Original job description

Job Summary

We are seeking an Intermediate Developer to build and scale distributed, event-driven applications including APIs, web apps, and background workers within our IT delivery teams. This role focuses on the dual mission of enhancing our existing operational suite while engineering new, high-performance solutions to ensure faster and more reliable software delivery.

As a key member of the Operational Products Team, you will maintain the backbone of our critical systems while spearheading our transition to a modern, cloud-native architecture. You will act as the bridge between legacy stability and future-proof innovation, migrating services from legacy .NET Framework to .NET 8 and integrating complex workflows using Mulesoft and RabbitMQ.

Duties & Responsibilities

Technical Requirements:

The .NET Evolution: 3–5 years of experience across the full .NET spectrum. You must be comfortable troubleshooting legacy ASP.NET/C# 3.5 codebases while being an expert in .NET 6/8 and latest versions of C#.
API Mastery: Strong experience developing and consuming both SOAP (WCF/Web Services) and RESTful APIs.
Messaging & Events: Proven experience with Event-Driven Architecture (EDA), specifically using RabbitMQ for asynchronous processing and service decoupling.
Integration: Hands-on experience (or a strong desire to master) Mulesoft Anypoint Platform for API management and system orchestration.
Data: Proficiency in SQL Server, including writing complex stored procedures and optimizing queries for high-transaction operational databases, updating data processes.

Core Responsibilities:

Legacy Maintenance: Maintain and patch existing .NET 3.5/4.x operational products, ensuring "zero-downtime" and high stability for mission-critical business functions.
Modernization: Lead the refactoring and migration of monolithic legacy services into scalable, containerized (Docker/K8s), or serverless microservices using .NET 8.
Integration Engineering: Design and implement robust integration flows using Mulesoft Anypoint Platform and .NET 8 to orchestrate data across disparate internal systems and external partner APIs.
System Reliability: Optimize Event-Driven Architecture (EDA); monitoring and tuning Applications, APIs, RabbitMQ exchanges and consumers to ensure high throughput and message persistence.
Cross-Functional Collaboration: Partner with Business, Product, and DevOps teams to deliver incremental value through Agile methodologies, balancing feature requests with technical debt reduction.
Governance & Documentation: Drive engineering excellence by contributing to technical documentation, standardizing CI/CD processes, and ensuring compliance with security protocols.
Innovation (AI-First): Proactively identify opportunities to integrate Generative AI to accelerate modernization and improve operational efficiency and quality.

Behavioural Competencies

Concern for Safety: Identifying hazardous or potentially hazardous situations and taking appropriate action to maintain a safe environment for self and others.
Teamwork: Working collaboratively with others to achieve organizational goals.
Passenger/Customer Service: Providing service excellence to internal and/or external customers (passengers).
Initiative: Dealing with situations and issues proactively and persistently, seizing opportunities that arise.
Results Focus: Focusing efforts on achieving high quality results consistent with the organization’s standards.
Fostering Communication: Listening and communicating openly, honestly, and respectfully with different audiences, promoting dialogue and building consensus.

Qualifications

Bachelor’s degree in Computer Science, Software Engineering, or equivalent professional experience.
4+ years of professional software development experience, with a heavy focus on the .NET ecosystem (C#). Mulesoft experience would be an advantage.
Proven track record of migrating legacy applications (e.g., .NET 3.5/4.x Framework) to modern, cross-platform architectures (e.g., .NET 6/8/Core).
Hands-on experience designing and implementing Event-Driven Architectures using RabbitMQ or similar message brokers (Kafka, Azure Service Bus).
Deep expertise in developing and securing both RESTful APIs and legacy SOAP (WCF) services. Experience with Mulesoft Anypoint Platform for orchestration is a significant plus.
Strong analytical skills with the ability to "reverse engineer" undocumented legacy code and refactor it into clean, maintainable microservices.
Experience guiding technical discussions, performing code reviews, and collaborating with cross-functional teams (Product, Ops, and Business).
Familiarity with Docker/containerization and CI/CD pipelines (e.g., GitHub Actions, Jenkins, or Azure DevOps) for automated deployment.
Strong understanding of relational databases (SQL Server), including optimizing complex queries and managing data migrations during version upgrades.
Familiarity with AI-assisted development (e.g., GitHub Copilot) and an interest in applying AI/ML to improve operational efficiency and quality.

Location

Toronto Downtown Office (250 Yonge Street)

Company Description

Since 2006, Porter Airlines has been elevating the experience of economy air travel for every passenger, providing genuine hospitality with style, care and charm.
