Principal Software Engineer

Job Description:

The Max Maintenance team is seeking an experienced Principal Software Architect to lead the modernization and cloud transformation of a legacy .NET web application with a SQL Server backend. This role requires deep expertise in AWS cloud services—including API Gateway, AWS Lambda, Step Functions, DynamoDB, and Neptune—to re-architect the system into a scalable, serverless, event-driven platform. The ideal candidate will bring a strong architectural vision, hands-on technical ability, and a passion for mentoring and guiding development teams through digital transformation initiatives.

Are you flexible and excited about working in a fast-paced, dynamic team environment? Come join a diverse, motivated team.

Key Responsibilities:

• Lead the end-to-end cloud transformation strategy for a legacy .NET/SQL Server web application.
• Design and implement scalable, secure, and serverless AWS-native architectures using services such as API Gateway, AWS Lambda, Step Functions, DynamoDB, and Neptune.
• Define and drive data migration strategies, transforming relational data models into NoSQL (DynamoDB) and graph-based (Neptune) storage paradigms.
• Establish best practices for infrastructure-as-code, CI/CD pipelines, and monitoring using AWS CloudFormation, CDK, or Terraform.
• Provide hands-on technical leadership to development teams, ensuring high code quality and adherence to cloud-native principles.
• Guide teams through cloud adoption, service decomposition, and event-driven design patterns.
• Mentor engineers on AWS technologies, microservices architecture, and best practices in DevOps and modern software engineering.
• Write and review code for critical services, APIs, and data access layers using appropriate languages (e.g., Python, Node.js).
• Design and implement APIs for internal and external consumers, ensuring secure and reliable integrations.
• Perform architecture reviews, threat modelling, and enforce rigorous testing practices including automated unit, integration, and load testing.
• Work closely with stakeholders, project managers, and cross-functional teams to define technical requirements and delivery milestones.
• Translate business goals into technical roadmaps and prioritize technical debt reduction and performance improvements.
• Engage stakeholders to manage expectations and provide clear communication on technical progress and risks.
• Stay up-to-date with AWS ecosystem updates, architectural trends, and emerging technologies.
• Evaluate and prototype new tools, services, or architectural approaches that can accelerate delivery and reduce operational complexity.
Champion a DevOps culture with continuous delivery, observability, and security-first development.

Requirements:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.
• 8+ years of software development experience, with at least 3 years architecting cloud-native solutions on AWS.
• Expertise in AWS services such as API Gateway, Lambda, Step Functions, DynamoDB, Neptune, IAM, CloudWatch.
• Experience with legacy application modernization and cloud migration.
• Proficiency in .NET stack and ability to map legacy components to cloud-native equivalents.
• Strong knowledge of distributed systems, serverless design, data modelling (both relational and NoSQL/graph), and security best practices.
• Proven leadership and mentoring abilities in agile software teams.
• Strong problem-solving, analytical, and decision-making skills.
