TECHNICAL LEAD – CLOUD ARCHITECT (HANDS-ON)

Description

Job Summary: We are seeking a senior technical leader who is 100% hands-on to guide the modernization of a SaaS laboratory management platform—re-architecting and incrementally rewriting a legacy product into a modern, multi-tenant, cloud-native web platform on Azure. Key Highlights: 1. Lead the modernization of a market-leading SaaS laboratory management platform 2. Define and deliver the next generation of an essential product 3. Design architecture, write code, operate systems, and develop people WMI develops a **market-leading SaaS laboratory management platform** in Brazil. We are embarking on a **modernization journey**: migrating Autolac—a legacy application built in **Delphi**, currently hosted in an on-premises **data center with VMs**—to a **modern web platform, multi-tenant and cloud-native on Azure**, featuring **elastic scalability** and **cost efficiency**. We seek a **senior technical leader, 100% hands-on**, to **guide architecture, technical decisions, and execution**, build a high-performance team (8–9 people), and **lead by example**. **Role Mission** Drive the **incremental re-architecture and re-implementation** of Autolac, ensuring **smooth coexistence** between the legacy app (Delphi) and the new web application (unified experience without disruption), adopting **modern engineering practices** (DevOps, “you build it, you run it”), **end-to-end quality** (ATDD/BDD, automated testing), and **effective use of AI/code generation** to accelerate delivery while maintaining quality and security. **Key Responsibilities** * **Strategic Architecture** o Define the target **cloud-native Azure architecture** (multi-tenant, Linux containers, serverless, storage/DB, networking, security, observability, cost). o Plan the **incremental migration** (strangler pattern, BFF/adapters, feature flags), preserving UX and short-term compatibility with Delphi. o Establish **design standards** (decoupling, modularity, stable contracts) and engineering guidelines. * **Hands-on Delivery** o Code daily: **APIs, integrations, pipelines, IaC**, and critical frontend/backend components. o Build **coexistence layers** (proxy/BFF, adapters) to integrate legacy and new systems without disrupting customers. o Implement **CI/CD** (Azure DevOps/GitHub Actions), **IaC** (Bicep/Terraform), **GitOps**, and **observability** (logs, metrics, traces, alerts). * **Quality, Security & Operations** o Ensure **ATDD/BDD**, **unit/integration/e2e tests**, code reviews, and **quality gates** in pipelines. o Implement **authentication/authorization** (e.g., **Azure AD/Entra ID**), **data protection**, and **security-by-default** practices. o Operate with a **DevOps/SRE mindset** (“you build it, you run it”): SLI/SLO, runbooks, post-mortems, cost/FinOps, and **scale-to-zero** where applicable. * **Technical Leadership & Team Development** o **Build and develop** an 8–9 person team; mentor, coach, and elevate technical capability. o Facilitate **agile ceremonies**, align with Product/UX/Business, and **communicate clearly** risks, trade-offs, and the technical roadmap. **Requirements (Mandatory)** * **10+ years** of software engineering experience with **proven track record** in **legacy system modernization** and delivery of **cloud-native web applications** in **enterprise/mission-critical** contexts. * Solid experience in **architecture, design, and implementation** of **multi-tenant solutions on Azure** (Linux containers, managed services, serverless components). * Real-world **operations experience**: production troubleshooting, **safe releases**, **CI/CD**, **observability** (logging, monitoring, alerting), **IaC**, and **GitOps**. * **DevOps mindset** (“you build it, you run it”) and **healthy engineering practices**: clean design, decoupling, clear abstractions, **code reviews**, **automated testing** (ATDD/BDD, unit, integration), **quality gates**. * **Authentication, data protection, and security** applied to web systems (including multi-tenant). * **Practical experience** with **AI for software engineering** and **agentic code generation** (e.g., Copilot/Cursor/Claude/etc.) to accelerate migrations without compromising quality. * **Agile/Incremental**: ability to deliver in slices, using feature flags and zero-downtime whenever possible. * **Target stack (flexible)**: strong experience in **C#/.NET** **or** equivalent language (Java/Node/etc.) and a **modern frontend framework** (Angular/React/Vue). Ability to **quickly learn and adopt** the preferred stack. * **Fluent Portuguese**. **Basic English** is a plus. **Nice-to-Haves** * Advanced **Azure** expertise (Containers/Container Apps/Kubernetes, Functions, Azure SQL/Serverless, Storage, Service Bus/Event Grid, API Management). * **Active Directory / Entra ID**, SSO, and RBAC. * **Migration patterns** (strangler fig, BFF, anti-corruption layer), **legacy-web coexistence**, and **secure data migration**. * **CQRS/Event-driven** architectures, caching/distribution, performance tuning, and **resilience** (circuit breaker, retries, idempotency). * **SRE/FinOps**: SLI/SLO, error budget, cost per tenant/module, **scale-to-zero**. * Experience in **healthcare/laboratories** and/or compliance (e.g., LGPD). **Soft Skills** * **Technical excellence** with an **action-oriented mindset**; ownership and **autonomy**. * **Clear communication** and collaboration with Product/UX/Business. * **Attention to detail** and uncompromising commitment to **quality**. * **Mentoring and coaching** of high-performance teams. * **Continuous learning** and openness to new techniques (including AI). **Why Join WMI?** You will **define and deliver** the next generation of an essential product for Brazil’s laboratory ecosystem, **leading the technical transformation** with **autonomy**, **direct business impact**, and **modern standards** (DevOps, cloud-native, applied AI). This is a role for those who want to **build**—architect, code, operate, and **develop people**—all at once.
