Lead Software Architect

Job Title: Lead Software Architect (Hands-On)

Location: Doha, Qatar

Company: Lillia

Employment Type: Full-time

Lillia is at the forefront of Health Tech innovation. We are developing an advanced agentic solution dedicated to chronic care management. Our ecosystem comprises intelligent agentic workflows, a patient-facing mobile application, and a robust administration platform. We are driven by the mission to revolutionize patient care through autonomous, data-driven technology.

As our product matures, Lillia is preparing to transition our infrastructure to its next evolutionary stage. We are seeking a Lead Software Architect with deep technical expertise and a strategic mindset to guide this transformation.

You will be responsible for auditing our current architecture and proposing a clean, scalable approach for our "Version 2.0" infrastructure. You will determine what should be salvaged and what requires reengineering. Crucially, this is a hands-on role; you will not only design the solution but actively participate in its development and implementation.

• Architectural Strategy & Design: Analyze the existing codebase and infrastructure to design a scalable, secure, and high-performance microservices architecture.
• Infrastructure Evolution: Lead the migration and re-engineering of our database structures, global data flows, and cloud infrastructure on Google Cloud.
• Security & Compliance: Embed security and compliance into the architectural foundation, ensuring strict adherence to standards required in a highly regulated industry.
• Hands-On Development: Actively code and implement core components of the new architecture, serving as a standard-bearer for code quality and design patterns.
• Agentic Systems: Architect and optimize complex agentic workflows to support our chronic care management solutions.
• Technical Leadership: Mentor the engineering team, drive technical decision-making, and foster a culture of engineering excellence using modern tooling.

• Experience: Minimum of 15 years of experience in software development, with at least 5 years in a Lead Architect or Technical Lead position.
• Regulated Industry Background: Proven experience working in highly regulated sectors (Healthcare, FinTech, etc.) with a deep understanding of compliance, data privacy, and security protocols.
• Agentic & AI Workflows: Demonstrated experience designing and building agentic workflows and integrating AI-driven logic into enterprise applications.
• Modern Development Practices: Proficiency with "vibe coding" tools (AI-assisted coding environments) to accelerate development and maintain flow.
• Cloud Native: Strong expertise in distributed systems and microservices.

We are looking for expertise in the following technologies:

• Languages: Java, Python, JavaScript/TypeScript.
• Frameworks: Spring Boot, NodeJS, React.js.
• Data: MongoDB, PostgreSQL.
• Cloud: Google Cloud Platform (GCP).

• Direct experience with Electronic Health Records (EHR) integrations.
• Experience with FHIR standards and HL7.
• Experience with MCP and A2A protocols

This is a unique opportunity to define the technical future of a product that directly impacts patients' lives. If you are a pragmatic architect who loves to code and wants to solve complex challenges in the healthcare space, we want to hear from you.
