- Design integration strategies for legacy systems and APIs, including subdomain remapping where required.
- Establish architecture standards, design patterns, and best practices across teams.
Application & Platform Engineering
- Guide development of application-level microservices acting as an intermediate layer between UI and core platform services.
- Architect usage of Azure PaaS services, including Azure SQL and Cosmos DB for domain-based data ownership.
- Ensure observability, scalability, and performance optimization are built into all services.
- Drive adoption of AI-assisted engineering tools for code, testing, and documentation efficiency.
Engineering Excellence
- Champion Test Driven Development (TDD) and enforce high standards for automated testing (unit, integration, regression).
- Lead code reviews, static analysis, and refactoring initiatives to maintain code quality.
- Define and enforce CI/CD best practices, ensuring continuous deployment with frequent, reliable production releases.
- Promote DevOps maturity, including containerization and infrastructure as code.
Product Mindset & Collaboration

- Drive technical decision-making aligned with business goals, including trade-off analysis.
- Collaborate cross-functionally with QA, design, infrastructure, and operations teams.
- Advocate for user-centric design and engineering decisions.
Ownership & Leadership
- Take end-to-end ownership of architecture and delivery—from concept to production impact.
- Act as a technical leader and mentor, guiding teams on TDD, DDD, and modern engineering practices.
- Identify risks early, communicate effectively, and drive resolution across teams.
- Support and evolve existing systems with continuous improvements and enhancements.
Continuous Improvement & Innovation
- Drive improvements in architecture, performance, and engineering processes.
- Stay current with industry trends in microservices, cloud-native development, and AI in software engineering.
- Foster a culture of engineering excellence and continuous learning.
Required Qualifications
- 10+ years of professional software engineering experience in product-based organizations (healthcare payments or similar domains preferred).
- Proven experience in a Software Architect or Senior Technical Leadership role.
- Strong expertise in Test Driven Development (TDD) with hands-on experience in automated testing frameworks.
- Proficiency in C#/.NET (Node.js preferred; other modern frameworks acceptable).
- Extensive experience with:
- Microservices and event-driven architectures
- Domain-Driven Design (DDD)
- Azure cloud platform (AKS, Azure SQL, Cosmos DB)
- Strong experience in DevOps practices: CI/CD pipelines, containerization, infrastructure as code.
- Experience with system integration and legacy modernization.
- Excellent communication and stakeholder management skills, with the ability to translate technical concepts into business outcomes.
Preferred qualifications
- Bachelor's or master's degree in computer science, engineering or a related field.
- Experience developing applications using a microfrontend architecture and design-system.
- Familiarity with healthcare or payment processing domains.
- Experience using generative AI for code generation and documentation.
What success looks like
A successful software engineer developing our consumerdirected healthcare applications will:
- Deliver business value by shipping features that solve real customer problems and improve user experience; this requires understanding the product context.
- Maintain high quality by championing TDD, writing comprehensive tests and keeping the system stable during modernization.
- Take ownership of features endtoend from design to deployment and support and proactively seek improvements.
- Collaborate effectively with crossfunctional teams and communicate clearly with technical and nontechnical stakeholders.
- Help shape the nextgeneration architecture by contributing domain models, identifying technical debt, and mentoring teammates on microservices and eventdriven patterns.
Why join us
You will be part of a team tackling challenging modernization work on a scale. Our consumerdirected healthcare platform is critical to Alegeus mission of simplifying healthcare payments, and this role offers the opportunity to drive tangible impact. You will work with supportive colleagues, leverage cuttingedge tools (including AIassisted development), and develop your skills in microservices, eventdriven architectures, testdriven development and cloud engineering.
