Original job description

About the Job: Infoya is seeking a hands-on Lead Java Developer who is already operating at a technical lead level and demonstrates the curiosity, judgment, and enthusiasm to grow into broader architecture ownership. This role will help shape efficient, scalable solutions by connecting business needs, application design flows, integration patterns, and cloud architecture with high-quality engineering execution.

The ideal candidate combines deep Java and Spring expertise with strong systems-design capability. You will remain close to the code while guiding solution design, reviewing technical decisions, mentoring developers, and collaborating with product, engineering, infrastructure, architecture, and business stakeholders.

Office Location: Toronto

Employment Type: Permanent

Role Type: New position – current requirement

Work Arrangement: Hybrid (2 days in office)

Position Responsibilities:

Lead the design, development, optimization, and support of scalable Java and Spring Boot microservices for high-traffic e-commerce applications.
Translate business and product requirements into clear application flows, component designs, integration patterns, and pragmatic technical solutions.
Contribute to application, integration, API, and data architecture standards across the e-commerce portfolio.
Design secure RESTful APIs, event-driven services, distributed workflows, and resilient integrations using technologies such as Pub/Sub, Kafka, or RabbitMQ.
Evaluate and recommend frameworks, databases, cloud services, and architectural patterns based on scalability, reliability, maintainability, security, and cost.
Review solution designs, code, and technical documentation; identify risks early and support architecture governance and design-quality practices.
Partner with product, engineering, QA, DevOps, infrastructure, architecture, and business teams to drive efficient solutioning and delivery.
Provide technical leadership through mentoring, design reviews, code reviews, troubleshooting, and knowledge sharing.
Drive modernization and cloud-migration initiatives, including the decomposition of legacy or monolithic applications into cloud-native services.
Build for security, compliance, observability, high availability, performance, and production resilience from the outset.
Investigate complex production issues, conduct root-cause analysis, and improve platform stability and performance.
Evaluate emerging technologies and architectural patterns, validating their practical value through prototypes or proof-of-concept work when appropriate.

Requirements

Required Qualifications:

Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
10+ years of software development experience, with substantial hands-on expertise in Core Java, low-level Java concepts, Java evolution and the latest Java versions, and Spring Boot.
Demonstrated experience operating as a Lead Developer, Technical Lead, or senior engineer with ownership of design decisions and technical direction.
Strong understanding of application architecture, end-to-end design flows, microservices, distributed systems, design patterns, and API-led integration.
Hands-on experience designing and building secure RESTful APIs and event-driven applications.
Strong experience with Google Cloud Platform and cloud-native services; comparable AWS or Azure experience may be considered where supported by strong GCP capability.
Experience with SQL and NoSQL databases, data modelling, query optimization, indexing, caching, and performance tuning.
Experience with Docker, Kubernetes, CI/CD pipelines, and production deployment practices.
Working knowledge of OAuth2, OpenID Connect, JWT, API security, encryption, and secure coding practices.
Strong communication skills and the ability to explain technical trade-offs clearly to both technical and non-technical stakeholders.

Preferred Qualifications:

Experience designing or modernizing high-volume e-commerce, retail, financial-services, or other transaction-intensive platforms.
Understanding of e-commerce domains such as product catalogue, pricing, promotions, inventory, cart, checkout, order management, payments, fulfilment, and customer identity.
Experience with reactive programming, including Spring WebFlux.
Experience influencing architecture roadmaps, technical standards, and modernization strategy without losing hands-on delivery focus.
Exposure to additional backend technologies such as Node.js, Python, .NET Core/C#, or Go.

Benefits

Salary Range: $110,000 to $115,000 CAD/ year

The final compensation offered will depend on local market conditions and geographic location, as well as job-related factors such as the candidate’s knowledge, skills, qualifications, relevant experience, and education/training. Compensation may also include additional components such as benefits, and/or other incentives, where applicable. In accordance with new employment standards requirements, we retain copies of this job posting and applicant information for three (3) years after the posting is removed. We do not use AI technology; all applications are also reviewed by our recruitment team.

Infoya is an equal opportunity employer committed to diversity and inclusion. We welcome applications from all qualified individuals, regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, protected veteran status, aboriginal status, or any other legally protected factors.
