Lead Java Developer

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

Position Responsibilities:

• Lead the design, development, optimization, and
  support of scalable Java and Spring Boot microservices for high-traffic
  e-commerce applications.

• 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.

• 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.
