Position Summary

We are seeking a highly skilled Senior Software Engineer to own the backend architecture, data processing, and modernization of InfoSend’s core EBPP (Electronic Bill Presentment & Payment) and digital delivery platforms. You will be the technical driver for scaling our PHP-based backend systems, optimizing high-volume transaction queues, and leading the strategic modernization of our client-facing portals from legacy jQuery/HTML to React/Next.js. This is a high-ownership role for an experienced engineer who thrives in complex environments, drives CI/CD excellence, and ensures SOC2/PCI compliance without sacrificing delivery velocity.

Job Responsibilities:

Backend Architecture & System Scaling

• Design, develop, and scale backend-heavy PHP services and REST APIs for EBPP job submission, invoice processing, and production tracking
• Optimize SQL databases (PostgreSQL/MySQL) and manage consumer queues for high-volume, distributed transaction processing
• Integrate complex data workflows and ensure high availability for mission-critical print/mail production systems

Strategic Modernization & Front-end Evolution

• Drive the technical execution of modernizing our client portals. Architect and build new UI components using React, Next.js, and Tailwind CSS
• Maintain, support, and incrementally refactor the existing jQuery/HTML frontend during the transition phase
• Leverage AI prototyping tools and coding assistants to accelerate UI/UX development and modernization efforts

CI/CD Ownership & DevOps Integration

• Own and optimize GitLab CI/CD pipelines for the Digital Delivery team. Manage version control, automated testing, and rollouts
• Implement zero-impact release strategies (canary deployments, automated rollbacks) to ensure reliable, weekly feature deliveries
• Partner with Platform Engineering to ensure seamless "Metal-to-Application" lifecycle integration and optimize deployment times

Security, Compliance & Data Integrity

• Ensure application security (OAuth), data integrity, and compliance with industry standards (including SOC, HIPAA, PCI, if applicable, etc.)
• Embed security-by-design principles into the SDLC and drive automated compliance evidence collection to maintain continuous audit readiness
• Manage secrets, enforce least-privilege access, and conduct regular security reviews to protect sensitive client billing and payment data
• Technical Leadership, Documentation & Process Improvement
• Document code / architecture; lead code reviews, process improvements, deployments/migrations
• Act as the technical anchor for the team: establish and enforce coding standards, troubleshoot critical system issues, and mentor junior/mid-level engineers
• Drive continuous improvement initiatives by identifying technical debt, optimizing legacy workflows, and elevating the overall engineering maturity of the Digital Delivery team

Required Experience & Skills

• Experience: 7+ years of professional software engineering experience, with a heavy focus on backend development and distributed systems
• Backend Mastery: Deep proficiency in PHP 8+ and PHP frameworks, building REST APIs, microservices, and managing message queues (RabbitMQ is preferred)
• Database & Data Processing: Strong SQL experience optimizing relational databases (PostgreSQL/MySQL) for high-throughput transactional systems
• DevOps & CI/CD: Hands-on mastery of GitLab CI/CD pipelines and full SDLC ownership. Experience implementing automated testing and zero-downtime deployment strategies
• Core Frontend & Web Technologies: Strong proficiency in core web programming languages (PHP, HTML/CSS, jQuery) with extensive experience maintaining and troubleshooting legacy client portals
• Security Mindset: Strong understanding of authentication/authorization (OAuth, JWT), secure coding best practices, and experience building systems in regulated environments

Preferred Qualifications

• Experience maintaining or migrating legacy codebases (jQuery/HTML or FoxPro)
• Experience with React, Next.js, and Tailwind CSS for client portal modernization initiatives
• Familiarity with leveraging AI coding assistants for rapid prototyping and legacy code translation
• Ability to work independently and communicate effectively in a collaborative environment
• Linux development environment experience is a plus
• Bachelor’s degree in Computer Science, Software Engineering, or equivalent experience
