Software Development Engineer Payroll Tax And Accounting Tech

Description

Are you interested in building a high-performance, globally scalable gross-to-net payroll calculation engine with deep tax calculation capabilities that supports Amazons current and future growth? Are you seeking an environment where you can drive innovation leveraging the scalability and innovation with Amazons AWS cloud services? Do you have a passion for ensuring accurate financial calculations that directly impact employees? This is the job for you.

Amazons Payroll Tax & Accounting Technology team is looking for a results-oriented, driven Software Development Engineer who can help us create the next generation of distributed, scalable gross-to-net calculation infrastructure with sophisticated tax processing at its core. Our ideal candidate thrives in a fast-paced environment, enjoys the challenge of highly complex regulatory contexts that are typically being defined in real-time. We need someone to design and develop a single global system that processes gross earnings through complex multi-jurisdiction tax calculations to net pay for millions of employees, with local configuration driven by LLM-based rule extraction.

A Software Development Engineer (SDE) at Amazon works on real world problems on a global scale, owns their systems end to end and influences the direction of our technology that impacts hundreds of millions of customers around the world. You can expect to design flexible and scalable solutions, and work on some of the most complex challenges in large-scale computing by utilizing your skills in data structures, algorithms, and object oriented programming. Coming to Amazon gives you the opportunity to work on a small development team in one of our many rapidly growing organizations.

You will learn all about how to design, implement and test highly scalable solutions using AWS cloud platform and its many products, in challenging agile projects, working with best in class professionals.

In This Role You Will

• Build a globally deployed, locally configured gross-to-net calculation engine that leverages LLM-based rule extraction to formalize complex jurisdiction-specific tax regulations, including multi-layered tax calculations, YTD tracking, and statutory compliance requirements
• Design and develop deterministic tax calculation algorithms that handle employee withholding, employer tax obligations, and process gross earnings through deductions to calculate net pay across multiple countries
• Create accounting integration services that generate GL entries and journal entries for all necessary payroll entries, like earnings, tax, & benefits
• Implement GenAI shadow mode validation frameworks to ensure accuracy against existing systems
• Partner directly with Software Development Engineers (SDEs), Technical Program Managers, tax specialists, and payroll operations teams to understand features and continuously identify opportunities to build and deploy software solutions
  
  

Key job responsibilities

• Define high-level and low-level design for the global gross-to-net calculation engine with complex tax processing capabilities using the latest AWS technology in a large distributed environment
• Take the lead on defining and implementing engineering best practices for deterministic financial calculations and using data to define and improve operational best practices
• Help drive the architecture and technology choices for the LLM-based rule extraction pipeline and tax-centric gross-to-net calculation products
• Design, develop and deploy medium to large software solutions for Amazons global payroll tax calculation and gross-to-net accounting needs
• Raise the bar on code quality, including security, auditability, readability, consistency, and maintainability
• Leverage GenAI capabilities to build validation frameworks and continuously improve system accuracy
  
  

A day in the life
