Original job description

Job Title: Java Developer

Duration: 06 Months Contract to Hire

Type: 3 days/week onsite (hybrid)

Location: Mississauga, ON

About the Role:

We're looking for a senior, architect-level engineer who can sit alongside our front-office users, including underwriters, bankers, and business stakeholders, and turn their needs into reliable, well-designed software. You'll be embedded with the business, owning solutions end to end: understanding the problem, designing the architecture, and building and shipping the work. The role is heavily backend, with enough front-end fluency to deliver complete solutions. You'll also use AI-assisted development tools (such as Devin and GitHub Copilot) to move faster without lowering the quality bar.

What You'll Do:

Work directly with underwriters, bankers, and other front-office stakeholders to understand workflows, pain points, and requirements
Translate business needs into scalable technical architecture and clear designs
Design and build backend services and APIs, primarily in Java and Spring Boot
Build and enhance user-facing features in Angular (or React) to deliver complete, usable solutions
Model and manage data across relational and NoSQL stores (Oracle, MS SQL Server, MongoDB)
Use AI coding tools to accelerate development, testing, and documentation, and review AI-generated output critically
Set technical direction, conduct design and code reviews, and mentor other engineers
Communicate trade-offs, timelines, and risks clearly to both technical and non-technical audiences
Support solutions in production and iterate quickly based on user feedback

Required Qualifications:

Significant experience as a senior or architect-level software engineer, with a track record of designing and delivering production systems
Strong backend expertise in Java and Spring Boot (REST APIs, microservices, security, performance tuning)
Hands-on experience with Oracle and/or MS SQL Server, plus MongoDB
Working knowledge of front-end development, with Angular preferred and React also welcome
Practical experience with AI-assisted development tools such as Devin and GitHub Copilot
Excellent communication skills and comfort working directly with business users, including senior stakeholders
Ability to work independently, manage ambiguity, and own outcomes

Preferred Qualifications:

Proficiency in Python for services, scripting, or data work
Experience in financial services, banking, or underwriting environments
Prior forward-deployed, solutions engineering, or client-facing technical roles
Experience with cloud platforms, CI/CD, and containerized deployments
Familiarity with event-driven architectures and messaging systems

Tech Stack:

Java, Spring Boot, Angular/React, Oracle, MS SQL Server, MongoDB, Python, Devin, GitHub Copilot
