Principal Software Engineer

JOB DESCRIPTIONThe 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 with real, day-to-day coding in Python and other languages to re-platform the system to a scalable, serverless, event-driven architecture on AWS.Are you excited to design systems, write code, and mentor engineers in a pragmatic, delivery-focused environment? Join a diverse, motivated team.Key Responsibilities:1. Cloud Architecture and Migration Strategy: • 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.2. Hands-On Engineering (Python): • Write production Python for Lambda functions, API services, data/ETL pipelines, and event handlers; contribute 30-50% of your time to coding and code reviews.• Implement clean, well-tested modules using modern Python, package management, and test frameworks.• Apply sound algorithms and data structures; comfortably implement recursive and iterative solutions where appropriate (e.g., tree/graph walks, backtracking).• Champion engineering quality: TDD, meaningful code reviews, static analysis, and robust observability (structured logs, metrics, traces).3. Technical Leadership and Mentorship: • 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.4. Implementation and Quality Assurance: • 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.5. Collaboration and Planning: • 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.6. Innovation and Continuous Learning: • 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.ABOUT USEvery day, the oil and gas industry's best minds put more than 150 years of experience to work to help our customers achieve lasting success.
