About the Role

Design scalable, secure, and highly available cloud architectures using AWS best practices for performance, resiliency, and cost optimization

Actively leverage AI-assisted development tools (e.g., copilots, code generation, automation) to significantly accelerate delivery and reduce manual effort

Identify opportunities to embed AI into the product itself—improving invoice processing, data extraction, workflows, and user experience

Build with a mindset of speed, iteration, and continuous improvement using AI as a core part of the development lifecycle

Create clean, modern user interfaces using React, Tailwind CSS, Bootstrap, JavaScript, and Thymeleaf where appropriate

Bring a strong eye for design, usability, and user experience to every solution

Architect and implement scalable multi-tenant SaaS platforms deployed on AWS

Make and own architecture decisions across application, cloud infrastructure, security, and DevOps

Design and optimize cloud and relational database solutions using PostgreSQL, SQL Server, and AWS managed database services

Develop secure integrations with ERPs and external systems using REST APIs, event-driven architectures, messaging, and file-based interfaces

Translate complex accounts payable and invoice processing workflows into scalable enterprise software solutions

Build and maintain CI/CD pipelines and deployment automation to enable reliable, repeatable software releases

Monitor, troubleshoot, and optimize production environments using AWS observability and operational best practices, including L3 support and incident resolution

Collaborate across engineering and product teams using Agile methodologies and Jira to plan, track, and deliver high-quality software
