/1630-streaming-ai-responses-in-real-time-with-sse-in-next-js-nestjs) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [How to Answer the Interview Question: “Why Do You Want to Be a Software Engineer?”](https://www.wearedevelopers.com/magazine/392-how-to-answer-the-interview-question-why-do-you-want-to-be-a-software-engineer)
