What we’re looking for?

We are seeking an experienced Senior Backend Engineer with strong Python and AWS expertise to work with an international client that provides life insurance protection targeted to the middle‑American market.

The role focuses on application modernization and cloud transformation. You’ll analyze, decompose, and re‑architect legacy .NET applications, converting them into modern, scalable Python‑based solutions running on serverless AWS infrastructure.

The ideal candidate has a strong background in building cloud‑native web applications, understands legacy systems well enough to navigate and refactor existing .NET codebases, and can produce clear, structured technical documentation to support knowledge transfer and long‑term maintainability.

As a Senior Backend Engineer, you’ll design, develop, and maintain high‑quality software solutions that meet internal team needs while collaborating closely with architects and cross‑functional stakeholders to deliver scalable, reliable, and well‑documented systems.

Key responsibilities

• Analyze and understand legacy .NET applications to plan modernization strategies
• Design and implement modern Python‑based replacements for legacy systems, leveraging serverless AWS infrastructure (Lambda, Step Functions, API Gateway, etc.)
• Collaborate with the architecture team to ensure implementations align with enterprise engineering standards
• Identify opportunities for re‑architecture and process improvement during migration work
• Design, develop, test, and deploy data migration and management tools
• Write clean, maintainable, and efficient code that meets coding standards and best practices
• Create comprehensive onboarding documentation and technical guides to enable smooth handoffs to core engineering teams
• Participate in code reviews and provide feedback to improve code quality
• Work with QA engineers to develop and execute test plans, ensuring high software quality
• Troubleshoot and debug issues in both legacy and modernized systems and provide timely resolutions
• Keep up‑to‑date with emerging trends and technologies in software engineering and recommend improvements to the development process

Qualifications

• Bachelor's degree in Computer Science, Engineering, or related field
• At least 6 years of experience in software engineering
• Strong proficiency in Python programming language
• Strong proficiency in Amazon Web Services (AWS), particularly serverless technologies (Lambda, Step Functions, API Gateway, etc.)
• Strong proficiency with AI‑assisted development tools (Claude, Amazon Q, Copilot, or similar)
• Strong proficiency with database technologies such as SQL or NoSQL databases
• Experience with software development tools and processes such as Agile/Scrum, Git, IaC, and CI/CD pipelines
• Experience building enterprise‑class applications with attention to quality and reliability
• Strong technical writing skills with the ability to create clear documentation for knowledge transfer
• Strong problem‑solving skills and the ability to work in a team environment
• Excellent English communication and collaboration skills

It doesn’t hurt if you also have

• Experience modernizing or migrating legacy applications to cloud‑native architectures
• Familiarity with .NET Framework/Framework Core sufficient to read and understand legacy codebases
• Experience with Python web frameworks
• Strong experience working with serverless, high‑availability, and high‑scalability architectures
• Familiarity with enterprise architecture design patterns
• Experience with data migration strategies and security best practices
• Familiarity with Okta or other SSO & SAML strategies and technologies
